Abstract: Storing the grains is a traditional practice which includes different storage structures providing aeration and protection from pest and diseases with the assurance of grain quality. Insect pests are one of the important constrains for maintaining quantity and quality of the grains in storage. Pesticides are one of the management practices for storage pests which may brought changing behavior of insects towards the chemical molecule and also to made the grains unfit for consumption with more residues. It is necessary to find out alternative control measures and the plant derivatives are the best choice because of their efficacy and safety to environment. E. hirta leaves were collected, dried and made into solvent extraction by using different solvents. The pulse beetle C. maculatus was exposed at different concentration viz., 1%, 5%, 10%, 15% and 20% of different solvent extracts and mortality was observed on 12, 24, 36, 48, 60 and 72 hrs after treatment. All the solvent extracts shown more than 50% mortality of C. maculatus at 15% concentration. Among which methanol ranked first with the mortality of 66.04%.
