Field trials with 73 formulations of 55 different insecticides including 10 organochlorines (OC), 26 organophosphorous compounds (OP), 12 carbamates, 4 synthetic pyrethroids (SP) and 3 mixtures have revealed that only OCs provide good control of the pest, Hypothenemus hampei. Laboratory screening of 39 formulations of 25 insecticides demonstrate high susceptibility of the pest to several OCs, OPs and SPs. Timing of first application of endosulfan in relation to crop phenology when the berries are about 7mm long and the bean is at 'mung' stage of development, is critical in controlling the pest. Subsequent applications extend the protection but do not help its management for the next year. The paper emphasises the need to understand the pest's biology and behaviour, to develop more persistent formulations of some OPs and SPs, and to integrate chemical spraying with other methods of control.....
