From perfume, to the colour of your shirt, right down to the smelliness of the feet, mosquitoes appear to find any reason to sink themselves into human skin.
Scientists state that stinky feet and socks might be included with the list of factors that attract 腳臭 to give off human blood. One African scientist has become using that amount of research to help fight malaria in Tanzania by creating traps that provide off, hoping to lure the bloodsuckers that carry the ailment to their hosts.
“Scientists have known for a long time that mosquitoes smell people; that they can usually do not see us, but alternatively they smell us,” wrote Dr. Fredros Okumu within an email from Tanzania where he heads the studies project on the Ifakara Health Institute. “It will be the stuff that we produce in your breath, sweat of skin that [mosquitoes] use as being a signal to find us. So if you are wearing socks, these skin-derived chemicals stay on the sock fabric and can nonetheless be detected by mosquitoes even after you have removed your socks.”
Okumu’s project received a $775,000 grant today from 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 sole things that entice a mosquito to look set for the kill. Experts state that Limburger cheese has been specifically found to become attractive to certain mosquito populations. Ned Walker, a professor in the Department of Microbiology and Molecular Genetics at Michigan State University, studies mosquitoes extensively. Walker mentioned that everything from body build to the sort of perfume you wear is most likely the difference between deterring and attracting the pests.
“There exists a variation among attraction to various people … Men tend to be more attractive mainly because they tend to be larger than women,” said Walker, adding the floral scents given off by deodorants and perfumes also attract some types of mosquitoes towards the skin.
However, determining why some people leave a picnic covered in bites although some escape with no battle wound remains to be up for debate.
“There are several [species] that happen to be attractive to the odors in humans. But what we want to know is the reason some mosquitoes are attracted to birds and not mammals, for some subsets of humans although not all humans. It is an active region of research,” said Walker.
Joe Conlon, technical adviser with the American Mosquito Control Association, said genetics and also fair skin might also play a role in attractive to mosquitoes, although scientists remain dexrpky21 if the bites are merely more noticeable on those with fair skin.
And although fair skin is much more alluring to the insects, lighter colors of clothing turn them off.
“It’s prudent to dress in light-colored clothing. There is a preference by some species to be interested in darker colors… Wear loose fitting clothing. Mosquitoes can bite through tight-fitting clothing,” he said.
Conlon stated that the only surefire way of preventing from biting is always to wear a repellant, to watch what clothes you wear and to get rid of standing water that collects in places like with the bases of flower pots and towards the bottom of air conditioning drip pans.
Also, he cautioned against using any substitutes to 除臭襪 like vitamin B, praoclaiming that double blind tests have proven these remedies never to work effectively.
“In many cases, folks are not fearful enough. With West Nile Virus falling the radar, folks are less concerned. … Individuals need to [know] that they can cannot just ruin your picnic, they can ruin your life,” said Conlon.
