Table 5 Genotype selection by the single and combination treatments: percentage survival of Anopheles gambiae kdr and ace-1 R genotypes collected from the experimental huts in Tiassalé

From: Combining organophosphate-treated wall linings and long-lasting insecticidal nets fails to provide additional control over long-lasting insecticidal nets alone against multiple insecticide-resistant Anopheles gambiae in Côte d’Ivoire: an experimental hut trial
