“Pangolin” also known as scaly anteaters, are  mammals. The name comes from the  Malay  word  pengguling meaning “one who rolls up” from  guling  or giling “to roll”; it was used for the Sunda pangolin  (Manis javanica). However, the modern name is  tenggiling. In Javanese, it is terenggiling, and in the  Philippine languages, it is goling, tanggiling, or balintong (with the same meaning).
In ancient India, according to Aelian, it was known as the  phattáges  (φαττάγης).
Pangolins belong to the order Pholidota. This name of order Pholidota comes from an Ancient Greek word Φολιδωτός – “clad in scales” from φολίς pholís “scale”. The  Family is Manidae and has three genera:  Manis,  Phataginus, and Smutsia.
The genus “Manis”- comprises four species found in Asia. Genus Phataginus and Smutsia  include two species each. These two species are found in sub-Saharan Africa. Thus, numbering about eight species of these armoured placental mammals .They range in size from 30 to 100 cm (12 to 39 in or 1 to 3 feet) long exclusive of the tail and weigh 5 to 27 kg (10 to 60 pounds). Across all eight species, adult tail length ranges from about 26 to 70 cm (approximately 10 to 28 inches). The whole of their body is covered with scales except for the sides of the face and underside of the body .
When threatened, they either curl into a ball or use other protective methods to deterent the enemy.
They are nocturnal and have poor eyesight, they rely on hearing and sense of smell to locate their prey.
They are found in tropical Asia and Africa. Some like the African black-bellied pangolin (P. tetradactyla, also classified as M. longicaudata) and the Chinese pangolin (M. pentadactyla), are almost entirely arboreal; others, such as the giant ground pangolin (Smutsia gigantea, also classified as M. gigantea) of Africa, are terrestrial. All are nocturnal and able to swim a little. Terrestrial forms live in burrows. They feed mainly on termites but also eat ants and other insects. They locate prey by smell and use their forefeet to rip open nests.

SPECIES OF PANGOLIN
Pangolins are most hunted by poachers especially for their meat and scale. Several species of this animal had gone extinct  as at date. As of January 2020, there are eight species of pangolin whose  conservation status is listed in the threatened tier. Four of the eight species are found in south Asia and four in Africa
-Sunda pangolin (Manis javanica), -Temminck’s or ground pangolin (Smutsia temminckii),

-Philippine pangolin (Mania culionensis), giant ground pangolin (Smutsia gigantea),

-White-bellied or tree pangolin (Phataginus tricuspis), -African black-bellied or long-tailed pangolin (Phataginus tetradactyla),
-Indian pangolin (Manis crassicaudata),
-Chinese pangolin (Manis pentadactyla)
Chinese, Sunda and Philippine pangolins are Critically Endangered, giant ground, white-bellied and Indian pangolins are Endangered and Temminck’s, and black-bellied pangolins are Vulnerable ( Refer to fig 11 below)

ENDANGERED SPECIES

Out of the eight species of pangolin,
Three (Manis culionensis, M. pentadactyla and M. javanica) are critically endangered, three (Phataginus tricuspis, Manis crassicaudata and Smutsia gigantea) are endangered and two (Phataginus tetradactyla and Smutsia temminckii) are vulnerable on the Red list of Threatened Species of the International Union for Conservation of Nature.
In September 2023, nine species were reported to have not gone extinct.
Major reasons for their extinction include hunting and illegal wildlife, trade and habitat loss.

DIFFERENCE BETWEEN PANGOLIN AND OTHER SCALY MAMMALS
Pangolins were once grouped with the true anteaters (scaly anteater), sloths, and armadillos in the order Edentata, mainly because of superficial likenesses to South American anteaters. Pangolins differ from edentates, however, in many fundamental anatomic characteristics.

DESCRIPTION
i. SCALE: Pangolins are mammals with large, protective keratin scales, similar in material to fingernails and toenails and are structurally and compositionally very different from the scales of reptiles. The plate-like scales are found all over their bodies, except their faces and underbelly. They overlap and are brownish in colour. Inbetween the scales are composed of cemented hairs. They are the only known mammals with this feature. The hardened, overlapping, plate-like scales are soft on newborn pangolins, but harden as the animal matures.  The scaled body is comparable in appearance to a pine cone.

HEAD: The head is short and conical, with small thickly lidded eyes and a long toothless muzzle; the tongue is wormlike and can extend up to 25 cm (10 inches) in length. They have very poor vision and also lack teeth. They rely heavily on smell and hearing, and they have other physical characteristics to help them eat ants and termites.
THE LEG: Their skeletal structure is sturdy and they have strong front legs used for tearing into termite mounds. These legs are short, and with five-toes. Each has sharp claw.
They use their powerful front claws to dig into trees, soil, and vegetation to find prey, then proceed to use their long tongues to probe inside the insect tunnels and to retrieve their prey.
They also possess a prehensile tail, and, with the hind legs, it forms a tripod for support.
The structure of their tongue and stomach is key to aiding pangolins in obtaining and digesting insects. The tongues are extremely long, and like those of the giant anteater and the tube-lipped nectar bat, the root of the tongue is not attached to the hyoid bone but is in the thorax between the sternum and the trachea. Large pangolins can extend their tongues as much as 40 cm (16 in), with a diameter of only about 0.5 cm (1⁄5 in).
Their saliva is sticky, causing ants and termites to stick to their long tongues when they are hunting through insect tunnels. Without teeth, pangolins also cannot chew; but while foraging, they ingest small stones (gastroliths), which accumulate in their stomachs to help to grind up ants. This part of their stomach is called the gizzard, and it is also covered in keratinous spines. These spines further aid in the grinding up and digestion of the pangolin’s prey.
TAIL: Some species, such as the tree pangolin, use their strong,  prehensile tails to hang from tree branches and strip away bark from the trunk, exposing insect nests inside.

When pangolins are threatened, they curl up into a ball, with their overlapping scales acting as armor, while it protects its face by tucking it under its tail. The scales are sharp, providing extra defense from predators. They can also emit a noxious-smelling chemical from glands near the anus, similar to the spray of a skunk to protect themselves from enemy. The secreted foul-smelling odour is released to mark their territory as a deterrent.
Among all the 8 species, the giant ground pangolin is the largest and heaviest of the eight species, and the Indian pangolin is the smallest and lightest. Males are generally larger and heavier than females.

BEHAVIOUR

Most pangolins are nocturnal animals which use their well-developed sense of smell to find insects. The long-tailed pangolin is also active by day, while other species of pangolins spend most of the daytime sleeping, curled up into a ball (“volvation”).
Arboreal pangolins live in hollow trees, whereas the ground-dwelling species dig tunnels to a depth of 3.5 m (11 ft).
Some pangolins walk with their front claws bent under the foot pad, although they use the entire foot pad on their rear limbs. Furthermore, some exhibit a bipedal stance for some behavior, and may walk a few steps bipedally. Pangolins are also good swimmers.
As solitary animals, they meet only to mate. The gestation period depends on the species, but all give birth to a single offspring. A young pangolin stays with its mother for around three to four months and grips onto her tail while foraging for insects.
Pangolins live and give birth in hollow trees, the spaces between large rocks, or in underground burrows, depending on the species.

HABITAT
Pangolins can be found in tropical and sub-tropical forests, thick bush, grasslands and open savannah, semi-arboreal. Some species of pangolin live in hollow trees, while some in burrows. They are nocturnal, and their diet consists of mainly ants and termites, which they capture using their long tongues. They tend to be solitary animals, meeting only to mate and produce a litter of one to three offspring, which they raise for about two years. Pangolins superficially resemble  armadillos, though the two are not closely related; they have undergone convergent evolution.

DIET

Pangolins are carnivorous/insectivorous mammal with very poor vision. Most of their diet consists of various species of ants and termites and may be supplemented by other insects, especially larvae. They lack teeth. They are somewhat particular and tend to consume only one or two species of insects, even when many species are available. A pangolin can consume 140–200 g (5–7 oz) of insects per day. They use their sense of smell  and  hearing, and they have other physical characteristics to help them search and eat ants and termites. Their strong front legs is used for tearing into termite mounds. They also use their powerful front claws to dig into trees, soil, and vegetation to find prey, then proceed to use their long tongues to probe inside the insect tunnels and retrieve the prey.
Pangolins are an important regulator of termite populations in their natural habitats.

FOOD DIGESTION BY PANGOLIN
The structure of their tongue and stomach is key to aiding pangolins in obtaining and digesting insects preys. They possess a sticky saliva and used when feeding. Ants and termites get sticked to their long tongues using the saliva. They penetrate the insect tunnels using their long tongue to hunt insects.
They use both teeth and small stones in their guts to break down insects in their mouth and stomach respectively. They use the teeth in their mouth to chew the insects. While foraging, they ingest small stones (gastroliths), which accumulate in their stomachs. These stones are further used to help grind up ants as it gets digested in the stomach. This takes place in part of their stomach called the gizzard. The gizzard is also covered in keratinous spines. These spines further aid in the grinding up and digestion of the pangolin’s prey.
Apart from the tongue used for feeding in insect tunnels, some species, such as the tree pangolin, use their strong, prehensile tails to hang from tree branches and strip away bark from the trunk, exposing insect nests inside the tree, then uses their tongue to feed on their preys.

DEFENCE MECHANISM
Their means of defense are the emission of an odorous secretion from large anal glands and the ploy of rolling up, presenting erected scales to the enemy. Still, larger predators such as  leopards,  lions,  tigers, and  hyenas  are sometimes strong enough to penetrate the pangolin’s armour. Pangolins are timid and live alone or in pairs. In most species, only one young is born at a time, though broods of two or three offspring have been observed in some Asian species. Young pangolins are soft-scaled at birth and are carried on the female’s back for some time. Life span in the wild is unknown; however, some captive animals have lived as long as 20 years.

FACTORS BEHIND PANGOLIN FARMING AND TRADE ( BENEFITS)
The factors behind pangolin farming are the benefits it offers making farmers to have interest in its production:
i. DEMAND FOR MEAT: Pangolins are hunted for their meat, which is consumed in some communities.
ii. DEMAND FOR MEDICINAL USE: Scales are highly sought after in traditional medicine, particularly in Asia, for their perceived medicinal properties. The local healers use them as a source of traditional medicine. Scientific evidence shows the scales are made of keratin, the same substance as human fingernails and hair.
For example, Pangolins are in high demand in southern China and Vietnam because their scales are believed to have medicinal properties in traditional Chinese and Vietnamese medicine.
iii. CONSERVATION CHALLENGES: The combination of high demand, the pangolin’s natural defense of curling into a ball, and habitat loss has made them the most trafficked mammal in the world. 
iv. A Philippine pangolin pup and its mother, a critically endangered species endemic to the Palawan island group. It is threatened by illegal poaching for the pangolin trade to China and Vietnam, where it is regarded as a luxury medicinal delicacy.
v. Pangolins are also hunted and eaten in Ghana and are one of the more popular types of bushmeat, .
vi. A 2025 study in Nature Ecology and Evolution found that opportunistic hunting for meat, rather than hunting for scales used in traditional medicine, is the primary driver of pangolin population declines in countries like Nigeria.
vii. Though pangolins are protected by an international ban on their trade, populations have suffered from illegal trafficking due to beliefs in East Asia that their ground-up scales can stimulate lactation or cure cancer or asthma.
viii. In November 2010, pangolins were added to the Zoological Society of London’s list of evolutionarily distinct and endangered mammals.  All eight species of pangolin are assessed as threatened by the IUCN, while three are classified as critically endangered. Thus, they are now protected and their population now increasing due to people farming them.
ix. It serves as a clothing material. For example, in 1875–1876, a coat of armour made of gilded pangolin scales from India, was presented to the then Prince of Wales, the later Edward VII.
x. Pangolins have significantly decreased immune responses due to a genetic dysfunction, making them extremely fragile.

xi. Used in movies like that in 2017, where Jackie Chan made a public service announcement called WildAid: Jackie Chan and Pangolins (Kung Fu Pangolin).
xii. In December 2020, a study found that it is “not too late” to establish conservation efforts for Philippine pangolins (Manis culionensis), a species that is only found on the island province of Palawan.
benefits
xiii. Pangolin scales and flesh are used as ingredients for various traditional Chinese medicine preparations
While no scientific evidence exists for the efficacy of those practices, and they have no logical mechanism of action, their popularity still drives the black market for animal body parts, despite concerns about toxicity, transmission of diseases from animals to humans, and species extermination.  The ongoing demand for parts as ingredients continues to fuel pangolin poaching, hunting and trading.
xiv. The first record of pangolin scales occurs in Ben Cao Jinji Zhu (“Variorum of Shennong’s Classic of Materia Medica”, 500 CE), which recommends pangolin scales for protection against ant bites
xv. The scales can be burnt and used as a cure for people crying hysterically during the night.
xvi.  During the Tang dynasty, a recipe for expelling evil spirits with a formulation of scales, herbs, and minerals appeared in 682, and in 752.
Pangolin scales where used.
xvii. In Asia, pangolin scales where used to stimulate milk secretion in lactating women, one of the main uses today, was recommended in the Wai Tai Mi Yao (“Arcane Essentials from the Imperial Library”).

xviii. In the Song dynasty, the notion of penetrating and clearing blockages was emphasized in the Taiping sheng hui fan (“Formulas from Benevolent Sages Compiled During the Era of Peace and Tranquility”), compiled by Wang Huaiyin in 1992. This was achieved using pangolins.
xix. In the 21st century, the main uses of pangolin scales are quackery practices based on unproven claims the scales dissolve blood clots, promote blood circulation, or help lactating women secrete milk.
xx.  The supposed health effects of pangolin meat and scales claimed by folk medicine practitioners are based on their consumption of ants, long tongues, and protective scales.
xxi. The Pharmacopoeia of the People’s Republic of China included Chinese pangolin scales as an ingredient in traditional Chinese medicine formulations. Pangolins were removed from the Pharmacopoeia starting from the first half of 2020. Although pangolin scales have been removed from the list of raw ingredients, the scales are still listed as a key ingredient in various medicines.
xxii. Pangolin parts are also used for medicinal purposes in other Asian countries such as India, Nepal and Pakistan. In some parts of India and Nepal, locals believe that wearing the scales of a pangolin can help prevent pneumonia. Pangolin scales have also been used for medicinal purposes in Malaysia, Indonesia and northern Myanmar. Indigenous people in southern Palawan, Philippines, have held the belief that elders could avoid prostate illnesses by wearing belts made with the scales.
xxiii. BIOLOGICAL PEST CONTROL AGENTS: Pangolins eat termites and ants so they contribute to the regulation of insect populations which if not kept in check can cause damage to vegetation and crops.
xxiv. IMPROVE SOIL FERTILITY: Because they spend so much time digging – either for food or to excavate underground burrows to sleep and give birth in – they play an important role in mixing and moving soil around, which releases nutrients and helps maintain the fertility of the soil.

CONCERNS ABOUT PANGOLIN FARMING

Pangolin farming is controversial and likely counterproductive to conservation due to concerns about illegal laundering, its inability to meet demand, and potential negative impacts on wild populations. The practice is seen by some as a way to profit from the illegal trade, but experts warn it could incentivize poaching, fail to reduce pressure on wild populations due to low survival rates, and introduce diseases. The high demand for pangolin parts for traditional medicine, even though their scales are just keratin, drives this illegal trade and is a major reason for the species’ critically endangered status. 

1. A COVER FOR ILLEGAL TRADE:  Farming operations can be used to launder wild-sourced scales, making them appear to be legally farmed and fueling further poaching and trafficking.

2. INCENTIVIZES POACHING: The high value of pangolin parts incentivizes both wild harvesting and the capture of animals to start captive breeding programs, adding pressure on wild populations.

3. LOW SURVIVAL RATES: Pangolins have a low survival rate in captivity, which means that farming operations would need to continuously source animals from the wild to maintain their stock.

4. DISEASE RISK: High-density breeding of pangolins could increase the risk of spreading and mutating diseases, including coronaviruses, to both other pangolins and humans.

5. INTERNATIONAL TRADE BANS:  Commercial trade is already banned under international law, making any large-scale farming for export illegal and impractical. 

REPRODUCTION

Pangolins are solitary and meet only to reproduce. Their mating typically taking place at night after the male and female pangolin meet near a watering hole. Males are larger than females, weighing up to 40% more. While the mating season is not defined, they typically mate once each year, usually during the summer or autumn. Rather than the males seeking out the females, males mark their location with urine or feces and the females find them. If competition over a female occurs, the males use their tails as clubs to fight for the opportunity to mate with her.

GESTATION  PERIODS: This differ by species, ranging from roughly 70 to 140 days. 
African pangolin females usually give birth to a single offspring at a time, but the Asiatic species may give birth to from one to three. 

BIRTH OF THE BABY PROGOLIN
WEIGHT AT BIRTH: The baby at birth do weigh about  80 to 450 g (2+3⁄4 to 15+3⁄4 oz), and the average length is 150 mm (6 in).
At the time of birth, the scales are soft and white. After several days, they harden and darken to resemble those of an adult pangolin. During the vulnerable stage, the mother stays with her offspring in the burrow, nursing it, and wraps her body around it if she senses danger. The young cling to the mother’s tail as she moves about, although, in burrowing species, they remain in the burrow for the first two to four weeks of life. At one month, they first leave the burrow riding on the mother’s back. Weaning takes place around three months of age, when the young begin to eat insects in addition to nursing. At two years of age, the offspring are sexually mature and are abandoned by the mother.

CHALLENGES DURING FARMING AND IN THE WILD
i. The overexploitation of pangolins come from hunting pangolins for game meat and the reduction of their forest habitats due to deforestation caused by timber harvesting.
ii. They are susceptible to diseases such as pneumonia and the development of ulcers in captivity, complications that can lead to an early death. 
iii. Pangolins rescued from illegal trade often have a higher chance of being infected with parasites such as intestinal worms, further lessening their chance for rehabilitation and reintroduction to the wild.
iv . 100,000 are estimated to be trafficked a year to China and Vietnam, amounting to over one million over the past decade. This makes them the most trafficked animal in the world.
v. The trafficking coupled with deforestation, has led to a large decrease in the numbers of pangolins. Some species, such as Manis pentadactyla have become commercially extinct in certain ranges as a result of overhunting.
vi. China had been the main destination country for pangolins until 2018, where it was surpassed by Vietnam. In 2019, Vietnam was reported to have seized the largest volumes of pangolin scales, surpassing Nigeria that year.
vii. In the past decade, numerous seizures of illegally trafficked pangolin and pangolin meat have taken place in Asia.
 In one such incident in April 2013, 10,000 kg (22,000 pounds) of pangolin meat were seized from a Chinese vessel that ran aground in the Philippines.
viii. In another case in August 2016, an Indonesian man was arrested after police raided his home and found over 650 pangolins in freezers on his property. The same threat is reported in Nigeria, where the animal is on the verge of extinction due to overexploitation.
ix. The nucleic acid sequence of a specific receptor-binding domain of the spike protein belonging to coronaviruses taken from pangolins was found to be a 99% match with SARS coronavirus 2 (SARS-CoV-2), the virus which causes COVID-19 and is responsible for the COVID-19 pandemic.
 Researchers in Guangzhou, China, hypothesized that SARS-CoV-2 had originated in bats, and prior to infecting humans, was circulating among pangolins. The illicit Chinese trade of pangolins for use in traditional Chinese medicine was suggested as a vector for human transmission. However, whole-genome comparison found that the pangolin and human coronaviruses share only up to 92% of their RNA. Ecologists worried that the early speculation about pangolins being the source may have led to mass slaughters, endangering them further, which was similar to what happened to Asian palm civets during the  SARS  outbreak. It was later proved that the testing which suggested that pangolins were a potential host for the virus was flawed, when genetic analysis  showed that the spike protein and its binding to receptors in pangolins had minimal effect from the virus, and therefore were not likely mechanisms for COVID-19 infections in humans.

x. In 2020, two novel RNA viruses distantly related to pestiviruses and coltiviruses have been detected in the genomes of dead Manis javanica and Manis pentadactyla. To refer to both sampling site and hosts, they were named Dongyang pangolin virus (DYPV) and Lishui pangolin virus (LSPV). The DYPV pestivirus was also identified in Amblyomma javanense nymph ticks from a diseased pangolin.
xi. In addition to pestiviruses and coltiviruses, genomic surveys of healthy pangolins have revealed the presence of multiple potentially zoonotic viruses, including coronaviruses, flaviviruses, and circoviruses, indicating that pangolins naturally harbor diverse viral communities without showing disease symptoms.

SOLUTIONS TO THE CHALLENGES

1. As a result of increasing threats to pangolins, mainly in the form of illegal, international trade in pangolin skin, scales, and meat, these species have received increasing conservation attention in recent years. As of January 2020, the IUCN considered all eight species of pangolin on its Red List of Threatened Species as threatened. The IUCN SSC Pangolin Specialist Group launched a global action plan to conserve pangolins, dubbed “Scaling up Pangolin Conservation”, in July 2014. This action plan aims to improve all aspects of pangolin conservation with an added emphasis on combating poaching and trafficking of the animal while educating communities on its importance.

2. Another suggested approach to fighting pangolin (and general wildlife) trafficking consists in “following the money” rather than “the animal”, which aims to disrupt smugglers’ profits by interrupting money flows. Financial intelligence gathering could thus become a key tool in protecting these animals, although this opportunity is often overlooked.
3. In 2018, a Chinese NGO launched the Counting Pangolins movement, calling for joint efforts to save the mammals from trafficking. Wildlife conservation group TRAFFIC has identified 159 smuggling routes used by pangolin traffickers and aims to shut these down.

3. Many attempts have been made to breed pangolins in captivity, but due to their reliance on wide-ranging habitats and very particular diets, these attempts are often unsuccessful. 

4. STEPS TAKEN IN TAIWAN
Taiwan is one of the few conservation grounds for pangolins in the world after the country enacted the 1989 Wildlife Conservation Act. The introduction of Wildlife Rehabilitation Centers in places like Luanshan (Yanping Township) in Taitung and Xiulin townships in Hualien became important communities for protecting pangolins and their habitats and has greatly improved the survival of pangolins. These centers work with local aboriginal tribes and forest police in the National Police Agency to prevent poaching, trafficking, and smuggling of pangolins, especially to black markets in China. These centers have also helped to reveal the causes of death and injury among Taiwan’s pangolin population. Today, Taiwan has the highest population density of pangolins in the world.

5. In 2016, a treaty of over 180 governments announced an agreement that would end all legal trade of pangolins and further protect the species from extinction. However, illegal trade of the species continues. WWF works to protect species from wildlife crime. In Asia, work were on going to reduce consumer demand for illegal wildlife products with campaigns and partnerships with governments and businesses.

6. In June 2020, China increased protection for the native Chinese Pangolin (Manis pentadactyla) to the highest level, which closed an important loophole for consumption of the species in-country. Additionally, the government would no longer allow the use of pangolin scales in traditional medicine, a big win given that an estimated 195,000 pangolins were trafficked in 2019 for their scales alone (Challender, et. al, 2020).

7. You can help report pangolin products for sale online through the Coalition to End Wildlife Trafficking Online’s reporting form or Coalition member companies’ reporting links.

8. In a conference held in 2016 in Johannesburg, South Africa, Dire was a persecutor of the 8 group of animals that delegates at the 17th meeting of the Conference where Parties to the Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora , all parties at the conference voted to impose a ban on the international trade of all pangolins and their parts in that year.

In conclusion, the idea of farming pangolins to reduce the number being illegally trafficked is being explored with little success. The third Saturday in February is promoted as World Pangolin Day by the conservation NPO Annamiticus. World Pangolin Day has been noted for its effectiveness in generating awareness about pangolins.

Knowledge is the application of data and information in a practical context. In agriculture, knowledge constitutes a valuable intangible asset for creating and sustaining the level of production, profitability and creating competitive advantages. Knowledge is what farmers and managers use to understand what information means for their particular situation and how they can use it to optimize processes such as planting, irrigation and harvesting etc. This can be achieved through research findings, used to improve yields or applying agronomic principles to maximize profits.
This knowledge from the research findings are usually shared among agricultural stakeholders like farmers so as to make it relevant as a sustainable agricultural practices.
Technology is one of the many factors that affect the sharing of this knowledge in agriculture. The sharing of these knowledge also constitutes a major challenge in the field of knowledge management  because some researchers tend to resist sharing their knowledge with the rest of the agricultural stakeholders. They believe that by sharing this knowledge, it may be stolen and used for personal gain, few farmers will also adopt it due to others adamancy. Knowledge management also is supported by tools for sharing and collaboration, such as knowledge management systems and online community forums.

THE MAJOR STAKEHOLDERS IN AGRICULTURAL KNOWLEDGE MANAGEMENT (AKM) AND SHARING (AKS).

The main stakeholders in agricultural knowledge management and sharing include Farmers,  Researchers,  Extension/Advisory Services,  Policymakers,  Private Sector (Input Dealers, Marketers, Tech Providers), NGOs/Civil Society, and Educational Institutions, all forming interconnected innovation systems (Agricultural Innovation Systems – AIS) to generate, share, and apply knowledge for better practices and sustainability. Their activities also bridge the gaps between science and practice. 

PRIMARY STAKEHOLDERS (DIRECTLY INVOLVED IN KNOWLEDGE FLOW)

The primary stakeholders who are directly involved in knowledge flow include:

i. FARMERS/PRODUCERS: These are the producers of Agricultural produce. They are the ultimate users and source of tacit/practical knowledge. They need access to new information for sustainable production practices and profitability and also sharing their experiences and challenges for better solution.

ii. AGRICULTURAL RESEARCHERS/SCIENTISTS: These are the experts that generate formal and scientific knowledge (for example., develop new crop varieties, pest control options, new breeds of animals etc). They also recieve the experiences and challenges of the farmers and provide solutions to them.

iii. EXTENSION AND ADVISORY SERVICES: These are the agents who crucially link the researchers or scientist with the farmers. They translate the research findings into usable advice to the farmers. They also collect and take the farmers experience, challenges and needs back to the researchers. Thus, they are called extension agents. 

SUPPORTING STAKEHOLDERS (FACILITATE AND INFLUENCE)

i. POLICYMAKERS/GOVERNMENT: They are the bureaucractic law makers who create enabling environments for the primary and other stakeholders. They make policies, and provide funding for agricultural development within their country.

ii. PRIVATE SECTOR: These are the stakeholders who pull their personal resources together to produce various inputs required for agricultural production. They range from input suppliers (seeds, fertilizer) to marketers, agribusinesses, and technology developers (ICT) etc.

iii. NGOs AND DEVELOPMENT ORGANIZATIONS: These are the Non Governmental Organizations who implement projects, reach out to remote farmers, and mediate knowledge.

iv. EDUCATIONAL INSTITUTIONS: These are institutions that train future professionals, conduct research, and host learning platforms (For example, agricultural schools where interested individuals in the field of agriculture are trained to aquire knowledge). 

Other stakeholders include:

i. FARMER GROUPS/ASSOCIATIONS: These are groups of farmers formed, who collectively share knowledge and advocacy.

ii. MEDIA/INFORMATION BROKERS: These individuals package and disseminate information.

iii. CONSUMERS/FOOD CUSTOMERS: These are the individuals that influence demand of the agricultural produce and also practices in the value chain. 

INTERACTION BETWEEN THE STAKEHOLDERS
These groups form Agricultural Innovation Systems (AIS), where collaboration and coordination are vital; for example, researchers develop a new technique and technology, extension agents teach farmers, farmers provide feedback, and private companies supply the inputs needed, all facilitated by digital tools and supportive policies. 

REASONS FOR KNOWLEDGE MANAGEMENT

1. IMPROVED PERFORMANCE: Adopting better techniques leads to higher yields and profits.

2. SUSTAINABILITY: Helps address climate change, conserve resources, and ensure long-term food security.

3. INNOVATION: Fosters new solutions by combining diverse knowledge.

4. RESILIENCE: Equips farmers to adapt to changing markets, pests, and environmental conditions. 

KNOWLEDGE MANAGEMENT PRACTICES
Some of the practices used during agricultural knowledge management include:
i. CODIFICATION: This is the conversion of practical knowledge into accessible formats like manuals, videos, and fact sheets.

ii. DOCUMENTATION: This is the systematic capture of indigenous knowledge, research findings, and success stories and recorded in a book format.

iii. LEAD BY EXAMPLE: This involve encouragement of leadership to model knowledge sharing behaviours so as to facilitate the adoption of the knowledge by relevant stakeholders. 

AGRICULTURAL MANAGEMENT
Agricultural management means systematically planning, operating, and making decisions for farming activities (crops, livestock, resources) to achieve  efficient, profitable, and sustainable production, integrating knowledge from economics, science, engineering, and human behaviour to optimize yields and meet market demands, essentially running a farm like a business. 
It has also being definited as a broader process encompassing the entire lifecycle of knowledge within the agricultural sector, from creation to application.
Some of the tools used for the management include; digital platforms, farm management systems, extension services, and community networks. 

ASPECTS OF  AGRICULTURAL MANAGEMENT:

1. PLANNING AND DECISION-MAKING: When farmers want to start their farming business, they decide on what to grow/raise, how much, when, and how, considering market prices, resources, and environmental factors.

2. RESOURCE ALLOCATION: To start the farming business, the farmers will decide on the resources that will enhance the production. These resources could be human and material resources. Efficient use of the resources such as land, water, labor, machinery, seeds, and fertilizers brings about the yield of the agribusiness.

3. PRODUCTION TECHNIQUES: Several production techniques are embacked upon to make the agribusiness a profitable one. These techniques are applied scientific principles for improving soil health, pest/disease control, planting, irrigation, and animal care.

4. ECONOMIC INTEGRATION: This involves the management of finances, understanding market trends, and ensuring profitability from the sales of the produce.

5. SYSTEM INTEGRATION: Agricultural management combines the knowledge from various disciplines like plant science, animal science, engineering, and economics into a holistic cohesive operation that makes the management operation a successful one.

6. GOAL ORIENTATION: Agricultural management manipulate resources to achieve economic goals (profit) while also considering sustainability and food security. 

In essence, agricultural management is a holistic action that strategically oversight  all farm activities, from planting to harvest and sale, using business principles to maximize output and sustainability, regardless of farm size. 

KNOWLEDGE MANAGEMENT IN AGRICULTURE
Knowledge Management started right from the creation of man when they started finding solutions to their problem. This reveals that a clear indication of knowledge resides in people.
Since knowledge resides in people, it must be documented and shared to help decision-making and problem-solving as it is passed on from one generation to the other. As at today, all over the world, KM has been recognised as a cornerstone for the success of any organisation as it enables the identification, capturing, documentation and dissemination of relevant information.
In African and most developing nation’s agriculture sector, it is relatively a new idea which requires a lot of attention to make positive impact. It is a process of realising, identifying a knowledge gap and finding solutions to reduce the struggle by organisations and people from going in circles.
By defination, knowledge Management (KM) in Agriculture is a systematic process for managing an organization’s or community’s knowledge assets to improve decision-making, innovation, and overall performance in agriculture.
KM has also being defined as the process of identifying, creating, capturing, storing, distributing and effectively using knowledge. 
It is focused on creating systems for capturing, storage, retrieval, and application of both formal (scientific) and informal (tacit, local) agricultural knowledge. It’s examples include: Establishing digital libraries for crop data, setting up agricultural knowledge centers, creating strategies for documenting best practices, and integrating research findings into extension programs.

PROCESSES INVOLVED IN AGRICULTURAL KNOWLEDGE MANAGEMENT

Agricultural Knowledge Management (AKM) involves processes like capturing (tacit farmer wisdom, research), creating/codifying (turning experience into explicit guides), storing (databases, repositories), sharing/transferring (ICT, extension, farmer-to-farmer), and applying (using knowledge for better decisions), all aimed at boosting innovation, efficiency, and sustainability, often using participatory approaches and technology for stakeholders from farmers to researchers. 
The steps involve to achieve the processes include;
a. IDENTIFY NEEDS: Assess specific knowledge gaps and goals.
b. MAP KNOWLEDGE: Understand existing knowledge and where it is lacking.
c. IMPLEMENTATION: Use technology (databases, apps) and human interaction (forums, training).
d. MONITOR AND ADAPTATION: Continuously review and adjust strategies for effectiveness strengthening

Apart from the above processes, some core processes in Agricultural KM include:

i. KNOWLEDGE CREATION AND ACQUISITION: Knowledge can be aquired through capturing /creation. This is achieved by gathering new data, research, and farmer experiences. Some ways of achieving this include:

a. TACIT-TO-EXPLICIT CONVERSION:  Converting farmers’ hands-on experience (tacit) into documented best practices (explicit) through workshops and feedback loops.

b. RESEARCH INTEGRATION:  Generating new, scientifically validated data and integrating it with local knowledge.

ii. KNOWLEDGE CODIFICATION AND STORAGE: Organization/Storage of knowledge can be done through documentation and structuring of the knowledge ( for example, in digital databases, extension centers).

a. DOCUMENTATION: Recording knowledge in manuals, videos, databases, and case studies to prevent loss and ensure accessibility.

b. REPOSITORY BUILDING: Creating digital platforms (like NARIS systems) to organize and manage agricultural information.

iii. KNOWLEDGE SHARING AND TRANSFER: Sharing /dissemination of done by distributing the knowledge using various platforms listed above.

a. PLATFORMS AND NETWORKS:  Using workshops, farmer field schools, online forums, and social media for exchange.

b. EXTENSION SERVICES: Facilitating farmer-to-farmer learning and interaction between farmers, extension officers, and researchers.

c. ICT UTILIZATION: Leveraging mobile apps, web portals, and data systems to disseminate relevant info.

vi. KNOWLEDGE APPLICATION AND UTILIZATION: Application/Utilization of knowledge means putting knowledge into practice on farms for better results ( for example, precision farming, new varieties).

a. INFORMED DECISION-MAKING:  Applying data (for example., pest, climate) and research findings to optimize planting, irrigation, and harvesting.

b. INNOVATION: Using shared knowledge to develop new techniques and improve yields. 

These processes form a cycle, ensuring that valuable agricultural insights are captured, preserved, spread, and used effectively for sustainable development. 

KNOWLEDGE MANAGEMENT IN AGRICULTURE USING THE DATA-INFORMATION-KNOWLEDGE-WISDOM (DIKW)

Nowadays, the quest to resolve the challenges of global agriculture has being under serious debate. Some of these global challenges, whether it is the need to increase food production while reducing inputs, or the need to better understand complex processes and changing market demands need urgent resolution. To overcome these challenges effectively, it is crucial to understand the relationship between data, information and knowledge and to use them to manage farms and agriculture as a whole. This can simply be stated as:
Data-Information-Knowledge-Wisdom (DIKW).
DIKW is a model used to understand the relationships between data, information, knowledge and wisdom. In the context of agriculture, it is an hierachial relationship used in farm management. This hierarchy helps to decipher how raw data is transformed into valuable information that can be used to generate knowledge for informed decision-making and ultimately lead to wisdom for strategic planning and long-term sustainability.

a. DATA MANAGEMENT: Data management deals with the acquisition, storage and maintenance of data. In agriculture, this includes many aspects such as collecting data from field monitors, satellite imagery and weather sensors. Data can include everything from soil temperature, rainfall, crop data to market prices. Tools such as databases and data management systems are the key tools for information management.

b. INFORMATION MANAGEMENT: Information is data processed in a way that is useful and meaningful. In information processing, data is filtered, sorted and analysed so that it can be used for specific purposes. In agriculture, this might mean translating pest occurrence data on maps into pest control strategies or using historical climate data to predict the best times for planting. Information systems and analytical tools play a major role in information management.

c. KNOWLEDGE MANAGEMENT: Knowledge is the application of data and information in a practical context. Knowledge is what farmers and managers use to understand what information means for their particular situation and how they can use it to optimize processes such as planting, irrigation and harvesting. This can include using research findings to improve yields or applying agronomic principles to maximize profits. Knowledge management is supported by tools for sharing and collaboration, such as knowledge management systems and online community forums.

d. AWARENESS: Wisdom or awareness is the highest level in the DIKW hierarchy, where individuals or organizations use their knowledge and experience to evaluate and understand the context in order to make long-term and sustainable decisions. In agriculture, this refers to the ability of farmers and decision makers to see the long-term picture and plan accordingly, for example when considering the impacts of climate change or when converting to organic farming methods.

This contextual DIKW model assist farm managers to proffer solutions to challenges faced in agribusiness such as the need to increase food production while reducing inputs and adapting to a changing market. They use their understanding about data to convert these data into information, which in turn they converted into knowledge and wisdom for better farm management. Digital technologies such as Farm Management Systems, Precision Agriculture and other innovative tools play a key role in this process. Understanding and using the DIKW hierarchy in agriculture can lead to better decision-making and more efficient and sustainable farming, which is in line with the sustainable development goals (SDGs) and global efforts for sustainable agricultural development.

It can also be defined as the active exchange of ideas, skills, experiences, and information (formal and informal) between individuals and groups, like farmers sharing crop tips or researchers disseminating new techniques. Another definition states that Knowledge Sharing (KS) in Agriculture is the specific act of transferring, communicating, and disseminating knowledge from one party to another.
Knowledge sharing can also be defined as the process of exchanging information, ideas, insights, and experiences between individuals or teams within an organization.
It focuses on the flow and exchange of ideas, experiences, and information between individuals and groups (farmers, extensionists, researchers), with its goal is to collectively build understanding, solve problems, and adopt better methods for improved output and sustainability. 
It is a process whereby various stakeholders in the agricultural sector learn from each other and experts adopt better methods, from regenerative agriculture to quality standards, fostering innovation and efficiency in the sector. 
The stakeholders such as farmers, extension workers, scientists, and policymakers exchange and share knowledge through different communication methods to achieve their goals. The types of Knowledge shared includes; practical “know-how,” tacit knowledge (hard to codify), best practices, and scientific research knowledge.
Examples of KSA include: Workshops, field days, online forums, farmer-to-farmer networks, extension officer visits, and community discussions.
Knowledge sharing can occur through various methods such as conversations, mentoring, training programs, and digital platforms. The key is to ensure that knowledge is easily accessible and disseminated to those who need it, ultimately fostering innovation, collaboration, and growth.

In the digital world, websites and mobile applications enable knowledge or talent sharing between individuals and/or within teams.
Today, IoT services has being included as an easy means of sharing knowledge among people and agricultural stakeholders. The individuals can easily reach the people who want to learn and share their talent to get rewarded.

INFORMATION TECHNOLOGY SYSTEMS (IT): These are common tools that help facilitate knowledge sharing and knowledge management. The main role of IT systems is to help people share knowledge through common platforms and electronic storage to help make access simpler, encouraging economic reuse of knowledge. IT systems can provide codification, personalization, electronic repositories for information and can help people locate each other to communicate directly. With appropriate training and education, IT systems can make it easier for organizations to acquire, store or disseminate knowledge.

FACTORS AFFECTING KNOWLEDGE SHARING
Knowledge is transferred among agricultural stakeholders who are expert in the field of agriculture. These experts design a structural strategy for knowledge transfer so that the agribusiness can thrive.
Several factors affect knowledge sharing in agribusiness, such factors include; agribusiness culture, trust, incentives, individual motivations (trust, self-efficacy, perceived benefits), social & cultural elements (farmer group participation, social networks, trust, organizational culture), technology and infrastructure (ICT access, internet, IT support), and extension services (accessibility, quality, training), with economic factors like farm income also playing a role in willingness to share.
In agribusiness, five distinct conditions of the agribusiness culture have a positive effect on knowledge-sharing:
i. communication and coordination between groups,
ii. trust,
iii. top management support,
iv. the reward system, and
v. openness.

 i. COMMUNICATION AND COORDINATION: Concerning the communication and coordination between groups that make up the stakeholders, stakeholder structure encourages knowledge-sharing. For example, researchers pass their findings to extension agents who desseminate the findings to onsite farmers to test the findings. When a profitable result is achieved, trust is built among the stakeholders, especially farmers.

KNOWLEDGE MANAGEMENT SYSTEMS AS A FORM OF INFORMATION TECHNOLOGY
Drivers for knowledge sharing are connected to both human resources and software. Knowledge sharing activities are commonly supported by knowledge management systems, a form of information technology (IT) that facilitates and organizes information among the agricultural stakeholders.  Knowledge sharing in knowledge management systems can be driven by accountability-inducing management practices.

LEVELING UP ( IMPLEMENTING A KNOWLEDGE-SHARING CULTURE)

Creating the agribusiness culture of knowledge sharing extends beyond just production, processes and tools. It requires a shift in mindset and attitudes. The following are some steps to foster a knowledge-sharing culture:

i. LEAD BY EXAMPLE: Farm owners and their managers should actively engage in knowledge sharing, demonstrating their commitment to the process and encouraging others to follow suit.

ii. EMBRACE DIVERSITY AND INCLUSION: Encourage all farmers, experts and professionals from all backgrounds with different levels of experience to contribute their knowledge and expertise, recognizing that diverse perspectives enrich the collective understanding.

iii. SHARE SUCCESSES AND FAILURES: Promote a learning orientation by openly discussing both positive and negative experiences, fostering resilience and growth.

iv. ALLOCATE TIME AND RESOURCES: Provide all farm workers with the necessary resources and dedicated time to engage in knowledge sharing activities.

IMPLEMENTING KNOWLEDGE SHARING SYSTEMS

Investing in tools and systems that facilitate knowledge sharing is essential for creating an effective knowledge sharing environment. Some popular options include:

i. INTRANETS: Internal websites for sharing news, documents, and resources

ii. DOCUMENT MANAGEMENT SYSTEMS: Platforms for storing, organizing, and retrieving digital documents

iii. KNOWLEDGE MANAGEMENT SYSTEMS (KMS): Comprehensive platforms that capture, store, and share organizational knowledge

iv. COLLABORATION TOOLS: Online platforms that support group communication and project coordination

By providing the right infrastructure for knowledge sharing, shareholders in agribusiness can improve the flow of information and enhance overall productivity.

CHALLENGES OF KNOWLEDGE SHARING

Knowledge sharing can sometimes constitute a major challenge in the field of knowledge management. 
However, despite the many benefits of knowledge sharing, it can be challenging to implement in practice. For example, some individuals may be reluctant to share their knowledge due to a fear of losing their competitive advantage or job security. Additionally, knowledge sharing requires a culture of trust and openness, which may not exist in all organizations.
Other challenges in AKS include poor infrastructure (internet access), low digital literacy, resistance to new methods, ineffective extension services, information overload, and disconnects between researchers, extension workers, and farmers, often rooted in power dynamics and a failure to recognize farmers’ own tacit knowledge.
Some of the major issues hindering knowledge sharing include; siloed information, misaligned incentives, and inadequate funding for management systems. All hinder the flow of vital information on new techniques, market prices, and risks.
The difficulty of knowledge sharing resides in the transference of knowledge from one entity to another.

1. FARMER-LEVEL CHALLENGES
a. LACK OF TRUST: Skepticism towards external sources (researchers, companies) and even fellow farmers is one of the major challenges of knowledge sharing among the stakeholders. Most farmers are adamant to adopt new innovations especially those that are not learnered. Also, when research findings are not presented with concrete results, knowledge sharing might prove difficult. Therefore, to promote knowledge sharing and remove mistrust, the farming culture of an entity should encourage discovery and innovation. Members of the stakeholders who trust each other are willing to exchange knowledge and at the same time want to embrace knowledge from other members as well.
b. RESISTANCE TO CHANGE: Farmers can be hesitant to adopt new practices due to tradition or fear of failure. When these adamant farmers understand the value of knowledge sharing, they become motivated to participate
c. INFORMATION OVERLOAD: Too much conflicting or irrelevant data can be overwhelming. By effectively organizing and filtering these data, individuals are prevented from becoming overwhelmed
d. SAFEGUARDING SENSITIVE INFORMATION: Protecting confidential data while still promoting knowledge sharing ensure futuristic relevance of such data
e. MEASURING SUCCESS STORIES:  Defining and tracking the ROI of knowledge-sharing initiatives
f. DIGITAL DIVIDE: Poor internet and low literacy in rural areas limit access to digital knowledge.
g. TACIT KNOWLEDGE GAP: Difficulty in formalizing and sharing practical, on-the-ground wisdom.

2. SYSTEMIC AND INSTITUTIONAL CHALLENGES
a. WEAK EXTENSION SERVICES: Extension agents do lack funding to carry out their duties. No or inadequate training of these agents and coordination for extension workers, all prove to limit the efficiency of these agents.
b. RESEARCH-EXTENSION DISCONNECT: Top-down research often fails to address real farmer needs, creating a gap.
c. SILOED EFFORTS: Independent NGOs, researchers, and private sector groups often duplicate work and notes due to some factors that limit their efficiency.
d. POLITICAL AND POWER DYNAMICS: Knowledge networks can serve political agendas, marginalizing some farmers.
e. LACK OF INCENTIVES: Insufficient motivation or rewards can limit the sharing knowledge.

3. TECHNOLOGICAL AND METHODOLOGICAL HURDLES
a. INADEQUATE ICT: There is poor implementation and suitability of technology for local contexts. This is due to lack of social amenities in the rural areas.
b. FLAWED DATA COLLECTION: Most methods used for gathering informations and knowledge are usually incomplete or inaccurate. Thus, flowing data collection on knowledge.
c. COMPLEXITY: Most tools used during knowledge aquisition are complex and complicated for researchers, extensionist and ordinary farmers to use. They need special training to learn how to utilize the tools. The methodologies are also very complex to follow.
d. MISINFORMATION: The spread of false information, especially via social media, can cause confusion.

4. ORGANIZATIONAL BARRIERS (WITHIN INSTITUTIONS)
a. LACK OF COMMITMENT: Insufficient top management support for knowledge management.
b. RESOURCE CONSTRAINTS: No dedicated budget for knowledge management programs.
c. INERTIA: Resistance to recognizing the need for change and urgency in knowledge sharing

SOLUTIONS / OVERCOMING THE CHALLENGES OF KNOWLEDGE SHARING
Knowledge sharing in agriculture boosts productivity, income, and sustainability by spreading best practices, fostering innovation (like digital tools), reducing costs, improving market access, and building resilient communities through farmer-to-farmer learning and data insights, leading to better decision-making for challenges like climate change and food security. It helps adopt new techniques, improves skills, and ensures local, relevant solutions thrive.
In addition, a proactive attitude and strategic planning can be used to address these challenges, Thus, making the shareholders successfully promote knowledge sharing and reap its benefits.

i. COMPETITION : Build a supportive culture through peer mentoring and collaborative activities, not individual competition.
ii. TECHNOLOGICAL BARRIERS: Provide training and support to help stakeholders use digital tools effectively; address poor internet connectivity in remote areas.
iii. KNOWLEDGE SILOS AND FRAGMENTATION: Encourage cross-functional collaboration and use integrated knowledge management systems to connect different stakeholders.
iv. LOSS OF TACIT KNOWLEDGE :Use methods like mentorship programs and in-person interactions (for example., field days) to capture and transfer experience-based know-how etc.

DIFFERENCES BETWEEN KNOWLEDGE MANAGEMENT AND KNOWLEDGE SHARING

Using the public library as an illustration, knowledge management is gathering the books and deciding how to organize them on the shelf. Knowledge sharing is creating the process for how to share those books out to the people who need that information. With this simple illustration, it can be stated that
knowledge sharing and management in agriculture involves a systematically capturing, organizing, sharing, and applying insights (from research, experience, data) among farmers, extension workers, researchers, etc who are stakeholders to improve practices, boost productivity, adapt to challenges like climate change, and ensure sustainable food production and marketing systems. It moves data into actionable knowledge, empowering better farm decisions and enhancing livelihoods.

Knowledge sharing or skill sharing is an activity through which knowledge (namely, information, skills, or expertise) is exchanged among people, friends, peers, families, communities, or within or between organizations. It bridges the individual and organizational knowledge, improving the absorptive and innovation capacity and thus leading to sustained competitive advantage of companies as well as individuals. Knowledge sharing is part of the knowledge management process.
It constitutes a major challenge in the field of knowledge management because some employees tend to resist sharing their knowledge with the rest of the organization.

In agriculture, Knowledge Management (KM) is the broad strategy for capturing, storing, organizing, and using knowledge (like scientific data, local wisdom), while Knowledge Sharing (KS) is a key activity within KM, focusing specifically on the act of exchanging that knowledge (e.g., advice, experiences) between farmers, researchers, and extension agents through platforms like farmer groups or digital tools to improve practices and innovation. Essentially, KM creates the system, and KS is the dynamic interaction that fills and utilizes it, boosting productivity and collaboration.
In summary, the difference between both concept include:

1. Scope: KM is the umbrella strategy (the “what” and “how” of knowledge), while KS is a core component or activity within that strategy (the “doing” of knowledge transfer).

2. Action: KM involves building infrastructure (centers, systems) and processes (documentation); KS involves communication, interaction, and collaboration (sharing, discussing).

3. Goal: KM aims for organizational learning and effectiveness; KS directly fosters collaboration, skill development, and innovation through interaction.
In short, knowledge is managed to create an environment where sharing can effectively take place, and sharing is what brings that managed knowledge to life in the field of agriculture.

TERMINOLOGIES
i. KNOWLEDGE TRANSFER: Deliberately integrating systems, processes, routines, etc., to combine and share relevant knowledge.

ii. COMMUNITIES OF PRACTICE: A group of people who share a craft or a profession; usually takes the form of cross organizational or inter-organizational workgroups, in physical, virtual or blended forms[19]

ORGANISATIONS INVOLVED IN KNOWLEDGE MANAGEMENT INITIATIVES AND ITS CHALLENGES
These are knowledge-intensive organisations who proffer solutions to knowledge management challenges. KM challenge is an initiative aimed at building the skills of KM practitioners in Africa and developing countries.  Their overall objective was to enable agricultural research and innovation, including extension services, to contribute effectively to food and nutritional security, economic development and climate change in Africa and the whole world through Knowledge management.
These organizations pushes the agenda of KM in the agriculture sector. They include; the Forum for Agricultural Research in Africa (FARA) headed by the Executive Director, Yemi Akinbamijo. They work jointly with Sub-Regional Agricultural Research organisations, the African Forum for Agricultural Advisory Services (AFAAS), Association for Strengthening Agricultural Research in East and Central Africa (ASARECA), Central African Council for Agricultural Research and Development (CORAF) and the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA) launched the Maiden Continental Knowledge Management for Agricultural Development Challenge.
In a conference organised by Mr Yemi Akinbamijo under the CAADP-XP4 programme, under the theme, ‘Strengthening the knowledge Ecosystem for improved Agricultural productivity in Africa.’ Funded by the European Union (EU) and administered by the International Fund for Agricultural Development (IFAD), Mr Yemi Akinbamijo in the conference stated that
” knowledge is essential because it supports decision making evidence-based planning and is critical for research in generating knowledge”. He also stated the role of agricultural research and development institutions in knowledge generation and dissemination. He said ” knowledge can be used to halt poverty by 2025 through the CAADP Malabo Commitment and contribution to the Sustainable Development Goals (SGDs). He also indicated how well the KM  challenge aims to improve the capture and dissemination of knowledge in African Agricultural by bringing the appropriate capacities, establishing Community of Practice (CoPs), and strengthening knowledge generation.  
The CCARDESA’s Comprehensive Africa Agriculture Development Ex-Pillar IV (CAADP-XP4) programme Coordinator, Dr Baitsi Podisi, stated in a conference that CCARDESA places great importance on KM, adding that it is a whole thematic area in the organisation’s Strategic Plan.
Dr Podisi also said that KM is critical in developing the agricultural sector as the institution positions itself to be the regional broker for agricultural knowledge, adding that CCARDESA will continue to work on its knowledge system, website and mobile app to serve the Farming community. “The subject of KM is crucial to CCAREDSA, and CCARDESA has been working tirelessly to build the capacity of its Information, Communication and Knowledge Management (ICKM) focal point persons in the Southern Africa Development Community (SADC) member states in this area” he emphasised.
To demonstrate the great importance CCARDESA attaches to KM, it nominated five representatives to participate in the KM for agricultural development challenges. Ms Lorato Bailang represented Botswana, Mr Bongani Mvubu represented the Kingdom of Eswatini, Mr Americo Humulane represented Mozambique. Ms Vidah Mahava represented Tanzania and last but not least, Ms Dorcas Kabuya represented Zambia.
And lastly, the Coordinator for the Long-term AU-EU Partnership for Food and Nutrition Security for Sustainable Agriculture (LEAP4FNSSA), Irene Annor-Frempong stated in his own briefing that Africa’s agricultural and food security challenges can only be addressed by locally generated data.
Dr Annor-Frempong further stated the decline in the contribution of African scientists to knowledge creation, adding that if the situation does not change, Africa is headed for doom.

Farmers keep their soil healthy and productive by using methods that help improve soil management. Such methods include; soil fertilization, irrigation and aeration etc. These are primary practices required for lawn management, optimal plant production and development.
Soil aeration is an important practice often underestimated when discussing about soil health and crop production. It affect root growth and healthy vegetation, thus, bringing about high yields.
By definition, soil aeration is the process of creating air pockets in soil, allowing essential gases (like oxygen) to reach roots and microbes, water to drain, and nutrients to penetrate the soil. It is primarily done by perforating compacted soil with tools to promote deep root growth, better drainage, and overall soil health, crucial for plants to “breathe” and thrive. 
Soil aeration processes provides air to the soil from the atmosphere. The supplied O2 and CO2 move between the soil pore spaces and the atmosphere. It helps avoid oxygen starvation in crops and reduce harmful carbon dioxide levels in the subsurface air if they rise too high. It is an important factor plant roots, soil micro and macroorganisms use for respiration. For example, plants uses atmospheric oxygen to respire and release energy for their needs from the glucose-oxygen reaction.
In poorly aerated or waterlogged soils, roots are deprived of oxygen and fade because they cannot breathe properly. However, roots are essential to absorb nutrients and water, so the plant eventually dies.
In aerating the soil, different periods of the year are required to aerate poorly aerated soils. For the cool-season, lawns can best be aerated during the fall and spring. During the fall period, grasses typically put down their roots. While during the spring period, lawn aeration gives the roots all they need to help the grass grow strong and healthy. The soil will be broken up, so the roots receive the necessary amount of water, nutrients, and oxygen.
Apart from the above, during the spring, aerating the lawns ahead of the growing season can prove to be a boon for the lawn. Springtime aeration is often done in conjunction with overseeding grass. Aeration allows these seeds to reach the soil instead of getting caught up in the layer of thatch. Once the seeds are in the soil, they are able to grow and thrive.

REASONS FOR AERATING LAWNS

1. STRONGER ROOTS: More oxygen in the soil brings about deeper roots that can survive during summer droughts.

2. BETTER NUTRIENT UPTAKE: Well aerated soils means the soils have well developed pore spaces that support nutrient uptake. Applied fertilizers will not just sit on top of the soil but or wash into the street, but percolate to the root zones in the soil.

3. LESS RUNOFF: Well aerated soils gives room for water percolation. The water soaks in instead of creating mini-lakes on the lawn.

4. FEWER BALD SPOTS: Compacted soil causes grass to thin out or stop growing in certain areas, thus, creating a bald spot on the ground.

5. HEALTHIER SOIL: Soil aeration encourages earthworms and microbes to keep the lawn thriving and can lead to greener grass.

SIGNS OF POOR AERATION

1. Water pools on the soil surface.

2. Shallow root systems.

3. Plants turn yellowish or wilt, despite watering.

4. High CO2 levels in the soil air. 

CAUSES OF POOR SOIL AERATION

To ensure proper aeration of soil, it is critical to outline what affects and causes it. These causes makes farmers understand how to implement it and mitigate its negative consequences.
The factors affecting soil aeration include:

i. Soil moisture
ii. Soil texture
iii. Infiltration properties
iv. Machinery traffic
v. Organic matter application
vi. Grazing etc.

These factors may lead to soil compaction, excessive carbon dioxide build up, and poor oxygen saturation.

a. SOIL COMPACTION

In most cases, poor soil aeration is caused by compaction. The finer the earth, the more prone it is to compaction. For example, clay soils. The smaller its particles, the more densely they attach to each other, leaving less space for oxygen. When oxygen level is too low in the soil, neither plants nor aerobic earth biota can survive.
Compaction may be an adverse consequence of irrational  irrigation  and other field operations.
Due to compaction, plant roots will not develop properly, causing yield losses on the long run.
The situation is critical when compaction combines with dry weather conditions. In this case, roots not only can not breathe but cannot also absorb water and nutrients. On the contrary, when compaction combines with wet weather conditions, it hampers grazing and promotes soil erosion with fast liquid runoffs.

b. WATERLOGGING

Waterlogging can be caused by natural forces or anthropogenic factors. It is a major factor that tampers with soil aeration. After downpours, floods, or excessive irrigation, water fills up the earth’s pore space, displacing the air and reducing the oxygen level nearly to zero. Thus, the air can no longer penetrate the earth due to the pore spaces occupied with water. However, when the water dries up again, the balance is restored. Water evaporates, and the air gets back to earth.

c. SOIL ORGANIC MATTER

Organic matter boosts soil fertility and improve soil health. Nonetheless, the decomposition of organic matter brings about a strong carbon dioxide release. Correspondingly, when organic matter content is too high, the production of CO2 may be too fast. Consequently, its removal slows down and may reach toxic levels. Also, carbon dioxide retention also interferes with oxygen supply. This oxygen are needed by plant roots and also for exchange of gases between the atmospheric air and the soil. Due to this, it is necessary to add organic matter at moderate level or in an already decomposed state.

d. GRAZING WITH LIVESTOCK

Grazing practices contribute to soil fertility with organic manure released by the animals as they graze. However, trotting around the pasture, animals also cause soil compaction with their hoofs. In this regard, rotational pastures prove to be an efficient problem solution to the effect brought by in grazing.

e. REGULAR VEHICULAR TRAFFIC

Usage of heavy machinery to till farm land contribute to compressed farmland soils, thus, leading to soil compaction. For this reason, the movement of massive field equipment like forage harvesters, manure spreaders, etc., should be limited, and alternative field operations and crop treatment should be employed. Usage of these heavy duty machines can get even worse when the earth is wet.

TOOLS REQUIRED FOR SOIL AERATION
Various soil aeration tools and methods allow maintaining proper air circulation in the subsurface, bringing vital oxygen to the root zone. Some of these tools include,  plug aerators (manual or powered) for removing soil plugs, spike aerators (handheld or spiked shoes) for poking holes, or simpler options like a garden fork, plus prep items like a lawnmower, hose, and markers for irrigation lines. Plug aerators are best for heavy soil, while spike aerators suit lighter soils or quick fixes, but the goal is always to improve air, water, and nutrient flow to the roots. 

SOIL AERATION METHODS

The aim of soil aeration is to supply oxygen to the topsoil to make it available for crop roots and soil microorganisms. Aeration also makes the topsoil softer and improves its infiltration properties. It is carried out with a number of methods, each of which depends on the area scope and land specifics.
Some standard techniques used include : spike, plug (core), and liquid aeration.

a. SPIKE AERATION

The spike aeration method produces the least land disturbance by making holes for the air to penetrate. However, it applicable to a relatively small area due to limited coverage of applicable tools, which include soil aeration shoes, prongs, rollers, and mower attachments. They all contain spikes which can pierce into the soil. The first three options operate by walking or manual operations, by pushing or rolling. On the one hand, they are the least sophisticated. They require considerable physical strength. Mower attachments demand less human efforts since they are adjusted to machinery.
Note: Such a technique is perfect for sandy soils. It is not suitable for clay soils because the clay soil will take the spike shape, which results in compaction.

b. CORE AERATION

The core soil aeration method involves the creation of “cores” or “plugs”. It is relevant for compacted clay soils. Cores consist of clay, roots, thatch, etc., in the topsoil layer. Unlike the previous method, it suggests not piercing the earth but pulling its parts out, leaving them on the surface.
Core aeration makes the field somewhat messy yet has certain advantages. This will be discussed later.

c. LIQUID AERATION

Unlike the core method that work with the soil directly, liquid aeration utilize a liquid aerators which consist of a wetting agent and nourishment for earth-dwelling biota. The wetting agents improve infiltration, and water reaches deeper levels of the soil profile. It enables microorganisms to dig deeper into the soil. By digging, they improve soil aeration and allow water to seep even lower as well, which boosts root development.
Furthermore, liquid aerators contain food for bacteria (mainly seaweed extract) to boost their activity. In its turn, this is beneficial for worms that move underground adding to earth porosity. It helps air and water penetrate farther through the prepared “ways”. Besides, worms and insects process organic matter, Hence, boosting soil fertility.

REASONS TILLAGE IS NOT THE BEST OPTION FOR AERATION

Tilling is the most intensive earth disturbance operation that involve; digging the soil, turning it upside down, and breaking huge parts into smaller pieces. Obviously, tilling operations reduce compaction and enhance oxygen supply, but they are helpful in the short run only. The adverse effects of heavy earth disturbance make this operation to be repeated. Some other effect of tillage include;

i. It disrupte soil health due to risks of wind and water erosion
ii. It destroy beneficial microorganisms (however, tillage also impacts pests and their larvae as part of integrated pest control)
iii. It uncover weed seeds from the subsurface layers (yet, at the same time, tillage places the seeds from the surface underground and destroys weeds, being a mechanical method of integrated weed management);
iv. Polluted atmosphere with fossil fuel emissions from tilling machinery contributes to climate change.
v. It can subject lands to erosion, which is a significant advert consequence of its usage.

HOW DIFFERENT SOIL TYPES AFFECT SOIL AERATION
Typically, there are three types of soil. Such soils include : clay, sand, and silt. These are the three main components of the soil.
Clay soils are soils with fine particles and with small pore spaces. It is perfect to retain nutrients and moisture. Due to its small pore spaces, it absorbs water slowly, so it requires moderate irrigation. Soil aeration is particularly beneficial for clay fields, improving porosity and water absorption.
Sand soils on the other hand is coarse and more gritty with larger pore spaces. It can not retain much nutrients and moisture. The large pore spaces allow quick water loss from the soil.
Apart from the fact that different soil types affect soil aeration, also a decrease in soil aeration depends on the moisture level in the ground, when the soil is fully saturated, this means all the pore spaces are filled with water and no air exist in the soil. This result to an anaerobic condition. But when the water percolate freely through the soil, enough air from the atmosphere enters the soil and the soil becomes productive. Therefore, it is necessary to maintain the optimal moisture content within the soil.
Therefore, waterlogging is among the causes of poor aeration.

IMPORTANCE OF SOIL AERATION

The availability of nutrients to crop root uptake has a direct relationship with the degree of soil aeration. Well-aerated soils (meaning lesser water content ) provide more favorable growth conditions, while nutrient imbalance and poor aeration impede plant development. Therefore, it can be stated that soil aeration has great impact on nutrient supply to plants.
Some of the importance of soil aeration include;

1. OXYGEN FOR ROOTS: Roots need oxygen for respiration to release energy for growth and nutrient/water uptake. Compacted soil suffocates them.

2. NUTRIENT AND WATER ACCESS: Aeration allows water and nutrients to soak deeper into the soil, thus reducing runoff and making them available to roots.

3. MICROBIAL ACTIVITY: Healthy aerobic microbes need oxygen to break down organic matter, releasing nutrients and carbon dioxide.

4. COMPACTION RELIEF: It alleviates soil compaction, a major barrier to root growth and drainage. 

5. BREAKS THATCH LAYERS: Grass, like any other plant, needs water and nutrients to thrive. However, the development of thatch on a lawn makes it difficult for water and nutrients to reach the grass’s roots.
Thatch is a collection of roots, stems, and other plant matter that amasses near the soil. In addition to being a water barrier, thatch is also a hotbed for insects and other pests.
Aeration breaks up this layer of thatch so the grass’s roots can get the water and nutrients they need. It’s also a soil loosener, allowing freshly planted grass seeds to take hold.

IMPACT OF SOIL AERATION ON NUTRIENT SUPPLY TO PLANTS

1. NITROGEN: Organic nitrogen fixation and mineralization are carried out by nitrogen-fixing bacterias living in plants (especially legumes) and soil microorganisms etc. These organisms assist in fixing atmospheric nitrogen to the soil, decompose organic materials and livestock wastes.
Aerobic bacteria assist in breaking down nitrogen containing materials to plant-digestible forms only under sufficient soil aeration.
Poor aeration induces a split of nitrates to nitrous oxide (N2O), which is among the potent gases contributing to the greenhouse effect. Besides, denitrifying bacteria are more likely to deprive crops of nitrates in poor earths. This happens because most denitrifying bacteria are facultative aerobic. It means that when O2 is available, they will use it (aerobic respiration). When the O2 level is poor, they will switch to NO3 or NO2 (anaerobic respiration).

2. MANGANESE  AND  IRON: Both nutrients  have high valence in well-aerated soils and low valence in poorly-aerated ones. Although plants can consume only low-valency forms, their excessive absorption is harmful to crops. For this reason, excessive access to low-valency forms must be limited, and toxicity risks are mitigated with aeration.

3. SULFUR: This nutrient is represented by sulfate in aerated soils, which is suitable for plants. Sulfate turns into sulfide under poor aeration (waterlogging). Hydrogen sulfide is harmful to crops.

Nutrient imbalance results in the deviance of root formation, which will inevitably affect the whole plant and cause yield losses. Signs of poor aeration include thick, short, dark roots of abnormal shapes with poorly developed hairs, etc.

DISADVANTAGES OF INSUFFICIENT AERATION

1. Poorly aerated soils causes; thick, short, dark roots of abnormal shapes with poorly developed hairs, etc.

2. Crops become  higherly susceptibility to pathogens and root-rotting fungi, in particular. Correspondingly, aeration becomes an effective prevention technique, decreasing crop and tree disease risks.

METHODS OF AERATING THE SOIL

1. MECHANICAL AERATION: This involves the use of tools like plug aerators (which pull out soil cores) or spikers/forks to make holes in lawns or gardens.

2. SOIL AMENDMENTS: Add materials like compost, peat moss, sand, or perlite to loosen dense soil, making it well aerated.

3. COVER CROPS: Growing and crimping cover crops can naturally improve soil structure and aeration over time. 

TYPES OF SOIL AERATION
There are different types of soil aeration. But the major ones are the core aeration and the liquid aeration.

A. CORE AERATION
Core aeration is a lawn care practice in which a machine called lawn aerator is used. This machine has hollow tines used to pull small plugs (cores) of soil, thatch, and grass from the ground to relieve compaction and create channels for air, water, and nutrients to reach the roots. It also promote deeper root growth and a healthier, thicker lawn. It is best done in spring or fall when grass is actively growing, leaving the soil plugs on the surface to decompose and enrich the soil, making it superior to spike aeration for significant soil improvement. 
Apart from this machines pulling small plugs in the soil to aerate it, other ways can be used to aerate the lawn. For example, some lawn aerators drive solid tines into the earth. But that method is not considered as effective as core aeration.
It is important to note that core aeration should not be carried out during hot and dry periods of the year. But should be carried out during early spring (March–April). The grasses should be prepared for the stress of summer while also blocking out weeds with thicker turf.  By early fall (September–November), roots would have had enough time to recover before winter.
 It is generally preferred for cool-season grasses like Kentucky bluegrass, fescue, ryegrass or lawns with severe compaction issues. 

BENEFITS OF CORE AERATION

1. It enhances gaseous exchange between the atmosphere and the soil.

2. It intensifys oxygen saturation to the root zone.

3. It raises water infiltration.

4. It improves soil structure.

5. It incorporate organic matter into the soil.

6. Fast improvement 

7. Enhances the absorption of nutrients and water retention 

8. Lessens the accumulation of thatch 

9. Gets the soil ready for fertilization and overseeding 

10. Increases drought resistance and root depth

Core-removing soil aeration equipment includes manual aerators and mower attachments.

ADVANTAGES OF CORE AERATION

1. Holes created for core aeration allow oxygen, water, and fertilizer to penetrate better into the soil, while the plugs break down, adding organic matter. 

2. Relieves Compaction: Loosens hard, compacted soil, especially in clay areas.

3. Deeper Roots: Encourages grass roots to grow deeper and stronger.

4. Manages Thatch: Helps break down thick layers of dead grass.

5. Improves Absorption: Increases water and fertilizer uptake by roots. 

6. Core aeration creates those pockets of air that allow oxygen, water, and nutrients to move through the ground.

7. It Helps With Moss Problems: Moss plants are major challenges growing in lawns eapecially when some areas of the lawn are saturated with water or pool of water forms on it. Most of the managers of the lawns believe the only way to stop this growth of moss is by applying herbicide. This is a misguided policy. When lawns drain poorly due to compacted soil and/or thatch might be displaying “Moss challenge.” Compacted soil is a common problem for lawns subjected to excessive foot traffic (as when kids play on the lawn frequently).

DISADVANTAGES OF CORE AERATION

If not done at the right time, even the best-laid lawn care plans can backfire. Avoid using the aerator in periods of intense heat or drought (your grass is already under stress), freezing temperatures (frozen soil can ruin aerator tines), and periods of soggy, wet weather (you’ll only worsen compaction). 

LIQUID SOIL AERATION

Liquid soil aeration is a technique used in agriculture and lawn care to enhance soil quality by applying a liquid solution directly to the soil.
The goal is to breakup compacted soil and enhance water penetration and improve soil structure without using heavy machinery.
Lawns are used for recreation and sports etc and it requires different management practices to keep it available for its purposes. Some of the management operations
required for it to achieve its tasks include; mowing, fertilizing, and clearing them of leaves and debris. Also, an important operation most people overlook in the management of this lawn is soil aeration.
Aeration is an essential aspect of lawn care. Core aeration and liquid soil aeration are best used for lawn aeration.
Liquid soil aeration is a lawn treatment that sprays a solution, often with surfactants, humates, and enzymes, onto compacted soil to break it down at a microscopic level, improving water, oxygen, and nutrient penetration for healthier roots, without removing soil plugs like traditional methods. It is easier and less disruptive, creating micro-channels for better soil health, but often requires repeated applications for lasting results. Typically, It can be applied with a hose-end or pump sprayer for even coverage. After application, gradually it began to show its effectiveness. The effect can be seen over weeks or months as the soil structure changes. 
The best times for liquid aeration is during late spring to early summer (April–June). That is, right before grass starts growing more quickly. By early fall  (September – October), grasses would begin to put down roots as the soil becomes slightly cooler . 
Liquid soil aeration is usually recommended for warm-season grasses like Bermuda, Zoysia, St. Augustine or lawns with mild to moderate compaction issues.

SUBSTANCES REQUIRED TO PREPARE THE LIQUID.
Liquid soil aeration is an innovative alternative to traditional core aeration featuring a specialized liquid spray that loosens soil over time at the microscopic level and encourages microbial activity. It may take longer to work, but it often delivers more effective results.
The formulated liquid solution can be applied using a sprayer to evenly distribute the formulated liquid. This allows the solution to penetrate the soil evenly, making it less disruptive than mechanical methods.
Several substances are required to prepare the liquid for the aeration. Some of these substances include ; surfactants, humic substances, enzymes and nutrients etc.

1. SURFACTANTS (WETTING AGENTS): It reduces the soil water surface tension, allowing for deeper penetration into the soil instead of pooling or running off and it is more efficient nutrient uptake. The results of using liquid aeration are often visible within a few weeks, with grass becoming greener, thicker, and more resilient against external stresses such as drought or high foot traffic.

2. ENZYMES: Enriched organic matter that improves soil structure, feeds microbes, and helps break down thatch. It breaks down the organic matter, and the nutrients support overall plant growth.

3. YUCCA EXTRACT: It serves as a wetting agent. Its purpose is to help the mixture coat the grass all the way down to the roots.

4. HUMATES, COMPOST, AND SEAWEED: These materials contain vital nutrients and enzymes that enrich the lawn and help decompose the thatch layer. It retains the nutrients and assist in microbial activities.

MICRO-CHANNEL CREATION: The solution loosens tightly packed soil particles, creating tiny pathways for air, water, and nutrients to reach the root zone

BENEFITS OF LIQUID SOIL AERATION

1. REDUCES COMPACTION: Loosens soil from heavy foot traffic or environmental factors.

2. IMPROVES WATER INFILTRATION: Helps water soak in more effectively, preventing runoff.

3. BOOSTS NUTRIENT UPTAKE: Better air and water flow means roots can absorb more nutrients.

4. LESS INVASIVE: No need for noisy machinery or plugging the lawn. 

SOIL COMPACTION
Soil compaction occur when soil particles are compressed together, hindering water and air movement. This can occur due to poor soil management practices, heavy machinery usage, foot traffic or grazing animal foot.
Compacted soils negatively affect plant growth, making liquid soil aeration a helpful solution in tackling soil issues.

DIFFERENCES BETWEEN LIQUID AERATION AND CORE AERATION

1. APPLICATION OF BOTH LIQUID AERATION AND CORE AERATION
Core aeration is mechanical (hollow tines remove soil plugs using machines). Liquid aeration uses a chemical spray and organic liquid additives.

2. TIME OF ACTION: Core aeration offers immediate results . While liquid aeration provide a long-term soil improvement (like a week). 

3. DISTRUCTIVE ABILITY: Core aeration causes disruption to soil structure while liquid aeration has minimal disruptive effect.

4. PERIOD OF APPLICATION: For maintaining a green and healthy lawn through out the summer period, liquid aeration is far superior. While during winter period, core aeration is the best.

5. Liquid aeration is an important part of Lawn Science’s organic lawn care system. While core aeration is a mechanically or manual based lawn care system.

6. Core aeration has been the go-to way of aerating for many years, but liquid aeration has proven more advantageous as a new-school method.

7. Core aeration, sometimes called manual aeration, is performed by a spike aerator or a plug aerator. With its purpose is to create holes in the soil and break up thatch.
Plug aerators are generally more effective, but they produce unsightly cores of dirt that sit on the lawn. It can take weeks for these cores to break down, and many find that these soil cores resemble goose droppings. While on the other hand, liquid aeration is effective without the need to bore holes in the lawn. With this method, an organic mix of chemicals is applied to the grass. It gets to work, breaking down the thatch layer and allowing the grass’s roots to breathe.

8. SOIL COVERAGE
Because traditional aeration methods create individual punctures or plugs in the soil, they may not provide even treatment coverage. However, liquid aeration covers the entire lawn surface uniformly

9. SURFACE DISRUPTION
Core aeration leaves behind visible soil plugs that take time to break down, while liquid aeration is far less disruptive, leaving no unsightly residues on the lawn.

10. OVERSEEDING COMPATIBILITY
Core aeration is ideal for those wanting to also overseed. Liquid aeration is not highly recommended in combination with new seeds. 

11. LONG-TERM IMPACT
Core aeration is generally performed once or twice a year, while liquid aeration can be applied more frequently to address ongoing compaction issues and build soil health over time. 

12. COST AND TIME: In terms of cost and time, liquid aeration is generally quicker to apply than core aeration. It requires less equipment and labour, making it a practical choice for farmers.
However, multiple application may be needed to achieve a desired result which can increase cost over time.

With these differences, Liquid aerators had proven to be superior to core aeration. Its effects last longer, and it doesn’t leave behind ugly cores on the lawn. However, that doesn’t mean that manual aeration methods do not have their place. In some instances, it may be beneficial to use both methods at the same time.

SIGNS THAT A LAWN NEEDS AERATION

Lawns can be aerated once-per-year. Aside from checking the calendar, there are a few other signs that reveals that a lawn needs aeration.

1. THE SIMPLE POPULAR SCREWDRIVER TEST: This is a type of test used to determine if the lawn needs aeration or not. This is done by simply taking a screwdriver and sticking it into the soil. If it is difficult to drive the screwdriver in, that means the soil is too compacted for grass to grow properly.

2. PUDDLES FORMATION AFTER A RAIN DROP: This is another simple and easy way to determine if a lawn needs to be aerated or not. After a rainstorm, if puddles collect on the lawns and the soil cannot soak up this water, that means the soil cannot supply water to the grass roots.

3. SYMPTOMS OF POOR GROWTH: When grasses show signs of poor growth or looks unhealthy, it could require aeration. There are a number of things that can contribute to unhealthy grass, but aeration is often the remedy. This is especially true if the yard has not been aerated in a year or more.
Unhealthy grass can take on many forms. It could be patchy and thinning in certain areas, could change colour from green to a shade of yellow or brown, or stop growing entirely.

4. THATCH BECOMING VISIBLE: In some cases, the layer of thatch may actually be visible. This is a sign the soil need to be aerated. Aeration is the only way to break up this overgrown thatch layer.

OPERATING PRINCIPLES OF LIQUID AERATION

Lawn Science’s liquid aeration efforts are an organic lawn care method. The mix of compost, humates, yucca extract, and seaweed is all-natural and completely safe.
The liquid aeration formula is sprayed directly onto the lawn. Without boring any holes, it can remove the layer of thatch. It also introduces much-needed nutrients to the lawn.
The liqud mixture starts working as soon as it is applied to the grass, but it may take a month or more to see its effects in action. If the layer of thatch is thick or if the soil is especially compacted, the lawn may need more than one treatment.

THE BENEFITS OF LIQUID AERATION

Maintaining a vibrant evergreen lawn goes beyond regular watering and mowing. It requires a deep understanding and application of expert lawn care techniques, one of which is liquid aeration. This process is vital in achieving not only an aesthetically pleasing landscape but also one that is healthy and resilient.
While manual aeration can be a valuable practice for lawn management, there is no doubt that liquid aeration is the better option. It offers many distinct advantages over manual aeration.
Some of its benefits include;

1. EFFECTS LAST LONGER
Liquid aeration is an ideal lawn care treatment for those who want the beauty of their lawn to stand the test of time. Its effects can last for months.
On the other hand, the benefits of manual aeration are often short-lived. The thatch layer comes back in a hurry, leaving the lawn desperate for water and air.
This can have a catastrophic impact on the health of the lawn. It will not be able to resist the summer heat or drought conditions. It can also become discoloured, leaving a brownish lawn while the neighbor’s grass is still wonderfully green.

2. NO CORES LEFT BEHIND:
To many, the cores left behind from core aeration methods are an eyesore. They dot a landscaping effort that lawn service manager work tirelessly to maintain.
No one likes seeing these on their lawn. They make it difficult to enjoy spending time in the grass and can hamper a home’s general appearance.
Fortunately, liquid aeration does not require digging cores or disturbing the soil. The aeration mixture leaves behind no evidence of the aeration efforts, aside from a healthy lawn.

3. MUCH EASIER TO APPLY:
Traditional aeration methods take time to apply and can be back-breaking work. It can take hours for lawn care professionals to manually aerate a medium-sized lawn, even with professional-grade equipment.
On the other hand, liquid aeration can be done quickly. In this instance, saving time also saves money. The lawn care technician can apply the liquid aeration with ease, leaving the solution to get to work.

4. COVERS A WIDER SURFACE AREA:
During manual aeration, the technician may need to make multiple passes over the same area of grass with their aeration machine. This makes the job even more difficult and takes even more time.
However, thanks to the ease of application, liquid aerating a larger lawn is no issue. The technician will easily be able to cover even the largest lawns with the liquid aeration solution.

5. REACHES MUCH DEEPER SOIL HORIZON: Manual aeration methods can only penetrate about three inches deep into the soil. While this is good enough to see some results, liquid aeration can reach much deeper horizons. With liquid aeration, the solution can reach around a foot below the surface. This is especially beneficial, as it ensures that water and nutrients can reach the deepest roots.

6. AN ECO-FRIENDLY SOLUTION: The blend of seaweed, compost, yucca, and humates is all-natural and organic. This means that it is safe for the environment and can be applied to a lawn without harming the natural ecosystem.

7. LIQUID AERATION FROM A LOCAL EXPERT
Every lawn can benefit from aeration. It clears away the layer of thatch that prevents a grass’s roots from receiving water and sunlight and helps loosen compacted soil.
Manual aeration and liquid aeration are both common ways to aerate a lawn, but those looking for long-term results with a deep reach should opt for liquid aeration services.

8. PERIOD OF EXISTENCE: Liquid aeration is an innovative method that involves the application of a liquid solution to penetrate the soil, improving its structure by breaking down compacted soil layers and promoting oxygen circulation. This technique enhances root growth, nutrient uptake, and overall soil health. Unlike traditional mechanical aeration, which has being existing over years requires puncturing the soil to create air pockets, liquid aeration offers a less invasive yet highly effective solution to soil compaction problems.

9. Timing is equally important when considering liquid aeration. The effectiveness of this treatment depends significantly on when it is applied. The optimal timing can vary based on climate, grass type, and soil condition. In the upcoming sections, we will delve deeper into the benefits of liquid aeration, how it works, and guide you on the best practices for timing this essential lawn care service to ensure your yard remains in peak condition year-round.

10. ENHANCING SOIL STRUCTURE WITH LIQUID AERATION
Liquid aeration is a groundbreaking technique in lawn care that significantly improves soil structure without the need for mechanical disruption. This method involves applying a specially formulated liquid solution that penetrates deeply into the soil. As it moves through the soil, it fractures compact layers, creating microscopic channels through which air, water, and nutrients can freely move. This process is vital for promoting strong root development and overall plant health.
The surfactant reduces the soil’s surface tension, allowing for deeper penetration and more efficient nutrient uptake. The results of using liquid aeration are often visible within a few weeks, with grass becoming greener, thicker, and more resilient against external stresses such as drought or high foot traffic.

11. IMPROVING AIR AND NUTRIENT PENETRATION
Compacted soil can suffocate the roots of your grass, preventing essential air and water from circulating properly. This can lead to numerous lawn problems, including weak growth, patchiness, and increased susceptibility to diseases. Liquid aeration addresses this issue directly by loosening the soil, thus improving airflow and making it easier for roots to absorb nutrients.
By enhancing the soil’s porosity, liquid aeration ensures that fertilizers and water reach the root zone more effectively. This increased efficiency not only supports healthier grass growth but also contributes to the overall sustainability of your lawn care regimen by reducing the need for excessive watering and fertilization.

11. OPTIMAL TIMING FOR LIQUID AERATION
The timing of liquid aeration is crucial for achieving the best results. Generally, the best times to perform liquid aeration are during the growing seasons of spring and fall. This timing allows grass to heal and fill in any open areas after the soil improves, which is especially important in active growth phases.
In spring, applying liquid aeration can help wake up your lawn from dormancy by encouraging deeper root growth and preparing it for the vigorous growing months ahead. In fall, it helps strengthen the roots in preparation for the colder months, ensuring that your lawn remains healthy and robust throughout the winter.
Avoid applying liquid aeration during the hot summer months or when the lawn is dormant in winter, as extreme weather conditions can hinder the effectiveness of the treatment and the recovery process of the grass.

12. LONG-TERM BENEFITS OF REGULAR LIQUID AERATION
Implementing liquid aeration as a regular part of your lawn care routine can have several long-term benefits. Firstly, it gradually alters the soil structure to become more resilient against compaction. With ongoing applications, your lawn can maintain optimal conditions for air and water movement, which are crucial for sustaining healthy grass.
Additionally, lawns that undergo regular liquid aeration tend to have better drought tolerance. The improved soil structure allows for deeper water penetration and retention, which means that during dry periods, your grass has access to moisture that would otherwise not be available in compacted soil. Furthermore, by fostering a healthy root system, liquid aeration decreases the need for chemical treatments. Healthy lawns are less prone to pests and diseases, reducing the necessity for pest control and fungicides.
Through frequent application of liquid aeration, especially in the advisable periods of spring and fall, your lawn can continuously operate at its best. Over time, this not only enhances the visual appeal of your yard but also contributes to a more sustainable and ecologically balanced lawn care practice.

13. ENHANCING THE EFFICIENCY OF WATER USAGE
One of the key advantages of liquid aeration is its ability to improve the efficiency of water usage. By creating a more porous soil structure, water can infiltrate the soil more deeply and reach the root zone where it’s most needed, rather than pooling on the surface or running off. This increased water penetration helps to ensure that water, which is a vital resource for a healthy lawn, is used more effectively.
During periods of drought or limited rainfall, a lawn that has undergone liquid aeration can better retain moisture, reducing the frequency and amount of watering needed. This not only conserves water—a crucial consideration in many regions—but also saves homeowners on water bills and contributes to a more environmentally sustainable gardening practice.

14. REDUCING SOIL COMPACTION AND ITS CONSEQUENCES
Soil compaction is a common issue that can severely restrict the growth of grass by impeding the flow of air, water, and nutrients to the roots. Various factors, including heavy foot traffic and the regular use of lawn equipment, can cause this compression. When the soil is compacted, roots struggle to expand, water drainage is poor, and air has less room to circulate, leading to unhealthy lawn conditions like yellowing leaves and stunted growth.
Liquid aeration combats soil compaction effectively by breaking up the compacted layers with a penetrating liquid solution. This method is particularly beneficial because it reaches deeper into the soil than mechanical aeration, addressing compaction at its core. With regular application, liquid aeration can transform a dense, compact lawn into a loose, breathable environment where grass can grow lush and strong.

15. SUPPORTING ECO-FRIENDLY LAWN CARE PRACTICES
By enhancing the natural structure and health of the lawn, liquid aeration lays the foundation for more eco-friendly gardening practices. Healthier lawns are less dependent on chemical treatments because they are better equipped to fight off pests and diseases naturally. This means fewer pesticides and herbicides are necessary, which is better for the environment and the local ecosystem.
Moreover, as soil health improves, the biodiversity beneath the surface flourishes as well. Earthworms and beneficial microbes, which play an essential role in nutrient cycling and organic matter decomposition, thrive in well-aerated soils. Their increased activity helps naturally aerate the soil and enhance its fertility, creating a positive feedback loop that sustains the health of the lawn.

16. Minimal disturbance of the soil (no mess or plugs) 

17. Lowers the chance of utility line and sprinkler damage 

18. It promote beneficial soil microorganisms that aid nutrient cycling and decomposition. Thus, contributing to a balanced soil ecosystem that support plants growth.

APPLICATION OF LIQUID AERATION

For optimal results, liquid aeration should be applied during the cooler times of the day, such as in the early morning or late evening. This timing helps reduce the evaporation rate of the liquid solution, ensuring it has time to penetrate deeply into the soil. It is also crucial to consider the weather conditions before application. Ideally, the lawn should be dry, and no rain should be forecasted for at least 24 hours after treatment to prevent wash-off.
The frequency of its applications depends on several factors, including the type of soil, the level of usage the lawn receives, and the specific grass species. Generally, for most residential lawns, applying liquid aeration twice a year—once in the spring and once in the fall—is sufficient to maintain good soil health and ensure robust grass growth ( as stated above).

For those who prefer a guided approach or are unsure about the specifics of their soil type and lawn needs, consulting with professional lawn care services is advisable. They can assess the specific conditions of the lawn and provide a tailored liquid aeration schedule that fits the unique requirements of your landscape.

PROFFERING SOLUTIONS TO DIFFERENT SOIL TYPES

Different types of soil respond distinctively to liquid aeration. Clay soil, for instance, tends to be heavy and dense, and can greatly benefit from aeration as it helps to create space for air and water to move freely. Sandy soil, while naturally more porous, can also profit from liquid aeration as it helps to bind the soil particles slightly, improving nutrient retention. Loamy soil, being an ideal mix, generally shows the most immediate improvement in terms of root development and moisture retention.

It is important to identify soil type to tailor the aeration process for its specific needs. This customization can enhance the effectiveness of the treatment, promoting superior lawn health and vigour. A soil test can be conducted to obtain accurate information about the soil composition and pH level, which can further guide the customization of the lawn care routines, including fertilization alongside aeration.

ENHANCING GROWTH POST-AERATION

After liquid aeration, checking on the lawn is necessary. The newly created channels in the soil help seeds penetrate the soil more effectively, thereby improving seed-to-soil contact and germination rates. This step is especially effective in the fall when temperatures are cooler and there is ample moisture – conditions that are conducive to seed germination.

Moreover, following up the aeration with light fertilization can be beneficial. Since the soil is less compact and has improved nutrient pathways, the added nutrients from fertilizers can be more readily absorbed by the grass roots. However, it is crucial not to over-fertilize, as excessive nutrients can lead to rapid, weak growth and greater susceptibility to diseases.

TIMING AND WEATHER CONSIDERATIONS

As previously mentioned, the two most effective times to apply liquid aeration are during the spring and fall. These periods represent the peak growing times for most types of grasses, which helps ensure that lawns recover quickly and fully benefit from the treatment. Additionally, ensure that there is no forecast of heavy rain immediately after application to prevent the solution from washing away before it has had time to work into the soil.

Temperature is another crucial factor to consider, as the efficacy of the liquid aeration solution can diminish in temperatures that are either too high or too low. Moderate temperatures between 50°F and 75 °F are ideal for liquid aeration as they ensure the solution remains active and effective from application until it has been fully absorbed into the soil.

REGULAR MAINTENANCE FOR OPTIMAL RESULTS

To maintain the benefits of liquid aeration over time, regular upkeep of the lawn is essential. Consistent mowing, watering, and periodic reapplication of liquid aeration can keep your lawn healthy and prevent the soil from becoming compacted again. Monitoring your lawn’s condition and responding to issues such as brown spots, thinning grass, or signs of pest infestations promptly can help sustain the lush, green appearance of the turf.

Incorporating these aeration practices into a comprehensive lawn care plan will significantly contribute to the long-term health and resilience of the lawn. By maintaining a schedule that includes bi-annual liquid aeration, timely overseeding, appropriate fertilization, and regular monitoring, lawn owners can enjoy a vibrant and robust lawn that enhances the curb appeal of their home and provides a safe, enjoyable space for outdoor activities.

SEASONAL AND REGIONAL CONSIDERATIONS  

For those cool-season grasses (Kentucky bluegrass, fescue, ryegrass), mark your calendar for fall aeration. As temperatures cool, those soil plugs relieve summer compaction, strengthening roots before winter hits, and creating the perfect bed for overseeding. Spring works too if the window is missed, but fall is where the magic happens. This is prime time for lawns across the Northeast and Midwest, where cool-season grasses thrive.

OVERSEEDING AND FERTILIZATION AFTER AERATION  

Patches or other exposed areas in the yard can be covered with overseeding. Maximize the benefits of a seeding application by combining aeration with the increased root growth of autumn and spring can be carried out. 
By creating a fertile bed, aerating the lawn allows new seeds to germinate. Air, nutrients, space, and water all work together to help new seeds grow and cover bare spots. 
Core aeration provides an excellent opportunity to put down fertilizer or seed within 48 hours since the lawn is extra “open” to nutrients during this time. For liquid aeration, there may need to wait a week before using fertilizer. 

TERMINOLOGIES IN SOIL AERATION

1. AIR-FILLED POROSITY (AFP): The percentage of pore space filled with air; higher is better.

2. OXYGEN LEVELS: Higher oxygen concentration in soil pores means better aeration. 

3. THATCH : This is a collection of roots, stems, and other plant matter that amasses near the soil.

In conclusion, soil aeration is vital for soil to function like a living system, supporting healthy roots, beneficial organisms, and efficient water/nutrient cycles. When soil is saturated with water, no air exist in such soil, but when unsaturated, air has ability to flow freely within the pore spaces for optimal plant growth and soil organism survival.

The post LIQUID SOIL AERATION appeared first on Supreme Light.

The word porcupine comes from the Latin porcus meaning ‘pig’ and spina meaning ‘spine. These spines are called ‘ quills ‘. When these two words merge together, they form the word from the Old Italian porcospino, meaning ‘thorn-pig’. The regional American name for the animal is quill-pig.
Porcupines are large rodents with coats of sharp spines, or quills, that protect them against predators. These quills are in abundance and protruded, found all over their body and the head. Some species have quills that extend from the tail as well.
The term porcupine covers two families of animals: the Old World porcupines in the family Hystricidae, and the New World porcupines in the family Erethizontidae. Both families display superficial similar coats of rigid or semi-rigid quills, which are modified hairs composed of keratin, and belong to the infraorder Hystricognathi within the diverse order Rodentia. The two groups are distinct and are not closely related to each other within the infraorder.
Porcupines do give birth to babies. A baby porcupine is known as a porcupette. When born, a porcupette’s quills are soft hair, they harden within few days after birth, forming the sharp quills of adults.
The largest species of porcupine is the third-largest living rodent in the world, after the capybara and beaver.

THE PORCUPINE FAMILIES
A porcupine is any of 29 species of rodents belonging to the families Erethizontidae (genera: Coendou, Erethizon, and Chaetomys) or Hystricidae (genera: Atherurus, Hystrix, and Trichys).
These two families are quite different, and although both belong to the Hystricognathi branch of the vast order Rodentia, but are not closely related. Early studies on the physical characteristics of New World porcupines initially described them as being the most basal (earliest to diverge) group among the hystricognaths, and fossil records point to a common ancestor of Erethizontidae and all other hystricognaths occurring 37.2 to 33.9 million years ago in the early Oligocene.

DESCRIPTION OF THE PORCUPINE
Porcupine or “quill pig” are large rodents and have no relation to pigs. They are the largest and heaviest of all African rodents.

a. THE HEAD : The head is roundish and rather domed, with a blunt muzzle and small eyes and ears.

b. THE LEGS AND FEET: The legs are short and sturdy, and each foot has five toes, all equipped with powerful claws. Their feet have unique soles that are pebbly textured with fleshy knots and long curved claws. Both help the porcupine to grip trees to climb. Their front paws have four claws and a vestigial thumb, and their back paws have five claws.
Porcupine tracks are approximately three inches in length, toe curved in with claw indentations appearing ahead of the pad of the foot.
Porcupines have a distinctive gate, appearing to totter from side to side. Their short legs and chubby bodies keep them low to the ground as they slowly meander.

c. THE QUILLS: Their most recognizable feature is, of course, its quills. Quill length varies on different parts of the body, ranging from 2.5 to 30.5 centimeters (1 to 12 inches). Usually, the quills lie flat against the body, but if danger threatens, they raise and spread them. Thus, use them against any predator.
The quill tips has scales that enable it lodge in the skin like fishhooks and are difficult to pull out. New quills grow in to replace lost ones. Furthermore discussions will be done about the quills.

d. OTHER HAIR
Porcupines do not have quills on their faces, feet or bellies and are instead covered in more traditional and softer fur as well as coarser hairs known as guard hairs. When the porcupine is not tensing their quills, the guard hairs are the more visible covering along their backs. Under their tail, porcupines also have stiff bristles that point backwards. When climbing, these bristles help to prevent slippage.

e. SIZE
Porcupines may weigh from 10 to 30 kilograms (22 to 66 pounds) and about 60 to 93 centimeters in length (23 to 37 inches). The male porcupines growing larger than females. They have a life span of 15 years in the wild and up to 20 years in captivity. Their gestation period is between 90 to 110 days.

f. TEETH
Porcupines have 20 teeth ( four incisors and 16 molars). The incisors are used for cutting and their molars for grinding down plant material. Like most rodents, a porcupine’s front two incisors continue to grow throughout their life allowing for and necessitating extreme use to keep their teeth from overgrowing. Their incisors, like beavers, have a reddish-brown colour from iron oxide in the enamel. The iron in their teeth makes them stronger for gnawing on wood.

f. SOCIAL/ MATING ACTIVITIES

Porcupines mate around October/November. After a seven-month gestation (a long period for a mammal of this size), porcupines will give birth to one (rarely two) young around May/June. Porcupines are born with quills, but they are soft and will harden after a few days.
The porcupettes are fairly mobile at birth and will double their size in the first two weeks. The young will spend 4 to 5 months with mom (a long time for a rodent) while she teaches them about den sites and food before striking out on their own in the fall. Porcupines will not grow to be sexually mature until around the two-year mark. Porcupines often live to be seven or eight in the wild.

CHARACTERISTICS OF THE PORCUPINES
1 Porcuines are very family animals. They are very protective of their space and also recognize their family members.

2. Male porcupines live with only the offspring they born. It is important to keep baby porcupines with their male fathers as they become secured and safe and will prevent them from reacting aggressively.

3. When the female becomes prgnant for another male which is not the male it normally mates with, the offspring she gives birth to will be beaten to death by the new male.
The female produces two litters per year with about two to three babies per litter. Thus, farmers can expect an annual yield of about 200 porcuipines if about 50 porcupines pairs are raised in the farm. This makes the farming a lucrative business especially for meat.

4. Cost of feeding porcupines is lesser to about a quarter of that required to feed other livestock .They eat about 2kg of food per day.

5. Technicallities on breeding: Porcupines get preganant for a period of 90 – 95days. During this time, both the male and female should be separated so that the pregant mother and her baby can devwlop well and the mother give birth easily.

6. Three months after given birth, the the porcupette will be weaned from her mother, and the mother will pair with the male Porcupine. One male can pair with about 3 or 4 females to achieve better reproductive efficiency.

7. Inbreeding should avoided because the genwrations of the inbred porcupines will be suaceptible to diseases, death at birth, have many defects, grow slowly and have poor reproductive ability.
To avoid inbreeding, it is necessary to mark the animals and take information of each brweding processes.

THE TWO TYPES OF PORCUPINE
A. THE OLD WORLD PORCUPINES
The Old World porcupines (Hystricidae) live in Italy, West and South Asia, and most of Africa. They are large, terrestrial, and strictly nocturnal.
This order rodentia is divided into the Parvorder: Phiomorpha and Family: Hystricidae ” of the Old World porcupines”. In this family are the following species of porcupine found all over the world:
-African brush-tailed porcupine (Atherurus africanus)
-African crested porcupine ( Hystrix cristata)
-Asiatic brush-tailed porcupine (Atherurus macrourus)
-Cape porcupine (Hystrix africaeaustralis)
-Indian crested porcupine (Hystrix indicus)
-Malayan porcupine (Hystrix brachyura)
-Sunda porcupine (Hystrix javanica)
-Sumatran porcupine ( Hystrix (Thecurus) sumatrae)
-Thick-spined porcupine [Hystrix (Thecurus) crassispinis]
-Philippine porcupine [ Hystrix (Thecurus) pumilis]
-Long-tailed porcupine, (Trichys fasciculata)

THE NEW WORLD PORCUPINES
New World porcupines (Erethizontidae) are indigenous to North America and northern South America also called Canadian porcupine. They live in wooded areas and can climb trees, where some species spend their entire lives. They are generally smaller than their Old World counterparts and are less strictly nocturnal.
In this rodentia order with Parvorder Caviomorpha and Family Erethizontidae ” The New World porcupines” are the following types of porcupines found in different regions of the world:

-North American porcupine (Erethizon dorsatum)
-Brazilian porcupine ( Coendou prehensilis)
-Bicolored-spined porcupine (Coendou bicolor)
-Andean porcupine ( Coendou quichua)
-Black dwarf (Koopman’s) porcupine ( Coendou nycthemera)
-Rothschild’s porcupine (Coendou rothschildi)
-Santa Marta porcupine ( Coendou sanctemartae)
-Mexican hairy dwarf porcupine (Coendou mexicanus)
-Paraguaian hairy dwarf porcupine (Coendou spinosus)
-Bahia porcupine (Coendou insidiosus)
-Brown hairy dwarf porcupine ( Coendou vestitus)
-Streaked dwarf porcupine (Coendou ichillus)
-Black-tailed hairy dwarf porcupine (Coendou melanurus)
-Roosmalen’s dwarf porcupine (Coendou roosmalenorum)
-Frosted hairy dwarf porcupine (Coendou pruinosus)
-Stump-tailed porcupine (Coendou rufescens)
-Bristle-spined porcupine ( Chaetomys subspinosus )(sometimes considered an echimyid)

Porcupines have a tail of about 20–25 cm (8–10 in) long. They are rounded, large, and slow when moving. Their colouration consists of various shades of brown, grey and white.
Porcupines have various methods to defend themselves from predators, the most prominent being the use of their quills, which advertises their unsuitability for being preyed upon. This strategy is known as aposematism. To some degree, the spiny protection resembles that of the hedgehogs, echidnas, and tenrecs, none of which share any spiny ancestors. All of them and also the old-world and new world porcupines, are products of convergent evolution. The spines of the various groups also vary markedly.

Humans have a varied history with porcupines, with some cultures considering a symbols of self-defense or cautiousness. Porcupines appear in mythology in regions where the animal has economic significance, such as for food or in the production of quillwork textiles.

DIFFERENCES BETWEEN THE OLD WORLD PORCUPINES AND NEW WORLD PORCUPINES

The are 11 Old World porcupines which tend to be fairly large and have spines grouped in clusters.
The two subfamilies of New World porcupines are mostly smaller (although the North American porcupine reaches about 85 centimetres or 33 inches in length and 18 kilograms or 40 pounds), have their quills attached singly rather than grouped in clusters, and are excellent climbers, spending much of their time in trees. The New World porcupines evolved their spines independently (through convergent evolution) and are more closely related to several other families of rodents than they are to the Old World porcupines.
Apart from the above, the quills of the New World porcupines are unique among spined rodents. The spines are stiff with a circular cross section that is small in proportion to their length, which allows them to penetrate further into a potential predator before breaking off near the base. In contrast, the spines of the Old World porcupines are similar to those of other rodents with spiny hair, such as the bristly mouse and short-tailed spiny rat, in that they have a concave cross-section and are shorter and softer, making them break off closer to the tip.

g. DIET
All porcupines are herbivores. Some porcupines like the North American porcupine often climbs trees for food. It eats leaves, herbs, twigs, and green plants such as grasses and clovers. In the winter, it may eat bark.
The African porcupine on the other hand is not a climber, instead, it forages on the ground. It is mostly nocturnal but will sometimes forage for food during the day, eating bark, roots, fruits, berries, acorns, beechnuts and farm crops etc.
They also eat tubers and cultivated root crops such as cassava, potatoes, and carrots. Sometimes, they take carrion back to the burrow to nibble on.

DEFENSE (THE PORCUPINE RETALIATION TOWARDS ENEMY ATTACK)

Defensive behaviour displays in a porcupine depend on sight, scent, and sound. Often, these displays are shown when a porcupine becomes agitated or annoyed. There are four main displays seen in a porcupine: (in order from least to most aggressive)
i. quill erection,
ii. teeth clattering,
iii. odour emission, and
iv. attack.

i. QUILL ERECTION: A porcupine’s colouring, aids in part of its defence mechanisms as most of the predators are nocturnal and colour-blind. A porcupine’s markings are black and white. The dark body and coarse hair of the porcupine are dark brown/black and when quills are raised, present a white strip down its back mimicking the look of a skunk. This, along with the raising of the sharp quills, deters predators.

ii. TEETH CLATTERING: The raising of the quills can be accompanied with clattering of the teeth to warn predators not to approach. The incisors vibrate against each other, the strike zone shifts back, and the cheek teeth clatter. This behaviour is often paired with body shivering, which is used to further display the dangerous quills. The rattling of quills is aided by the hollow quills at the back end of the porcupine.

iii. ODOUR EMISSION: The odour defence mechanism is used when the sight and sound have failed. An unpleasant scent is produced from the skin above the tail in times of stress and is often seen with the quill erection.

iv. ATTACK: If these above mechanisms fail, the porcupine will attack by running sideways or backwards into predators. A porcupine’s tail can also be swung in the direction of the predator, if contact is made, the quills could be impaled into the predator causing injury or death.

The porcupine give warning to their potential enemies using their defense system and then attack. They stamp their feet, click their teeth, and growl or hiss while vibrating specialized quills that produce a characteristic rattle. If an enemy persists, then they run backward until they ram their attacker with their quills. The reverse charge is most effective because the hindquarters are the most heavily armed, and the quills are directed to the rear.

BENEFITS OF PORCUPINE FARMING

1. There are some possible antibiotic properties within the quills, specifically associated with the free fatty acids coating the quills. The antibiotic properties are believed to aid a porcupine that has suffered from self-injury.

2. Porcupines are slow-moving animals. All porcupines are social to some degree, though only Old World porcupines are known to form clans or family units.

3. Porcupine quills are used for guard hair headdress, made by native peoples from Sonora displayed at the Museo de Arte Popular in Mexico City.

4. Porcupines are seldom eaten in Western culture but are eaten often in Southeast Asia, particularly Vietnam, where the prominent use of them as a food source has contributed to declines in porcupine populations. Also, in Africa, they are good source of bush meat.

5. In China, the Chinese porcupine (Hystix brachyura hodgsoni), a subspecies of the Malayan porcupine, was one of several wild animals that was widely farmed for its meat, but a broad ban on the consumption of many wild animals in 2020 led to stoppage of this practice across the country.

6. They are good tourist attraction animals especially in zoos where children find them fascinating and attractive.

7. The quills and guard hairs are used for traditional decorative clothing. For example, their guard hairs are used in the creation of the Native American “porky roach” headdress.

8. The main quills may be dyed and then applied in combination with thread to embellish leather accessories, such as knife sheaths and leather bags.

9. Lakota women would harvest the quills for quillwork by throwing a blanket over a porcupine and retrieving the quills left stuck in the blanket.

10. At the end point of the quill is a barb-like structure which act like anchor, causing increased pain when removing a quill that has pierced the skin. The barbs shape makes the quills effective for penetrating the skin and for remaining in place. Due to this, researchers have designed the hypodermic needles and surgical staples to take the shape of the barb. This design of the needle and staples has cause less damage to the skin when used and removed.

11. Porcupines are sometimes kept as exotic pets. They are also raised in captivity for research purposes and to aid in conservation efforts.

12. The porcupine is seen as a pest in some areas due to their salt-seeking behavior. Porcupines will seek out any source of sodium to replenish their reserves after consuming significant amounts of plant matter, and will resort to gnawing on anything that has residues of sodium on or in it, including those from human perspiration. They may chew on tool handles or salt licks, and bite marks are often found in plywood and rubber tires or hoses due to the sodium salts in adhesives used in their manufacture.

13. Porcupine quills have long been a favorite ornament and good-luck charm in Africa. The hollow rattle quills serve as musical instruments and were once used as containers for gold dust. In addition to being targeted for their quills, they are illegally hunted for their meat.

14. Porcupines are good ecosystem engineers, They shape the plant communities through selective food choices and ground disturbances.

15. They are natural “tree pruners,” dropping branches that can provide habitat for other animals.

16. Birds may use their abandoned dens for nesting. 

17. Porcupines are good tree trimmers or tree pruners.

18. The North American Porcupine (Erethizon dorsatum) as the second largest rodent in Acadia after the beaver is used in Wabanaki art for generations.

19. They are prey for other animals such as bobcats, great horned owls and wolves. Due to their quills, the predator flips the porcupine on its back since its belly has no quills and eat them. Meaning source of food for other wild animals.

20. The porcupine meat has a delicious and healthy taste. Animal meat that is found in many mountain stiffs is indeed processed as satay in the Karanganyar area. But, this time it’s not any satay satay. However, satay is full of benefits.

21. Behind the delicious taste, porcupine satay is believed to be able to treat asthma, impotence, premature ejaculation and various other diseases.

22. Accelerate wound healing: Not only soft and delicious, porcupine meat also contains genes that can accelerate wound healing. The high protein in it will also help speed up cell regeneration.

23. Source of meat intake for people with cholesterol:
Every human being definitely needs meat to meet his nutritional needs. But, sometimes someone cannot eat meat because they suffer from high cholesterol. In conditions like this, porcupine meat is the best solution to meet the nutritional needs of cholesterol sufferers. This is because this spiny animal meat does not have cholesterol or non-koleseterol.

24. Treating Asthma:
Liver porcupine is believed to be able to treat asthma and other respiratory diseases. If it is burnt out of oil, the porcupine liver is believed to be able to cure respiratory disease regularly. This is because the porcupine liver contains kitotefin, a compound that prevents smooth muscles in the airways from contracting so that the airways become wider.
Kitotefin compounds will work better if taken with omega 3 and omega 9. In fact, omega 3 and omega 9 are also contained in porcupine meat so the benefits of porcupine meat to treat asthma are no doubt.

25. Strengthen the immune system: Besides being able to treat asthma, kitotefin compounds can also stimulate anti-body formation. Therefore, consuming bermoncong animal meat can also strengthen the immune system.

26. Increase male vitality:
For those people who have vitality problems, porcupine meat in the tail may be an effective alternative treatment. Meat near the hedgehog’s tail is believed to be able to overcome impotence and premature ejaculation.

27. Porcupine tommy is a valuable medicinal material used to soak materials such as wines. This is used to treat tommy pains, stimulation of appetite and digestion.

28. The quills are used for jewelry making

29. The bile is used to treat eye pain, also used as a massage medicine for trumar

30. The meat , the liver and the large intestine are used to treat heat wine diseases

31. Porcupines are source of employment to people. Traders do buy them from hunters and resell to farmers to rear.

32. The meat is protein rich and has a profile similar to that of beef, making it ideal for small dishes like stew.

THE QUILLS
Porcupine may have over 30,000 quills on their body. These quills grow in varying lengths and colours, depending on the animal’s age and species.
These quills comes in varying forms depending on the species, but all are modified hairs coated with thick plates of keratin and are embedded in the skin musculature.
Old World porcupines have quills embedded in clusters, whereas in New World porcupines, the quills appear singly, interspersed with bristles, underfur, and hair. This quills can be used as defence mechanism substances against predators. They release it when an enemy approaches or may drop out when the porcupine shakes its body. As this is done, new quills grow to replace the lost ones. Despite all the myths, assumption and notions in media, porcupines cannot launch their quills at range unless they are annoyed to anger.

THE SUPERPOWERS OF PORCUPINE QUILLS
American porcupines are good tree climbers because they love to feed on the newly developing leaf buds. As they climb to feed on these newly developing leaf buds, they climb to the tender stems of the tree and fall off the tree and land on all their quills. Thus hurting themselves. This is where their superpowers come into play. Each quill is coated with antibiotics that heals the impaled skin. Not only do they heal themselves from these self-inflicted wounds, dog also if impaled will also heal quickly.

HABITAT AND RANGE
Porcupines occupy a small range of habitats in tropical and temperate parts of Asia, Southern Europe, Africa, and North and South America. They live in forests and deserts, rocky outcrops, and hillsides. Some New World porcupines live in trees, but Old World porcupines prefer a rocky environment. Porcupines can be found on rocky areas up to 3,700 m (12,100 ft) high. They are generally nocturnal but are occasionally active during daylight.
They set up their homes in burrows. They burrow this holes beside the plant roots and rocks, or inhabit holes made by other animals, or dig their own hideaways. These burrows are most commonly occupied in family units.
They give birth to between one and four young in the grass-lined burrow. They are well-developed when born with open eyes. The young leave home for the first time at about two weeks of age, as their quills which are soft at birth begin to harden up. They are quite playful and, outside the burrow, they run and chase one another. The young are suckled from six to eight weeks of age and then begin to eat vegetable matter.

PORCUPINE FARMING
Porcupine farming is quit easy compared to pig, poultry and other livestock farming. This farming has not yet being widely established or commonly practiced. These animals are solitary animals that are difficult to manage and breed in captivity. They are naturally nocturnal and have a slow growth rate, with slow maturation and a lifespan of up to 10 years. They are also strictly herbivorous, with their diet consisting of bark, twigs, and other plant matter. Apart from them feeding on plants, they also feed on insects, beetles ,snails, and earthworms which provide essential proteins for their growth. This wide range of food makes them easy to farm and reduce cost of feeding. Farmers also feed them with readily available agricultural by products, vegetable scrapes and corn husks to suppliment their diet.*  
Therefore, to raise a porcupine, an environment that will mimicking all the above mention character in the wild must be adopted on the farm.

CONSIDERATIONS FOR FARMING PORCUPINES

i. SOCIAL BEHAVIOR :  Porcupines are solitary and may fight, so housing them together can be challenging. 

ii. BREEDING: They only breed once a year, with females giving birth to a single offspring after a 7-month gestation period. 

iii. DIET: They are strict herbivores that eat tree bark, twigs, and other plant matter, which could require a significant and specific food source. Refer to the diet above.

iv. NOCTURNAL ACTIVITY:  Being nocturnal, they are most active at night, which might make them difficult to monitor and manage during the day. 

v. SLOW GROWTH: They are slow to mature, reaching adulthood in their second year, and have a long lifespan. 

CLIMATIC CONDITION: Porcupines cannot survive much under cold weather. During winter, especially in the wild, porcupines dig deep holes and stay in it for months. Farmers also need to simulate this by creating holes in their pen and add dry grasses in it to keep them worm.

HOUSING UNIT: Porcupines require a space of about 1m2/porcupine. The enclosure should be designed in a way to balance with light and dark environment.

THE FLOOR: The floor of thw pen should be made of thick concrete and slightly slopy to drain off water and to prevent the animal from digging holes.

THE WALLS: The wall can be made of thich concrete, thick wire mesh or short thin poles. These materials will prevent the porcupines from gaining acess into other porcupine pens to prevent fighting.

REPRODUCTION: Porcupines have a unique aurge for mating. Both male and female are usually kept in separate pen to prevent mating. Thus, to achieve control mating. When the female show signs of heat, the male is introduced into the females pen for mating. Porcupines do reach sexual maturity a year after birth and ready to mate. At this time, they would have reached approximately 10kg by weight.

TEETH GRINDING: Farmers can put bones, woods, mineral blocks and stones in the pen of the porcupines so that they can grind their teeth on them.

HANDLING: Handling porcupine require care because of their sharp quills which can cause sevwre injury. Protective clothings like gloves, shoes and eye wears etc are needed when rearing and processing after killing the animal are required.

PROCESSING AFTER SLAUGHTERING: Once slaughtered, sevwral methods can be used to remove the quills efficiently. These include: Singing over the open flame to weaken the quills, use of a blow touch to loosen them, soaking in hot watet to soften the skin for ease of removal or using specialized tools like pliera or manual removal with hand.

PORCUPINE MYTHS
There are many false myths about these incredible animals. Such include;

Myth 1: They throw their quills at people or animals when threatened. This is not so. People and predators have to come in contact with the porcupine quills to have them stick up in them.

Myth 2: Porcupine quills will fall out on their own if attached. This is not true. Such quills impaled have to be pulled out which is not an easy or painless task. If a person or his/her animal gets impaled, seek help quickly so the quills do not become further embedded.

Apart from these myths, there are certain facts that all porcupine farmers need to know for profitable porcupine farming. When a porcupine has babies, they are called porcupettes. American porcupines usually only have one baby born each year and their quills harden about an hour after birth.
As porcupines are herbivores and are good climbers, they often can be found in trees. How much time they spent in trees is highly dependent on food sources and predators. In places where ground cover is scarce, offering little food and shelter, porcupines will spend more time foraging and sheltering amongst the canopies. They also have an intense craving for salt.
They also like to eat outhouses. This outhouses collect a lot of urine which is loaded with salt.
When threatened, the porcupine will give off a strong odour to warn off predators. If that does not work, they will squeeze the muscles near the skin, making their quills stand out. If the predator gets too close, they will get a face full of porcupine quills.
They are also god swimmers. They achieve this through their quills which are hollow, making them to float on waters.

PREDATORS
Porcupines are slow movers, however, predators certainly have a speed advantage in the retreat strategy. Some of their predators include; Pythons, leopards, large owls, coyote, fox or bobcat, fishers etc.
Climbing trees helps to protect porcupines from these predators. Also, their defensive mechanisms also help out.

CHALLENGES IN WILD AND REARING OF PORCUPINES
i. Human-wildlife conflict threatens porcupines’ existence.
When porcupine populations increases around cultivated areas, they can become serious agricultural pests.
ii. They can be smoked out of their burrows and hunted with spears, nets, or dogs. These practices have eliminated them from densely settled areas.
iii. They are targeted for their quills. These quills have long been a favorite ornament and good-luck charm in Africa and served other purposes as mentioned in the benefits. Thus, causing their illegal hunting and reduction in number in the wild.

SOLUTIONS TO THESE CHALLENGES
Solutions to protecting the porcupine include;

i. Provide education on sustainable growth.
African Wildlife Foundation educates communities about the importance of sustainable practices for agricultural and settlement growth by providing training on best practices and incentivizing conservation agriculture when appropriate.

ii. Set aside land for wildlife.
AWF engages local communities to set aside land for wildlife to live undisturbed. In the Laikipia region of Kenya, which has no formal protected areas, institutions partner with the Koija community and with other private operator to construct the Koija Starbeds Lodge. Koija Starbeds sets aside land for wildlife while, at the same time, creating jobs and income for the local community.

iii. Wild life rangers have intensified efforts in protecting the wild animals from poachers.

iv. Today, farming and rearing porcupines has help relief the load on hunting the animals from the wild and protect them from going extinct.

TERMINOLOGY IN PORCUPINE FARMING

i. PORCUPINE: A large rodent with a coat of sharp spines, or quills, on its back and tail.
ii. QUILL: A modified hair that is sharp, needle-like spine used for defense. They often have microscopic barbs at the tip which cause them to stick and work deeper into a predator’s skin.

Protein is a major food ingredient in livestock feed. Feed without protein in incomplete and not balanced.
This vital ingredient in livestock feed is required for growth, reproduction, and milk production. It is sourced from plant-based feeds like soybean meal, canola meal, and legumes, as well as animal by-products like fishmeal, blood meal and distillers grains. In ruminants like cattle, protein is essential for the gut microbes that help ferment food, while for all livestock, it builds muscle, supports immune function, repair worn cells and aids in overall health.
As of today, insects are reseached upon as vital source of protein not only for livestock feed production but also as human food and manure production. Such insects reported as source of protein include; Ricket, mealworm beetles, black soldier fly etc. Some of them have being discussed and posted under supremelights.org website.

THE MEALWORM
Mealworms also called yellow mealworm or golden grub are the larval form of the yellow mealworm beetle, Tenebrio molitor, a species of darkling beetle. They are not worms but larvae. They are a promising alternative protein source that has brought about a revolution in livestock food, particularly in livestock like monogastric animals such as poultry and pigs. Also, they can be feed to fish and compounded with pet food like parrots etc. They are nutritionally comparable to conventional protein sources like fishmeal and soybean meal, with high protein content, good amino acid profiles, and beneficial fats. Research shows that mealworms can replace a portion of the conventional feed without negatively impacting growth performance, palatability, or nutrient digestibility.

The T. molitor, the darkling beetle is dark brown or black insect in its adult stage. It produces larvae called the mealworm which is up to 1.25 inches (3.2 cm) long and the adults is about 0.75 inches (1.9 cm) long. It is a holometabolic insects, that goes through four life stages:  egg,  larva, pupa, and adult.
These beetles are cuticular in colour (pigmentation of the cuticle) which varies from tan to black. They can thrive anywhere like backyard, farms and even in the space.

SCIENTIFIC CLASSIFICATION OF MEALWORM BEETLE

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Coleoptera
Suborder: Polyphaga
Infraorder: Cucujiformia
Family: Tenebrionidae
Genus: Tenebrio
Species: molitor

Binomial name: Tenebrio molitor

BENEFITS OF MEALWORM BEETLES
i. Tenebrio molitor is used in biomedical research.
ii. Mealworms can be a dietary source for animals and humans due to their high protein and fat content, as well as large amounts of fiber.
iii. They are also considered pests, especially in food storage. They infest and degrade the quality of stored grains or grain products.
iv. Mealworms are typically used as a pet food for captive  reptiles,  fish, birds, and some small mammals.
v. They are also provided to wild birds in bird feeders, particularly during the nesting season.
vi. They are usually used as fishing bait.
vii. They are commercially available in bulk and are typically available as products sealled in containers such as  bran or oatmeal food.
viii. Mealworms are edible for humans, and processed into several insect food items available in food retail such as insect burgers.
ix. They are rich in oleic acid, which may decrease low-density lipoprotein (LDL) and increase  high-density lipoprotein (HDL) levels in the blood.
x. Mealworms have historically been consumed in many Asian countries, particularly in Southeast Asia. There, they are commonly found in food markets and sold as street food alongside other edible insects.
xi. Baked or fried mealworms have been marketed as a healthy snack food, since centuries ago.
In May 2017, mealworms were approved as food in Switzerland. In June 2021, dried mealworms were authorized as novel food in the European Union, after the European Food Safety Authority assessed the larvae as safe for human consumption.
xii. Mealworm larvae contain significant nutrient content.  Every 100 grams of raw mealworm larvae contains 206 kilocalories and about 14 to 25 grams of protein.
xiii.  Mealworm larvae contain levels of potassium, copper, sodium, selenium, iron and zinc that rival those of beef.

xiv. Mealworms contain essential linoleic acids. They have a greater vitamin content by weight compared to beef, B12 not included.
xv. Mealworms may be easily reared using available food products such as fresh oats, wheat bran or grain, with sliced potato, carrots, or apple as a moisture source.
xvi. The small amount of space required to raise mealworms has made them relevant for scalable industrialized mass production.
xvii. They are good natural recyclers that breaks wastes down into nutrients. They are capable of degrading plastic waste, cardboards, styrophones and polystyrene. And researches are ongoing on if they can degrade glass waste materials.
xviii. T. molitor can be the host of many different pathogens and parasites, including entomopathogenic  microbes, protozoa, and tapeworms, which can decrease the mealworm beetle’s survival or reproductive success.
ixx. Mealworms do not carry any diseases harmful to humans, although one study indicated that they may act as an asthma sensitizing agent.

Due to these benefits derived from mealworms listed above, farmers now see them attractive for mass rearing, a technique that promotes disease transmission within the colonies. 

DESCRIPTION
The mealworm beetle is a holometabolic insects, that goes through four life stages:  egg,  larva, pupa, and adult. Larvae typically measure about 2.5 centimetres (0.98 in) or more. Adults are generally 1.25 to 1.8 centimetres (0.49 to 0.71 in) in length.
The yellow mealworm beetle prefers a warmer  climate  and higher humidity. These beetles exist as male and female insects, thus, reproduce sexually. The male mealworm beetles release a sex pheromone to attract females to mate . After mating fertilized eggs are laid.
Mealworm beetles do not fly. They mate and they eat. They lay copious amounts of eggs after mating that cannot be seen. The eggs hatch out into tiny worms that cannot be seen with the naked eye. The worms called mealworms grow until they are ready to be fed to the animals. They possess a relatively hard exoskeleton made up of indigestible proteins and chitin. These worms usually shed this skin (exoskeleton) on regular basis, like a snake. As they grow to large sizes, their colour becomes white.

SPECIES OF THE MEALWORM BEETLE
There are several species of the mealworm beetles with varying differences. The yellow mealworm beetle differs from other beetles, due to the linear grooves that are evenly divided and run along the abdomen. The beetle has only four tarsal segments on its hind legs. Most other ground beetles, similar in size to Tenebrio molitor, have five tarsal segments.
In the case of the black mealworm beetle (T. obscurus), variations from the yellow mealworm beetles ranges from its size and their shape. The abdomen of the adult black mealworm beetle is more rounded and ends in a pointed tip, as opposed to the more rectangular and blunt-ended abdomen of the yellow mealworm beetle. The larvae of T. molitor are lighter coloured than those of T. obscurus.

There are other species of mealworm, one of which is the dark mealworm or Tenebrio obscurus, which matures more quickly than the yellow, and adult beetles lay more eggs. The confused flour beetle (Tribolium confusum) is sometimes referred to as a mealworm. The lesser mealworm (Alphitobius diaperinus [Panzer] is also known as the Litter Beetle, Black Bug or Darkling Beetle. “Superworms” (also called King Mealworms, megaworms, kingworms. Sometimes called Giant mealworms, although these are usually T. molitor treated with growth hormones) are Zophobas morio (sometimes listed as Zoophorbas). They are not treated with hormones, but are naturally larger (around 2-3 times bigger) than regular mealworms. They are native to Central/South America.

DISTRIBUTION

Mealworm bettle most-likely originated from the  Mediterranean region. As at today, they have spread to many areas of the world as a result of human trade and colonization. They have spread  Europe, USA, Asian countries, Africa, Australia and other continent of the world.

LIFE CYCLE

The mealworm beetle is a holometabolic insects, that goes through four life stages:  egg,  larva, pupa, and adult. They start as thiny eggs that hatches into mealworms and eventually transform into the adult beetles.

Depending on food and temperature, it takes about hundred to several hundred days for them to complete their life cycle.

THE EGG STAGE: The eggs are laid by the female mealworm beetle. The incubation and hatching occur between 4-19 days after the female oviposits. Some sources say 20-40 days. The eggs hatch to give larva.

THE LARVAE STAGE: The eggs hatches to the larval stage at 10th weeks. And they become visible after about a week after hatching of eggs.
They burrow below the surface of the grain and undergo a series of molts (10-20 times, average of 15 times), shedding their exoskeleton (looks like Cornflakes). They typically measure about 2.5 centimetres (0.98 in) or more. They feed on vegetation and dead insects, and molt between each larval stage consecutively, or instar (9 to 20 instars as stated above).
The larvae incubate for a period of seven to eight days and a period of three to four days for the first instar. After the first instar, there is significant variation for the number of days in each instar period, though variation may be due to malnutrition or pathogens. Before emergence, most larvae typically go through 15 to 17 instars, with very few larvae going through the 19 to 20 instars. At the first instar, the newly molted larvae are whitish in colour, their exoskeleton has not hardened so they may be more digestible and gradually turn brown after the second instar.
With each successive instar, the body length of the larvae gradually increases , reaching maximum length of 0.98-1.38 inches , with about 200 to an ounce at the 17th instar. The body length decreases beyond the 17th instar. This last molt (instar) occurs about three months after the egg stage.
The fully grown larvae (worms) are golden brown and
The larvae come to the surface. They turn soft and plump, stop moving, curl into a “C” shape, and then transform into naked white pupae that turn yellowish brown after a day. They look sort of like alien grubs.

THE PUPA STAGE:

After the final molt at the larvae stage, they pupate ( that is, pupation occurs after the 14th instar, with most larvae showing total pupation between the 15th and 17th instars) . Pupating is when the larvae changes from worm to beetle. It is a cool and weird stage in darkling beetles. The new pupa is whitish and turns brown over time. They do not eat or move much. If the larvae stock are purchased at fairly large size, this transition may happen in a few weeks.
After 3 to 30 days, depending on environmental conditions such as temperature, the pupae metamorphosize into beetles ( that is, emerges as an adult beetle).
Larvae and pupae generally shared a common nutritional profile: lower contents of crude fiber, crude protein etc.

THE ADULT BEETLE
Adults are generally 1.25 to 1.8 centimetres (0.49 to 0.71 in) in length. They live for about 3 months. This short life span of the beetle gives reason why farmers prefer to leave some worms to pupate, so they can turn into beetles and keep the cycle repeated.
The freshly hatched beetles are quite pale, the colour of the wheat bran, then they turn brown, then finally black.
At first the beetle is white/light beige with a soft shell, and then it darkens and hardens to red, brown, and finally turns dark brown/black after about 2-7 days. The beetle is slightly flat. Males and females are indistinguishable. They can not fly, but they can move very quickly.
Some after hatching do not develop properties like wing cover and look ragged. These ones can quickly be sorted and fed to the poultry birds.
Beetles lay their eggs 9 – 20 days after emergence. They lay for two or three months, and then die. Each female beetle lays about 275 tiny, bean-shaped white eggs – about 40 per day. The eggs are seldom seen because they are sticky and rapidly become coated in substrate.

It is important to note that;

i. offspring produced by older beetles do have shorter larval stages than those produced by younger beetles. Also, larvae from the older beetles do aquire a rapid weight increase at an earlier age than those from young parents.

ii. as parental age increases, the amount of hatched eggs decreases .

iii. from researches, it has been reported that when eggs are laid during the first two months after emergence, approximately 90% of the eggs will hatch. But when the eggs are laid after four months of emergence, only about 50% will hatch.

iv. It has also being reported that larvae from young parents grow at a slower rate, compared to larvae produced by the same parents, nine weeks earlier (old stock). At 30 °C, there were no other effects of parental age on the larvae.

REPRODUCTION

During reproduction, the male Tenebrio molitor  produces and releases a sex pheromone to attract the female beetle. Pheromones are chemical signals that function as mate attractors and relay important information to prospective mates.
In the case of inbreeding, a reduction in the attractiveness occur. This is due to the reduction in the sexual pheromone signaling released by the male mealworm beetles.
The females are more attracted to the odours produced by outbred males than the odours produced by inbred males. The reduction of the male signaling capability may be due to increased expression of homozygous deleterious recessive alleles, caused by inbreeding.
The mealworm beetle breeds are prolific. A female can lay between 70 – 100 eggs at a goal and about 500 eggs per year. The eggs are usually laid in a dark moist place with plenty of available food. The males through their aedeagus insert sperm packets into the females. Within a few days, the female burrows into soft substrates and lays their eggs. They prefer laying in warm and dry area of the substrates. lots of food must be placed on the substrate for them to feed upon and their newly emerged larvae. The larvae, which are creamy brown are initially thiny. They grow to about 1 inch long and start shedding their skin. This is called molten. This shedding is about 10 to 14 times before they form the pupae. The pupae stage can can last to about 6 to 300days depending on the temperature. She had a lifespan of about 6–12 months ( that is, a year).

FOOD FOR THE BEETLES AND WORMS
Farmers can buy some of the food items from an animal feed store or bulk food store. These feed are diverse in numbers. Commonly used food sources include: corn cobs (hiding inside), wheat bran, chaff.
rolled oats (oatmeal – uncooked), oat bran, cornmeal (not cornSTARCH), chick (poultry –fowl or pheasant and turkey) starter/mash ( very nutritious), feces of organisms, eggs, vegetables, fruits, ground dry dog or cat food encourages pupation. It can also be given to worms prior to offering them to birds to increase protein content. Cabbage, raw potato, slice of bread, romaine lettuce, kale (high in calcium), yam (also nutritious), apple slices (1/4 of an apple is enough for 1,000 mealworms, once or twice a week). Note: apples get moldy too quickly. Celery (For example, bottom end of bunch), broccoli stems, carrots (grated carrots on a plastic lid), banana peels, or asparagus chunks. Cabbage leaves ( Cover the cabbage with a cloth to keep it from drying out if a heat lamp is used in the habitate). Leftover low sugar cereal, birdseed (e.g., milo), wheat flour (whole wheat for added nutrition), grain mixture:
(10 parts oat or wheat kernels,
10 parts rolled oats (oatmeal) or whole wheat flour; 1 part wheat germ or powdered milk; and 1 part brewers yeast.
10 parts wheat feed, 10 parts rolled oats, 2 parts brewers yeast rolled oats 10 ounces) etc.
Along side the food materials, supplements can also be added. Such can be mixed with the dry food/bedding. These supplements include; wheat germ, finely ground egg shells or cuttlebone (for calcium), soybean meal, wombaroo insectivore mix, fish flakes, fine mouse cubes, bone meal, graham (whole wheat) flour, and dry brewer’s yeast (provides proteins and trace elements essential to the insects’ growth and makes larvae grow more). Brewer’s yeast can be obtained at health food stores. Sprinkle vegetables/fruit with calcium and vitamin supplements to add nutritional value. Experiments where skim milk (calcium source) was added to wheat bran at the ration 1:3 or 1:2 ratio, yielded better growth than wheat bran alone.

Note:

i. wash/peel the vegetables first before usage to prevent the introduction of pesticides.

ii. Place fruits and vegetables like potato and apple slices side up, even with top of bedding. By putting the skin side down, the bedding/dry food should be prevented from getting too moist.

iii. Use of kiwi skin should have about 15% of fruit still in it (after scooping out the pulp with a spoon and eaten). Mealworms are reported to grow about 3 times fatter and 30% longer in just 2-3 weeks when fed with this fruit and wheat bran used alone as bedding material. The worms also use the kiwi skin as a “cave” as it drys and curls up.

iv. The following materials should be used to serve the food of the beetles and replace the food on it every 2-3 days or weekly;
a little plastic lid, tinfoil pie plate or a piece of cardboard, or stick a toothpick in it. Burlap or newspaper can also be used.
v. Small amounts of moist cat food (like Tender Vittles) can be used. This will provide extra protein for the beetles.

vi. The bedding can be spritz lightly with water on a daily basis. Do not soak, and do not wet bedding. Also a moist (not wringing wet) paper towel can be used and changed on daily basis. A piece of aluminum foil can also be placed under the dampened burlap/paper to prevent the grain from getting wet.

vii. The mealworm larvae can be fed by sprinkling the food into their trays in the case of feeding with grinded or powdery food stuffs.

viii. The feeding frequency depend on the number of larvae but most times, the food os added daily or every 2 to3 days.****

ix. They can eat five times per day. A healthy T. molitor larvae usually prefer diets with a lower protein to carbohydrate ratio, but will shift if there is an infection. For example, bacteria, tapeworm etc infection.

MEALWORM FARMING

Mealworm farming involves raising mealworms in containers with a grain substrate, such as oats or wheat bran, and a moisture source like carrots. The process requires creating a habitat with proper bedding, feeding regularly, and separating the different life stages (larva, pupa, beetle) to continue the breeding cycle.
IMPORTANCE OF FARMING MEALWORMS
Harvested mealworms can be used as

1. a food source for pets or livestock like poultry

2. ground for their frass (excrement), which is a valuable fertilizer.

SETTING UP THE HABITAT
Some of the materials required to set up the habitat include;

i. CONTAINER OR PLASTIC TUBING: The container can be a used plastic bins or tubs or shallow trays with lids that have ventilation holes covered with a screen to keep pests out. The container or plastic tub should be shallow, approximately 6 inches. This height will prevent the worms from climbing the plastic. Other materials like wooden materials etc should not be used as they will easily climb them.

ii. SUBSTRATE: The container should be filled with 2-3 inches of a dry substrate like oats, wheat bran, or cornmeal. Do not overfill, as this can encourage escape. These substrates can serve as their food and also their bedding as they start out. The containers should be placed in a cool dark area because mealworms are naturally nocturnal. Therefore, they prefer low light conditions which help reduce stress and keep them active. The container should always be refilled by putting 2-3 inches of the substrates regularly when the level drops.

Never start by using oatmeal substrates because it may be harder for the microscopic worms to eat the larger oats than the bran.

iii. FOOD AND MOISTURE: The worms should be fed/watered using vegetables. These vegetables are source of moisture for the worms. This should be replaced every few days to prevent mold growth on the fruits. The fruit vegetables like carrot, apple or potato peels and leafy vegetables can be off cut. Enough of them should be placed in the container for the beetles and worms to suck the moisture out of them and eat them.
As the worms grow in size, this will determine the size of the vegetables to place in the container. For example, smaller size worms can be fed with small sized, chopped up vegetable. As the worms grow larger, a whole vegetable can be laid on top of the substrate, the worms will wiggle around it and pull it under.
Other vegetables that can be fed to them include Brassica,Cabbage, lettuce etc, All are very cheap to source for

RAISING THE MEALWORMS
To breed the mealworms, both larvae and adult beetles are needed.
The following factors should be considered when rearing the mealworm;

i. POPULATION DENSITY: Raising the mealworms involve creating a crowded environment with a large number of the beetles. This will help prevent them from getting stuck on their backs.

ii. SEPARATE THE STAGES: After the eggs hatch, separate the larvae from the pupae (the stage before the beetle) into their own bin to allow development into adult beetles.

iii. COLLECTION: Use a three-tier system or sifting to separate the different stages. Mealworms and eggs can be collected for use, while beetles are returned to the breeding bin.

iv. FEEDING: Feed the mealworms regularly, as they need a consistent source of food and moisture.

v. CLIMATIC REQUIREMENT: The yellow mealworm beetle prefers a warmer climate and higher humidity.
a. LIGHT: Consistent with the name darkling beetle, they prefer the dark. Keep the container out of direct sunlight. However, one source indicated that if mealworms develop faster when provided with light. To obtain a supply of adult beetles in the fall, the usual hibernation period of the dark mealworm (a different species) can be prevented by exposing the fully grown larvae to continuous light.

b. MOISTURE AND RELATIVE HUMIDITY: Mealworms do require moisture. Too little moisture slows growth and reduces size. Too much can produce mold.If larvae are provided with dry food, they can survive and produce one generation a year. If they are provided moisture, they will undergo six generations per year will be fatter.

Beetles lay more eggs when the relative humidity is higher – ideally 70% (55-80% is good). In one experiment, at a relative humidity (R.H.) of 20%, beetles laid an average of 4 eggs each, but at 65 percent R.H., they laid an average of 102 eggs each.

Adult worms also become more active between 90 – 100% R.H. Keeping the culture moist also prevents cannibalism. More is not better. If you put too much in, or leave it too long, it will get moldy or become a gooey mess.

vi. TURNING UP AND INSPECTION OF WORMS: A regular check-in on the worms should be done every few days.
The worms should not be stirred up more than necessary. This practice brings the poopy bits up and can kill or damage the freshly molted worms and pupae.
In addition, in the case of the beetles, ignore the dead beetles, as they will be eaten by the other beetles.

vii. REPITITION OF THE REARING PROCESS: Every 4-6 weeks, restart the whole rearing process in a new bin ( thay is, move the beetles over). This means starting a new bin each month. For example, with a 6 month grow out, the farmer will have 6 bins on the go – 5 will be for various stages of the worm growth and one as the main beetle bin.
It is important to note that if the beetles run short of food and moisture, they will eat some of their eggs as a moisture and food source. (so keep them well fed). They should be moved every 4 weeks to a fresh bin so as to gives a larger harvest.

TIMETABLE
Due to the length of days required for mealworm beetles to complete their life cycle, farmers need to prepare a time table for their production process. For example, if worms are to be produced in the spring, start the colony in November or December. For each 20 beetles raeared, farmers should get about 350 adult mealworms in 200 days.
When the colony is kept at room temperature (~72°F.), it will take a much longer time for the pupa to convert to the beetle stage.

PURCHASE OF BREEDING STOCK
Do not buy “giant” mealworms for breeding (or feeding), as they may have been treated with an insect growth hormone to discourage them from morphing into beetles, so they will grow larger. If giant mealworms do morph into beetles, they will be sterile.
Instead, visit the local pet store if they have any adult beetles that can be purchased.

HOW TO START A NEW BIN

To move the beetle to a new bin is easy. This can be carried out by delaying the usual addition of the fresh vegetables for a couple of days OR bring in a ringer (brassicas, broccoli, slice of apple or squash). On doing this, the beetles will become hungry and thirsty and on siting their food and water source, they will become extra happy, feed and drink ferociously.
These vegetables should be placed on the wheat bran substrate for about 30 minutes and check. By this time, the beetles would have covered the whole food and water source. The vegetables should then be picked up (the beetles would hold on it), then move it to the new bin. Either put the vegetables in or gently knock the beetles off it into the new bin.
The substrate in the first bin where the beetles where moved should not be discarded but addition of fresh vegetable chunk should be placed into it. This will make some beetles hiding in the substrate to move up and the transfer continues. This can continue for 3-4 days. Do not dig through or sort the bin, all living beetles within the substrate will eventually come to the top and check out new food although a few will still be straggler beetles in the substrate.

THE MEALWORMS

In the case of the mealworms, after the eggs hatch, sort the large worms from the small ones. Place the large mealworms in a shallow plastic sweater container. Prepare the container by:
Cutting the top to make a hole for ventilation purposes. Use a hot glue gum to adhere window screen to it to keep critters and moths out. Add 2-3 inches of bedding/food substrates like wheat bran, or a 3:1 ratio of wheat bran to dried skim milk, or 4 layers -1/4 inches layers of poultry mash (non-medicated)
separated by layers of burlap or newspaper, or 10 parts oat or wheat kernels, 10 parts whole wheat flour, 1 part wheat germ or powdered milk; and 1 part brewers yeast.
For moisture, add a small wedge of cabbage, broccoli or half a potato. Place it on top of a plastic lid or newspaper to keep bedding dry. Replace vegetable at least weekly or if moldy.
Ideally keep the container temperature at around 80°F (room temperature is fine too) and around 70% relative humidity. Use a moistened sponge in a baggie/ open container (open side up above grain) for additional moisture.
Periodically (for example, every 1 to 2 weeks) sift out beetles from bedding that will contain the eggs/tiny worms. (The beetles may eat the eggs.)
Once worms are big enough, sift frass (waste) and bedding out once a month, dispose of in garden or use for compost making or feed to poultry to pick the left over worms.
Wash and dry container, return worms and add new food.

MAINTAINING THE FARM HYGIENE
Some of the management practices required around and in the rearing habitat include;
i. Remove old vegetable matter and other waste periodically to maintain a clean environment.
ii. Humidity: Control humidity to prevent mold growth. If the habitat gets too humid, the oatmeal may grow fungi, which can harm the mealworms.
iii. Frass: The mealworm and beetle waste (frass) can be collected and used as a garden fertilizer.
iv. fecal matter management: Worms poop, is like powdery material that can barely be noticed. As worms in a bin are moved to other bins, there is the possibility of odour build up. These are odour from the mixture of the feces and the substrate. Thus, the substrate- feces mixture can be changed for reuse of the bin.
This waste can be fed to poultry or composted.
v. Always use a clear container so as to see how much frass (waste) has accumulated. The container should be made of plastic and must be shallow . A shoe box size or sweater storage container (Rubbermaid, Sterilite, etc.) will suffice. A pail can also be used.
vi. The container should have a larger surface area so as to improve survival of the beetles or worms by dissipating heat. Too many worms stored in too small a container will overheat and die (e.g., 5,000 worms in a 2 gallon pail=dead worms.) The mealworms should probably be only 3-4″ deep.
vii. The container should be well ventilated and covered. Ventilation prevents mold growth. Darklingbeetles do have wings, but can’t fly. Some commercial farmers do not cover their bins. Such practice exposes the beetles and worms to pests like mice, rats, cockroaches and some spiders. They will eat up the mealworms. Therefore, the container should be kept closed. A tight fitting cover will also keep flour
and grain moths out.
Note: If the container has a plastic cover, drill holes in it. If condensation forms on the inside of the lid, more holes are needed to be made on the cover. After this, a section at the middle of the lid should be cut out and fine window screening material should be glued to the inside of the lid, around the hole. This will sllow proper ventilation. The window screening also serve as a cover for the container.
viii. Temperature: The ideal temperature to maximize growth is 77-81ºF, but~ 72-74ºF is also ideal at the Mealworm stages.
Mealworms beetles do reproduce in temperatures ranging from 65-100 F, but temperatures above 86ºF negatively impact growth and development (inhibiting pupation). The duration of the pupal stage will depend on temperature. It is six days at 91.4ºF, seven days at 80.6ºF, ten days at 75.2ºF and thirteen days at 69.8ºF.
Temperatures below 62ºF may halt reproduction. In cold temperatures the larval stage can last two years. Chilling worms and then re-warming them may significantly delay pupation. Prolonged exposure to temperatures below 40ºF may kill the worms.
ix. Lightening materials can be used to heat up the room where the containers are placed. Fr example, a 500 watt rheostat controlled ceramic reptile heater can be suspended over the container to keep temperatures high enough for the worms and beetles.
If such heating materials are installed, provision must be installed for air flow. Such can be window screen hole in the rearing room. This will prevent drying everything out( that is , the food, substrates and beddings).
x. By placing adult beetles on moist blotting paper overnight may increase egg production.
xi. To increase the relative humidity of the environment where the rearing container is placed, put a moist sponge inside a plastic baggie (open) and lay the baggie on the bedding. Or,
Place a small but tall (so the beetles do not drown) bowl filled with water in the middle of the farm to increase relative humidity. A sponge can be placed in the bowl to increase the moist surface area.
Lots of success has been recorded using this methods.
Also, the bottom of the sponge can be placed in a plastic baggie (to prevent the meal from getting wet and moldy) and stand it upright in the corn or oatmeal. Re-wet the sponge weekly, and wash it when needed.
xii. The more nutritious the food, the more nutritious the mealworms will be. Place the food, substrate and bedding in layer of about 2-3 inches deep. Replenish the food often, as the worms eat a lot. Change the food out about once a month. Feed the beetles too (same stuff).
xiii. The use of fine particles food, substrates and bedding like fine wheat bran, corn meal, and chick starter, make it easier to sift out large mealworms. Larger particles (e.g., rolled oats) with larger worms make it easier to sift out frass, therefore, food wastage should be prevented. Newly hatched worms are so tiny that they will go through a screen with the frass.
ivx. Cloth or newspaper covering: Partial covering of the food surface (about 2/3) with several layers of newspaper, brown grocery store bags, paper towels, or a folded piece of cloth can be done. Leave space between the paper and edges of the container.
Worms will crawl between the newspaper layers to pupate, which makes it easy to collect them.
xv. For the beetles to lay eggs, some farmers place cloth in the container on which the eggs are laid. However, carrying out this practices might make it difficult to get the beetles off the cloth when maintaining the farm. Beetles also do lay eggs directly on the food source. Also, thick, clean, dry hunk of bark can be placed on top of the bedding. The beetles will lay eggs on it.
xvii. SHIFTTING OF BEETLES
The reason for siftting out beetles is because, they may eat the eggs. Shiftting is carried out using a Sifter. The sifter can be made with a 1/8 inches hardware cloth or nylon reinforced screen tacked onto a wooden frame. If a sifter is made to fit in the bottom of the mealworm container, the frass will fall through the sifter, making it easier to clean the container. The fine hardware cloth may be difficult to locate, instead, a wire mesh basket from an office supply store, or use a device like a Double Over-the-Sink Colander with extendable arms can be used.

EFFECT OF MEALWORMS ON RECYCLING AND DEGRADATION OF POLSTYRENE

Polystyrene foam decreases T. molitor fecundity, but the beetle can fully develop using the plastic as its primary source of food, which makes it an interesting alternative to recycle polystyrene.
In 2015, it was discovered that 100 mealworms can degrade polystyrene into usable organic matter at a rate of about 34–39 milligrams per day. Research has reported that no difference occur between mealworms fed only with Styrofoam and the mealworms fed with conventional foods. Microorganisms inside the mealworm’s gut are responsible for these degradation of the polystyrene, proven by reducing the property of degradation when mealworms were given gentamicin.
Two factors can bring about the reduction in the degradation of this polystyrene materials.

i. When the mealworm gut microbes are isolated from their colonies in the mealworm’s gut. These microbes isolation has proven less efficient than those bacteria within the gut.

ii. When the mealworm’s microbiota is disrupted by an antibiotic treatment, it loses its ability to digest polystyrene, suggesting that its associated gut microbes are essential in the digestion process.
Bacterias in the gut of the mealworms which assist in the degradation of polystyrene in in vitro include: bacterium Exiguobacterium firmicutes, which can be isolated from the midgut of mealworms,

HEALTH RISKS

Some evidence suggests that T. molitor may pose a health risk,

i. as humans and animals can consume the eggs and larvae of the beetle with grain-based food. Although they are usually either digested or are excreted with feces, sometimes, they are able to survive and live in the alimentary tract. The first cases of T. molitor larvae in human organs date back to the 19th century, were observed in the gastrointestinal tract of the alimentary canal, including the stomach and intestines.

ii. There were other cases, such as a reported ulcer infestation of T. molitor in an AIDS patient and a concerned urinary canthariasis in a ten year old boy in Iran in 2019, which was the last reported human case of canthariasis caused by T. molitor.

iii. However, there are very few reported cases of live larvae in animals, and there are no reports of gastrointestinal canthariasis in farm animals.

iv. One farmer indicated she experienced severe upper respiratory infections after handling mealworms and was concerned there might be a connection. She then used a mask and gloves when handling them, but eventually decided to abandon farming.

v. Another had what appeared to be an allergic (respiratory) reaction to the farm – possibly the frass (but not to mealworms stored in a refrigerator.)

HARVESTING OF THE WORMS

The mealworm larvae can be harvested and offered to birds or separate them from eggs and beetles and continue the rearing process. The reach harvestable size after 2 to 3 months of hatching. To harvest the mealworms, use a stainless steel siever to collect the worms.
Put a sheet or newspaper or grocery store bag or a plastic lid on top of the colony. The worms will crawl under it in a few hours. Repeat until all worms are harvested out and then replace the bedding.
Another alternative method is to hold back on moisture for a couple of days to keep them thesty. Then put a lettuce leaf, moistened piece of bread, or damp Bounty paper towel or blue paper shop towel (rung out – re-wet and ring out as needed) in the container on top of the bedding. The larva will cover the bread or lettuce. Pick it up and shake them into a container in readiness for processing, feeding to poultry etc.

CLEANING OF HARVEST
Remove dead mealworms or dead beetles and the frass from the harvest. Dead larvae turn black. Dead pupae turn brown and shrivel up. Deformed beetles die early. Other dead beetles stop moving and their antenna crinkle up.
All these can be fed to poultry birds, processed into livestock feed or composted.

FRASS: As the mealworms consume the bran, a fine, dusty or sandy residue will settle out on the bottom. Eventually, shed exoskeletons and waste products (frass) will build up, and a slight ammonia odour may be detected. That means it is time to sift the grain to separate the worms and adult beetles (do not throw out tiny larvae or eggs); wash the container, add new grain, and return the worms to the container. This can be done at- least 3 times a year. If the frass builds up too much, mealworms may turn gray and get black stripes and then die.
The frass (waste) can be used as fertilizer for flowers or vegetables.

Excess mealworms may be found in the frass. They should be separated into a separate container for a bit. Some lettuce/cabbage can be placed on the frass to see if there are any mealworms that can be separated out.

PROCESSING OF MEALWORM
Meal worms can be processed after harvesting in two main ways.

1. Drying

2. Grinding

DRYING
Aftet harvesting, they can be dried using three methods;
a. Freeze roasting
b. Air drying
c. Use od dehydrator
a. Freeze Roasting: This is the technique used to freeze dry mealworms. Roasted mealworms do not require refrigeration, and do last more than a year in storage. This techniques involves getting large number of mealworms.
Put them in two large plastic containers on arrival and put them in the freezer. Once frozen and dead, heat up the grill on the lowest setting. Put the mealworms into a large disposable aluminum roasting pan, after sprinkling some corn meal into the bottom of the pan to prevent them from sticking to the bottom.
Put them on the grill, close the lid, and let them sit there for about 4-5 hours.
Again, put the grill on a very low setting (maybe only one burner on low) and shake them up every so often. They will turn brownish, but once they are cooked, they will not turn black and disgusting if left out in warm weather.
Once cooked, put them back in the freezer and use them as normal. This does not produce any smell.
Do not use a microwave for processing . If cooked indoor in the oven, it gets a little smelly.
b. AIR DRYING: The melworms are air dried with natural air blow or sundried.
c. USE OF DEHYDRATORS: The dehydrator is a machine that removes moisture from the mealworm and keep it dry. It preserves the nutrients and shelf life of the product

DUSTING: Dusting is one of the processing techniques used on the mealworm. The outer part of mealworms can be dusted with powdered mineral or vitamin formulations ( For example, powdered Calcium [Ca2+] or calcium-vitamin combinations) prior to feeding it to the livestock. The larvae or beetles should be put in a baggie, and gently shake them to coat them with the mineral-vitamin powder. Shake off excess before feeding to the animals.

GRINDING: After drying and dusting, they are grinded to powder form which can be as protein suppliments or mixed with pet food etc. Apart from this grinding, they can be mixed and molded into mealworm bars which pets can fewd upon.

PESTS
Small mammals, e.g. mice, hedgehogs, shrews, sugar gliders, moles, voles, marmosets, bats, rats and other insectivores. Scorpions, praying mantis, centipedes, large insectivorous spiders, etc.
Mites: Sometimes a mealworm colony gets infested by grain mites (Acarus sp.) The mites may come from the mealworm supplier, in bran, or litter from
poultry production, and may infest a colony that has been around for a long period of time. Excessive moisture with heat may be a contributor. They are prolific breeders (800 eggs/female) and can withstand temperatures of 0 degrees and still hatch when brought to room temperature. (Another species that can be a problem is the mold mite, Tyrophagus sp.)
The mites are tiny and round, whitish or tan in colour, and have eight legs. They may cling to air holes and look like very fine sawdust. Mites can not fly.
If the colony does become infested, the mites will kill the larvae and adults. Destroy the colony (e.g. by freezing) and start over.
Another pest is the Brown moths (typically Indian Meal Moths, a common pantry pest that infests birdseed and cereal) may be attracted to the mealworm bedding. If they get into the farm, they make a sticky web almost like cotton candy.

PREVENTION AND CONTROL OF MEALWORM PESTS
To prevent mite infestation:

i. It is also recommended that sterilization should be carried out on all bran/grain (by microwaving it or placing it in a subzero freezer for several days) prior to adding it to a colony to prevent mite introduction.

ii. Apart from the above, create a moat by placing the mealworm containers up on legs, and sit the legs inside small glass or plastic jars filled with water or glycerin (to prevent evaporation ). This will also keep ants out.

iii. Use a Vaseline band (a 2 inch wide band on the outside of the container just after washing and drying it) to prevent mites from getting into a worm bed.

iv. To prevent brown moths, some people store farms outdoors during warmer weather. Some put individual containers inside a larger bin with a screen hot-glued to the top.

v. A “pantry-pest” trap using pherhormones can be used to trap adult moths. Microwaving cereals (for example, 2 minutes), or freezing birdseed and cereals will kill moth larvae that may come in the packaged products.

Palm weevil (Rhynchophorus ferrugineus)

The palm weevil Rhynchophorus ferrugineus is one of two species of snout beetle known as the red palm weevil. This red palm weevil can either be Asian palm weevil or sago palm weevil. The adult beetles are relatively large, ranging between 2 and 4 centimetres (1 and 1+1⁄2 inches) long, and are usually rusty red in colour. Apart from this, many colour variants exist and have often been classified as different species ( for example., R. vulneratus). Palm weevil larvae can excavate holes in the trunks of palm trees up to 1 metre (3.3 ft) long, thereby weakening and eventually killing the host plant. As a result, the weevil is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm etc.

Rhynchophorus ferrugineus

SCIENTIFIC CLASSIFICATION
Rhynchophorus ferrugineus belongs to the Phylum: Arthropoda, Class: Insecta and
Order: Coleoptera. Apart from this, other variants of the red weevil include;
Cordyle sexmaculatus Thunberg, Calandra ferruginea Fabricius, Rhynchophorus pascha v. papuanus Kirsch,
Rhynchophorus indostanus Chevrolat, Rhynchophorus signaticollis Chevrolat,
Rhynchophorus pascha v. cinctus Faust, Rhynchophorus ferrugineus v. seminiger and
Rhynchophorus signaticollis v. dimidiatus etc.
The red palm weevil originate from tropical Asia, and has spread to other parts of the world like Africa and Europe, up to the Mediterranean, Malta, Italy (Tuscany, Sicily, Campania, Sardinia, Lazio, Marche, Puglia and Liguria), etc
It is one delicacy found in many tropical countries. They are large beetles, with hard shiny shells. Most types are black but the one found across the Asian continent is dark red with black markings. The weevils life cycle is in about 5 stages. They spend months as larvae and then pupae – like large, fat white worms. They exist as what might be called ‘grubs’.
They do not look very pretty, and they inhabit and infest palm trees like date palms, coconut palms and ornamental etc.

TYPES OF PALM WEEVILS

All palm weevils are  officially classified into  four types. They are edible weevils, found on almost every continent. Their larvae, and to a lesser extent the adult beetles, are deliberately farmed and harvested all over the world. Recently, in Thailand, more industrialized production of the weevils are carried out. But for many centuries till now, native people using tree felling techniques pick up the larvae from the logs.
Some of the edible Palm Weevils include;
AFRICA: Rynchophorus phoenicis
AMERICAS: Rynchophorus palmarum
ASIA: Rhynchophorus ferrugineus Papua
NEW GUINEA: Rhynchophorus bilineatus etc

SPECIES OF PALMS ATTACKED BY RED PALM WEEVILS
All species of red palm weevil have been reported to attack about 19 palm species and it is the worst such pest in the world. They are reported to have attacked coconut in Southeast Asia, in several Middle Eastern countries, they are reported to have attacked date palm. They are also found in Africa and Europe where they are reported to have been imported with infested planting material. In the Mediterranean region, they are reported to have severely damages Phoenix canariensis. They have now infested almost all coconut-growing and date palm (P. dactylifera) -growing countries.
Some other hosts plants attacked by R. ferrugineus
include: Areca catechu, Arenga pinnata, Borassus flabellifer, Brahea armata, B. edulis, Butia capitata, Calamus merrillii, Caryota cumingii, C. maxima, C. urens, Chamaerops humilis, Cocos nucifera, Corypha umbraculifera, C. utan, Elaeis guineensis, Howea forsteriana, Jubaea chilensis, Livistona chinensis, L. decora, Metroxylon sagu, P. sylvestris, Roystonea regia, Sabal palmetto, Trachycarpus fortunei, Washingtonia filifera, and W. robusta.
In the case of date palm, it has been reported that the weevil prefers the ‘Sukkary’ cultivar of date palm.
Host palm species like W. filifera and Chamaerops humilis may be moderately resistant to the red palm weevil.
The red palm weevil usually infests palms younger than twenty years. While the adult causes some damage through feeding, it is the burrowing of the larva into the heart of the palm that can cause the greatest mortality of trees.
The larvae are known in the Vietnamese language as đuông dừa (“coconut beetle-larva”). “Sago worms” reported from other countries (e.g., East Malaysia, New Guinea) refer to different, related species of Rhynchophorus.

LIFE CYCLE AND STAGES OF DEVELOPMENT OF RPW
The life cycle of the red palm weevil start from the eggs laid, which develop to form the larva to the pupal case, then to pupa and the final stage is the adult stage.

A. EGG LAYING STAGE
After fertilization, the adult female can lay between 300 and 500 eggs. The eggs are creamy white, shiny, and oblong, approximately 3 mm long. These eggs are usually laid on new growth, especially in the crown of the palm, at the base of young leaves, or in open lesions on the plant. They also lay in holes they creat while searching for food, or take advantage of the cracks or wounds in a recently cut palm. When the egg hatches, a white, legless larva emerges. The larva feed on the soft fibres and terminal buds, tunneling through the internal tissue of the tree for about a month. The larvae can occasionally grow to a length of 6 to 7 centimetres (2+1⁄2 to 3 inches). At pupation, the larva will leave the tree and form a cocoon built of dry palm fibers in leaf litter at the base of the tree. The total life cycle takes about 3–4 months.

B. OVIPOSITION STAGE
At oviposition, females bend upward and the tarsi are anchored to the tissue with the spines of the third pair of legs to push the ovipositor into the tough palm tissue. After laying, the female protects and secures the eggs with a secretion that rapidly hardens around the eggs. On average, females produce 210 eggs per clutch, most of which hatch over a period of 3 days. The eggs are white, cylindrical, glossy, oval shaped, and measure 1 to 2.5 millimetres (3⁄64 to 3⁄32 in). The back of these eggs possess special ‘gill cover’ structures that provide the developing insect with oxygen.

C. LARVAE STAGE

The neonate larvae are yellow-white in colour, segmented, legless, and have a chitinous head capsule that is darker brown in colour than the rest of the body. They are up to 5 cm in length and causes damage by feeding on the palm’s soft tissues. They have powerful horizontal conical jaws which they use to burrow from the axils of the leaves to the crown, where they feed voraciously. Upon completion of larval development, the larva will emerge from the trunk of the tree, and build a pupal case of fiber extracted from the galleries inside the palm. The larva will then undergo metamorphosis into an adult. The larva will also weave a pupal case at the base of the palm fronds within the frond itself or at the centre of the base of the plant.

D. PUPA STAGE
Develops inside a tough, elongated, cylindrical cocoon made of fibrous strands from the palm. The pupa is red-brown to black and the future adult’s appendages are visible.

E. ADULT STAGE
The pupa develops to form the adult weevil which possesses wing to fly.
The adult red palm weevil prefer to attack palms that are already infested or weakened by other stress factors. They also colonize healthy palms.
They are excellent flier and can travel great distances.

USES AND BENEFITS OF THE RED PALM WEEVIL
i. Larvae of Rhynchophorus ferrugineus are considered a delicacy in Southeast Asian cuisine. In some regions, however, larvae farming is strictly prohibited to prevent the potential devastation of plantation crops. The grubs can be toasted as found in the Asian palm weevil in Laos and eaten.
ii. The larval grub is considered a delicacy in Vietnam. The larvae are usually eaten alive with fish sauce.
iii. The larva can be cooked, toasted, fried and steamed.
iv. They are eaten with sticky rice and salad or cooked with porridge.
v. Palm weevils are excellent low cost sources of essential nutrients.
vi. They have low carbon footprint if farmed as a commercial enterprise.
vii. In Ghana, Palm weevils serve as a traditional meal for natives of most rural societies (especially within the southern sector) but are not farmed for consumption.
viii. Palm weevil farming is a cost-effective enterprise in terms of supplies and labour.
ix. The larvae reaches maturity within three to four months and can be harvested for consumption – very rich in protein.
x. The farming technique is cost effective and environmental friendly as it utilize agricultural waste as a resource and enhance food security.
xi. The mash used in rearing the larvae is rich in nutrients, therefore, used in compost making and can be sold as compost for crop farmers in amending infertile soils.
xii. Farmers do use the hollowed palm logs burrowed by the larvae, after six months, as containers for gardening and growing ornamental plants.
xii. Weevil larvae can be eaten fried, boiled, roasted or even raw. As they’re 10-30% fat, they do not need oil to cook and will caramelise in their own juices, becoming golden-brown and crisp.
xiii. To avoid exploding larvae, it is advised that they are sliced open a bit before cooking. Just like piercing the film in the microwave.
Palm weevil larvae are good source of lipids, proteins, amino acids and minerals.

DESCRIPTION OF RED PALM WEEVILS

The red palm weevil (Rhynchophorus ferrugineus) is a large, reddish-brown beetle with a long snout, reaching up to 4 cm in length. It has a four-stage life cycle. They lay creamy-white eggs which hatch to form the larvae. The larvae are legless, white in colour with a distinct brown- chitinous head and with powerful jaws. They grow to be large, up to 50 mm or more, and are characterized by their segmented, tapering body. These larvae are the damaging stage, feeding inside the palm trunk and creating frass-filled mines. They pupae to form a tough, fibrous cocoon.

BEHAVIOUR AND HABITAT OF THE LARVAE
i. FEEDING: They feed voraciously on the soft tissues of the palm’s meristem or leaf bases.
ii. MOVEMENT: They burrow and move within the trunk and upper parts of the palm tree.
iii. PUPATION: When ready to pupate, the mature larva will exit the palm and construct a cocoon of palm fibers, or it may pupate inside the damaged tissue of the trunk.

THE ADULT
The adult weevil formed after pupation is a major pest of many palm species. Their larvae bore into the trunk and consume the soft tissues, often leading to the palm’s death.
SIZE: Body length typically ranges from 2 to 4 cm, with females slightly larger than males.
APPEARANCE: They are reddish-brown in colour, but there is significant variation in markings, including dark spots or a dark body with a single red stripe.
ROSTRUM: The head has a long, thin snout, or rostrum, which is a characteristic of the weevil.

FARMING THE WEEVILS
Palm weevils can indeed be raised in large numbers fairly easily using old tree trunks and plastic tubs. The farming involves setting up a breeding environment with a special diet, introducing a male and female weevil pair, and allowing them to reproduce in a controlled, cool, and clean space.
The larvae can be harvested after about 30–40 days, when they have reached the desired size. For the rearing of the weevils, outdoor palm logs or indoor transparent breeding boxes filled with a nutrient-rich mixture, like ground palm stalk and a soybean-based feed can be used. 

TYPES OF FARMING RPW
RPW can be farmed using two major methods. The indoor and outdoor farming methods.

A. INDOOR FARMING
For indoor, this is a controlled farming practices, where transparent breeding box are used. The setup involves; provides a controlled, cool, and clean indoor environment.
ADVANTAGES OF INDOOR FARMING
i. Allows for easy monitoring
ii. Prevents external predators, and
iii. Provides a consistently stable environment, leading to higher yields.
DISADVANTAGES OF INDOOR FARMING
i. Requires initial investment in a suitable box and a consistent, cool environment with temperature between 16.7-23.9°C.

FEEDING
Artificial diet: A mix of ground palm stalk, soybean, corn, and other ingredients are used for compounding the diet.
ADVANTAGES OF ARTIFICIAL DIET
i. Consistent and controllable nutrient source, which can be supplemented with vitamins and minerals for optimal development.
DISADVANTAGES OF ARTIFICIAL DIET
May require some experimentation to find the most effective recipe.

HARVESTING IN INDOOR REARING METHOD:
Extract larvae after 30-40 days using sieving or handpicking. This is a predictable and high-yield harvesting schedule. But it is disadvantageous in the sense that it requires careful handling to avoid disturbing eggs or younger larvae. 

OUTDOOR FARMING PRACTICES
For outdoor, this is a traditional farming practices where palm trunks are used. It involves the use of fresh palm logs or trunks as a breeding site. The logs should be placed in a shady, cool area.
ADVANTAGES OF OUTDOOR FARMING PRACTICES
i. It utilizes a natural and readily available material.
ii. More cost-effective setup.
iii. Lower initial cost compared to the indoor method.
DISADVANTAGES OF OUTDOOR FARMING PRACTICES
i. Weevils may be more difficult to locate and control compared to an indoor setup.
ii. Subject to environmental variables like weather and predators, which can affect growth and yield.
iii. Lower yield per trunk compared to an indoor container. 

HARVESTING IN OUTDOOR REARING METHOD
Harvest larvae after 40-45 days by extracting them directly from the trunk.

CONDITIONS FOR SELECTION OF REARING METHODS
If the farmers priority is a high-yield, consistent harvest and have the resources for a controlled environment, indoor farming is the best. But if the farmer needs a lower-cost, more natural method and are willing to accept a more variable yield, outdoor farming is suitable.
Regardless of the method choosen, provision should be made for a diet rich in protein, such as a mix of soybean, corn, and palm. 

PRODUCTION
Starting with just one batch of palm weevil larvae allows farmers to begin farming with minimal financial risk while still generating a profit. The setup costs are low, the maintenance is manageable, and the potential for growth is substantial.

BREAK DOWN OF THE FINANCIAL POTENTIAL OF PALM WEEVIL LARVAE FARMING, STARTING FROM A SINGLE BATCH AND GRADUALLY SCALING UP TO 100 BATCHES.

SCALING UP: STEPS TO GROW FROM 1 TO 100 BATCHES

i. START SMALL: Farmers should begin with 1 batch to learn the basics of palm weevil larvae farming. This low-risk start allows farmers to gain experience without a significant financial commitment.

ii. GRADUAL EXPANSION:  Increase the farming operation to 5 batches. This step-by-step approach helps farmers manage growth while increasing their revenue and profits.

iii. CONTINUED GROWTH: Move to 20 and then 50 batches as a confidence level and expertise grow. At this stage, farmers will have a strong foundation for a profitable business.

iv. FULL-SCALE OPERATION:  Finally, expand to 100 batches. At this level, the farming operation will be generating substantial income, providing opportunities for reinvestment into other agricultural ventures.

REINVESTING PROFITS: EXPANDING INTO OTHER AGRO VENTURES

Once farmers have established a successful palm weevil larvae farming operation, the profits earned can be reinvested into other agricultural fields such as; crop farming, livestock, or agro-processing. The income generated from the palm weevil larvae farm can be the seed capital for further diversification.

PREDATORS, DISEASES, AND PARASITES OF RED PALM WEEVILS
a. PREDATORS
R. ferrugineus is predated upon by Chelisoches morio
DISEASES
R. ferrugineus is infected by a cytoplasmic polyhedrosis virus and Metarhizium pingshaense,
PARASITES
R. ferrugineus is parasitized by Heterorhabditis indicus, Hypoaspis spp., Praecocilenchus ferruginophorus, Scolia erratica, Steinernema carpocapsae, and Steinernema riobravis.

SYMPTOMS OF INFESTATION

The infestation of the pest can result in yellowing and wilting of palms, and eventual death of the affected plant. The crown wilts first, and lower leaves will follow, due to damage to vascular tissue. Major symptoms such as crown loss or leaf wilt are usually only visible long after the palm has become infested. Secondary infections of opportunistic bacteria and fungi may occur within damaged tissues, accelerating decline. By the time these external symptoms are observed, the damage is usually sufficient to kill the tree, and the infestation may have been present for six months or longer. In high-density infestations, sounds of the larvae burrowing and chewing can be heard by placing one’s ear to the trunk of the palm. Recent research has been conducted using electronic listening devices or dogs trained to recognize the scent of weevils or palm decay to detect infestations at low densities earlier in the process.

PREVENTIVE AND CONTROL MEASURES FOR RED PALM WEEVILS

PREVENTIVE MEASURES FOR RED PALM WEEVILS

1. AVOIDING MECHANICAL DAMAGE: As the weevil prefers to lay its eggs in softer tissues, avoiding mechanical damage to plants can help to reduce infestation.

2. TARRING OF WOUNDS: Tarring wounds after pruning a plant of dead or old leaves can reduce the probability of infestation.

3. PROPER DISPOSAL OF PLANT PARTS: The movement of plant material such as husks, dead leaves, or untreated coir from infested to uninfested areas is not recommended.

4. USE OF INTEGRATED PEST MANAGEMENT (IPM ) METHODS: Strategic methods of RPW-IPM system can be employed to control the weevil. The main components of the RPW-IPM measures include:
(i) regular inspection of palms to detect infestations,
(ii) capture of adult weevils using food-baited pheromone traps (both
(i) and (ii) contributing to pest surveillance),
(iii) preventive and curative chemical treatments, and
(iv) removal/eradication of severely infested palms.
These RPW-IPM components are complemented by phytosanitary (quarantine) measures to regulate the
movement of planting material, and by capacity building and extension activities.

5. REMOVAL OF BREEDING SITES: Apart from the above measures, natural breeding sites of the weevils should be removed, particularly in enclosed gardens and fields.

6. AGRONOMIC PRACTICES: Agronomic practices such as field sanitation, palm density, irrigation, and frond and offshoot removal should be carried out.

7. USE OF BIOLOGICAL CONTROL AGENTS: Effective biological control agents like fungi and nematodes can be adopted to control the weevils. These control agents can reach the pest in their hideout.

8. REGULAR PRUNING: Trimming palm trees regularly to prevent the formation of a suitable environment for the weevil.

9. MAINTAIN CLEANLINESS: Removing agricultural waste around palm trees, as they can be a haven for insects.

CONTROL MEASURES FOR RED PALM WEEVILS
i. Setting of traps for attracting and destroying the weevils. Traps containing sex pheromones can attract the weevil and limit its spread.
ii. Hard pruning as a way of fighting
iii. Treatment of the palms : It has being reported that treated phoenix palm recovered after being attacked by the weevils.
Studies show that this insect is attracted by ethyl acetate, 2-methoxy.4.vinylphenol, gamma-nonanoic lactone, 4SSS-ferrugineol, 50H and 4me-9-5Kt.
iv. PERIODIC MONITORING: Conduct periodic examinations of palm trees to detect the presence of the insect in the early stages.
v. USE OF PESTICIDES: Spray recommended insecticides around the bases of the palms and in the affected holes.
vi. Get rid of the infected palm tree correctly to prevent the spread of the insect.

ORGANIC AND CHEMICAL CONTROL OF THE RED PALM WEEVIL

ORGANIC CONTROL OF THE RED PALM WEEVIL
i. Using beneficial nematodes to eliminate weevil larvae.
ii. Using insect pathogenic fungi as a biological control method.

CHEMICAL CONTROL OF THE RED PALM WEEVIL
i. Use appropriate chemical insecticides such as fenitrothion and deltamethrin.
ii. Spray pesticides directly on the affected areas to ensure the elimination of the insect.

CONTROL OF THE WEEVIL IN DATE PALM

The main control method is through the application of a systemic insecticide. Insecticide is usually applied through a funnel about 5 centimetres (2 inches) above the infested area of the trunk. The red palm weevil can be monitored using pheromone lures and alternative forms of control use field sanitation and mass trapping with traps baited with pheromone and plant derived semiochemicals. New alternative technologies using semiochemicals and bioinsecticides are being developed to attract the weevils to a point source and kill them. Another management technique is to drench the base of palm fronds with the entomopathogenic fungus Metarhizium robertsii (syn. M. anisopliae, Entomophthora anisopliae), or Beauveria bassiana. An Italian company claims to have developed a microwave collar that can be used to sterilize individual trees. For early detection, bioacoustic analysis may be implemented by inserting a sensitive microphone into the tree and recording any produced sounds. These sounds are analyzed by digital signal processing and artificial intelligence to decide whether they are generated by palm weevils.
Also, some palms have natural defense against this weevil. The palms are discovered to possess RNA interference (RNAi, a kind of gene silencing) is a defense system in many host-pathogen systems. RNAi shows promise as a breeding target when breeding palm for RPW resistance.

In summary, red palm weevil larvae farming offers a unique opportunity in agriculture. It is affordable, scalable, and highly profitable, making it an ideal starting point for aspiring farmers. It requires low startup costs and gradually, it can result into an integrated commercial farming system.

The post PALM WEEVIL FARMING appeared first on Supreme Light.

Black Soldier Fly ( Hermetia illucens) farming is an innovative agricultural practice in which BSF are bred and their larvae also raised, which are rich in protein and fat.
Black Soldier Fly (BSF) farming sometimes called black soldier ant farming is not just about insects, it’s about turning waste into wealth, cutting costs for farmers, creating new jobs, and building a sustainable future for food and agriculture. Several opportunities lies in rearing Black Soldier Fly. These opportunities in Black Soldier Fly (BSF) farming is huge and growing globally because it solves two major problems at once: waste management and affordable protein production.
In the farming practices, farmers raise the Fly to lay eggs, which hatches to larvae. The larvae are harvested and used as animal feed for poultry, fish, pigs, and even pets. They serve as a sustainable and cheaper alternative to fishmeal and soybeans.

1. ALTERNATIVE PROTEIN SOURCE: Protein is an essential nutrient source in livestock and fish feed. It is required for proper growth and development, egg development, repair of worm out cells and tissues etc. Most of the sources of protein in livestock and fish feed include; Soybeans, blood meal, fishmeal, etc.
BSF, an alternative source of protein, produce eggs which hatch to larvae. This larvae are rich in protein (40–60%) and fat (30–35%), making them a sustainable replacement for other sources of proteins in fish meal and livestock ( For example; poultry, pig, fish, and pet feed) meal.
Rising global demand for sustainable animal feed creates an ever-growing market for BSF products.

2. WASTE-TO-VALUE SOLUTION
Black Soldier Fly farming has the ability to reduce organic waste. It thrives on organic waste like food scraps, market waste, farm byproducts, manure, etc. The larvae especially, are voracious and are highly efficient at converting organic matter into nutrient-rich biomass, making them ideal organism for waste management solutions. Instead of waste being a problem in the environment, it becomes a free raw material to produce valuable feed and fertilizer.
Industrial food waste, and agricultural by-products, which are organic wastes are not only diverted from landfills but also converted to generate valuable resources that can be used as animal feed, fertilizer, or renewable energy sources. Thus, forming a clise loop system. This closed-loop system helps to minimize waste generation and promotes a more circular approach to waste management.

3. MULTIPLE INCOME STREAMS
From one BSF farm, farmers can generate:
BSF larvae/dried meal → animal feed industry
BSF oil → livestock feed, biodiesel, and cosmetic potential
Frass (BSF manure) → organic fertilizer for crops
Chitin & chitosan (from exoskeletons) → biomedical, industrial, and agricultural uses

4. COST SAVINGS FOR FARMERS
Livestock and fish farmers can cut feed costs by 30–60% by substituting part of their feed with BSF larvae, an alternative to protein source. This cut off the price for protein sources needed to compound the feed, Thus, making farming more profitable and sustainable, especially for small-scale farmers.

5. ENVIRONMENTAL AND SOCIAL IMPACT
Reduces greenhouse gas emissions from waste.
Creates green jobs in insect farming, feed processing, and fertilizer production.
Contributes to food security by providing affordable feed ingredients.

6. GLOBAL MARKET GROWTH
The BSF industry is projected to reach billions of dollars globally in the coming years.
Countries in Africa, Asia, and Europe are investing heavily in scaling BSF production.

IMPORTANCE OF BSF
The importance of the Black Soldier Fly (BSF) lies in its role as a sustainable solution for waste management and a source of valuable resources like protein and fertilizer.

1. FAST GROWTH: In less than 2 weeks, they grow from tiny eggs to fat larvae ready for harvest.

2. WASTE MANAGEMENT: BSF larvae are voracious consumers of organic waste. They feed on food production, kitchen waste, farm residues, manure, markets wastes, and restaurants etc, reducing their volume and the risk of landfill. They convert the wastes into protein. They effectively break down this waste, reducing the amount on landfills.

3. COST-EFFECTIVE FEED: Reduces dependency on expensive fish, poultry and other livestock meal.

4. ENVIRONMENT-FRIENDLY: BSF farming helps reduce methane emissions that would otherwise be released from decomposing organic matter in landfills. They also lowers other greenhouse gases that may be emitted compared to traditional feed sources.

5. POULTRY: Increases egg production and faster growth.

6. USES IN ANIMAL FEEDS. For example: apart from improving poultry production mentioned above,
i. FISH (AQUACULTURE): Replaces fishmeal with excellent growth results.
ii. PIGS: Boosts weight gain and digestion.
iii. PETS (dogs, birds, reptiles): Nutritious protein soumanur

7. BY-PRODUCTS LIKE FRASS (Larvae manure): The larvae produce a by-product called “frass,”. This frass are leftover waste after the larvae feed on the wastes. This is an effective organic fertilizer , rich in nutrients. The fertilizer can be used in agriculture to improve soil structure, water retention, and nutrient content.

8. BSF OIL: Extracted from larvae are used in feed formulation.

9. BSF larvae assist in processing and reduce landfill waste to useful products.

10. The larvae assist in decreasing the release of greenhouse gases, and supports the principles of a circular economy.

11. SUSTAINABLE PROTEIN SOURCE: BSF larvae are a rich source of protein and fat, making them a valuable and sustainable alternative to traditional feed ingredients like fish meal and soy for animal feed.

12. ECONOMIC BENEFITS: BSF farming can create new economic opportunities by providing a low-cost, high-quality protein source for farmers and offering a way to turn waste into wealth.

13. RESOURCE EFFICIENCY: The process requires fewer inputs compared to traditional livestock farming and uses waste materials that would otherwise be discarded

14. As a sustainable alternative to traditional feed sources, Black Soldier Fly larvae offer a nutritious, healthy and sustainable option for farmers and animal feed producers looking for eco-friendly options to optimize their animal nutrition programs.

15. AQUACULTURE:
In aquaculture, BSF have an exceptional nutritional profile. Its larvae is rich in protein, essential amino acids, and healthy fats, making it an ideal feed source for fish. Studies on Trout and shrimp have shown that diets supplemented with Black Soldier Fly larvae can enhance fish growth rates, improve feed conversion ratios, and boost overall fish health.

16. PET FOOD:
BSF has being used as a sustainable and nutritious ingredient in pet food formulations. According to recent data, over 43 brands of pet food already include insect protein source. This innovative approach to pet nutrition has addresses both environmental and health benefits to all animal companions. These health benefits include improved digestion, enhanced immune function, healthier skin and coat, and overall vitality.

17. Additionally, Black Soldier Fly-based pet foods are often free from common allergens and fillers, making them suitable for pets with sensitivities or dietary restrictions.

18. POULTRY AND SWINE
BSF protein is also a valuable source of ingredients in poultry and piglet feed. It offers an impressive nutritional composition needed for sustainable production of the feeds. Industrial research has reported that the larvae are rich in essential amino acids, protein, and healthy fats, making them an ideal dietary supplement for poultry and piglets.

19. Black Soldier Fly frass, the nutrient-rich excrement produced by BSF larvae, is rich in nitrogen, phosphorus, potassium, and essential micronutrients.

20. The frass enhances soil health and promotes robust plant growth and soil biodiversity while reducing the environmental impact associated with synthetic fertilizers.

THE BSF LIFE CYCLE

1. EGGS : Laid by adult flies in crevices near waste (takes 4–5 days to hatch).

2. LARVAE : This is the main stage used for animal feed (lasts 14–18 days). Farmers main focus is this larvae stage, as it is the most nutritious part of the cycle needed for its oil and protein content. The black bsf maggots is called prepupal stage,

3. PUPA : The larvae transform into pupae (7–10 days).

4. ADULT FLY :Lives for about 5–8 days, mates, and lays eggs (does not eat, only drinks water). They are bred to produce eggs, which are then collected and placed in appropriate containers for incubation.
The male mate with the female and the female lay the eggs

COMMON REARING METHODOLOGIES

1. BSF rearing methodologies involves different stages, which include; nursery stage and rearing phases, often utilizing tray-to-tray or batch nursery systems.

A. NURSERY STAGE

In the nursery stage, BSF eggs are incubated and hatch into larvae, which are then transferred to rearing trays or containers.

B. REARING PHASE.
The rearing phases can be divided into two subphases.
a. TRAY-TO-TRAY NURSERY SYSTEMS : This involves a continuous transfer of larvae from smaller to larger trays as they grow, allowing for efficient space utilization and management of larval densities.

b. BATCH NURSERY SYSTEMS:
The batch nursery systems involve rearing larvae in larger containers or tanks without transferring between trays. This simplifys the rearing process but requiring careful monitoring of larval development and overcrowding.

Each of these methodologies have their own unique advantages and challenges. Also, the methodology to use by a farmer depends on factors such as space availability, labour efficiency, and optimal larval growth conditions.

BSF BREEDING AND REARING

Black Soldier Fly farming involves two main distinctive parts:
a. The breeding (reproduction) and
b. Rearing/processing.

a. BREEDING: Breeding of BSF focuses on producing a steady supply of healthy larvae using specialized knowledge. This phase requires a deep understanding of biology to optimize the conditions for mating and egg production. Breeders set up a laboratory, maintain colonies, and adjust environmental factors to encourage the production of healthy larvae. Incubated eggs then hatch into larvae, which are fed food waste “formulas” to stimulate growth.

b. THE REARING AND PROCESSING: This part of the farming aims to convert the larvae into valuable products. It is similar to a traditional food chain, mature larvae are harvested and processed into products such as protein, fertilizer, and oil. Rearing focuses on managing the larvae’s environment and feed, ensuring constant growth. Processing involves converting the larvae into a saleable form, mirroring traditional food production principles.

The Breeding relies on techniques and best practices to increase breeding productivity. The correct methods can help improve insect production, keep insect colonies healthy, and produce top-quality insect-based products.
Under the breeding techniques, the following are embarked upon:

COLONY MANAGEMENT: Proper management ensures healthy and productive insect colonies. These management practices includes;
I. Providing housing with conditions that mimick the insects’ natural habitat. Such conditions include; suitable temperature, humidity, and ventilation.
ii. Regular monitoring of the colonies to detect signs of stress, diseases, or overcrowding. These safeguard the insects’ well-being.
These two practices assist in managing the colonies.

Several challenges are faced in the management of the BSF colonies, especially in ensuring a stable egg output for consistent production. Any alteration of the environmental factors can disrupt egg-laying cycles, leading to irregular egg production. Additionally, managing colony hygiene and preventing the buildup of pathogens or pests is essential to sustain a healthy and productive BSF population.

ENVIRONMENTAL CONDITIONS
Farming facilities used for the rearing of BSF must be designed to regulate environmental factors like temperature, humidity, and lighting. All of these factors significantly affect the insect growth and productivity. Monitoring and adjusting these parameters creates optimal conditions for the insects as also found in livestock rearing. Good hygiene in the farming facilities should also be maintained so as to prevent diseases and ensure the quality of insect-based products. In addition, all equipment, housing units, and feeding areas used should be regularly cleaned and disinferied so as to minimize contamination risks.

COLONY HEALTH
Maintaining a healthy and genetic diversity BSF colony is paramount for sustainable insect production. Best practices for colony health include regular monitoring of population dynamics, disease prevention through biosecurity measures, and maintaining optimal environmental conditions. Introducing genetic diversity through periodic introductions of new genetic material or strains helps prevent inbreeding depression and promotes robustness within the colony. Additionally, implementing strict hygiene protocols, providing balanced nutrition, and minimizing stressors such as overcrowding contribute to overall colony health and longevity.

TYPES OF BREEDING
There are three Flexible Breeding Models. The in-house model was preferred to others, especially in the early days of the industry.
a. OUTSOURCED BREEDING
These breeding type requires specialized personnel with expertise in biology, entomology, and genetics.

b. HYBRID BREEDING MODEL
When taking a hybrid in-house and outsourced reproduction approach, farmers can choose to replace a significant part of their breeding with outsourced supply to make their in-house breeding processes more efficient and more standardized, ensuring production contingency.

c. IN-HOUSE BREEDING MODEL
This is a vertical integrated farms that include additional breeding processes in-house. It requires strict control over colony management, environmental control, and colony health. It is a good practice for supplying BSF colonies with periodic genetic boosts from different BSF lines. Such genetic enrichment results in a healthier colony, with improved neonates’ robustness, growth, and stability

REARING THE INSECT IN BLACK SOLDIER FLY FARMING
In recent years, technological advancements have transformed how Black Soldier Fly farms operate, paving the way for improved efficiency, productivity, and scalability. From automation and machinery to digital monitoring and data analysis, these innovations have revolutionized how Black Soldier Fly larvae are produced and harvested.

TYPES OF FACILITIES
BSF rearing can be approached at different scales, ranging from container modules suitable for small-scale farms to large-scale factories. Each approach to BSF rearing scale has its advantages and considerations, depending on factors such as available space, production volume, investment capacity, and market demand.
In BSF rearing, it is important to note that the larvae are brought to the waste rather than transporting the waste to the larvae. This approach minimizes logistical complexities and ensures efficient utilization of organic waste streams. Therefore, these facilities are ideally implemented near waste sources such as food processing plants, agricultural operations, or urban centers to facilitate easy and cost-effective transportation of waste materials to the BSF rearing facilities. This proximity not only lowers transportation costs but also reduces the carbon footprint associated with waste disposal and insect production.
The BSF rearing modules include:

a. CONTAINER MODULES
Container modules are compact systems that can be set up in limited spaces, making them ideal for urban or backyard farming setups. These modules typically consist of trays or containers for rearing BSF larvae. It facilitate the controlling of conditions and efficient management of small batches of the insects.

b. SMALL FARMS
Small farms are slightly larger setups than container modules. It utilizes multiple container modules or dedicated rearing areas to produce BSF larvae in moderate quantities.

c. LARGE FACILITIES
On the other end of the scale, large-scale factories employ sophisticated rearing facilities with automated systems, climate control, and optimized processes to produce BSF larvae on a commercial scale

CONSIDERATIONS DURING REARING

i. TEMPERATURE: Maintain a stable temperature between 27-32°C for optimal larval growth. 

ii. MOISTURE: The relative humidity of between 50-70% must be maintained in the rearing unit and the substrate should be prevented from getting waterlogged. 

iii. SUNLIGHT: Ensure the breeding cage receives natural sunlight for optimal mating and egg production. 

iv. LOCATION: Place the bins in a stable, well-ventilated area protected from rain. The north side of a building is often a good option because it receives less direct sunlight and rain, but this is not always an option.  Choosing the Right Location is crucial for BSF farming. BSF larvae thrive in warm environments,

BLACK SOLDIER FLY FARMING SETUP
Generally, BSF production is carried out in two steps. The first one is carried out in an insectarium/ love cage. This is where both the adult and egg production takes place. While the second is carried out in a cage netting or a container.
Heavy equipment are not needed to set up a BSF farm. A small space with basic housing unit is required.
The materials needed to operate a Black soldier colony include:

i. Love cage/ breeding cage
ii. cracks for laying egg/ wooden planks (eggies).
iii. atractant to invite BSF to lay egg. The attractant are decaying organic matter,
iv. water bowl for BSF drinking
v. short knife to collect eggs
vi. small bowl and moisture food -for hutchery
vii. Rearing bins.

A black soldier fly farming setup involves a breeding cage for adult flies to mate and lay eggs, and separate rearing bins for larvae to grow. The breeding cage requires warmth light, and an attractant like decaying organic matter to encourage egg-laying on a provided surface like wood. Once eggs are harvested, they are transferred to a hatching area and then to rearing bins with food waste where the larvae grow, after which they can be separated for processing or re-breeding.  

a. BREEDING CAGE:
The breeding unit can be a container or cage where adult flies mate and lay eggs. In case of the cage system, It should be constructed using a mosquito mesh net. And the construction can be as follows:
Construct the mesh cage with legs to elevate it. Place the legs in containers of oil to act as an ant trap.  The cage should be in a location that provides natural sunlight and maintains a temperature between 25–30°C  

EGG-LAYING SURFACE: Provide a rough, dark surface like wood inside the cage for the flies to lay eggs. Place a smelly substrate nearby to attract the flies to the egg-laying surface. 

b. LARVAE REARING UNIT: The rearing unit can be plastic bins, trays, or wooden boxes filled with organic waste where eggs hatch and larvae feed.

c. SUBSTRATE (FEED FOR LARVAE): These can be kitchen scraps, animal manure, market waste, agro-waste like cassava peels or maize husks and also industrial wastes.

Other things needed for the success of the BSF farming operations;

a. MOISTURE: Waste should be moist but not waterlogged.

b. SHADE AND VENTILATION: Flies thrive in warm, humid environments (25–30°C).
c. LIGHT: The light is to keep the cage unit warm as this is required by the insects.

HATCHING AREA:
The black soldier flies are bred to produce eggs, which are then collected and placed in appropriate containers for incubation. The male mate with the female and the female lay the eggs. The following steps are followed after collection of the eggs;
-Collect the eggs every few days by gently scraping them off the surface of the wood.
-Place the collected eggs in a container with a mesh bottom to prevent them from touching the moist substrate. 

HATCHING CONTAINERS: Label and store the hatching containers in a warm area.
-The eggs typically hatch in 3 to 4 days. 
REARING BINS: Transfer the newly hatched larvae to larger containers called the rearing bin.
-Start with a moist substrate made from materials like coconut coir or coffee grounds to maintain moisture levels. 

FEEDING THE LARVAE: Feed the larvae a mixture of organic waste, such as kitchen scraps, rice bran, or coffee husks. Ensure the waste is not too thick (no more than 3 inches) to allow for proper processing. 

HARVESTING: Mature larvae can be harvested after 8 to 14 days. They will naturally crawl up and away from their food source, making it easy to separate them using a sieve or a specialized coffee tray mesh. 

STARTING THE BLACK SOLDIER FLY FARMING
The first step in starting a BSF farming is by collecting eggs from wild flies and rearing the larvae until they reach the prepupae stage. The prepupae stage must grow to reac the pupae stage before farmers can harvest and use them

SOURCE OF BSF FOR REARING
BSF can be sourced from the wild or purchase of pupae or larvae from a reputable breeder farm which will develop into adult flies.
i. SOURCING FROM THE WILD
The adult black soldier fly can be sourced from the wild and reared on the farm.
There are several ways of trapping the fies from the wild for rearing. The most simplest method is to attract the BSF.
HOW TO ATTRACT BSF FROM THE WILD
Materials needed: To attract BSF from the wild, the following are needed. Attractant, eggies and buckets or trays.
i. ATTRACTANTS: The attractant is a smelly liquid substance that attract the BSF. Mostly, the attractant can be banana or pineapple or mixture of both. Other fruits can also be used.
ii. EGGIES: This is a wooden media or paper box. The wooden media are arranged in layers with cravities inbetween for the BSF to lay eggs. It is from here that eggs are harvested.
PREPARATION OF THE ATTRACTANT
-Collect a bunch of ripe banana and pineapple
-In the tray or bucket, mash the banana and the pineapple with their peels into the tray or bucket.
-Level both mashed materials at the base of the tray or bucket.
-Prepare the eggies by arranging the short wooden media in layers and with cardboard layed inbetween the wooden planks. Tie both with a rubber band or thiny rope at both ends.
-Allow to ferment for about 2-3 weeks. By this time, the attractant would have produced a foul smell that can attract the fies.
-Place the eggies on top of the attractants in the bucket or tray.

-The bucket or trays should be taken to where there is no direct sunlight, just at a shaddy location. The attractant now the substrate must not get dry.
-Check after 3 weeks and after every 5 days. The BSF would have laid eggs inbetween the eggies. The eggs will begain to hatch by 4-5 days.
-Wait till the larvae are seen dropping into the substrate to feed.
-Remove the bucket or tray to raise the larvae so that they devwlop to give the BSF.
Apart from this, larvae or pupae can be purchased from a reputable breeder and grown to develop into the black soildier flies.
HOW TO COLLECT BLACK SOLDIER FLY EGGS ON THE FARM

The eggies ( that is, short wooden planks arranged above one another and held with a rubber band) are placed at several locations in the insectarium or love gate. Inbetween the layers of the eggies ( that is the cravices), cardboards should be laid. The BS flies lay their eggs inbetween the cravices of the eggies and collected from the love cages at an interval of 2-3 days (to prevent the eggs from hatching while in the love cage) and are placed in hatching containers filled with a high quality food source (the food source for the new hatchlings should be of a higher nutritional value than the food source for the adult.

To collect black soldier fly eggs, prepare a “love cage” with a good attractant and eggies with crevices. After about 2-3 days, carefully scrape the eggs off the surfaces using a cutter or knife, ideally in the early morning or late evening when flies are less active to prevent escapes.

SETTING UP THE LOVE CAGE /INSECTARIUM

-Use a cage or container with an attractant (like fermented fruit or bran) and provide surfaces with cracks or crevices in the cage for the flies to lay their eggs on.

–WAIT FOR THE EGG-LAYING: After the eggs are laid, collect the eggs every 2 to 3 days. Eggs take a few days to hatch, so checking every 2-3 days is optimal to harvest them before they hatch but also, allow some eggs to accumulate for a better yield.

–CHOOSE THE RIGHT TIME: Collect eggs in the morning or late evening when the flies are less active and less likely to escape, as they become more active when it’s warm.
After collection,
MOVE TO A HATCHING CONTAINER: Place the harvested eggs in a hatching container with a high-quality food source, such as a maize blend paste.
HANDLE WITH CARE: After collecting the eggs, move them to a safer place, away from predators. HARVESTING THE EGGS
Black soldier fly eggs are delicate, so handle them with care to avoid damage.
Scrape the eggs using a small knife or cutter. Gently scrape the eggs off the surfaces of the eggies. The eggs can also be found in small gaps, such as those created by rubber bands.

HATCHING THE EGGS
After harvesting of the eggs, place the eggs in a wooden net mesh. The wooden net mesh should be placed on top of a substrate in a container like bowl. The eggs will hatch on the netting and the larvae formed will drop into the substrate to feed.
The larvae produced should then be transfered into a wooden or plastic trays with substrate spread into it. The trays should be about 2-3 feet deep. Above the 2-3 feet depth, the larvae will suffocate and die due to their inability to feed well. The substrate for starter production will depend on the number of the larvae trasported into the tray. The larvae will feed on the substrates for about 2-3days. Then the substrate should be increased by 5kg occationally. The substrate should be spread evenly above the old substrate with the larvae feeding on it.

PREVENTION OF AMMONIA BUILD UP IN THE SUBSTRATE
Organic substrate, if left for too long can result in ammonia build up. To prevent ammonia build up, aerate the substrate frequently per day by lifting the substrate below to the surface so that heat is not produce and ammonia build up.
In large farms, automated machines are used to prevent this, the machine will sieve out the larvae into a new, fresh substate.

CONTINEOUS PRODUCTION

In the insectarium are the BSF. This fies have a short life and dies. This can be noticed are found died on the floor of the insectarium. To prevent total death of the flies that can lead to total collapse of the farm, more pupae can be harvested and placed on the floor of the insectarium to develop into the BSF. At this point, farmers do make mistakes. Placing the pupae in the insectarium can lead to understocking or overstocking. Understocking means putting too little pupae in a large insectarium. While overstocking means putting too much pupae in the insectarium. This can prevent the BSF from having enough space to peach. If there is not enough space to peach, the female flies will peach on the eggies and find it difficult to lay their eggs. Therefore, to provide enough space for peaching, a mosquito net can be hanged in the insectarium at various location for the BSF to peach. It is also important for farmers to take the temperature and humidity of the insectarium . The humidity must not be too low as this may affect the fies. Also note that the flies do not eat but depend on water. Therefore, a bowl of water should be placed in the insectarium . To keep the humidity in moderate condition , the insectarium can be sprayed with water, or soak cotton wool in watwr and place in it or through the water in the bowl. So, measuring equipment for temperature and humidity must be installed. Apart from these, the insectarium must be well lighted both day and night for the flies to continue mating. Dim light can affect their reproduction process.

TECHNOLOGIES USED IN LARGE SCALE PRODUCTION OF BSF
There are several technologies employed in the rearing of BSF on farms. Such technologies include; Automation and Machinery, Digital Monitoring and Data Analysis technology and harvesting and processing equipments.

AUTOMATION AND MACHINERY
Automation has revolutionized BSF farming, thus, improving production processes and reducing labour costs. Modern farms are equipped with technologies such as; automated feeding systems, temperature control mechanisms, and larvae harvesting technology, enabling farmers to maintain optimal growth conditions and maximize yields. This type is used on large scale farming production.

DIGITAL MONITORING AND DATA ANALYSIS TECHNOLOGIES
Digital monitoring and data analysis are essential tools for optimizing Black Soldier Fly farming operations. Technologies like sensors, cameras, and software systems are used by farmers to monitor critical parameters such as temperature, humidity, and larvae growth rates in real-time. This data is then analyzed to identify trends, optimize feeding schedules, and make informed decisions to improve farm productivity.

INNOVATION IN PROCESSING AND HARVESTING
State-of-the-art equipment, such as automated larvae separators, drying machines, and packaging systems, are used for post-harvest processing of thr insect. The technologies guarantee product quality and consistency. These innovations in BSF processing and harvesting techniques are utilized in comparing between wet processing and dry processing methods.

THE ADULT BSF
The adult BSF do not eat but depend on water. They fly about mate and the female lay eggs in the insectarium. They possess special visual receptors and successfully mate when bright light is available.
Clean water must be made available at all time for them because they do not eat but depend on the water.
At some point, they complete their reproductive fuctions, they lay their eggs in the cravices of the eggies. Each flies die after producing about a thousand eggs. The pupae from the larvae develop into another adult fly.

FEEDING THE LARVAE
After hatching of eggs, the larvae are placed in the breeding trays. Inside the trays should be laid with organic matter or substrate. The organic matter can be mixture of materials like banana, corn meals, wheat bran etc. before intoducing the larvae. The larvae are placed on the organic matter.
Other foul smelly foods can also be used. Such foods can be a mixture of veggies like cabbage, poultry intestine, poultry droppings, rotten fish or any kind of wastes.
The larvae in about 14-18days develop to form the pupae.

HARVESTING THE LARVAE

After 14–18 days, larvae reach their largest size (fat, creamy-colored).

Harvest by sieving or using self-harvesting containers where mature larvae crawl out on their own.

The harvested larvae can be:

Fed fresh to animals (fish, poultry, pigs).

Dried and ground into powder (BSF meal).

Pressed for oil (used in animal feed or cosmetics).

METHODS OF PROCESSING BSF
There are two methods of processing BSF for market and consumer use.
a. Wet processing
b. Dry processing
a. WET PROCESSING: This involves using water or steam to separate larvae from their substrate, followed by methods such as boiling, drying, and milling to produce insect meal or oil. This method is efficient in extracting high-quality protein and nutrients but requires significant water usage and energy input.

b. DRY PROCESSING: This method utilizes mechanical separation techniques such as sieving and air-drying to extract larvae and produce insect-based products. The dry processing reduces water consumption and energy costs. It may result in lower nutrient retention and product quality compared to wet processing.
Today, ongoing research and technological advancements are now aimed at optimizing both wet and dry processing methods, balancing efficiency, sustainability, and product quality in BSF processing and harvesting for diverse applications in agriculture, aquaculture, and animal nutrition.

CHALLENGES TO CONSIDER
Some of the challenges encountered during the BSF farming practices include:
-Maintaining a stable breeding colony.
-Controlling pests like ants and rodents.
-Keeping right moisture levels in the substrate.
-Market awareness.

ENVIRONMENTAL IMPACT AND SUSTAINABILITY
Black Soldier Fly farming has impacted the environment positively and contribution to agricultural sustainability. It has assisted farmers in addressing major environmental challenges such as waste management, resource efficiency, and the promotion of circular economy principles.

i. CARBON FOOTPRINT AND RESOURCE EFFICIENCY
Black Soldier Fly farming offers a sustainable alternative to traditional livestock farming practices. It is known for its high carbon footprint and resource-intensive nature. It requirs fewer inputs such as water, land, and feed than conventional livestock production practices. These farming practices is more resource-efficient and environmentally friendly.

ii. CONTRIBUTION TO CIRCULAR ECONOMY
Black Soldier Fly farming contribute to circular economy movement through the utilization of resources in a system called the closed-loop system, where wastes are reused and maximization of efficiency are achieved. The organic waste are converted into body nutrients which are harvested and transformed into animal feed and fertilizer, a sustainable practice.
Black Soldier Fly farms contribute to the circularity of resources, creating a more sustainable and resilient agricultural system.

FUTURE PROSPECTS AND CHALLENGES OF BSF FARMING
As Black Soldier Fly farming continues to gain momentum as a sustainable solution for waste management and protein production, the industry is also faced with opportunities and challenges. Some of the futuristic prospects and potential obstacles facing this farming practices are stated below;

i. OPPORTUNITIES FOR GROWTH IN BLACK SOLDIER FLY FARMING
The growing demand for sustainable protein sources, coupled with increasing awareness of the environmental benefits of Black Soldier Fly farming, presents significant opportunities for growth in the industry. With a market potential in animal feed, aquafeed, and bioenergy sectors,

Black Soldier Fly farming is poised to expand and become a major player in the sustainable protein market. As more farmers and investors recognize the value of Black Soldier Fly larvae as a resource-efficient and environmentally friendly alternative to traditional livestock feed. The industry is expected to experience rapid growth in the coming years.

REGULATORY AND LEGAL CONSIDERATIONS
Despite its promising potential, Black Soldier Fly farming faces regulatory and legal challenges that may impact its scalability and commercialization. As a novel agricultural practice, Black Soldier Fly farming is subject to varying regulations and guidelines in different regions, which can create barriers to market entry and hinder industry growth. Clear and consistent regulatory frameworks, as well as collaboration between stakeholders and policymakers, are essential to facilitate the development of a supportive environment for Black Soldier Fly farming and ensure its compliance with industry standards.

Summary, as black Soldier Fly farming continues to gain ground as alternative animal feed source, it also offers an innovative approach to waste management and sustainable agriculture. The insects are efficient organic waste managers which turns the wastes into nutrient-rich larvae used as livestock feed and at thesame time minimizes methane emissions and waste sent to landfills, thus, offering an appealing, green alternative to traditional methods.

FUTURE APPLICATIONS

The potential of BSF farming is vast, with promising applications in transforming the feed industry into a more sustainable system. As awareness increases, this practice is likely to play a crucial role in the future of sustainable agriculture and productivity.

Pests are a major concern to farmers all over the world. They are one of the major causes of crop loses on the farm and in store. They can destroy crops on the field and even in storage. Their effect can result in reduced yield and market value. They range from microbes such as bacteria, fungi, to nematodes, insects, rodents, birds, larger animals and even to man. Farmers, researchers etc have deviced several means to control these pests. One of which is agrochemical called pesticides used in conventional agriculture. Another natural method is the use of biocontrol.
Compared with conventional chemical methods which involves the use of agrochemicals, biocontrol is considered an alternative method. It is a much safer alternative since it is less likely to harm any non-target pathogens and produce harmful substances that are detrimental to the environment.
Biocontrol, short term for biological control, also called bioprotection is the use of living organisms to manage pests, diseases, or weeds.  It involves employing natural enemies like predators, parasitoids, or pathogens to suppress the populations of unwanted organisms. This method of controlling pests, whether pest animals such as  insects  and  mites,  weeds, or pathogens affecting animals or plants, relies on  predation,  parasitism,  herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. Biocontrol approach offers a sustainable and environmentally friendly alternative to synthetic pesticides. For example, Syrphus hoverfly larva feed on aphids, making them natural biological control agents. A parasitoid wasp (Cotesia congregata) adult with pupal cocoons on its host, a tobacco hornworm (Manduca sexta,), is an example of a hymenopteran biological control agent.

DEFINITIONS OF BIOLOGICAL CONTROL

Biological control is the use of humans or beneficial insects such as predators and parasitoids, or pathogens such as fungi and viruses, to control unwanted insects, weeds, or diseases.
Biocontrol is also defined as a method of pest control using other organisms, natural enemies, pathogens, semiochemicals and natural substances.
It can also be refered to as a method of pest management that utilizes natural enemies to reduce the populations of pests, weeds, or diseases.
Unlike some other methods of control in agriculture, bioprotection often have little to no side effects.

PRINCIPLES OF BIOCONTROL
The fundamental principles of biocontrol involve using living organisms to manage pests, primarily through conservation, augmentation, and classical (importation) methods, with the goal of suppressing pest populations rather than eradicating them. The main elements include identifying and protecting natural enemies, introducing new ones into non-native environments, or releasing large numbers of existing enemies for quick control, while establishing a self-sustaining system to keep pests below damaging thresholds.
These three approaches of biological control are achieved using the following principles;
i. FOCUS ON LIVING AGENTS: Biocontrol relies on living organisms, such as viruses, bacteria, fungi, or insects, to target specific pests.
ii. PEST SUPPRESSION, Not ERADICATION: The primary goal is to keep pest populations below an economic injury level, not to eliminate them entirely, as natural enemies need a food source to survive.
iii. ECOLOGICAL BALANCE: The long-term goal is to establish a self-sustaining system where pest and natural enemy populations naturally fluctuate together.
iv. SPECIFICITY: Biocontrol agents are often highly specific to their target pests, reducing damage to non-target species.
v. INTEGRATION: Biocontrol is a key component of integrated pest management (IPM), which combines various methods for effective and environmentally friendly pest control.

BENEFITS OF BIOCONTROL
Biocontrol offers environmental benefits by reducing chemical use, protecting biodiversity, and improving soil health. It also promotes human health by preventing exposure to harmful residues and is sustainable by minimizing pest resistance and relying on natural processes. It also have several environmental benefits. Some of the benefits are discussed below;

1. REDUCED CHEMICAL POLLUTION:
Natural predators or other biological agents, reduces chemical pollution by  decreasing or eliminating the need for synthetic pesticides which are harmful to the environment and human health.
Instead of chemicals, biocontrol uses living organisms like predators, parasites, and pathogens to manage pest populations, thereby protecting beneficial insects, pollinators, and soil microbes. This result in a significantly decreased in pollution of soil, water, and air.
Also, reduces harmful residues on crops, and fosters a healthier ecosystem, thus, promoting a more sustainable and less polluted environment. 

2. BIODIVERSITY PROTECTION:
Biocontrol protects biodiversity by providing an alternative to broad-spectrum chemical pesticides, which often harm beneficial insects, pollinators, and soil organisms, thereby reducing non-target effects. The alternative biocontrol measures include use of natural predators, parasitoids, and pathogens. Also, practices like conservation biological control can also enhance biodiversity. This preserve natural habitats. Planting of flowering plants and maintaining diverse vegetation can help support populations of natural beneficial insects. These plants provide food sources (nectar, pollen), shelter, and mating sites for the beneficial insects, thus increasing their abundance and impact on pests.

3. IMPROVED SOIL HEALTH:
Biocontrol suppresses disease-causing pathogens, promoting beneficial soil microbes, increasing nutrient availability through siderophore production and nutrient cycling, fostering greater soil biodiversity, and improving water quality by eliminating chemical residues. Thus, improving soil health.
In addition, biocontrol agents, such as bacteria, fungi, or protozoa etc, replace harmful chemical pesticides usage which can destroy soil health.
These natural enemies are environmentally friendly solutions to improving soil fertile and health.

4. REDUCE RELIANCE ON PESTICIDES: Biocontrol is an alternative to use of pesticides. It can significantly decrease the use of synthetic pesticides, which can have negative impacts on human health and the environment.

5. ENVIRONMENTAL SUSTAINABILITY:
Biocontrol promotes environmental sustainability by providing eco-friendly pest and disease management, which reduces the reliance on chemical pesticides. It also preserve biodiversity by protecting non-target organisms, and fosters healthy soil ecosystems. By controlling pests with natural predators, parasites, and microorganisms, biocontrol decreases the exposure of the ecosystem to toxic substances.

6. TARGET SPECIFICITY: Biocontrol agents are often specific to certain pests, minimizing harm to non-target organisms. They achieve this through rigorous host specificity testing which identify natural enemies that attack only the target pest or weed, preventing harm to other species. This testing involves exposing potential biocontrol agents in a controlled environment to the target organism and closely related species to determine if they will feed on or infect the non-target organisms. The process ensures the biocontrol agent only attacks the intended pest, guaranteeing the safety and effectiveness of the biological control program.

7. COST-EFFECTIVENESS: It reduces the reliance on continuous use of expensive chemical treatments and labour, offers long-term control of pests and weeds, restores ecosystem services, and can provide high returns on investment, especially when proven agents are used in suitable climates. In addition, biocontrol can help manage invasive species that degrade ecosystem services (like providing clean water or food). They can restore the economic and social value of natural areas which might require huge investment to regenerate. Thus, leads to a positive return on investment.

8. INTEGRATED PEST MANAGEMENT: Biocontrol can be integrated into a larger pest management strategy called Integrated Pest Management (IPM), which combines different approaches to control pests.

9..BIODIVERSITY PROTECTION: Biocontrol targets specific pests, leaving non-target beneficial organisms like pollinators and predatory insects unharmed, thereby supporting and improving agricultural biodiversity.

10. ENHANCED FOOD SAFETY:
Biocontrol enhances food security by promoting sustainable agricultural practices that lead to higher, more reliable crop yields, reducing losses from pests and diseases, and improving the overall health of the food system and human populations. It lessens the reliance on harmful chemical pesticides which can result in residual effect in the harvested produce.
It can also safeguards environmental quality, supports biodiversity, and creates economic opportunities for farmers through market access to healthier produce.

11. REDUCE HEALTH RISKS: Biocontrol methods have low or no toxicity, posing fewer health risks to humans, pets, and other animals compared to chemical alternatives.

12. SUPPORT FOR NATURAL PROCESSES: Biocontrol introduces and enhance increment in beneficial organisms (like predators, parasites, or pathogens) into the ecosystem so as to regulate pest populations within the ecosystem. This method maintains a natural predator-prey relationships to leverage the interaction between the natural enemies and the pests. Thus, reducing the need for harmful chemical pesticides and preserving the balance and biodiversity within the ecosystems. This brings about a long-term ecological balance and reduces the risk of organisms developing resistance to the control methods.

BENEFITS OF BIOCONTROL OVER CHEMICAL PESTICIDES
Biological control is considered superior to chemical pesticides for several reasons.
i. biocontrol agents are often highly specific to their target pest, meaning they do not harm non-target organisms like pollinators, other beneficial insects, or the crop itself. In contrast, chemical pesticides are broad-spectrum and can kill beneficial species, disrupting the ecosystem.
ii. pests are less likely to develop resistance to a natural predator compared to a chemical.
iii. biocontrol avoids the problem of chemical residue on food products and prevents pollution of soil and water sources, making it an environmentally sustainable approach.
iii. Some of the negative effects of chemical pesticides usage, include; impact on human health, growing pest resistance, and environmental damage. As a result of these, the benefits of using biological control methods have become more evident.

CHARACTERISTICS OF BIOCONTROL

1. SPECIFICITY: Bio-control agents act as “precision tools,” targeting only the specific pest species, unlike broad-spectrum chemicals.

2. SUSTAINABILITY: It integrates natural processes into pest management and without any environmental damage. Thus, promoting sustainable agricultural practices and reducing the overall chemical footprint.

3. RESIDUE-FREE PRODUCE: The use of biological agents leaves short or no pre-harvest intervals, resulting in chemical-residue-free agricultural products.

4. Often relatively inexpensive and can be “permanent” for those biocontrol agents that can survive multiple years and become self-perpetuating.

5. EFFECTIVENESS CAN BE FROM LOW TO HIGH; Can be disrupted by other pest management tactics, especially broad-spectrum pesticides.

6. Suppressive effects and density-dependent; it will have its greatest impact when pest densities are high.

7. Often pest-specific, not broad-spectrum; Often a lag time between buildup of the pest population and buildup of the biocontrol agent; generally not fast-acting.

8. Good tactic to include in a multi-tactic approach (IPM); fits in well with cultural, mechanical, and some chemical controls.

9. Most successes have been in perennial crops (orchards, vineyards), rangeland, and field or forage crops which can withstand a moderate level of pest injury.

ADVANTAGES AND DISADVANTAGES OF BIOLOGICAL CONTROL

ADVANTAGES
Biological control offers tremendous social, environmental, as well as economic advantages.

1. SUSTAINABILITY : This method is permanent, and therefore completely sustainable. It can become self-sustaining and integrated in the normal environment of the control area. Since such controls are expected to continue indefinitely, a high initial expense may prove to be a very low total cost.

2. REDUCE RELIANCE ON AGROCHEMICALS: The most crucial use of biocontrol agents is that they help in reducing the use of agrochemicals like pesticides which have harmful effects on human beings and other living creatures in the environment. Bicontrol is particularly useful where chemical pesticides are not suitable or are impractical in environmentally sensitive areas, or on low-unit-value crops, such as alfalfa or soybeans, where complete control may not be required.

3. SAFETY :Biocontrol agents pose no threat to human health, crop production or beneficial organisms. They are environmentally friendly and do not have any side effects on humans.

4. COST EFFECTIVE: These methods are comparatively cheaper than other Agrochemicals like pesticides and insecticides usage. For example, when controlling a weed pest, after the initial costs for getting the bioagents, once the agents are established and have had an impact on the weed the only further expenditure required would be for monitoring activities. But in the case of spraying herbicides, this must be repeated occasionally to control the weeds. Thus, need for regular expenses on herbicide purchase.

5. These methods are also easy to use, readily available, and can be used in any season throughout the year.

6. NATURAL CONTROL AGENT: Biological control is natural and does not rely on the use of man-made chemicals that can adversely impact an ecosystem. It also allows the amount of herbicides required for weed control to be reduced

7. SPREAD : The biocontrol agents ( insects or pathogens etc), multiply and increase in populations easily without being affected by physical or environmental or atimes chemical barriers.

8. LANDSCAPE : While the agents are doing their job, previously out-competed native species can gradually recover and recolonize areas without the need for extensive replanting.

9. ALTERNATIVES TO FARMING OPERATIONS: Biocontrol is a sustainable and natural method of farming. It is an alternative natural method, it does not require the use of chemicals and machinery which can have a negative impact on the environment.

10. ECONOMICALLY EFFICIENT: It is economically efficient and sustainable, as once self-replicating and co-evolved natural enemies are established, they provide control indefinitely without further cost or intervention.
Above all, the key advantages include its high specificity, making it safe for beneficial organisms, and its ability to be cost-effective in the long term due to reduced chemical reliance and avoided crop damage from pests.

DISADVANTAGES OF BIOCONTROL
The excessive use of microbes could have repercussions on the environment, human and even animal health. The introduction of non-native microbes could also lead to ecological and environmental problems if the organism becomes invasive and causes outbreaks or grows excessively, leading to ecological imbalance.
Therefore, resulting in limitation of its effect. Some other disadvantages of biocontrol methods include;

1. The use of biocontrol agents causes a significant and noticeable deterioration in the quality of produce.

2. The biocontrol agents do not eradicate all the pests and are a useful and economical tool for pest control only when used on a large scale.

3. CONTROL NOT ERADICATION : A successful agent should not eradicate the pests like weed on which it depends, but reduce it to acceptable levels instead. There may be costs associated with alternative control methods

4. TIMESCALE : It takes time. It can take between five to 10 years from release to achieve successful control

5. IMPACTS : The complete impact on the target pest is not always predictable. For example, invasive weeds will continue to have a devastating effect on native flora and fauna, damage the built environment and national economies, and affect people’s if proper control measures are not embarked upon.

6. CHEMICAL CONTROL: Chemical herbicides can be effective where permitted, but using this method of control on a large scale is costly and could impact on biodiversity. Many of the worst invaders are aquatic or grow beside rivers where use of chemicals is banned or severely limited

7. MANUAL CONTROL :Manual control methods are available for most invasive weeds but not for other pests like insects. This control are rarely viable on large scale invasions because they are labour-intensive and costly.

CATEGORIES OF APPROACHES TO BIOLOGICAL CONTROL
Biocontrol comprises using living organisms or natural substances to prevent or reduce damage caused by harmful organisms (animal pests, weeds and pathogens). There are 4 categories of approaches to biological control based on the use of control agents such as:

APPROACHES OR STRATEGIES FOR ACHIEVING BIOLOGICAL CONTROL
There are three basic strategies for achieving biological control. These three strategies form the core of most biocontrol programs:

1. CLASSICAL (IMPORTATION): Here, a natural enemy of a pest is introduced in the hope of achieving control. The pest natural enemy introduced occasionally can be a pathogen. This is often a more long-term solution. For example, Rodolia cardinalis, the vedalia beetle, was imported from Australia to California in the 19th century to control cottony cushion scale (Icerya purchasi ) on orange trees. And this action was successful. Also, controlling of Icerya purchasi (cottony cushion scale) in California was achieved successfully using a beetle and a parasitoidal fly called Cryptochaetum iceryae. Other successful cases include the control of Antonina graminis in Texas by Neodusmetia sangwani.
The aim of classical biocontrol is to establish a sustainable population that suppresses the pest for many years. Usually, this approach is used against a pest that is non-native to the area. This is called invasive species. Invasive species are often problematic because they might not have predators in the invaded area. For this reason, the biocontrol agent selected and introduced generally originates from the same area as the invasive species.
Also, the pest’s natural enemies can be imported and introduced to a new locality where they do not occur naturally. In the past, these natural enemies where unofficially introduced and not based on research, and some introduced species became serious pests themselves.
For these biocontrol agents to be effective at controlling a pest, the agent must have a colonizing ability which allows it to keep pace with changes to the habitat in space and time. Control is greatest if the agent has temporal persistence so that it can maintain its population even in the temporary absence of the target species, and if it is an opportunistic forager, enabling it to rapidly exploit a pest population.
Classical biocontrol is the result of years of scientific research. It identifies potential biocontrol agents that could be imported and ensures that they do not harm native species. The environment needs to be suitable for the biocontrol agent to establish as well. Thus, the approach requires rigorous testing and quarantine to ensure the introduced agent is safe and effective.
Before the release of a new biocontrol agent, governments must also approve its introduction. Usually, once governments approve it, scientists release the biocontrol agents into the environment.
Classical biocontrol has been successfully used for many weed and insect pests. One example is the use of the rust fungus Maravalia cryptostegiae to manage the invasive rubber-vine weed Cryptostegia grandiflora in Australia
Other examples include;
The invasive species  Alternanthera philoxeroides  (alligator weed) was controlled in Florida (U.S.) by introducing  alligator weed flea beetle.
The aquatic weed, the giant salvinia (Salvinia molesta) is a serious pest, covering waterways, reducing water flow and harming native species. It was controlled using the salvinia weevil (Cyrtobagous salviniae) and the salvinia stem-borer moth (Samea multiplicalis)  in warm climates especially at Zimbabwe, where a 99% control of the weed was achieved over a two-year period.
Small, commercially-reared parasitoidal wasps, Trichogramma ostriniae, was used as an erratic control on the European corn borer (Ostrinia nubilalis), which is a serious pest of corn. A careful formulations of the bacterium Bacillus thuringiensis are more effective if used for the control of the European corn borer.
The O. nubilalis integrated control releasing Tricogramma brassicae (egg parasitoid) and later Bacillus thuringiensis subs. kurstaki (larvicide effect) reduce pest damages more than insecticide treatments. 

2. INDUCTIVE (AUGMENTATION):
This technique involves mass-rearing and releasing natural enemies to supplement existing populations or introduce new ones to the field. The growers increase the natural enemies and pathogens in an area on a timely basis to fight pests and diseases. It involves the supplemental release of natural enemies that occur in a particular area, boosting the naturally occurring populations there. The natural enemies and pathogens include; predators, parasitoids or microbes. For example Hippodamia convergens, the convergent lady beetle, is commonly sold for biological control of aphids.
The use of biopesticide and biocontrol products, or biocontrol agents, is also part of augmentative biocontrol.
It should be noted that often, natural enemies or pathogens do exist in the environment, however, their populations may not be large enough to control the pest. There needed to be increased for active effectiveness.
Augmentative biocontrol usually have an immediate effect but might not last long. This is why repeated releases of a control agent is carried out.

TYPES OF AUGMENTATION RELEASE APPROACHES
There are two approaches to releasing the biocontrol agent under Augmentation methods . This can also be refered to as types of release. This can be either one ‘big wave’ approach, called inundative release. Or it can also be one ‘small and strategic’ approach, called inoculative release:

i. INOCULATIVE RELEASE : Here, small numbers of the control agents are released at intervals to allow them to reproduce, in the hope of setting up longer-term control and thus keeping the pest down to a low level, constituting prevention rather than cure. It aims to control a pest for a longer period, usually for the season.
An example of inoculative release include: in horticultural production of several crops in greenhouses, periodic releases of the parasitoidal wasp, Encarsia formosa, are used to control greenhouse  whitefly, while the predatory mite Phytoseiulus persimilis is used for control of the two-spotted spider mite.
Inoculative release is usually done when the pest population is low and is more used as a preventative method. The released biocontrol agent can reproduce during the season and continue keeping the pest population low. An example is the application of some bacteria, such as Bacillus amyloliquefaciens.

ii. INUNDATIVE RELEASE: This is a short-term control of a pest. It involves releasing a large number of the biocontrol agent at one time. The large numbers of the control agents are released in the hope of rapidly reducing a damaging pest population, correcting a problem that has already arisen.
For example: The release of the egg parasite  Trichogramma, frequently released inundatively to control harmful moths. Also, the release of ladybirds to control insect pests. This is similar to pesticide treatments with shorter-term reduction. Repeated applications might be needed in this case.
A new way for inundative releases are now introduced, that is, use of drones.
Natural enemies can be released at varying rates to show their effectiveness. For example, Bacillus thuringiensis and other microbial insecticides are used in large enough quantities for a rapid effect. The recommended release rates for  Trichogramma  in vegetable or field crops range from 5,000 to 200,000 per acre (1 to 50 per square metre) per week according to the level of pest infestation.
 Similarly, nematodes that kill insects (that are entomopathogenic) are released at rates of millions and even billions per acre for control of certain soil-dwelling insect pests.

Augmentation can be effective, but is not guaranteed to work, and depends on the precise details of the interactions between each pest and control agent.

3. INOCULATIVE (CONSERVATION):
The conservation of existing natural enemies in an environment means the natural enemies are being protected and their populations being enhanced. It mainly focuses on managing the environment. Such natural enemies are already adapted to the  habitat  and to the target pest. These natural enemies include;
predators, parasitoids, and pathogens. they reduce or eliminate the target organisms or even harm them. The aim is to foster their natural abundance and effectiveness. Their conservation can be simple and cost-effective. For example, cropping systems can be modified to favour natural enemies, a practice sometimes referred to as habitat manipulation. The population of these natural enemies are usually maintained through regular reestablishment.
For the natural enemies to survive , some cultural and mechanical practices are adopted, which include:
-Food sources
-Alternative hosts
-Shelter and refuge habitat
-Appropriate microclimates.
Suitable habitat are required, such as a shelterbelt, hedgerow, or beetle banks etc with the above suitable conditions. Such natural enemies, for example, beneficial insects such as parasitoidal wasps can live and reproduce in such environment. Also, these natural enemies require food. Things such as layers of fallen leaves or mulch, manures, compost, flower nectars etc provide a suitable food source for for the organisms. Such natural enemies include; worms, insects, beneficial mammals like hedgehogs, amphibians, reptiles etc.
Another example is the installation of insect networks. It involves planting strips of local plants near crops to provide resources like pollen and nectar all year round to the natural enemies, parasitoids and predators that would not found in a monocropping system. Plant strips also offer shelter to these organisms.
An example is a wheat field with a flowering border that provides a food source for natural enemies and pollinators.
An example of area where conservative method of pest control had been effective is in Honduras. A type of mosquito called Aedes aegypti was transmitting a fever called dengue fever and other infectious diseases. This mosquito became a serious threat to this country, therefore, biological control method was attempted by a community action plan. Copepods, baby turtles, and juvenile tilapia were introduced into the wells and tanks where the mosquito breeds and the mosquito larvae were eliminated. This was then employed into the water system of the whole country and the mosquito was totally eliminated.
FUNCTIONS OF THE FOOD SOURCES

1. Food source like leaves and manures provides a shelter for worms and insects

2. The worms and insects can in turn become food source for beneficial mammals like hedgehogs and shrews. 

3. Compost piles and stacks of wood can provide shelter for invertebrates and small mammals.

4. Long grass and  ponds can support amphibians.

5. Dead annuals and non-hardy plant’s stems produced during autumn are used by insects. They make hollow in the stems during winter where they leave and keep warm.

6. In California, prune trees are sometimes planted in grape vineyards to provide an improved overwintering habitat or refuge for a key grape pest parasitoid.

Apart from these natural materials utilized by these natural enemies, artificial materials inform of artificial shelters can also be provided. Such shelter include; shelters made in form of wooden caskets, boxes or flowerpots used in gardens, to make a cropped area more attractive to natural enemies. For example,  earwigs  are natural predators that can be encouraged in gardens by hanging upside-down flowerpots filled with straw  or  wood wool. Green lacewings is another natural enemy that can be encouraged by using plastic bottles with an open bottom and a roll of cardboard inside. Bird houses enable insectivorous birds to nest. The most useful birds can be attracted by choosing an opening just large enough for the desired species.
In cotton production, the replacement of broad-spectrum insecticides with selective control measures such as Bt cotton can create a more favorable environment for natural enemies of cotton pests due to reduced insecticide exposure risk. Such predators or parasitoids can control pests not affected by the Bt protein.

REASON FOR ADOPTING BIOCONTROL (INCLUDE IN INTRO)
When pesticides were developed in the 1950’s, they were potent and relatively inexpensive. But with time, the persistence and negative effects of certain pesticides in the environment and some broad spectrum chemical became problematic. Today’s modern pesticides are not as persistent as past pesticides and are important tools in crop protection. These pesticides and other Agrochemicals are very expensive, warranting an integrated approach to pest management, which compliments and promotes the use of biological controls.
The rearing of beneficial insect is carried out in the laboratory or field insectaries. This process takes several years to complete before introduction to the field. When the beneficial insects arrive in the laboratory or insectories, they are relatively new to science, so a mass rearing protocol must be developed by the entomologists reproducing them. They are then released. Follow-up studies are conducted by the laboratory ’s field crew to determine if the natural enemy successfully established at the site of release, and to assess the long-term benefit of its presence.
Certain factors must be considered before final introduction of the beneficial insects.

i. Beneficial insects do not easily adapt for biological control of every insect or weed pest infesting crops.
ii. The pest control program must also be compatible with current grower practices.
iii. A beneficial insect must have the ability to adjust to a new environment and, in the case of an augmentation approach, must lend itself to laboratory production.
iv. The goal of biological control is to bring the pest population down below an economic threshold, not eradicate it. This process brings things into balance and allows native species to compete again.
v. Use of classical biological control takes time. It will take a minimum of six to ten generations and possibly more before to evaluate the impact.

CONSIDERATIONS WHILE SELECTING A BIOCONTROL TYPE FOR FARMING OPERATION
The adoption of all types of biological control – augmentative, conservation or classical – is a crucial step towards safer and more sustainable agriculture.
When farmers want to select the type of biocontrol for effective pest management, the farmer should focus more on augmentative and conservation biocontrol. Augmentative biocontrol provides a quick way to fight pests and diseases. At the same time, conservation biocontrol provides an environment that preserves enemies of these unwanted organisms. Both strategies are beneficial to integrate into the farming practices.
For successful pest management, growers must select the right biocontrol or biopesticide product and provide an environment suitable for beneficial organisms.
For effective control of pests, start using Integrated Pest Management (IPM) to manage crops in an environmentally friendly way.

MECHANISMS OF ACTIONS OF BIOCONTROL AGENTS
The strategies above indicate the role of natural insect enemies on pests. They play an important part in limiting the densities of potential pests. Such biocontrol agents include : predators, parasitoids,  pathogens, and competitors.
Biological control agents of plant diseases are most often referred to as antagonists. Biological control agents of weeds include seed predators, herbivores, and plant pathogens.

a. PREDATORY AGENTS
Predators are mainly free-living species that directly consume a large number of prey during their whole lifetime. They may attack their prey in both its immature and adult stages, usually more than one prey individual is required for the predator to complete its life cycle.
Many major crop pests are insects, that is, many of the predators used in biological control are insectivorous species. The major types that are predaceous include: dragonflies and damselflies, mantids, true bugs, some thrips, lacewings and relatives, beetles, some wasps and ants, and some flies.  Major types of animals that are predators include: birds, fish, amphibians, reptiles, mammals, arthropods, and some plants (e.g., Venus fly trap). Spiders and some mites are also important predators of arthropods.
Some examples of predators and their preys include;
Lady beetles, especially their larvae stage are voracious predators of aphids, and also consume mites, scale insects and small caterpillars. The spotted lady beetle (Coleomegilla maculata) can feed on the eggs and larvae of the Colorado potato beetle (Leptinotarsa decemlineata). The larvae of many hoverfly species principally feed upon aphids, with one larva devouring up to 400 aphids in its lifetime. Their effectiveness in commercial crops has not been studied.
The running crab spider  Philodromus cespitum also prey heavily on aphids, and act as a biological control agent in European fruit orchards.
Predatory Polistes wasp  prey on bollworms or other  caterpillars on a cotton plant.
Several species of  entomopathogenic nematode are important predators of insect and other invertebrate pests. Entomopathogenic nematodes form a stress–resistant stage known as the infective juvenile.
Phasmarhabditis hermaphrodita, a microscopic  nematode that kills slugs.
Species used to control spider mites include the predatory mites Phytoseiulus persimilis, Neoseilus californicus and Amblyseius cucumeris, the predatory midge Feltiella acarisuga, and a ladybird Stethorus punctillum. The bug Orius insidiosus has been successfully used against the two-spotted spider mite and the western flower thrips (Frankliniella occidentalis).
Predatory Cactoblastis cactorum  can also be used to destroy invasive plant species. The poisonous hemlock moth (Agonopterix alstroemeriana) can be used to control poisonous hemlock (Conium maculatum).
The parasitoid wasp Aleiodes indiscretus parasitize on a spongy moth caterpillar, which is a serious pest of forestry.
For rodent pests, cats are effective biological control when used in conjunction with reduction of “harborage” (hiding locations). Cats are also effective at preventing rodent “population explosions”, they are not effective for eliminating pre-existing severe infestations. Barn owls are also sometimes used as biological rodent control.

WORKING MECHANISM OF PREDATORS AS BIOCONTROL AGENTS
The action of predators on pest can be direct or used to regulate the pest population.

1. DIRECT CONSUMPTION:
Predators can directly feed on and kill prey. Such predators include; insects or mites, which are often pests of agricultural production. 

2. POPULATION REGULATION:
Predators can also carry out their actions by consuming multiple prey individuals. They achieve this by regulating and decrease the overall population size of the pest species. 

b. PARASITOIDS
Parasitoids are highly effective biocontrol agents because they are natural enemies that kill pest organisms, typically by having their immature stages develop in or on a host, ultimately killing the host. They are arthropods that parasitize and kill another arthropod (insects, mites, spiders, and other close relatives) host.They are used in classical, augmentative, and conservation biological control programs, leveraging their host specificity, high reproductive rates, and ability to target specific pest life stages to reduce reliance on chemical pesticides. 
During their immature stage, they are parasitic and free living as an adult. They are among the most widely used biological control agents. They are most effective at reducing pest populations when their host organisms have limited  refuges to hide from them. The major types of insects that are parasitoids include: wasps, flies, some beetles, mantisflies, and twisted-winged parasites. 
Adult female parasitoids lay their eggs on or in the body of an insect host, especially at their immature stage. As the larvae develop, they consume the host and kill it. This is achieved by penetrating the body wall with their ovipositor or they attach their eggs to the outside of the host’s body.
During the larvae development, the host is ultimately killed. Insect parasitoids like wasps or flies do have a very narrow host range.
Encarsia formosa, a parasitoid wasp widely used in  greenhouse  horticulture, was one of the first biological control agents developed. It was developed to control the greenhouse whitefly. The most important groups of wasps are the ichneumonid wasps, which mainly use caterpillars as hosts; braconid wasps, which attack caterpillars and a wide range of other insects including aphids; chalcidoid wasps, which parasitize eggs and larvae of many insect species; and tachinid flies, which parasitize a wide range of insects including caterpillars, beetle adults and larvae, and true bugs.
The fly Lixophaga diatraeae has been successfully used in the southern U.S. to control the sugarcane borer, Diatraea saccharalis. And the parasitoid wasps Bathyplectes anurus and B. curculionis are effective biocontrol agents for alfalfa weevil larvae. 

METHODS OF REARING PARASITOIDS
Commercially, there are two types of rearing systems. One of which is the short-term daily output. This rearing system is meant for high production of parasitoids per day, and with long-term, low daily output systems. In most instances, production will need to be matched with the appropriate release dates when susceptible host species are at a suitable phase of development. Larger production facilities produce on a year long basis, whereas some facilities produce only seasonally. Rearing facilities are usually a significant distance from where the agents are to be used in the field, and transporting the parasitoids from the point of production to the point of use can pose problems.
Shipping conditions can be too hot, and even vibrations from planes or trucks can adversely affect parasitoids.

PARASITIOD AND PESTS THEY PREY UPON.
a. Encarsia formosa, a small parasitoid wasp attacks  whiteflies. The whiteflie is a sap-feeding insects which can cause wilting and black sooty moulds in glasshouse vegetable and ornamental crops. The use of Encarsia formosa is the most effective when dealing with low level infestations, and it gives protection over a long period of time. The wasp lays its eggs in young whitefly ‘scales’, turning them black as the parasite larvae pupate.
b. Gonatocerus ashmeadi  (Hymenoptera: Mymaridae) has been used to control the  glassy-winged sharpshooter  Homalodisca vitripennis  (Hemiptera: Cicadellidae) in French Polynesia and has successfully controlled ~95% of the pest density.
c. The eastern spruce budworm  is an example of a destructive insect in fir and spruce forests.

d. Birds are a natural form of biological control, used for controlling diverse numbers of insects, worms etc.
e. Trichogramma minutum, a species of parasitic wasp, has been investigated as an alternative to more controversial chemical controls of the pest.
f. In addition, urban cockroaches has been controlled using parasitic wasps. Most cockroaches remain in the sewer system and sheltered areas which are inaccessible to insecticides, employing active-hunter wasps is a strategy to try and reduce their populations.

c. PATHOGEN

Today, the use of microbial pathogens has become a very popular method of pest management. These pathogenic micro-organisms include;  bacteria, fungi, protozoa, nematodes and viruses.  They kill or debilitate their host and are relatively host-specific. For example , Baculoviruses are viruses that infect insects, causing their bodies to liquefy and release more viral particles to infect other insects.  Fungi,  such as Entomophaga, infect and kill aphids, turning their bodies into a fuzzy, brown, dead husk. Bacteria, like Bacillus and Pseudomonas, can secrete antimicrobial compounds to kill pathogens or compete for nutrients and space, thus protecting plants from diseases like root rot.
Pathogens are diseases causative agents also. Various  microbial insect diseases occur naturally, but may also be used as biological pesticides.

MAJOR PATHOGENS USED IN BIOLOGICAL CONTROL OF INSECTS:

a. BACTERIA
Bacteria used for biological control infect insects through their digestive tracts. They are limited options for controlling insects with sucking mouth parts such as aphids and scale insects. Bacillus thuringi
ensis (Bt), a soil-dwelling bacterium, is the most widely applied species of bacteria used for biological control, with at least four sub-species used against  Lepidopteran  (moth,  butterfly), caterpillars, Coleopteran  (beetle) and Dipteran (true fly) insect pests. Apart from these preys, they also feed on many caterpillar  pests, mosquitoes, and others pests. The bacterium are commercially sold in stores. The genes of these bacterium  can be extracted and  incorporated into  transgenic crops, making the plants express some of the bacterium’s toxins, which are proteins. These boost the plant resistance to insect pests and thus reduce the necessity for pesticide usage. If pests develop resistance to the toxins in these crops, B. thuringiensis will become useless in organic farming.  Another bacterium called  Paenibacillus popilliae causes  milky spore disease, is found useful in the controlling of  Japanese beetle, especially in killing the larvae. It is very specific to its host species and is harmless to vertebrates and other invertebrates.
In addition, bacterium like Bacillus spp., fluorescent Pseudomonads, and  Streptomycetes are used to control various fungal pathogens.
Some bacterial biocontrol agents can produce enzymes, like chitinases, to degrade signal molecules that pathogens use to initiate infection, thereby reducing disease symptoms. This process is called “Quorum Sensing Inhibition”.
In plant infected with diseases for example, antagonistic Bacteria like Bacillus and Pseudomonas can produce  antibiotics or cell-wall degrading enzymes to kill harmful pathogens. 

b. FUNGI

The green peach aphid is a pest and a vector of plant viruses. It can be killed by the fungus  Pandora neoaphidis  (Zygomycota: Entomophthorales).
Other fungi  can kill pests like Metarhizium (cockroach motels), Beauveria bassiana (Colorado potato beetle, Corn rootworms).
Entomopathogenic fungi is a fungus that cause disease in insects. About 14 species of this fungi can attack aphids.  Beauveria bassiana is another fungi that can be mass-produced in order to manage a wide variety of insect pests including whiteflies, thrips, aphids and weevils.  Lecanicillium spp. can be deployed to destry white flies, thrips and aphids.  Metarhizium spp. are used against pests including beetles, locusts and other grasshoppers,  Hemiptera, and spider mites. Paecilomyces fumosoroseus is effective against white flies, thrips and aphids; Purpureocillium lilacinus is used against root-knot nematodes, and some  Trichoderma species against certain plant pathogens. The fungus is a free-living fungus in root ecosystems that controls several plant pathogens.  Trichoderma viride has been used against Dutch elm disease, and has shown some effect in suppressing silver leaf, a disease of stone fruits caused by the pathogenic fungus  Chondrostereum purpureum.
Pathogenic fungi may be controlled by other fungi, or bacteria or yeasts, such as: Gliocladium spp., mycoparasitic Pythium spp., binucleate types of Rhizoctonia spp., and Laetisaria spp.
The fungi  Cordyceps  and  Metacordyceps are deployed against a wide spectrum of arthropods. Entomophaga  for example is effective against pests such as the green peach aphid.
There are also some fungi that are antagonistic in their action. For example, Trichoderma fungi compete for nutrients and space in the soil, limiting food for harmful microorganisms. They also secrete toxic substances like viridin to kill pathogens like Fusarium. 
Several members of Chytridiomycota  and  Blastocladiomycota have been explored as agents of biological control.  From Chytridiomycota,  Synchytrium solstitiale is being considered as a control agent of the yellow star thistle  (Centaurea solstitialis) in the United States.

f. VIRUSES

Baculoviruses, particularly those from the genus Nucleopolyhedrovirus (NPV), are pathogens that attack specific insects and other arthropods. They are mostly specific to individual insect host species and have been shown to be useful in viral biological pest control. For example, the  Lymantria dispar multicapsid nuclear polyhedrosis virus has been used to spray large areas of forest in North America where larvae of the spongy moth are causing serious defoliation. The moth larvae are killed by the virus they ate and died, the disintegrating cadavers leaving virus particles on the foliage to infect other larvae.
A mammalian virus, the rabbit haemorrhagic disease virus was introduced to Australia in an attempt to control the European rabbit populations in the country. The virus escaped from quarantine and spread across the country, killing large numbers of rabbits. Very young animals survived, passing immunity to their offspring in due course and eventually producing a virus-resistant population. Also, in Australia, RNA mycoviruses are used for controlling various fungal pathogens.

g. OOMYCOTA

Oomycetes are used as biological control agents (BCAs) to combat destructive plant pathogens by acting as beneficial organism that can antagonize harmful microbes through mechanisms like mycoparasitism, producing lytic enzymes, outcompeting for nutrients and space, triggering induced resistance in plants, and producing gun cells. Some oomycetes like Pythium oligandrum are beneficial for controlling fungi, bacteria, and even nematodes, others are major crop pathogens. They are eco-friendly disease management strategies. For example, Lagenidium  giganteum is a water-borne mold that parasitizes the larval stage of mosquitoes. When applied to water, the motile spores avoid unsuitable host species and search out suitable mosquito larval hosts. This mold has the advantages of a dormant phase, resistant to desiccation, with slow-release characteristics over several years. Unfortunately, it is susceptible to many chemicals used in mosquito abatement programmes.

OOMYCETES MECHANISM OF ACTION AS BIOCONTROL AGENTS

Oomycetes can control plant diseases through several beneficial mechanisms: 
a. MYCOPARASITISM:
Oomycete can directly colonizes and parasitizes a harmful oomycete or fungus and also inhibite their growth. 
b. LYTIC ENZYME EXUDATION:
Some beneficial oomycete releases enzymes that break down the cell walls of pathogens, thereby destroying them. 
c. COMPETITION: Beneficial oomycetes can compete with pathogens for essential nutrients and space in the soil, preventing the pathogen from establishing itself. 
d. INDUCED SYSTEMIC RESISTANCE (ISR): Some oomycetes can assist plant’s to develop or build their own defense mechanisms. This helps the plant to become resistant and also protect the plant from a broad range of pathogens. 
e. PRODUCTION OF GUN CELLS:
Oomocete can release specialized cells that inject toxic compounds into pathogen cells, thus killing the pathogen. 

h. COMPETITORS

Competitors used as biocontrol agents exploit the principle of ecological competition, where organisms compete for the limited resources like nutrients, space, or infection sites. They colonize an area or infection sites on a host plant, preventing the pathogen from establishing itself. This mechanism reduces the population or growth of harmful pathogens or pests by depriving them of essential resources. These biocontrol agents are strong competitors, mostly found in the rhizosphere (root zone) or phyllosphere (leaf surface), and can outcompete pathogens by possessing high saprophytic ability or even starving the pest.
Some of these biocontrol agents Scavenge for nutrients to produce high-affinity iron-chelating compounds that sequester iron from the environment, making it unavailable for pathogens that require iron for growth.
Examples of Biocontrol Agents used as competitors include; Fluorescent Pseudomonads, a strains of Pseudomonas fluorescens, known for their strong competitive saprophytic ability, outcompeting soil-borne fungi like Fusarium and Pythium for nutrients and space.
Bacillus subtilis is a bacterium which is highly competitive colonizer of plant roots, can effectively prevent pathogens from accessing the roots and causing disease.
Trichoderma asperellum, a fungi that competes with other pathogens for resources and is used in combination with other agents for integrated pest management programs.
The legume vine Mucuna pruriens is used in the countries of Benin and Vietnam as a biological control for problematic Imperata cylindrica grass develop vine that is extremely vigorous and suppresses neighbouring plants by out-competing them for space and light.  Mucuna pruriens is said not to be invasive outside its cultivated area.
 Desmodium uncinatum can be used in push-pull farming to stop the parasitic plant, witchweed (Striga).
The Australian bush fly, Musca vetustissima, is a major nuisance pest in Australia, but native decomposers found in Australia are not adapted to feeding on cow dung, which is where bush flies breed. Therefore, the Australian Dung Beetle Project (1965–1985), led by George Bornemissza of the Commonwealth Scientific and Industrial Research Organisation, released forty-nine species of dung beetle, to reduce the amount of dung and therefore also the potential breeding sites of the fly.

i. COMBINED USE OF PARASITOIDS AND PATHOGENS

In cases of massive and severe infection of invasive pests, techniques of pest control are often used in combination. An example is the emerald ash borer, Agrilus planipennis, an invasive beetle from China, which has destroyed tens of millions of ash trees in its introduced range in North America. As part of the campaign against it, from 2003 American scientists and the Chinese Academy of Forestry searched for its natural enemies in the wild, leading to the discovery of several parasitoid wasps, namely  Tetrastichus planipennisi, a gregarious larval endoparasitoid, Oobius agrili, a solitary, parthenogenic egg parasitoid, and Spathius agrili, a gregarious larval ectoparasitoid. These have been introduced and released into the United States of America as a possible biological control of the emerald ash borer. Initial results for Tetrastichus planipennisi have shown promise, and it is now being released along with Beauveria bassiana, a fungal pathogen  with known insecticidal properties.

j. SECONDARY PLANTS

In addition, biological pest control sometimes makes use of plant defenses to reduce crop damage by herbivores. Techniques include polyculture, the planting together of two or more species such as a primary crop and a secondary plant, which may also be a crop. This can allow the secondary plant’s defensive chemicals to protect the crop planted with it.

CHALLENGES AND SIDE EFFECTS OF BIOCONTROL
All technologies used for agricultural production comes with bountiful benefits especially in increasing yield. With all these benefits, they also come with their own challenges.
Biological control can affect  biodiversity and the environment through predation, parasitism, pathogenicity, competition, or other attacks on non-target species. The use of this technique faces challenges despite the fact that natural living organisms are used. Some of the potential obstacle to the adoption of biological pest control measures include;

1. Potential harm to non-target species and ecosystems.

2. Stringent regulatory hurdles,

3. Difficulty of mass-production 4. Deployment of agents over large areas,

4. Need to balance biocontrol with other pest management methods, and

5. Formulation problems

6. Delivery problems.

7. Assessing the effectiveness, economic benefits, and ecological impacts of biocontrol programs is difficult,

8. The pests can develop resistance to agents.

9. Ecological and Safety Concerns

10. Difficulty in predicting impacts

11. Knowledge Gaps and Evaluation Difficulties

12. Difficulty in Monitoring and Assessment etc

1. POTENTIAL HARM TO NON-TARGET SPECIES AND ECOSYSTEMS:
An introduced control does not always target only the intended pest species, it can also target native species. thus, unintentionally harming the beneficial organism species or disrupt entire ecosystems. Thus, bringing about careful testing and risk assessment.
In Hawaii, during the 1940s, parasitic wasps were introduced to control a lepidopteran pest and the wasps are still found there today. This may have a negative impact on the native ecosystem. However, host range and impacts need to be studied before declaring their impact positive or negative on the environment.
Cane toad (introduced into Australia 1935) spread from 1940 to 1980: was ineffective as a control agent. Its distribution has continued to widen since 1980.

2. Vertebrate animals tend to be generalist feeders, and seldom make good biological control agents, many of the classic cases of “biocontrol gone awry” involve vertebrates. For example, the cane toad (Rhinella marina) was intentionally introduced to Australia to control the greyback cane beetle (Dermolepida albohirtum), and other pests of sugar cane. 102 toads were obtained from Hawaii and bred in captivity to increase their numbers until they were released into the sugar cane fields of the tropic north in 1935. It was later discovered that the toads could not jump very high and so were unable to eat the cane beetles which stayed on the upper stalks of the cane plants. However, the toad thrived by feeding on other insects and soon spread very rapidly. It took over native  amphibian habitat and brought foreign disease to native  toads and frogs, dramatically reducing their populations. Also, when it is threatened or handled, the cane toad releases poison from parotoid glands on its shoulders, native Australian species such as goannas, tiger snakes,  dingos  and northern quolls that attempted to eat the toad were harmed or killed. However, there has been some recent evidence that native predators are adapting, both physiologically and through changing their behaviour, so in the long run, their populations may recover.

3. INTRODUCTION OF EXOTIC AGENTS:
Releasing non-native organisms into an ecosystem carries potential risks to native species and can lead to unintended consequences. For example,
Rhinocyllus conicus, a seed-feeding weevil, was introduced to North America to control exotic musk thistle (Carduus nutans) and Canadian thistle (Cirsium arvense). However, the weevil also attacks native thistles, harming such species as the endemic Platte thistle  (Cirsium neomexicanum) by selecting larger plants (which reduced the gene pool), reducing seed production and ultimately threatening the species’ survival. 
Similarly, the weevil Larinus planus was also used to control the Canadian thistle, but it damaged other thistles as well.
The small Asian mongoose  (Herpestus javanicus) was introduced to Hawaii in order to control the rat population. However, the mongoose were diurnal, and the rats emerged at night. The mongoose, therefore, preyed on the endemic birds of Hawaii, especially their eggs, more often than it ate the rats, and now both rats and mongooses threaten the birds. This introduction was undertaken without understanding the consequences of such an action. No regulations existed at the time, and more careful evaluation should prevent such releases now.

4. COMPETITION AMONG ORGANISMS: The sturdy and prolific eastern mosquitofish  (Gambusia holbrooki) is a native of the southeastern United States and was introduced around the world in the 1930s and ’40s to feed on mosquito larvae and thus combat malaria. However, it has thrived at the expense of local species, causing a decline of endemic fish and frogs through competition for food resources, as well as through eating their eggs and larvae. In Australia, control of the mosquitofish is the subject of discussion;

5. growers may prefer to stay with the familiar use of pesticides. However, pesticides have undesired effects, including the development of resistance among pests, and the destruction of natural enemies. These may in turn enable outbreaks of pests of other species than the ones originally targeted, and on crops at a distance from those treated with pesticides. 

6. TIMING: One method of increasing grower adoption of biocontrol methods involves letting them learn by doing, for example showing them simple field experiments, enabling them to observe the live predation of pests, or demonstrations of parasitised pests. In the Philippines, early-season sprays against leaf folder caterpillars were common practice, but growers were asked to follow a ‘rule of thumb’ of not spraying against leaf folders for the first 30 days after transplanting; participation in this resulted in a reduction of insecticide use by 1/3 and a change in grower perception of insecticide use. This is time consuming.

7. TECHNICAL AND PRACTICAL DEPLOYMENT HURDLES: Biocontrol involves acquiring new techniques and for farmers to use it, it must be accompanied by an advisory service, a research organization, an experimental network, or a Chamber of Agriculture. These assist in maintaining precision in agent application, solve challenges of translating laboratory results to field conditions, resolving issues of non-target effects on beneficial organisms, and also proffer solutions to other challenges like ; assessed of a field biotic risk so as to define which prophylactic measures must be taken, difficulties in maintaining agent viability against environmental stresses, complex regulatory processes, a lack of grower knowledge and confidence, and the inherent difficulty in predicting and controlling long-term ecosystem impacts, identification of precise organisms and substances to use, mastery of application techniques, and a deep understanding of field conditions, which can be challenging to achieve at a large scale.
These challenges can be overcome through advanced research, collaboration, clear regulatory frameworks, and effective communication to build trust and facilitate large-scale adoption.

8. KNOWLEDGE GAPS AND EVALUATION DIFFICULTIES : There are knowledge gaps in biocontrol usage. Such gap include; lack of information for farmers, limited awearness by small scale farmers etc.
More research are needed to provide practical and farm-level cost-benefit analyses rather than complex ecological mechanisms. To quantify the success of biocontrol programs, such as reductions in pesticide use, increased yields, or the return to a natural state, is challenging.
In addition, smallholder farmers often lack sufficient knowledge about beneficial insects and the principles of conservation biocontrol, making them hesitant to adopt these practices.

9. ECOLOGICAL AND SAFETY CONCERNS: These are major challenges in biological control because introduced biocontrol agents must not attack other beneficial or native plants and insects, causing harm to the non-target species, disrupt ecosystems, and producing unintended consequences that are difficult to predict. These risks necessitate extensive pre-release testing and regulatory oversight to ensure agent specificity, but this can lead to delays and may not fully predict real-world ecological impacts. Therefore, biocontrol agent must only be proposed for field release in the invaded range after intensive research and rigorous safety testing must have being carried out so as to ensure that it’s specific to the plant or pest can be controlled.

10. ENVIRONMENTAL FACTORS: Environmental factors can be biotic or abiotic factors that affect biocontrol agents. For example, factors such as soil texture, moisture, temperature extremes, predation, competition, and starvation can significantly impact the efficacy and survival of biocontrol agents in the field, making them difficult to control and optimize.

Biostimulants also termed as plant conditioners or bioeffectors are types of bioformulation which are biological products used in agriculture. Their composition and function differentiate them from other types of bioformulation like Biofertilizers, biocontrol and biopesticides etc. Biostimulants can include a wider range of substances which are microbial or non-microbial like plant extracts, amino acids, or hormones, and can also include microorganisms (bacteria, fungi and algae etc.) or their byproducts. Biostimulants aim to enhance plant performance by stimulating various physiological processes.

DEFINITIONS OF BIOSTIMULANTS

The first legal definition of a biostimulant occur in the United States in 2018, and it was defined as “a substance or microorganism that, when applied to seeds, plants, or the rhizosphere, stimulates natural processes to enhance or benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, or crop quality and yield.”
Biostimulants are substances, cultures of micro-organism, and mixtures of materials used to promote the growth of crop plants and can include natural or artificial plant growth regulators and biofertilizers. They do not include pesticides or fertilizers.

BENEFITS OF BIOSTIMULANTS
A lot of farmers nowadays take to the use of biostimulants based on their benefits. They have shown to have great crop health benefits. But notwithstanding, the mode of action of these products is not fully understood.

Today, many types of biostimulants are used in crop production, and each has different benefits. Common biostimulant effects and benefits on plants include:

1. Generally, biostimulants boost a plant’s vigour

2. It makes crop more tolerant to abiotic and biotic stress and recovery.

3. Biostimulants have a direct mode of action against weeds, diseases, or insects. They are bioherbicides, biofungicides, and bioinsecticides.

4. They improve yield potential and crop quality

5. They can optimize root growth

6. They enhance nutrient uptake

7. Biostimulants may work synergistically with other crop inputs, including fertilizers and pesticides, to improve productivity or increase crop safety.

8. Adding biostimulants to a crop nutrition program may also help fertilizers work harder to improve the return on investment potential of the fertility program.

9. They improve plant water and nutrient uptake, as well as translocation.

10. They can make roots to be more robust in structure and growth

11. Their application makes plants to be diseased tolerant

12. Improved plant metabolism for enhanced yield and crop quality

13. Biostimulants can be used to enhance the effects of chemical inputs, such as beneficial rhizosphere microbiomes including plant growth-promoting rhizobacteria and favorable fungi .

14. Microbial biostimulants can enhance physiological and biochemical processes that improve the absorption of nutrients, increase nutrient utilization, enhance the quality of crops, and boost plant output. Other benefits will be discussed below

CATEGORIES OF BIOSTIMULANTS
Biostimulants can be categorized into two. The natural or synthetic biostimulants.
These two categories are substances that can be applied to seeds, plants, and soil. These substances cause changes in vital and structural processes in order to influence plant growth through improved tolerance to abiotic stresses and increase seed and/or grain yield and quality.

a. SYNTHETIC BIOSTIMULANTS
Synthetic biostimulants are man-made compounds that, when applied to plants, enhance growth, development, and stress tolerance by influencing natural plant processes. They are laboratory-created versions of naturally occurring substances that can trigger positive changes in plant physiology. They are not plant nutrients or pesticides, but rather substances that promote plant health and vigour.

MODE OF ACTION OF SYNTHETIC BIOSTIMULANTS
Synthetic biostimulants work by stimulating a plant’s natural processes, such as nutrient uptake, stress tolerance, and root growth.

PROPERTIES OF BIOSTIMULANTS
Biostimulants  enhance plant growth, development, and stress tolerance. They are not agrochemicals like fertilizers and pesticides but rather work by stimulating natural processes than providing nutrients and destroying pests directly. They can improve nutrient uptake, enhance stress tolerance (like drought or salinity), and promote root development. 
Some of their properties are as follows
PROPERTIES OF BIOSTIMULANTS

1. ENHANCED NUTRIENT USE EFFICIENCY: Biostimulants can improve the way plants absorb and utilize nutrients from the soil, but they themselves do not supply nutrients to the soil. Thus, leading to better growth, yield and productivity. 

2. STRESS TOLERANCE: They can help plants cope with various abiotic stresses, such as drought, salinity, extreme temperatures, and heavy metal toxicity, by stimulating the production of protective compounds and enhancing metabolic processes. 

3. ROOT DEVELOPMENT: Many biostimulants release substances that promote root growth and enlargement, which is crucial for nutrient and water uptake, as well as soil health. 

4. HORMONAL EFFECTS: Some biostimulants contain plant hormones or compounds that influence plant hormone balance, impacting growth and development. 

5. MICROBIAL INTERACTIONS: Biostimulants can also interact with soil microbes whether synagistically or not. Thus, enhancing beneficial microbial activity and nutrient cycling. 

6. NOT FERTILIZERS OR PESTICIDES: Biostimulants differs from fertilizers and pesticides. Fertilizers supply nutrients while pesticides control pests and diseases. Biostimulants only improve the way plants absorb and utilize nutrients.

7. DIVERSE COMPOSITION: Biostimulants can be derived from various sources, including seaweed extracts, humic and fulvic acids, microbial derivatives, and plant extracts. These various sources from which they are produced bring about differences in their working mechanisms.

8. APPLICATIONS: They are used in various agricultural settings, including organic farming and conventional agriculture, to improve crop performance and promote sustainable food production. They can be applied as seed treatment or coating, foliar and application to the rhizosphere.

BENEFITS OF SYNTHETIC BIOSTIMULANTS

1. Improved crop yield and quality:

2. By enhancing plant growth and development, this can lead to increased yields and better quality produce.

3. Enhance stress tolerance:
They can help plants withstand various environmental stresses, including drought, salinity, and extreme temperatures.

4. Increased nutrient uptake:
They can improve the efficiency of nutrient absorption from the soil.

5. Reduced reliance on synthetic inputs:
They have ability to boost plant health, thus, resulting in reduction in the use of synthetic fertilizers and pesticides.
Examples of synthetic biostimulants include substances like salicylic acid, amino acids, humic acids, and seaweed extracts.

i. SALICYLIC ACID:
Can be used to enhance plant resistance to pathogens and improve fruit quality.
ii. AMINO ACIDS:
Can be involved in various metabolic pathways, including protein synthesis, and can be used to enhance plant growth and stress tolerance.
iii. HUMIC AND FULVIC ACIDS:
Can improve soil structure, nutrient availability, and water retention .
iv. SEAWEED EXTRACTS:
Can contain various bioactive compounds that can promote plant growth, improve stress tolerance, and enhance nutrient uptake.

NATURAL BIOSTIMULANTS
Natural biostimulants are organic substances that enhance plant growth and development by stimulating natural physiological processes. They improve nutrient uptake, stress tolerance, and overall plant health, leading to increased crop yield and quality.
They reduce reliance on agro-chemicals. Natural biostimulants can play an important role in this regard by increasing production at a relatively low cost sustainably. Natural biostimulant feedstocks include leaf, root or seed extracts, either individually or in combination with others. Their positive effect is more pronounced in horticultural production due to the plant growth-enhancing bioactive compounds such as phytohormones, amino acids, and nutrients. For example, moringa leaf extracts in particular have been shown to improve seed germination, plant growth and yield, nutrient use efficiency, crop and product quality traits (pre- and post-harvest), as well as tolerance to abiotic stresses. The use of plant-derived biostimulants such as moringa leaf extracts may be an option to reduce quantities needed and thus contribute in achieving global food security sustainably.
Sources of plant based biostimulants include: seaweed extracts, humic substances, amino acids, and microorganisms.

BENEFITS OF NATURAL BIOSTIMULANTS

i. IMPROVE NUTRIENT USE EFFICIENCY :
Natural biostimulants help plants absorb and utilize nutrients more effectively, reducing the need for synthetic fertilizers.
ii. ENHANCE STRESS TOLERANCE:
They increase plant resilience to environmental stressors like drought, salinity, and extreme temperatures.
iii. PROMOTION OF PLANT GROWTH:
Natural biostimulants stimulate various plant processes, leading to better root development, flowering, and overall growth.
iv. SUSTAINABLE AGRICULTURE:
By reducing reliance on synthetic inputs, natural biostimulants contribute to more environmentally friendly and sustainable agricultural practices.
v. DIVERSE SOURCE:
They can be derived from seaweed extracts, humic and fulvic acids, amino acids, protein hydrolysates, and even beneficial microorganisms like bacteria and fungi.

Examples of natural Biostimulants include; Seaweed extracts, humic and fulvic acids,
Amino acids and peptides ( Aid in protein synthesis and hormonal regulation), microbial biostimulants, wood distillate (wood vinegar)- A byproduct of biomass pyrolysis with biostimulant properties and
chitosan ( A natural biopolymer)

MECHANISM OF ACTION
Biostimulants enhance plant growth and development by stimulating various physiological processes, such as cell division, flowering, and fruit set, and improve stress tolerance by activating plant defense mechanisms.
Examples of biostimulants include;
Products containing gibberellins, auxins, or cytokinins (plant hormones), or substances that enhance nutrient use efficiency.
Examples of plant based biostimulants that are based on PGPR and beneficial fungi include; FZB24 fl, Rhizovital 42, Inomix biostimulant, Inomix phosphore, and Inomix biofertilisant. Biostimulants can be hormone-based or protein-based.

CHARACTERISTICS OF BIOSTIMULANTS
Characteristics of produce realised from the use of biostimulants include: sugar content, colour, fruit seeding, etc. Characteristics of biostimulants that result in the characteristics of produce stated above include: their natural or artificially produced origin, diverse composition, and ability to enhance plant performance. 

1. NATURAL OR ARTIFICIAL PRODUCE
Biostimulants can be derived from natural or artificial sources. The natural sources include: seaweed extracts, humic and fulvic acids, and microbial inoculants. The artificial sources are produced through processes like chemical or biological synthesis, creating substances like specific amino acids or peptides. 

2. DIVERSE COMPOSITION
Biostimulants contain a wide array of components, including; microorganisms such as plant growth-promoting rhizobacteria (PGPR) and fungi, plant and algae extracts (These extracts can be from various plants and algae, like seaweed extracts), amino acids and peptides (which are  building blocks of proteins that can influence plant metabolism), humic and fulvic acids (which are  organic compounds derived from decomposed organism matter) etc. These biostimulants improve soil structure and nutrient availability.
In addition, plant hormones, another biostimulant can be natural or synthetic hormones, assist in regulating growth and development. And lastly, minerals and salts. Not all salts have biostimulant effects.
All these determine the characteristics of biostimulants.

3. MODE OF ACTION:
The mode of action of each biostimulant differs from one another. Thus, resulting in differing characteristics of the different biostimulants. For example, some biostimulants enhance nutrient uptake and utilization. They improve the efficiency of nutrient absorption and utilization by the plant. Some build the plant to be stress tolerant. They increase the plant’s resistance to various abiotic stresses like drought, salinity, and extreme temperatures. 
Some bacterial biostimulants assist in plant root development. They stimulate root growth, leading to better anchorage and increased access to water and nutrients. And lastly, some biostimulants are hormone regulators. They can influence plant hormone balance, impacting growth and development. 

4. PHYSIOLOGICAL AND BIOCHEMICAL EFFECTS
This is another characteristics of biostimulant. Biostimulants can induce changes in plant physiology and biochemistry, such as increased antioxidant activity. They are also complementary to the effects of fertilizers.
Note, biostimulants are not fertilizers in the traditional sense (meaning they do not directly supply nutrients). They only work by enhancing the plant’s natural processes to make better use of existing nutrients and tolerate stress, rather than directly providing them. They are often used in combination with fertilizers to optimize plant growth and health.

5. ROLE IN SUSTAINABLE AGRICULTURE:
Biostimulants can reduce the need for synthetic fertilizers and pesticides. These two agrochemicals causes environmental pollution and pests may develop resistance to the use of these chemicals on the long run. Thus. biostimulants promote more sustainable agricultural practices.
By improving plant health and stress tolerance, they can contribute to increased yields and better crop quality.

TYPES OF BIOSTIMULANTS
There are many biostimulant classes and formulations that may stimulate various plant responses. A specific product’s efficacy may be affected by its raw ingredients and how it is manufactured, stored, and applied.
The following are the most common biostimulants used in agricultural production.

A. HUMIC AND FULVIC ACIDS
Both humic and fulvic acids are components that form humified organic matter. They are the largest segment of the biostimulant market. They are organic acids that occur naturally in soil, resulting from the decomposition of plant, animal, and microbial residues. These acids can also come from soil microbe activity. Humic acids may be derived from non-renewable (mineral deposits like leonardite and soft coal) or renewable (compost or vermicompost) sources.

These humic substances can interact with metal ions, oxides, hydroxide, minerals and organic compounds including toxic pollutants, to form water soluble and water insoluble complexes.
Through the formation of these complexes, humic substances can dissolve, mobilize and transport metals and organics in soils and water or accumulate in certain soil horizons. This influences nutrient availability, especially those nutrients present at microconcentrations only. Accumulation of such complexes can contribute to a reduction of toxicity. e.g of aluminum in acid soils,
Fulvic acids and humic acids are the fraction of humus that are soluble in water. fulvic acids is soluble at all pH conditions. They are light yellow to yellowish brown in colour. While humic acids is soluble in more acidic conditions of pH less than 2. They are dark brown to black in colour and larger in molecules than fluvic acids.
Both can be differentiated from one another based on their water solubility.

BENEFITS OF HUMIC ACIDS IN AGRICULTURAL PRODUCTION
Fulvic acids are usually found in forest soils while humic acids are usually found in agricultural or Arable farm soils. Their benefits include:

1. Improving soil physiochemical properties

2. Increasing root nutrient uptake

3. Expanding lateral root development

4. Humic and fulvic substances enhances plant growth directly through physiological and nutritional effects.

5. They function as natural plant hormones ( auxine and gibberellins).

6. They can improve seed germination, root initiation, uptake of plant nutrients and can serve as a source of nitrogen, phosphorus and Sulphur.

7. They can enhance soil water holding capacity and CEC.

B. SEAWEED EXTRACTS AND BOTANICALS
Seaweed extracts are another popular biostimulant class with a long history in agriculture. They promote growth and defense responses to plants. Farmers have used seaweed extracts to fertilize the soil and improve its structure for hundreds of years. However, the biostimulant effects of seaweed extracts are a relatively new development.
Brown seaweeds in the class macroalgae is used as a biomass source to produce seaweed extracts. The species of the genera Ascophyllum, Fucus, and Laminari, are the most commonly used seaweeds in agricultural production. For example, Ascophyllum nodosum is a specie mostly used as raw material to produce organic biostimulants in agriculture.
Different extraction processes are used to produce most seaweed biostimulant products and can affect overall product efficacy. One of these processeses of production is the soft extraction methods. It involves the use of low temperature and pressure and utilizes both physical and chemical techniques for the extraction process. The extracts are usually packaged as a soluble powder or liquid formulation. In the packaging are also included beneficial polysaccharides.

These polysaccharides account for 30-40% of the dry weight of the seaweed extracts and are known to elicit plant defense responses against bacterial and fungal pathogens. In addition to this, several bioactive compounds, such as polyphenols, polysaccharides, lipids, and amino acids, macro- and micronutrients and plant phytohormones are also included in the package. All these gives the biostimulant a positive response when applied.
One of the positive effects of applying seaweed extract in agriculture include:
In the nursery phase, where seedlings are raised from seeds, the main management practices carried out include; supply of organic or chemical fertilizer, according to the requirements of the seedlings, to supply adequate nutrition combined with an adequate supply of water, avoiding both an excess and a lack thereof to ensure the healthy development of the seedlings. But through researches, incorporation of seaweed extract has proven efficient in the development, nutrition, and quality of some seedlings. At this stage, foliar application of these biostimulant is of best practice. And slight irrigation is required.

OTHER BENEFITS OF SEAWEED EXTRACTS

1. Improved plant growth and development from phenolic-rich compounds

2. mproved nutrient uptake and utilization

3. Soil conditioning and metal-chelating properties

4. Increased water retention capacity in plants

5. Improve the yield in different growing conditions.

6. They induce stress tolerance, and increasing nutrient absorption.

These benefits makes them important for sustainable agricultural management. Other plant extracts are increasingly being studied and used for their biostimulant effects.

C. BENEFICIAL BACTERIA
Beneficial bacteria, particularly plant growth-promoting rhizobacteria (PGPR), are increasingly recognized as biostimulants, offering a sustainable approach to enhance plant growth and resilience. Some of these Plant-growth-promoting bacterias (PGPBs) include; free-living bacteria that inhabit a plant’s root zone, bacteria that colonize the root surface, and bacteria that live within plant roots. Examples include;
Bacillus, Rhizobium, Pseudomonas, Azospirillum, and Azotobacter bacteria. Beneficial bacteria may be inoculated on the seed or applied directly to the soil.

ACTIVITIES/EFFECTS OF BENEFICIAL BACTERIA AS BIOSTIMULANTS

a. DIRECT EFFECT:
i. NUTRIENT ACQUISITION: Biostimulants primarily enhance a plant’s ability to absorb and utilize nutrients rather than directly providing them. Biostimulants can improve nutrient uptake by influencing plant physiology, soil health, and microbial activity. Some beneficial bacteria, like phosphate-solubilizing bacteria (PSB), convert unavailable forms of phosphorus into plant-available forms, increasing phosphorus uptake.
ii. HORMONAL PRODUCTION:
Bacterial biostimulants enhance plant hormonal production through various mechanisms, thus, promoting plant growth and development. Bacteria like Plant Growth-Promoting Rhizobacteria (PGPR), can synthesize and release phytohormones like auxins (e.g., IAA), cytokinins, and gibberellins, which are crucial for root growth and shoot development, cell division, and other plant processes, leading to better nutrient and water absorption. Additionally, they can influence the plant’s own hormonal balance and improve nutrient uptake, contributing to overall plant health and stress resilience.

iii. STRESS TOLERANCE: Certain bacteria can produce siderophores (iron-chelating compounds) that help plants acquire iron, and some can also produce ACC deaminase, which reduces the harmful effects of ethylene, a stress hormone.

b. INDIRECT EFFECTS
i. COMPETITION WITH PATHOGENS:
Beneficial bacteria can compete with pathogens indirectly. As biostimulant, they influence plant health and defense mechanisms. They can compete for resources like nutrients and space, reduce pathogen populations and indirectly enhance plant growth and resistance. PGPR for example, can compete with plant pathogens for resources in the rhizosphere, reducing the incidence of diseases. This competitive advantage can also trigger induced systemic resistance (ISR) in plants, making them more resilient to future pathogen attacks.

ii. INDUCED SYSTEMIC RESISTANCE:
Induced Systemic Resistance (ISR) in plants, triggered by beneficial microbes, indirectly enhances plant health and growth, acting as a biostimulant. This indirect effect is achieved by the microbes stimulating plant growth, increasing nutrient uptake, and promoting tolerance to both biotic and abiotic stresses.
They can trigger the plant’s natural defense mechanisms, making it more resistant to both biotic (e.g. diseases, pests) and abiotic (e.g. drought, salinity) stresses.

iii. IMPROVED SOIL HEALTH:
Biostimulants enhance plant growth and stress tolerance, but their effectiveness is significantly influenced by the underlying soil health. Healthy soil provides better nutrient availability, improved water retention, promoting root growth and nutrient cycling. Thus, making beneficial bacteria a contributor to overall soil health and fertility. These fertile soils support more diverse and active microbial community, all of which contribute to the success of biostimulant applications

Examples of Beneficial Bacteria Used as Biostimulants:
i. Bacillus: They are known for promoting plant growth, producing enzymes, and protecting against pathogens. 

ii. Pseudomonas: They are known for their ability to solubilize phosphate, produce siderophores, and promote plant growth. 

iii. Azotobacter: A free-living nitrogen-fixing bacterium that can be a valuable biofertilizer. 

iv. Azospirillum: A nitrogen-fixing bacterium that promotes root growth and nutrient uptake. 

v. Rhizobium: A bacterium that forms symbiotic relationships with legumes, fixing nitrogen in root nodules. 

APPLICATIONS OF BENEFICIAL BACTERIA

i. Beneficial bacteria are used as biofertilizers to enhance nutrient availability and uptake. 
ii. They have biostimulant properties. Thus, promoting plant growth and resilience. 
iii. Microbial biostimulants offer a sustainable alternative to synthetic fertilizers and pesticides, thus, contributing to climate-smart agriculture practices. 
iv. They are used in laboratory studies. In this studies, under field trials, microbial biostimulants, are used to validate efficacy under real-world conditions. 
v. Research is ongoing to develop targeted microbial biostimulants that can be effectively used in different crops and under various environmental conditions. 

OTHER BENEFITS OF PGPBs.

1. Improved water and nutrient uptake

2. Increased nutrient use efficiency

3. Plant hormone stimulation and regulation

4. Resistance to insects and non-beneficial bacterial pathogens

5. Bacterias like rhizobacteria have the ability to fix nitrogen into the soil.

6. They increase stress tolerance, and boost overall plant health and productivity.

While the modes of action and benefits of PGPBs are well understood and documented, they can be challenging to work with because they are living organisms sensitive to handling and extreme temperatures. PGPB biostimulants may not mix well with other crop protection products and often have limited shelf lives.

E. BENEFICIAL FUNGI
Beneficial fungi, particularly arbuscular mycorrhizal fungi (AMF), are increasingly recognized as valuable plant biostimulants. This mycorrhizal fungi are vital to soil health and crop production. They live symbiotically with plant roots to increase root mass, nutrient and water uptake. They also improve stress tolerance, and promote overall plant health and growth.
Specific Examples:
i. Arbuscular Mycorrhizal Fungi (AMF):
Form symbiotic relationships with a wide range of plants, improving nutrient and water uptake, and enhancing stress tolerance.
ii. Ericoid Mycorrhizal Fungi (ErM):
Form symbiotic relationships with plants in the Ericaceae family, like blueberry and cranberry, aiding in nutrient uptake in acidic soils.
iii. Trichoderma spp.:
Can act as biocontrol agents, protecting plants from pathogens and pests, and also promoting plant growth.
BENEFITS OF AMF

1. PROMOTION OF PLANT GROWTH:
By improving nutrient and water availability, and enhancing stress tolerance, AMF contribute to overall plant growth and development.
Inoculation with AMF has been shown to increase leaf area, biomass, and yield in various crops, including tomato and basil.

2. ENHANCE NUTRIENT AND WATER UPTAKE:
AMF extend the reach of plant roots through their hyphae, accessing nutrients and water that would otherwise be unavailable. This can lead to increased uptake of phosphorus, nitrogen, and other essential minerals, improving plant nutrition and growth.
AMF can also improve water uptake, making plants more resilient to drought conditions.

3. INCREASE STRESS TOLERANCE:
AMF can help plants withstand various abiotic stresses like salinity, drought, and heavy metal toxicity.
They achieve this by altering plant metabolism, improving root architecture, and enhancing antioxidant activity.
For example, AMF inoculation has been shown to protect Ocimum basilicum (basil) against salinity stress.

4. BIOCONTROL AGENT:
Some beneficial fungi, like certain Trichoderma spp., can act as biocontrol agents, protecting plants from pathogens and pests. They can suppress the growth of harmful fungi and bacteria, reducing the need for chemical pesticides.

5. SUSTAINABLE AGRICULTURE:
AMF offer a sustainable and environmentally friendly alternative to chemical fertilizers and pesticides.
Their use can reduce the reliance on synthetic inputs, minimizing environmental impact and promoting more sustainable agricultural practices.

Other benefits of symbiotic fungi products include:
i. Increased drought stress tolerance
ii. Improved phosphorus uptake in phosphorus-deficient soils
iii. Beneficial antifungal properties against plant fungal diseases

F. CHITOSAN AND OTHER BIOPOLYMERS
Chitosans, a natural polysaccharide, are derived from a naturally occurring biological building block, chitin and chitosans, sourced from crustaceans and fungi. It support fungal cell walls and the exoskeletons of insects. Chitosans can induce plant-defense responses, making plants more tolerant to abiotic and biotic stresses. It also enhance plant growth, development, and stress tolerance. Although these products’ exact modes of action have yet to be fully understood, more research is being done to support further product development.

ROLE OF CHITOSAN AS A BIOSTIMULANT:
i. GROWTH PROMOTION:
Chitosan plays a multifaceted role in promoting plant growth and health. As a biostimulant, it enhances plant defense mechanisms, improve nutrient uptake, stimulating various plant responses, including root development, enhances plant growth and increase tolerance to various stresses. Additionally, chitosan can be used as a biopesticide, inhibiting the growth of plant pathogens and reducing the need for synthetic chemicals.

ii. STRESS TOLERANCE:
Chitosan is a natural biopolymer that enhances plant stress tolerance by modulating various physiological and molecular responses. It helps plants withstand abiotic stresses like drought, salinity, extreme temperatures and heavy metal toxicity, as well as biotic stresses like diseases. It also improving resistance to pathogens. Chitosan achieves this by activating antioxidant enzymes, enhancing photosynthesis, and influencing gene expression related to stress response.

iii. DEFENCE MECHANISM:
Chitosan, has the capacity to trigger plant’s immune system and enhance its resistance to pathogens and abiotic stresses. It achieves this through various pathways, including inducing the production of protective compounds, strengthening cell walls, and stimulating signaling pathways that activate defense genes.

iv. SEED GERMINATION AND and POST-HARVEST TREATMENT:
Chitosan also assist in seed germination and post-harvest treatment. It enhances seed germination and seedling growth by forming a protective barrier around the seed ( called seed coating) to protect the seeds against pathogens and regulate water uptake. In the case of post-harvest applications, chitosan acts as an antimicrobial and film-forming agent, extending shelf life of the harvested crops. This is achieved by reducing water loss, gas exchange, and microbial growth. 

OTHER BIOPOLYMERS AND THEIR APPLICATIONS
i. ALIGINATE:
Often used in combination with chitosan, alginate can form hydrogels for controlled release of biostimulants and other beneficial compounds.
ii. OTHER POLYSACCHARIDES:
Various other polysaccharides, such as those derived from seaweed, are also being explored for their biostimulant properties.

BENEFITS OF CHITOSANS
The benefits of chitosans and similar biopolymers include:

1. Antibacterial, antifungal, and antiviral properties

2. Soil amendment

3. It possesses characteristics to reduce Fusarium wilt and other soilborne pathogen populations

4. Improve crop yield, quality, and resistance to various environmental stressors.

5. Biopolymers like chitosan can activate plant signaling pathways, leading to the expression of genes involved in growth, defense, and stress responses.

6. They can also influence soil properties

7. They improve nutrient availability,

8. They enhance the plant’s ability to absorb water and nutrients.

CONSIDERATION IN SELECTING BIOSTIMULANT TO APPLY ON FARM
In choosing the right biostimulant product, many options must be put to consideration. Such considerable options include:

1. DEFINITION OF GOALS: The first step in making a decision about the type of biostimulants to choose is to define ones goal. For example; is the product to be selected is to enhance root mass or improve soil fertility, is it to control pest and diseases or to control weeds etc. This specific goal will help to narrow down ones options.

2. PRODUCTION PRACTICES: Next, consider your current production practices. What equipment and labor resources do you have? Are there product formulations that work better with your current production practices? For example, some PGPR formulations are manufactured to have a longer shelf life than most products. Paying more for those formulations will buy you more flexibility and peace of mind that products will still work even if your plans are delayed.

Because biostimulants are relatively new, metrics and data are necessary to sort out the reliable technologies from the gimmicks. Biostimulants are lightly regulated. Merchants make many product claims, and all sorts of concoctions are purported to be biostimulants. Ask questions and ensure you receive a scientific explanation and validated data to support product efficacy in your fields.

APPLICATION OF BIOSTIMULANTS
The application timing of a biostimulant will depend on several factors, including:

a. Product class
b. Formulation
c. Agronomic objective
d. Environmental conditions
e. Crop type

For example,
A. microbial biostimulants:
I. PGPBs and fungi microbial biostimulants: They are often applied as seed inoculants or directly to the soil at planting to stimulate strong early-season plant growth.
ii. Other biostimulants are formulated to work synergistically with fertilizer applications and will be most effective when incorporated into soil fertility program.
B. Non-microbial biostimulants may be applied repeatedly throughout the season using any of these approaches:
i. Calendar application : Preferable when the crop experiences sub-optimal conditions for most of the growing cycle. This strategy is most common in high-value crops in greenhouse growing environments.
ii. Growth stage application : Multiple biostimulant applications at key growth stages (germination, flowering, grain production) may be more profitable in commodity crops.
iii. Environmental stimulus application – For stress mitigation, biostimulants may be applied several days before the stress event (for example, extreme temperatures) for extra protection and after the event to hasten plant recovery.

APPLICATION METHODS
Biostimulants can be administered to plants by seed, foliar, or rhizosphere treatment. With this, they can be categorized as formulations of microorganisms or microbial consortia.

DIFFERENT BIOSTIMULANT TECHNIQUES FOR ENHANCING PLANT DEVELOPMENT

1. PLANT GROWTH-PROMOTING RHIZOBACTERIA (PGPR): These are a diverse collection of bacteria that live inside plants and can enhance plant growth and yield by producing phytohormones, antioxidants, osmolytes, volatile compounds, exopolysaccharides, and 1-aminocyclopropane-1-carboxylate deaminase.

Similarly, probiotics and prebiotics formulated into functional foods, dietary supplements, and pharmaceuticals support gut health and immune function, promoting overall well-being and disease prevention.

c. ENVIRONMENTAL REMEDIATION: Environmental remediation can be achieved through efforts from bioformulation to mitigate pollution, restore ecosystems, and improve water and air quality. Through bioremediation technologies, microbial consortia and enzymes are used to degrade organic pollutants, such as petroleum hydrocarbons, pesticides, and industrial chemicals, turning them into harmless byproducts. Additionally, biofilters containing microbial biofilms or plant-based sorbents capture and metabolize pollutants from air and water streams, providing cost-effective and sustainable solutions for pollution control and remediation.
Azotobacter as a biostimulant has the ability to remove oil contamination, tolerate heavy metals, and degrade pesticides. Azotobacter salinestris exhibit a high tolerance towards metal-oxide nanoparticles (NPs).
The introduction of Cd- and Pb-resistant PGPR (Plant Growth Promoting Rhizobacteria) strains Bacillus sp. QX8 and QX13, isolated from soil polluted with heavy metals, resulted in enhanced growth of Solanum nigrum and increased extraction of Pb and Cd from the soil through plants.

d. INDUSTRIAL APPLICATIONS:
Microbial bioformulations are used in industrial processes to produce enzymes for various applications, including detergents, food processing, and biofuel production. In addition, most industries produce a lot of wastes that when released, pollute the environment. Therefore, to prevent this, bioremediation using bioformulation is usually employed. The microorganisms in bioformulation assist in cleaning up the contaminated sites by breaking down the pollutants in soil and water.
Other industrial areas where bioformulation is applicable include: Bioplastics- where some bioformulations are used in the production of biodegradable plastics.
Food and Beverage Industry- where microbial cultures are used in food production, such as fermentation processes. And lastly, textiles industry where bioformulations are used to develop eco-friendly textile treatments.

e. BIOFORMULATION IN HORTICULTURAL CROPS PRODUCTION

Microbial biostimulants enhance plant nutrition by absorbing mineral elements beyond the areas where the plant roots are actively depleting them. This leads to alterations in secondary metabolism and a rise in the amount of beneficial chemicals in the plants. An example of a biostimulant, which is based on microorganisms, consists of two strains is arbuscular mycorrhizal fungi (AMFs) and Trichoderma koningii. This biostimulant enhanced the quality of plants, independent of the amount of water available.
Utilizing AMFs and PGPRs can enhance the absorption of nutrients from the soil, hence enhancing plant growth, improving fruit quality, and increasing overall output. Under abiotic stress, these two fungi can also be used where crop growth is hindered or meets substantial constraints. For example, the fungus Aspergillus flavipes can synthesize indole-3-acetic acid (IAA) by utilizing soybean bran as a growth substrate.
Also, the concurrent use of plant growth-promoting bacteria and freshwater algae, can increase plant weight of vegetables such as romaine and leaf lettuce over the summer and spring seasons.
Other functions of microbial bistimulants in horticulture include;

1. They provide defense against salt stress, drought stress, and other environmental adversities.

2. Plant Growth-Promoting Rhizobacteria (PGPRs) are essential for sustainable horticultural crop production. They enhance germination, stimulate growth, and improve the look, nutritional content, and texture of vegetables.

3. Azospirillum is a kind of bacteria that promotes the development of plants roots. It also fix nitrogen and produce phytohormones.

4. Azospirillum bacteria also mitigate the harmful effects of salt stress on chickpea growth and performance, enhancing product quality, improving chlorophyll content, prolonging storage life, and promoting higher germination and vegetative growth.

5. Azotobacter promotes plant development through actions, including the generation of growth hormones, siderophores and nitrogen fixation. For eample, in tomato plants, this bacteria enhances photosynthesis, greater flower development, higher fruit yield, and elevated lycopene levels .

6. Bacterias Pseudomonas stutzeri and Bacillus toyonensis can enhance the growth of tomato plants under salt-stress conditions.

7. The introduction of Bacillus amyloliquefaciens during seed germination has also lead to the greatest improvement in seed germination (84.75%) and seedling vigour (1423.8), as well as an increase in the vegetative development parameters of chili (Capsicum annum L.).

8. Arbuscular mycorrhizal fungi (AMFs) have been found to enhance plant nutrient absorption, promote plant growth and yield, and improve the quality of the final product. AMFs has also shown significant potential in suppressing phytopathogens .
Arbuscular mycorrhizal fungi (AMF) can enhance the development of horticultural plants, including fruit trees, vegetables, flower crops, and ornamental plants.

9. Piriformospora indica, a fungus with characteristics similar to mycorrhiza, has been found to be a more effective alternative to AMF in its use on citrus trees.

10. AMF (Arbuscular Mycorrhizal Fungi) and vermicompost have the ability to enhance the absorption of water in cactus plants and reduce the negative effects of drought, while also reducing the presence of oxidative stress indicators. When tomato plants are subjected to restricted watering, certain strains of arbuscular mycorrhizal fungi (AMF) have the ability to enhance plant development and recover the dry weight of both the shoots and roots.
