The experiment were conducted on efficacy of biopesticides and certain chemical insecticides against mustard aphid (Lipaphis erysimi Kalt) at research farm Department of Entomology, SHIATS Allahabad during Rabi season of 2012-2015. Result showed that significantly higher seed yield and net return were recorded with spraying of dimethoate 30 EC followed by malathion 50 EC and neem oil (0.5%), respectively. The cost benefit ratio descending order was dimethoate 30 EC > malathion 50 EC > NSKE > Bacillus thuringiensis > neem oil > Beauveria bassiana> Metarhizium anisopliae > Verticillium lecanii> tobacco leaf extract.
