WEB DESK: Although these are tiny creatures but they are extremely irritating and gross.
Moreover, even if you bathed well and make it sure that you shut all the windows and doors to impede them from entering in the house, you will still find one irritating mosquito. How could this happen ? There’s a scientific reason behind it.
According to scientists, mosquitoes are attracted by certain DNA.
A research has been done by researchers of London in to figure out genetic role in these mosquitoes attraction by checking the bite appeal of female twin in which 18 were identical and 19 were fraternal. They carried out the investigation in a series of tests, 20 hungry mosquitoes were released into the end of a Y-shaped tube and allowed to choose whether to follow their noses left or right. Down either path was one twin’s hand, releasing its delicious natural odors but protected from bites behind a mesh screen. After testing all 37 twin pairs, scientists found that the identical twins had consistently more similar attraction scores than the fraternal ones did—specifically, 67 percent of a person’s insect attractiveness had to do with her genes.
The question arises that does DNA stink ? No, but certain DNA attract unique species of microbacteria to human body which is what more appealing to tiny, irritating mosquitoes.
The research further states, each of us, right now, is covered with about 100 trillion microbes, outnumbering our human DNA ten to one. Maybe weirder still: Scientists believe we share only a fraction of these microbial species with one another, making our “microbiome”—the world of bacteria living in and on us—unique, just like our fingerprints. In addition to producing many of the vitamins and chemicals in our blood, our microbiome is thought to be responsible for most of our distinct odors as well.
It is note worthy here that different mosquitoes prefer different smells from different parts of the body—that’s why Aedes gambiae (known for spreading malaria) prefers biting hands and feet, while others go right for the armpits or groin. And those smells come from chemicals produced by our microbiomes.
