Black gram whitefly (Bemisia tabaci) is a significant pest that inflicts substantial yield losses in black gram crops by sap-sucking, inducing yellowing of leaves, and transmitting devastating plant viruses, making its effective management crucial for ensuring crop productivity. The present study was undertaken to determine the bio-efficacy of six insecticides viz., Thiamethoxam 25 WG @ 100 g/ha, Acetamiprid 20 SP @ 100 g/ha, Chlorantraniliprole 18.5 SC @ 150 ml/ha, Imidacloprid 17.8 SL @ 125 ml/ha, Profenofos 50 EC @ 1250 ml/ha and Neem Seed Kernel Extract (NSKE) 5 Per cent @ 25 kg/ha against white fly of black gram crop. All the insecticidal treatments were found significantly superior in reducing the population of white fly as compared to control after 10 days of spray. Among all the treatments, Thiamethoxam 25 WG @ 100 g/ha was found most effective with minimum population (2.87 white fly/5 plant) followed by Acetamiprid 20 SP @ 100 g/ha (3.07 white fly/5 plant).
