Susceptibility of Callosobruchus sp. collected from Various NSP Centres to Insecticides

Susceptibility of pulse beetles Callosobruchus maculatus and C. analis collected from different National Seed Programme Centers was studied against commonly used insecticides viz., malathion, dichlorvos and deltamethrin. Insects from different populations were found to be susceptible to deltamethrin. Toxicity of malathion was decreased to some populations of C. maculatus. All populations showed highest susceptibility for deltamethrin and least to dichlorvos.
