Table 3.
ace-1R G119S mutation frequency of An. gambiae (s.l.) from Bouaké and association with phenotypic resistance from carbamate bioassays. Superscript a and b show a significant difference between alive and dead within the same population on a site (P < 0.05). Frequencies were not calculated when the number of individuals tested was low (−)
