Some people seem to attract mosquitoes far more than others, but new research suggests the answer is more complicated than the usual “sweet blood” myth. The latest Europe news on mosquito-borne health risks points to a more precise explanation: different mosquito species appear to prefer different people, based largely on body odour and the microbes living on the skin.
A study published in iScience examined how three mosquito species responded to 119 people in laboratory testing in Miami: Aedes aegypti (yellow-fever mosquito), Aedes albopictus (Asian tiger mosquito) and Culex quinquefasciatus (southern house mosquito). Researchers found that while some participants were highly attractive to more than one species, nobody ranked among the most attractive to all three.
That means being a “mosquito magnet” is not universal. Instead, attraction appears to vary by species, with each insect responding to a distinct mix of chemical cues and skin microbes.
Latest Europe news: what the mosquito study found
Mosquitoes do not rely on a single signal when choosing a host. Scientists say they use a combination of:
- Carbon dioxide from breathing
- Body heat and humidity
- Visual signals
- Human scent, including hundreds of volatile compounds
- Microbes naturally living on the skin
According to the researchers, the yellow-fever mosquito showed a slight preference for male participants and was linked to certain volatile compounds and bacterial patterns. The Asian tiger mosquito was associated with elevated ketones and plant-like compounds released by skin. The southern house mosquito, which is more active at night, appeared to respond strongly to the broader microbial ecosystem on the skin, including bacteria and fungi.
The findings suggest each species may use its own “microbial signature” to identify a preferred host.
Why this matters for Europe news today
This research has particular relevance for Europe news today because not all three species have the same footprint across the continent. The Asian tiger mosquito is already established in many European countries and has expanded across parts of southern, western and central Europe. Public health agencies have repeatedly linked its spread to warmer conditions, global trade and human mobility.
By contrast, the yellow-fever mosquito has a more limited presence in Europe, while the southern house mosquito is generally not established across mainland Europe in the same way.
That makes the Asian tiger mosquito especially important for European current affairs in health and climate policy, because it can carry diseases including dengue, chikungunya and Zika. As climate patterns shift, mosquito surveillance is becoming a broader European public health issue rather than a purely tropical concern.
What the findings could mean for disease prevention
Scientists say understanding which compounds attract or repel different species could help shape more targeted prevention tools. In time, that could support:
- More effective repellents tailored to specific mosquito species
- Better public health monitoring in higher-risk regions
- Improved guidance for people especially vulnerable to bites
- New strategies to reduce the spread of mosquito-borne disease
Still, the researchers caution that the work was done under laboratory conditions. It does not prove that the same people would receive more bites outdoors, where wind, clothing, movement and environment also affect mosquito behaviour.
Field studies will be needed before the results can be translated into public health recommendations.
The takeaway
The latest Europe news from health research shows mosquitoes are far more selective than many people assume. Different species appear to favour different human scent and skin-microbe profiles, a finding that could eventually improve prevention of mosquito-borne disease in Europe as invasive species continue to spread.
