A field experiment on the efficacy of biopesticides and newer insecticides against mustard aphid, Lipaphis erysimi (Kalt.) was conducted during 2016-17 and 2017-18. The treatment dimethoate 30%EC was found to be the most effective followed by pyriproxyfen 10%EC and buprofezin 25%SC. The maximum seed yield was obtained with dimethoate 30%EC (13.31 q ha-1) followed by pyriproxyfen 10%EC (13.07 q ha-1), buprofezin 25%SC (12.83 q ha-1) and pymetrozine 50%WG (11.79 q ha-1). The maximum net return
