Protease inhibition in cowpea pod-sucking bug species (Hemiptera: Heteroptera) using cereal and legume grain extracts

Selected grain extracts were assayed against digestive proteases of Anoplocnemis curvipes, Clavigralla tomentosicollis and Mirperus jaculus with a view to identifying suitable sources of protease inhibitors against the cowpea pests. Laboratory bioassays showed that grains of a local soybean variety Kìshí and a cowpea landrace NG/SA/07/0098 contain potent inhibitors although the former produced a...
