the lepidopterous pest viz., Helicoverpa armigera (hubner) passed through two generations while, Amsacta moorie (buttler), passed through one generation each during summer. the highest larval mortality of H. armigera during its two generations in a year was recorded due to unknown reason (13.15 per cent) followed by nuclear polyhydrosis virus (7.60 per cent) and an unidentified parasitoid (6.81 per cent). The egg sterility was observed to be 13.14 per cent and its pupal mortality was due to unknown reason (9.91 per cent). the highest larval mortality of A. moorie was recorded due to unknown reason (13.97 per cent) followed by egg sterility (13.33 per cent) and pupal mortality due to unknown reason (13.15 per cent).
