Incidence and Avoidable Loss due to Leaf Roller/Capsule Borer, Antigastra catalaunalis Dup. in Sesame Gupta M.P., Rai H.S., Chaurasia S.K. I.N.K.V.V. Zonal Agricultural Research Station, Tikamgarh 472 001, India. Abstract Grain yield loss due to the incidence of leaf roller/capsule borer, Antigastra catalaunalis was assessed in sixteen varieties of sesame during twelve kharifseasons of 1986 to 1988. Three sprays of 0.07% endosulfan significantly reduced capsule damage caused by Antigastra larvae and also. increased the grain yield in all the sixteen varieties during the seasons of their testing. Mean avoidable loss in grain yield ranged 6.2 to 43.1% being 6.2% in Imp.sel-5; 9.4% in CT-785; 19.2–24.9% in TC-25; 22.5% in RT-46; 25% in JLT-26; 27.2% in RT-54; 32.7% in TKG-55; 34.5% in TKG-21; 34.7% in TKG-22; 35.0% in N-32; 41.0% in Rauss-17-4; 41.6% in JTS-8; 41.7% in RT-125; 42.2% in TKG-67; 42.7% in TKG-117 and 26.8–43.1% in JT-7.
