Experiments were conducted to control Callosobruchus maculatus (Fab.)  infesting the stored cowpea seeds. In the present study, Ether Extracts of Neem seed kernel (N.S.K.E.) and Black Pepper seeds (B.P.S.E.) were found toxic against Callosobruchus maculatus in stored cowpea seeds. Thus, the study was aimed at the search of eco­friendly pesticides in Neem Seed Kernel and Black pepper seed Extracts in Ether at minimum 100% and 50% mortalities.  0.06% N.S.K.E. in Ether at minimum 100% mortality was found effective for 75 days while 0.02% N.S. K. E. in Ether causing about 50% mortality of Callosobruchus maculatus was found effective for 60 days. 0.18% B.P.S.E in Ether at minimum 100% mortality was found effective for 60 days while 0.07% B.P.S.E. in Ether causing 50% mortality of Callosobruchus maculatus was found effective for 45 days.
