Insecticide resistance genes affect vector competence for West Nile virus
Overuse of insecticides, which leads to the selection of resistant mosquitoes, affects interactions between mosquitoes and the pathogens they transmit. Researchers from the Institut Pasteur (Paris) and its partners have now shown that mechanisms of insecticide resistance, observed in Culex quinquefasciatus vector, impact the transmission of West Nile virus. In recent decades, arthropod-borne viruses (arboviruses) […]
