Mosquitoes are quite annoying creatures, especially during the summer periods, before or while sleeping. Hiding from a mosquito is also close to impossible, because they find people by monitoring breathing, body temperature, body odor. Some people argue that even though they are in the same house, mosquitoes only bite them. And the argument is not empty. Previously, different theories were trying to explain this situation, including blood cluster, blood sugar level, consuming garlic or banana, being a woman and a child. But Leslie Vosshall, leader of Rockefeller’s Neurogenetics and Behavior Lab, says that’s too little credible information for more than one, but now a new study says that some people really are “mosquito magnets,” and it’s probably related to the way they smell.
WHAT ATTRATES Mosquitoes?
Previously, there were different arguments about who the mosquitoes most prefer to bite. But many of them were not scientifically proven.
So what does the new study say?
According to a study by a research group from Rockefeller University in New York, people who attract mosquitoes the most have high levels of skin. producing carboxylic acidpeople.
Within the scope of the study, 64 volunteers were asked to wear nylon sleeves on their arms. The three-year study used human forearm odor samples collected from these nylon sleeves and performed more than 2,330 tests over 174 days.
Aedes aegypti mosquito, which can spread viruses such as yellow fever and Zika, was used in the tests. There was a 100-fold difference between the subjects that attracted the most mosquitoes and those that attracted the least.
Vosshall says he expects similar results from other cultivars, but more research is needed to confirm this.
Researchers found a common factor amid favorites: Mosquito magnets had high levels of carboxylic acids in their skin . These oily molecules that attract mosquitoes are actually a part of the skin’s natural moisturizing layer. Human bodies produce this at different levels. Healthy bacteria living on the skin consume these acids and form part of the skin’s odor profile.
DIFFICULT TO STOP Mosquitoes
Humans produce the two most important classes of odors that mosquitoes detect with two different sets of odor receptors: Orco and IR receptors. Scientists also tested whether they could breed mosquitoes that could not detect humans. Researchers from buyers They created mutants in which one or both were missing. Orco mutants continued to be attracted to humans, and they went back to ‘mosquito magnets’. IR mutants lost interest in humans to varying degrees, but still retained their ability to find humans.
The research says: These were not the results scientists had hoped for. “The target was a mosquito that would lose all appeal to humans, or a mosquito with a weak attraction to everyone. That would be great for more effective mosquito repellents. But it wasn’t expected,” says Vosshall.
Vosshall emphasizes the resilience of mosquitoes for this situation and states that they always have a backup plan.
