Field experiments evaluated the efficacy of insecticides against sesamum shoot webber Antigastra catalaunalis Duponchel. Emamectin benzoate 5 SG @ 200g/ ha recorded minimum damage (1.93% and 1.31%) and larval incidence (1.87 and 2.70/ plant) during kharif and rabi, respectively. Predatory coccinellids and spiders (0.61 and 0.68/ plant), maximum seed yield of 650 kg/ ha and highest B: C ratio of 1:2.49 were obtained with emamectin benzoate 5 SG.
