Abstract: Investigations on “Efficacy of Different insecticides Against Leaf and Capsule Borer, Antigastra catalaunalis (Dup.) Infesting Sesame, Sesamum indicum (Linn.).” were conducted at Agronomy farm and Department of Entomology, S.K.N. College of Agriculture, Jobner during Kharif, 2015 and 2016. A. catalaunalis were recorded as major insect pests of sesame during both the years of study. Total nine treatments including untreated control were tested against A. catalaunalis for their efficacy. The insecticides viz., spinosad and indoxacarb followed by acephate and standard check (carbaryl) were found most effective, whereas, the entomopathogenic fungus, B. bassiana and NSKE were found least effective against the pest. The highest seed yield of 8.22, 8.16, 7.85 and 7.59 q ha^-1 was recorded in the plots treated with spinosad, indoxacarb, acephate and carbaryl, respectively. The highest B: C ratio was recorded in acephate (11.61), followed by vertimec (11.37) and carbaryl (9.43).
