Trapping coffee beetles with natural baits. Validated RNRRS Output.


This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Summary for Project titles: R6928: Development of pheromones for management of coffee white stemborer, Xylotrechus quadripes and R7246.
Natural chemical extracts—pheromones—that attract female coffee stemborers are now being commercially manufactured in India. This new bait, together with specially designed traps, means that females can be caught and destroyed. The coffee white stemborer is a beetle that seriously damages coffee crops in India, Sri Lanka, China, Vietnam and Thailand. In India, coffee growing, as well as providing a living for over half-a-million workers and their families in remote rural areas, checks soil erosion on hillsides. Farmers in all the main coffee-growing areas of India, Karnataka, Kerala, Tamil Nadu and Andhra Pradesh, now use over 40,000 pheromone traps. Since the only pesticide effective on stemborer has been withdrawn from use in India, there is major potential for these traps to help control this major pest of coffee.
