West Nile virus (WN virus) is one of the most widespread arbovirus and exhibits a great genetic diversity with 8 lineages, at least 4 (1, 2, Koutango, putative new) are present in Africa. In Africa, Culex neavei quinquefasciatus considered as potential vectors for WN transmission sylvatic or urban context. We analyzed vector competence these species from Senegal African lineages envelope proteins sequences viral strains used. showed that lineage 1 transmitted by both mosquitoes , whereas new only Cx. . Our findings suggest variability can affect depend on mosquito. However, when considering infective life rate, mosquito population seems to be inefficient field could explain low impact
