Insecticide resistance genes affect vector competence for West Nile virus

In a context of overuse of insecticides, which leads to the selection of resistant mosquitoes, it is already known that this resistance to insecticides affects interactions between mosquitoes and the pathogens they transmit. Researchers from the Institut Pasteur (Paris) and its partners prove that mechanisms of insecticide resistance, observed in Culex quinquefasciatusvector, impact the transmission of West Nile virus.
