The research paper mainly describes the concepts and Biocontrol measures to control Callosobruchus maculatus (Fab.) in stored Cowpea Seeds. The pulse beetle Callosobruchus maculatus (Fab.) is an obnoxious pest of several pulses including cowpea.  Hence the present study is aimed at the search of an eco-friendly pesticide e.g. neem seed kernel extracts against Callosobruchus maculatus. It has been estimated that 0.06% and 0.02% concentrations of neem seed kernel extracts in ether and alcohol were effective for a greater period of storage against bruchid attack. 0.06% concentration of ether extract and alcoholic extract of neem seed kernel were found effective for more than 75 days while 0.02% concentration of ether and alcoholic extracts were effective for up to around 60 days after treatment against Callosobruchus maculatus. Ether extracts in both concentrations were however found somewhat more effective in comparison to alcoholic extracts of NSKE.
