This study was designed to evaluate the toxicity of three insecticides: viz. cypermethrin, azadirachtin and bifenthrin against two important crop infest aphid species Lipaphis erysimi (Katenbach) and Myzus persicae (Sulzer), reared on cauliflower and potato plants respectively. By brining leaves with tested aphid population of the vegetable plants,
residual film technique (RFT) was applied. Cypermethrin was found to be most toxic with LC50 as 14.30 µg cm-2 for L.erysimi and 14.12 µg cm-2 for M. persicae. Bifenthrin showed moderate toxic with LC50 as 28.55 µg cm-2 for L. erysimi and 29.22 µg cm-2 for M. persicae. Among insecticides, azadirachtin showed highest toxicity with LC50 as 0.33 µg cm2 for L. erysimi and 0.31 µg cm-2 for M. persicae
