Effect of agro-ecological zones and contiguous basin crops of groundnut (Arachis hypogaea) on the structuring and genetic diversity of Caryedon serratus (Coleoptera: Chrysomelidae, Bruchinae) in the sub-region of West Africa

► Important gene flow between the agro-ecological zones ► Gene flow not observed between the basin of culture and areas out of culture ► We have no genetic differentiation according to agro-ecological zones. ► Differentiation between individuals from pools of culture and out of culture
