One of the most vilified pest species on the planet continues to outsmart the ways in which humans attempt to get rid of them.
"Super" mosquitoes have evolved to withstand insecticides, according to new research -- and the most "sobering" finding is the high rate in which a species known for carrying disease has developed mutations.
Researchers at the National Institute of Infectious Diseases in Japan studied mosquitoes in dengue-endemic areas in Vietnam and Cambodia and found that they harbor mutations that endow them with strong resistance to common insecticides, according to a study published in Science Advances on Wednesday.
One of the most concerning mutations appeared in about 78% in collected specimens of Aedes aegypti -- one of the most infamous species of mosquito and a major vector of dengue, yellow fever and Zika virus, according to the study.
veloping resistance pyrethroids often occurs when mutations appear in the Vgsc gene, which encodes the molecular target of pyrethroids, the paper states. The researchers discovered 10 new sub-strains of Ae. aegypti and noticed that one Vgsc mutation -- called L982W -- endowed mosquitoes with high resistance to the pyrethroid insecticide permethrin in the lab.
