What are Natural Enemies Field Reservoirs, and how do they help farmers control crop pests?
Classical biological control (CBC) is a widely used type of biological control that is proven to be effective in managing invasive pests. This method involves releasing natural enemies like parasitoids or fungi that can keep pest populations under control. However, additional technology, such as natural enemies field reservoirs – or NEFRs – can improve CBC…
Advancing pest management in Grenada through PlantwisePlus biological control training
In a remarkable effort to enhance agricultural practices, Grenada’s Ministry of Agriculture recently hosted a pivotal training course on biological control organized and co-funded by CABI’s PlantwisePlus programme in collaboration with Sandals Foundation*. The course provided participants with a comprehensive overview of biological control strategies tailored specifically to Grenada’s agricultural context.
Types of biological control: augmentative, conservation and classical
Biological control, also called biocontrol or bioprotection, is a method of pest control using other organisms, natural enemies, pathogens, semiochemicals and natural substances. Unlike some other methods of control in agriculture, bioprotection often has little to no side effects.
Parasitic wasps play pivotal role in Kenya’s papaya mealybug control
Papaya mealybug (Paracoccus marginatus) is a devastating papaya pest. It impacts many countries in East and West Africa. Infestations can result in significant economic losses, posing a threat to the livelihoods of smallholder farmers. On average, the pest can cause anywhere from 53% to 100% crop losses, costing £2,224 per hectare annually. Its impact on…

Kenyan farmer perceptions of biological control of papaya mealybug
The papaya mealybug problem in Kenya The invasive papaya mealybug (Paracoccus marginatus) is a devastating pest to many crops, with a host range of over 200 plants. The species was first detected in Africa in 2010 in Ghana and then in 2016 in Mombasa County in Kenya. In Kenya, where horticulture makes up 60% of…
Biocontrol agent released to safeguard crops from parthenium weed in Pakistan
Invasive plants can be extremely harmful to crops. “Famine weed” or parthenium is one such plant. Native to tropical America, it was accidentally introduced to several countries. In Pakistan, the weed now covers thousands of hectares of agricultural and rangeland. And it poses an economic burden to farmers.
Controlling the papaya mealybug pest – progress made in coastal Kenya
An initiative to combat the destructive papaya mealybug in Kenya is reaping rewards. A natural predator – a parasitic wasp – has been introduced to coastal counties to help control the pest. This tiny wasp is helping to prevent the damage caused by the mealybug. It’s not only helping to save papaya farms. It’s safeguarding…
How can Metarhizium be used to address pests and diseases?
Sihle Nakombe is a lab technician from CABI’s office in Zambia. She joined CABI in January 2023. Earlier this year, she visited the CABI labs in Egham, UK, to get training on Metarhizium. This naturally occurring fungus can control insect pests with low environmental and human health effects.
Overcoming gender barriers to tomato farming in Pakistan
Tomato is an important crop in Pakistan – every year, the country produces 4.2 million tonnes of tomatoes. Growing them can be labour intensive. But research shows that tomato production has the potential to generate good incomes for rural smallholders. This includes incomes for women farmers. In Pakistan, women account for over 60% of active…
