Selective targeting of biting females to control mosquito-borne infectious diseases

B. B. Kojin, A. Compton, Z. N. Adelman and Z. Tu,  Trends in Parasitology,  2022.
Mosquitoes are vectors for a number of infectious diseases. Only females feed on blood to provision for their embryos and, in doing so, transmit pathogens to the associated vertebrate hosts. Therefore, sex is an important phenotype in the context of genetic control programs, both ...
