Abstract

Early instar and late instar larvae and pupae of E. atomosa in first and second generations were killed to the tune of 2.19, 4.25 and 10.28 and 2.09, 4.88, and 12.50 per cent, respectively due to unknown causes. In both the generations the maximum contribution towards generation mortality came from pupal stage (K = 0.0471 and 0.0580). the trend indices of E. atomosa infesting pigeonpea were found to be 0.73 in first generation. However, it was zero in second generation of plume moth.
