Abstract: Callosobruchus maculatus is a serious pest of stored pulses belonging to the order of beetles, Coleoptera hence also called pulse or bean beetle. In the present article, indigenous method of pest control by adopting the products of a pesticidal plant leaf, tobacco (Nicotiana tabacum) has been discussed on the basis of the findings over the natality, mortality & larval growth of pest on stored grams hampered by the tobacco plant extract. A significant result has been obtained by the decreasing trend of population growth of the pest (P> 1.05) thereby encouraging the farmers & stored grain & other product managers to adopt this safe & indigenous method pest control in a low & control dose. As tobacco product is itself very toxic & harmful to the human consumers, higher doses of application should be avoided.
