Capsicum annum and Capsicum frutescens fruit and seed powders were evaluated in the laboratory for the control of Callosobruchus maculatus (F.) in stored cowpea and Sitophilus zeamais Motschulsky in stored maize. Capsicum frutescens seed powder and Capsicum annum seed powder dust were toxic to C. maculatus and S .zeamais at the rate of 5.0g, 7.5g and 5.0g, per 50g cowpea and 50g maize within 48hrs and 96hrs respectively. This paper highlights the potential of C. frutescens and C. annum seed powders as seed protectants against the test bruhids at higher rates, than their ineffective fruit powders in all parameters assessed
