Phenotypic and genotypic pyrethroid resistance ofAedes albopictus, with focus on the 2017 chikungunya outbreak in Italy

BACKGROUND The highly invasive mosquito species Aedes albopictus has become a major health concern in temperate areas due to its role as vector of exotic arboviruses. Pyrethroid insecticides represent the main tools for limiting the circulation of such mosquito‐borne viruses. The present work aim to extend previous reports on phenotypic pyrethroid‐resistance in European Ae. albopictus , to identify its genetic basis and to monitor the...
