Identification and characterisation of Aedes aegypti aldehyde dehydrogenases involved in pyrethroid metabolism
Background: Pyrethroid insecticides, especially permethrin and deltamethrin, have been used extensively worldwide for mosquito control. However, insecticide resistance can spread through a population very rapidly under strong selection pressure from insecticide use. The upregulation of aldehyde dehy...
