A laboratory trial was conducted to determine the relative toxicity of various insecticides against larvae of Spodoptera litura on cabbage. The bio-efficacy of various insecticides against larvae of S. litura revealed that higher larval mortality by leaf dip method was recorded in the treatment with spinosad 45 SC @ 0.025 per cent (87.49%). The second effective treatment was profenophos 40 % + cypermethrin 4% @ 0.017 per cent (80.49%) which was also superior over rest of the treatments except spinosad 45 SC @ 0.025 per cent. The bio-efficacy of various insecticides against larvae of S. litura revealed that the higher larval mortality by topical application was recorded in the treatment with emamectin benzoate 5 SG @ 0.025 per cent, which gave the maximum 90.50 per cent mortality and it was at par with spinosad 45 SC @ 0.025 per cent (87.49%).
