Researchers master gene editing technique in mosquito that transmits deadly diseases

Researchers master gene editing technique in mosquito that transmits deadly diseasesRockefeller University researchers have successfully harnessed a technique, CRISPR-Cas9 editing, to use in an important and understudied species: the mosquito, Aedes aegypti, which infects hundreds of millions of people annually with the deadly diseases chikungunya, yellow fever, and dengue fever.

Research suggests how mosquitoes evolved an attraction to human scent

Research suggests how mosquitoes evolved an attraction to human scentTo understand the evolutionary basis of the mosquito’s attraction to humans, scientists examined the genes that drive preferences of two different subspecies. Their findings suggest that Aedes aegypti aegypti acquired a love for human body odor, a key step in specializing on people. More »

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 »
