Antifeedant Potential of Some Aromatic Plants Against Cowpea Weevil, Callosobruchus Maculatus
Authored by Egwunyenga Ogochukwu Andy
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.
