Comparison of the Insecticidal Activities of Three Plants against Two Devastating Insects: Callosobruchus maculatus and Sitophilus zeamais

Abstract

To find the alternate ones with insecticides of synthesis, the extracts of plants are more and more used by the peasants to protect stocks from harvest against the devastating insects. Small fireclay cups phytochimic and insecticidal are made on three plants (Crataeva religiosa, Ficus thonningii and Tapinanthus bangwensis). The identification of the active ingredients present in the three plants show that they contain polyphenols, flavonoides, alkaloids, tannins, saponosides, etc. The insecticidal tests How to cite this paper: Diouf, E.H.G.,

Efficacy of Aromatic and Medicinal Plant Powders against Callosobruchus maculatus F. (Chrysomelidae: Bruchinae)

“…Various studies have demonstrated the efficacy of several plants as protective agents. [12][13][14][15] Piper nigrum powder (Piperaceae) has caused a significant reduction in the bruchids population in cowpea stocks, 16 and similar results were obtained with Neem powder (Azadirachta indica A. Juss). 17 Essential oils of Ocimum gratissimum L, and Ocimum basilicum L. have been successfully used against C. maculatus.…”

Screening of Vegetable Powders Used as a Bio-Insecticide Against Callosobruchus Maculatus F. (Chrysomelidae: Bruchinae)

“…Recent research has focused on alternatives to chemicals for pest control in developing countries. Various studies have demonstrated the efficacy of several plants as protective agents (Pannuti et al 2012;Tamgno and Tinkeu 2014;Nenaah 2014;Diouf et al 2016). Piper nigrum powder (Piperaceae) has caused a significant reduction in the bruchids population in cowpea stocks (Nwosu et al 2018), and similar results were obtained with Neem powder (Azadirachta indica A. Juss) (Neto et al 2019).…”
