An experiment was carried out to evaluate the efficacy of integrated management practices over farmers’ practices against insect pest complex of green gram (Vigna radiata L. Wilczek) during kharif season in the ‘A-B’ Block Farm of Bidhan Chandra Krishi Viswavidyalaya in 2019. The results revealed that the incidence of all of the insect pests viz. whitefly, pulse aphid, jassid, flower thrips, gram pod borer, spotted pod borer, blue butterfly, plant bug and pod bug was recorded comparatively less in Integrated Pest Management (IPM) plot as compared to farmers’ practices. The seed yield of green gram was also recorded a higher (1382.22 kg ha-1) in plots treated with integrated approaches as compared to farmer’s practices (476.94 kg ha-1). IPM module recorded maximum cost benefit ratio along with higher gross return and net profit as against farmers’ practices.
