Abstract

Caryedon serratus is found in different agro-ecological and agro-climatic zones, and its damage to groundnuts can vary up to an 80% quantitative loss of yield. This study seeks to demonstrate the effects of different agro-ecological refer to so as to very quickly process the content zones and the presence or absence of groundnut cultivation on the structure and genetic distribution of C. serratus in West Africa. Portions of the cytochrome b and 28S ribosomal genes of C. serratus were sequenced, using samples from four countries that represent different agro-ecological and agro-climatic sub-region of West Africa. The results showed 37 haplotypes for the cytochrome b and 7 haplotypes for the 28S ribosomal gene. Although genetic diversity was different between agro-ecological zones tests show no significant differences in structuring according to agro-ecological zone. These tests, as well as the phylogenetic relationships that our results imply, indicate that there is genetic differentiation between individuals from groundnut culturing areas compared to those from areas where the cultivation of groundnuts is absent or low.
