Dans le but de réduire l’impact environnemental des produits synthétiques, le potentiel insecticide des fruits verts du poivre de singe fractionnés dans des solvants de polarité croissante a été étudié. Il s’agissait de l’hexane, de l’éther éthylique et de l’éthanol à 70 %. Les extraits ont été élaborés à partir de l’extraction du fruit déshydraté dans chaque solvant. Parmi ceux-ci, cinq doses (10 mg, 20 mg, 50 mg, 150 mg et 250 mg) ont été ajoutées à 100 g de régime alimentaire artificiel de Bowling et proposées à des larves de la chenille du maïs. Le plan expérimental utilisé était entièrement aléatoire et les traitements ont été analysés à l’aide du test de Kruskal-Wallis. Le témoin était le régime de Bowling sans extrait. Chaque traitement était composé d’une dose d’extrait de graine ou de pulpe, avec cinq répétitions, soit quatre parcelles chacune. Les résultats ont confirmé le pouvoir insecticide de la plante étudiée.
