what does science say about it

Genetic factors, body odor and carbon dioxide among clues as to why some people are more attractive to mosquitoes

Mosquitoes are considered one of the most annoying and dangerous insects on the planet. Besides the discomfort their bites cause, they also carry serious diseases such as dengue, Zika and malaria. responsible for more than 700,000 deaths annually according to the World Health Organization (WHO). However, many people wonder why these little insects favor some people more than others. What factors determine whether a person is more susceptible to mosquito bites? Science has tried to answer this question, and although there is no definitive answer, several studies have shed light on this phenomenon. showing that both genetic and environmental factors play key roles.

Key Factors Determining the Attractiveness of Mosquitoes

One of the main points of the study was blood type. It has been suggested that mosquitoes may prefer certain blood types over others. In fact, a 2019 study found that Aedes mosquitoes, which carry the dengue virus, showed greater attraction to people with the first blood group compared to other blood groups. However, additional studies have shown conflicting results, making a definitive conclusion difficult. In addition to blood type, other factors also have a greater influence on mosquito preferences.

The role of carbon dioxide (CO₂)

Mosquitoes, especially females, They focus mainly on carbon dioxide, which we emit when we breathe.. Females use this gas as a key signal to locate their prey, as they need a “blood meal” to obtain the necessary proteins to produce eggs. People exhaling more CO₂as well as those with a higher metabolism are more attractive to mosquitoes. Activities such as exercise, drinking alcohol and pregnancy increase carbon dioxide production. increasing the likelihood of getting more bites.

Skin microbiota

Human skin is inhabited by a rich community of microorganisms, the so-called skin microbiota. These microorganisms interact with our sweat and other chemicals on our skin.producing odors that mosquitoes can smell through their antennae and palps. Some studies have shown that certain microbiota compositions may cause a person to emit odors that are more attractive to mosquitoesalthough more research is needed to fully understand this mechanism.

Genetics and twin research

An interesting aspect that has emerged from mosquito research is that the role that genetics plays in attraction to these insects. A 2015 study involving identical and fraternal twins found that 67% of mosquito attraction may be due to genetic factors. In this experiment, identical twins, who share the same genetic material, showed similar levels of attraction to mosquitoes compared to fraternal twins, suggesting that predisposition to stinging has a strong genetic basis.

Other influencing factors

Body colors and warmth

Mosquitoes also respond to visual and temperature cues. Colors like red, orange and black have been proven to be more attractive. for these insects. Additionally, body heat is another important factor. People who emit the most heat Whether due to environmental conditions or their own metabolism, they tend to attract more mosquitoes.

Metabolism and chemicals in the skin

Lactic acid, ammonia and other compounds released in sweat are also attractive to mosquitoes. People who produce more of these chemicals like athletes after intense physical activity, become a more tempting target. In fact, a combination of metabolic factors and chemicals in the skin may be as important as genetic factors.

What can we do to avoid being bitten?

Although many of the factors that attract mosquitoes are beyond our control, experts recommend several measures to reduce the risk of mosquito bites. Using repellents containing active ingredients such as DEET. or eucalyptus-lemon oil has proven to be highly effective. Also recommended wear light clothes and cover as much skin as possible, especially in areas with high mosquito populations. Except, protect the environment from stagnant water This helps reduce the mosquito population as these insects lay their eggs in the water.

Mosquito bites and other oddities

Mosquito bites are not only annoying, but also annoying. They remind us how fascinating the animal world is. Like mosquitoes, there are other curious phenomena in nature and science that deserve attention. For example, did you know that there are six animals created by man in a laboratory? It’s amazing how biotechnology has advanced to this point. On the other hand, if you’ve ever wondered how many people die from shark attacks around the world each year, you might be surprised by the statistics. Not only that, but it is also interesting to know how dogs see and how people can learn how their vision works.An aspect that always surprises among animal lovers.
