Research shows combination of sensory signals draw mosquitoes in for a bite

Researchers used a genome editing technique to engineer a mutant version of the Aedes aegypti mosquito, which spreads yellow fever. The mutant was unable to detect carbon dioxide, and studies showed that this hindered its ability to detect a host, even in the presence of other sensory cues like heat and odor. The results can help inform the design of chemical repellents to block host-seeking behavior in both Aedes aegypti and Anopheles gambiae, which spreads malaria. More »

Mutant mosquitoes lose their appetite for humans

Scientists in Leslie Vosshall’s Laboratory of Neurogenetics and Behavior at Rockefeller used a genetically modified mosquito to show that a specific gene called orco gives the insects a strong preference for humans over other mammals, and that the insect repellant DEET uses this pathway to deter mosquitoes from biting.
