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).

Plain Language Summary

This study shows, for the first time, that a plant (in this case, a plant from the Ivory Coast) possesses insecticide properties that affect some insects that have harmful effects on the preservation of harvested crops.

The researchers tested two plants, Mitracarpus scaber and Phillanthus amarus, that are known to have medicinal properties. Only the first plant demonstrated insecticide effects on three of the four main pest insects present in food warehouses.

This study is the first step in the identification of biological insecticides produced from plants. The objective is to propose alternatives to synthetic insecticides in order to protect harvested crops.
