From perfume, towards the color of your shirt, right down to the smelliness of the feet, mosquitoes appear to find any reason to sink themselves into human skin.
Scientists claim that stinky feet and socks can be added to the list of factors that attract 腳臭 to feed off human blood. One African scientist is currently using that little research to help you fight malaria in Tanzania by creating traps that provide off, seeking to lure the bloodsuckers that carry the ailment to their hosts.
“Scientists have known for some time that mosquitoes smell people; that they can do not see us, but rather they smell us,” wrote Dr. Fredros Okumu in a email from Tanzania where he heads the studies project at the Ifakara Health Institute. “This is basically the things that we produce in your breath, sweat of skin that [mosquitoes] use like a signal to find us. If you are wearing socks, these skin-derived chemicals remain on the sock fabric and can nonetheless be detected by mosquitoes even once you have removed your socks.”
Okumu’s project received a $775,000 grant today through the Bill and Melinda Gates Foundation and Grand Challenges Canada to finance the traps and help further development.
But unclean feet and dirty socks aren’t the only items that entice a mosquito to travel in for the kill. Experts state that Limburger cheese has been specifically found being popular with certain mosquito populations. Ned Walker, a professor inside the Department of Microbiology and Molecular Genetics at Michigan State University, studies mosquitoes extensively. Walker said that anything from body build to the type of perfume you wear can be the difference between deterring and attracting the pests.
“There is a variation among attraction to different people … Men are certainly more attractive because they tend to be larger than women,” said Walker, adding that the floral scents given off by deodorants and perfumes also attract some species of mosquitoes towards the skin.
However, determining why some people leave a picnic covered in bites while others escape with out a battle wound continues to be up for debate.
“There are several [species] which can be attractive to the odors in humans. But what we want to know means that some mosquitoes are attracted to birds and never mammals, to some subsets of humans however, not all humans. It is really an active region of research,” said Walker.
Joe Conlon, technical adviser at the American Mosquito Control Association, said genetics as well as fair skin may also be a factor in attractive to mosquitoes, although scientists remain dexrpky21 whether the bites are just more noticeable on people who have fair skin.
And even though fair skin might be more alluring to the insects, lighter colors of clothing turn them off.
“It’s prudent to dress in light-colored clothing. You will discover a preference by some species to get drawn to darker colors… Wear loose fitting clothing. Mosquitoes can and will bite through tight-fitting clothing,” he was quoted saying.
Conlon claimed that the only surefire method of preventing from biting is to wear a repellant, to look at what clothes you wear and to eliminate standing water that collects in places like at the bases of flower pots and in the bottom of air conditioner drip pans.
Also, he cautioned against using any substitutes to 除臭襪 like vitamin b complex, praoclaiming that double blind tests have proven these remedies to not work effectively.
“Most of the time, everyone is not fearful enough. With West Nile Virus falling the radar, folks are less concerned. … Individuals need to [know] that they cannot just ruin your picnic, they are able to ruin your life,” said Conlon.
