The egg stage in some cases, the most vulnerable, it is probably the least studied in terms of its relative susceptibility. Indeed, in only the most obvious cases the attention been given to control programmes based on attacks in the egg stage. Quite aside from the question of control, the insect egg is of interest as a convenient unit for the study. The sequence of events in embryogenesis provides opportunities for studying the relationship between structure and function and the effect of toxicants on various biochemical systems. The present investigation on effect of HaNPV with biopesticides and chemical insecticides on egg laying of H. armigera (Hubner) on chickpea was carried out in Rabi 2014-2015 at PGI farm Dr. PDKV, Akola. It was found that the mean number of eggs laid by H. armigera on chickpea ranged from to eggs/plant after 3rd day of application whereas it reached to to eggs/plant after 14th day of application. | Effect of HaNPV with biopesticides and chemical insecticides on egg laying of H. armigera (Hubner) on Chickpea
