Abstract: An investigation was carried out to study the insecticidal management of whitefly (Bemisia tabaci Gennadius) in brinjal during Kharif 2015 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Efficacy of different newer insecticides viz., thiamethoxam 25 WG, imidacloprid 17.8 SL, acephate 20 SP, fipronil 5 SC, thiacloprid 240 SC and one conventional insecticide i.e. dimethoate 30 EC were evaluated against Bemisia tabaci revealed that thiamethoxam 25 WG @ 100g/ha was found most effective insecticide in reducing the population of whitefly followed by imidacloprid 17.8 SL @ 100 ml/ha. Dimethoate 30 EC @ 500 ml/ha was recorded less effective to reduce the white fly population. The highest fruit yield (127.05 q/ha) was obtained from thiamethoxam whereas higher cost benefit ratio (1:12.90) was obtained from treatment imidacloprid. The next highest fruit yield (126.14 q/ha) and cost benefit ratio (1:12.62) were obtained from imidacloprid and thiamethoxam, respectively. The lowest yield (117.43 q/ha) and cost benefit ratio (1:5.50) were obtained from the treatment dimethoate and thiacloprid, respectively.
