Summary for Project title: R7891: Ecology and management of rice hispa (Dicladispa armigera) in Bangladesh.
A computer program to help predict likely outbreaks of the insect pest, rice hispa, is now available. Rice hispa is a serious pest in Bangladesh—up to half the crop can be lost—and in other countries in tropical Asia. The insects are almost everywhere in small numbers and, given the right conditions, plagues erupt dramatically. Now, pest control teams have a simple model—based on humidity levels the previous winter—to forecast outbreaks. This means they can warn farmers. Farmers then use sweep netting and spot applications of insecticide to control the insects, methods proven by small rice growers in Sylhet, northeastern Bangladesh. These methods are now being spread by farmer field schools. This integration of national forecasting with farmer action has great potential for ricegrowing areas.
