Transcriptomic and proteomic analysis of pyrethroid resistance in the CKR strain of Aedes aegypti.

Aedes aegypti is an important vector of human viral diseases. This mosquito is distributed globally and thrives in urban environments, making it a serious risk to human health. Pyrethroid insecticides have been the mainstay for control of adult A. aegypti for decades, but resistance has evolved, mak...
