Tracing temporal and geographic distribution of resistance to pyrethroids in the arboviral vector aedes albopictus
Background The arboviral vector Aedes albopictus became established on all continents except Antarc-tica in the past 50 years. A consequence of its rapid global invasion is the transmission of diseases previously confined to the tropics and subtropics occurring in temperate regions of the world, inc...
