The comparative insecticide efficiency tests of saturated ethanol and acetonic extracts from leaves of Mitracarpus scaber Zuccarini (Rubiale: Rubiaceae) and Phillanthus amarus Schum and Thonn (Euphorbiale: Euphorbiaceae) against four (4) stored food insect pests showed for the first time that the extracts from Mitracarpus scaber are significantly toxic for Cryptolestes sp, (Coleoptera: Cucujidae), Palorus subdepressus Wollaston (Coleoptera: Tenebrionidae), and Rhyzopertha dominica Fabricius (Coleoptera : Bostrichidae). However, no toxic impact from the two plant extracts has been observed in regard to Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae).
