The Research paper mainly describes the concepts of Biocontrol measures to control Callosobruchusmaculatus (Fab.) in stored cowpea seeds. Cowpea is an important legume crop growing across the word mainly in typically, chemical fertilizers are used to handle this issue but try are expensive and have deleterious implications on the ecosystem. Cowpea serving multiple roles for many low- income farmers. However, its productivity remain low and discrepancies exist in selection and acceptability criteria.In stored grain insects are cause serious loss of stored pulses and degrade the nutritional value of pulses. Some plant products are active against specific target insects. The pulse beetle Callosobruchusmaculatus is an obnoxious pest of several pulses and cereals which constitute the major portion of human diet. Pulses are the most important source of protein.  The present study is aimed at the search of some Eco-Friendly pesticides. Alcoholic extracts of Neem seed kernel, Mustard seed, Black pepper seed, Annona seed and Groundnut seed were not found to impair the germination capacity of cowpea seeds at the dosages of 0.06% (N.S.K.E.) 0.16% (M.S.E.) 0.18% (B.P.S.E.) 0.20% (A.S.E.) and 0.22% (G.S.E.) The dosages of plant-based toxicants (Alcoholic Extracts) were found effective to give minimum 100% mortality of Callosobruchusmaculatus.
