CABI has initiated activities with Koppert Biological Systems to increase the fight against crop pests and diseases which threaten the food security and livelihoods of thousands of farmers and their families in Kenya.
CABI has signed a collaboration agreement with Koppert to deliver more Plantwise plant doctor training in Kenya, with funding from the Koppert Foundation. This includes plans to further raise the awareness and promotion of biocontrol methods as part of integrated pest management (IPM) advice given to farmers.

Insect pests cause almost half of the crop losses in Africa. If the continent is to feed its growing population, farmers must find ways to control them. Pests account for high losses in other developing regions too.
For smallholder farmers in particular, pest management needs to be affordable, safe and sustainable. It should avoid the drawbacks of synthetic pesticides as far as possible. Research is now showing that integrated approaches can achieve these goals.
10 years ago the Coconut Rhinoceros beetle (CRB) was first discovered on the western Pacific island of Guam. Since then, these shoe-shine black, miniature invaders have spread to all parts of the island and are laying waste to the local coconut and oil palm population. The economy, culture and ecology of Guam and other Pacific islands are intrinsically linked to the native palm species such that the rhino beetle poses a major threat. The indigenous peoples of Guam have a long history of weaving palm fronds, an artistry that is now at risk due to the rhino beetle. These trees are a symbol of tropic paradise, a motif that drives Guam’s primary industry; tourism. Continue reading
Last week, CABI confirmed that since it arrived in Africa in 2016, the Fall Armyworm (FAW) has been reported in 28 African countries, presenting a now permanent agricultural challenge for the continent. FAW mainly affects maize and can cut yields by up to 60%. In research funded by the UK’s Department for International Development (DFID), CABI estimate that, if not properly managed, the pest will cost 10 of Africa’s major maize producing economies a total of $2.2bn to $5.5bn a year in lost maize harvests.

A severe infestation of the papaya mealybug (Paracoccus marginatus) nearly wiped out papaya orchards in Pakistan before the largely farmed country decided to replace conventional chemical pesticides that were ineffective with natural predators that proved to be successful.
The system was developed by agro-biotechnologists and entomologists at the Pakistani chapter of the UK-based Centre for Agriculture and Bioscience International (CABI) who introduced the use of Acerophagus papayae, a parasitoid (insects whose larvae parasite upon and eventually kill the host), to effectively control the mealybug infestation.
Here’s a taste of some of the latest stories about plant health, including the researchers attempting to prevent pest beetles entering avocado crops in Mexico, the use of weaver ants in pest control to reduce pesticide use and the colonisation of crops such as lettuce with secondary pathogens.
