Recently, as the temperature rises, “buzzing” mosquitoes have also begun to appear. As long as the skin is bare, it will bulge out big red and itchy bumps due to mosquito bites. Mosquitoes are also carriers of many viruses, such as Aedes aegypti, which carries viruses such as chikungunya, dengue, Zika, and yellow fever. So how do mosquitoes accurately find humans? Recently, an international research team led by Princeton University in the United States has found the answer. The findings have been published in the journal Nature. Human scent is made up of dozens of different compounds, and these same compounds are present in varying proportions in most mammals. Mosquitoes are not interested in these compounds themselves, they use these compounds to mix in exact ratios to form specific smells and pinpoint humans. The researchers found through experiments that the two chemicals, decanal and undecal, are the key to detection in the mosquito brain, and the odor produced in a certain proportion is very attractive to mosquitoes and is also unique to humans. The team has patented a decanal-rich mixture that they hope will induce mosquitoes into lethal .
