Restoration of pyrethroid susceptibility in a highly resistant Aedes aegypti population

Insecticide resistance has evolved in disease vectors worldwide, creating the urgent need to either develop new control methods or restore insecticide susceptibility to regain the use of existing tools. Here we show that phenotypic susceptibility can be restored in a highly resistant field-derived strain of Aedes aegypti in only ten generations through rearing them in the absence of insecticide.
