Petroleum ether extracts of fleabane leaves ['nu/a Conysoides), dill seeds (Anethum graveofens L.) and their powders, also two insecti­cides Neemazal-F (liquid formulation contains 5% Azaderachtin) and Actellic (pirimiphos methyl E.C. 50%) were evaluated for mortality and reduction in Fl progeny against Callosobruchus maculatus F.infesting the cowpea seeds. Results showed that mortality and reduction in Fl progeny were achieved using the extract of fleabane leaves or the dill seeds. Also, powders of the two plant species revealed toxic effect on this pest in­festing the cowpea seeds, but lower mortality values were obtained as well as the reductions in Fl progeny. Reductions in Fl progeny were very high in case of dill seed extracts. The insecticides of Neemazal-F. and Actellic showed high mortali­ties and reduction in Fl progeny. However, Acteliic surpassed Neernazal in its effect against Callosobruchus maculatus F.
