The Pulse beetle Callosobruchus maculatus 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. In the present study, Ether 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., 0.22% G.S.E. The dosages of plant based toxicants (Ether extracts) were found out to give minimum 100% mortality of Callosobruchus maculatus.
