Study finds three mosquito species prefer different people

Study finds three mosquito species prefer different people

Researchers at Florida International University tested 119 volunteers against three disease-carrying mosquito species.

They found that each species preferred different people, and no volunteer attracted all three.

The species included mosquitoes that spread dengue, Zika, yellow fever and West Nile virus.

Aedes aegypti was drawn to people with no added fragrance and certain skin-chemical patterns, while Aedes albopictus responded to other skin chemicals.

The night-feeding Culex quinquefasciatus was more strongly influenced by differences in the skin microbiome, the community of microorganisms living on skin.

The findings suggest mosquito attraction depends on species-specific scent cues, rather than some people being universally attractive to mosquitoes.

Researchers say identifying these cues could help develop repellents tailored to particular species, but further research is needed before that becomes effective protection.

We didn’t expect the species to prefer different people when we started the study.

Each species having a distinct microbial signature that they use as a cue was so surprising to me.

Matthew DeGennaroNeurogeneticist and research team leader
It is clear to me now that our skin microbiomes define our human odor signature. Each species found its own way to decode that signature.

Isolating the components of human odor that attract or repel mosquitoes could lead to novel strategies to combat vector-borne diseases.
