Abstract: A field experiment was conducted during kharif 2016, at College of Agriculture, V. C. Farm, Mandya to know the influence of abiotic factors on the population fluctuation of sesame leaf webber and capsule borer, Antigastra catalaunalis. During summer 2016, the population of leaf webber and capsule borer, A. catalaunalis exerted a negative association with morning relative humidity (r = -0.22) and sunshine hours (r = -0.64**) and the population exerted positive association with maximum temperature (r = 0.41), minimum temperature (r = 0.01) and afternoon relative humidity (r = 0.52). The combined and overall impact of all the significant abiotic factors on leaf webber and capsule borer populations were to the extent of 79.00 (R2 = 0.79), per cent. Similarly, during kharif 2016, the sunshine hours showed a significant negative correlation with population of leaf webber and capsule borer. The combined and overall impact of all the significant abiotic factors on leaf webber and capsule borer, populations were to the extent of 32.00 (R2 = 0.32), per cent.
