Multiple-Insecticide Resistance in<i>Anopheles gambiae</i>Mosquitoes, Southern Côte d’Ivoire

Abstract

Malaria control depends on mosquito susceptibility to insecticides. We tested Anopheles gambiae mosquitoes from Côte d'Ivoire for resistance and screened a subset for target site mutations. Mosquitoes were resistant to insecticides of all approved classes. Such complete resistance, which includes exceptionally strong phenotypes, presents a major threat to malaria control.
