High voltage-gated sodium channel gene diversity in Aedes albopictus across Brazil.

ABSTRACT: The invasive Aedes albopictus, commonly known as the Asian tiger mosquito, has spread globally, posing public health risks because of its role as a secondary vector for arboviruses and capacity to transmit pathogens across sylvatic and urban cycles. In Brazil, where Ae. aegypti remains the primary vector of dengue, Zika, and chikungunya viruses; Ae. albopictus is being increasingly monitored because of its ecological plasticity and potential to develop insecticide resistance. Here, we analyzed the genetic diversity of voltage-gated sodium channel (Na_V) gene in Ae. albopictus populations across Brazil, in which knockdown resistance mutations (kdr) are associated with pyrethroid resistance. We collected Ae. albopictus from 46 Brazilian cities, extracted DNA from individual mosquit
