Experiments were carried out to determine the insecticidal activity of Aegle marmelos Correa against Callosobruchus chinensis L. in the laboratory. Plants were extracted with petroleum ether, methanol, ethanol and water by using Soxhlet apparatus and tested against adult of C. chinensis. Plant extracts were showed insecticidal activity by affecting through mortality, oviposition deterrence and inhibition of F1 adult emergence. Among the solvent extracts petroleum ether was found to be significantly superior over rest of the solvent extracts, registered the highest percent of mortality (82%) at 5% conc. after 96 hour of treatment followed by methanol (80%), ethanol (76%) and water extract (74%) respectively. Highest oviposition deterrence was found in petroleum ether extract (59.74%), followed by methanol (57.32%), ethanol (56.07%) and water extract (55.28%) respectively at 5% conc. after 7days of seed treatment. In terms of inhibition rate, petroleum ether extract at 5% conc. was found to be most effective (75.91%), followed by methanol (74.50%), ethanol (73.87%) and water extract (70.28%) respectively from 1st day to 10th days of adult emergence. The leaf extract at different doses significantly reduced oviposition and adult emergence of C. chinensis in treated green gram seeds.
