An investigationwas carried out to assess the efficacy of insecticides by leaf disc bioassaymethod using various chemical components, neem oil and some other biopesticidesagainst shoot and leaf webber, Antigastra catalaunalis during 2011-12 inKaraikal district, U.T. of Puducherry. In the leaf disc bioassay method againstA. catalaunalis, it was found that the per cent larval mortality in the treatmentwith lambda cyhalothrin 5 EC @ 25 g a.i./ha was high after 6,12,18 and 24 hours(13.33, 40.00, 73.33 99.99%) followed by spinosad 45 SC @ 33.75 g a.i./ha(13.33, 33.33, 60.00 and 99.99%), Bacillus thuringiensis var. kurstaki@ 50 g a.i./ha (6.66, 26.66, 53.33, 66.67,76.67%) over the untreated check.
