FIU Study of 119 Volunteers Finds Mosquito Species Prefer Different People

Summary
Three major mosquito species did not converge on the same “mosquito magnets” in tests on 119 volunteers, undercutting the idea that one type of person attracts all mosquitoes.
FIU researchers found each species keyed on different scent cues: Aedes aegypti favored unscented people lacking certain volatiles, Aedes albopictus responded to elevated ketones and plant-like compounds, and Culex quinquefasciatus tracked skin-microbiome signals.
More than 1,000 volatile organic compounds can shape human odor, and the team paired preference tests with odor and microbiome sampling to identify which chemicals and bacteria drew or repelled each species.
The findings, published in iScience, suggest repellents and public-health measures may need to be tailored by species for mosquitoes that spread dengue, Zika, yellow fever and West Nile.
