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.
Different doctors treat different types of diseases. When the villagers of Rohal Suong in Cambodia feel sick, they can consult a doctor. Now when their crops are sick, they can also go to another doctor, a plant health advisor, who can provide information on the best methods to treat crop pests and diseases.

Computer animations are a rather special and exciting communication medium. For example, they can be used to illustrate the basic biology of pests and diseases and explain control measures. Animations are also an effective way to show changes that occur over a long time or at the landscape, watershed or even the global level. A combination of animation with spoken explanations can make such phenomena much easier to grasp. Being able to ‘see’ the phenomenon helps viewers imagine why individual or collaborative actions may be needed to address otherwise hidden problems. Continue reading →
There’s a pretty simple way we could be feeding an additional 150 million hungry people around the world. It’s not through some super advanced technology or billion-dollar idea that someone just came up with. The answer has been right in front of us for a very long time:
Women. Women farmers are a secret weapon to fighting hunger.
By Katie Tomlinson. Reblogged from the Cabot Institute blog.
Two weeks ago I organised a visit to a plant clinic in the Mukono district of central Uganda. The plant clinics are run by district local government extension staff with support from CABI’s Plantwise programme and offer a place where farmers can bring crop samples to get advice on how to prevent and cure diseases.
Why does Uganda need plant clinics?
It’s estimated that smallholder farmers loose 30 – 40% of their produce to plant health problems before harvest, which threaten food security, income and livelihoods. Ugandan farmers suffer heavily from pests and diseases, including maize stalk borer, wheat rust, banana bacterial wilt, coffee wilt and cassava viral diseases. The situation is always changing, as outbreaks of disease emerge and persist across the country.
Climate-smart agriculture calls for pest management that controls farm pests and diseases in a way that does not negatively affect ecosystem services and human health.
Climate change affects not only farming practices in that extreme events may flatten trees and crops. It also affects the distributions and life cycles of animals and insects such as pests, disease-causing organisms and crop-pollinating insects and animals. Farmers in Vietnam speculate that the increase in temperatures brought about by climate change might be favouring certain pests.
To further understand the behavior, control and management of pests and diseases in the light of climate change, the Centre for Agriculture and Biosciences International (CABI) Southeast Asia is conducting “Pest Smart”, a two-year initiative under the CGIAR Research Program on Climate Change, Agriculture and Food Security Southeast Asia (CCAFS SEA) Climate-Smart Villages (CSVs) project.
