In Nepal, the gall-inducing eupatorium gall fly (Procecidochares utilis) is deployed as a biological control agent against the invasive weed Ageratina adenophora. A new study by researchers at Tribhuvan University and the Feed the Future Innovation Lab for Integrated Pest Management shows size and abundance of galls induced by the fly are influenced by elevation, knowledge that can help in fine-tuning P. utilis-based biocontrol efforts.
In a new special collection on trap and cover crops in integrated pest management, experts review the latest research on various habitat-management methods and their applications in both deterring pest populations and fostering natural enemies of crop pests.
The fall armyworm's impact on maize earns plenty of attention, but it is in fact polyphagous. Sorghum, a key cereal crop in Africa, is also vulnerable to the pest's damage, and researchers are working on biocontrol and other integrated pest management methods in hopes of containing the fall armyworm's impact around the world.
A new study shows that growing a variety of crops in the same field increases local insect diversity and even improves the ratio of natural-enemy insects to pest insects.
