To determine the insecticidal properties of neem saw dust on Callosobruchus chinensis L. in laboratory condition. An experiment was set in Zoology Research Laboratory, D.A-V College, Kanpur, India. Different doses of neem saw dust i.e., 200, 400, 600 and 800 mg along with control in three replications per 100 g of chickpea seeds was set and 25 pairs of C. chinensis were introduced in each jar and kept at 28±2°C. Observations on percentage of damaged seeds and population of insects were recorded during summer, rainy and winter seasons. The results showed significant reduction in damage as well as in the insect population. The treatment containing 800 mg/100 g showed highest toxicity and treatment containing 100 mg showed least damage.
