Abstract
The antifeedant potential of extracts of five natural plants; Galic (Allium sativum), Manjack (Cordia millenii), African nutmeg (Mondora myristica), Negro pepper (Xylopia aethiopica) and Ginger (Zingiber officinale) against cowpea weevil, (Callosobruchus maculatus) was evaluated. The results established that extracts of Ginger caused the strongest feeding deterrency against the insect pests with percentage feeding index of 48.3%. The order of the antifeedant potency of the extracts against C. maculatus after 5-hour exposure was Z. officinale (43.9%), > X aethiopica (48.3%) > C. millenii (59.9%) > A. sativum (61.6%) > M. myristica (64.9%). The study further discussed the challenges confronting researchers and farmers in practically deploying these plant materials for general use in crop protection and makes recommendations on appropriate solutions.
