From perfume, towards the shade of your shirt, right right down to the smelliness of your own feet, mosquitoes appear to find any reason to sink themselves into human skin.
Scientists say that stinky feet and socks may be included with this list of things that attract 腳臭 to feed off human blood. One African scientist is now using that bit of research to help you fight malaria in Tanzania by creating traps that offer off, trying to lure the bloodsuckers that carry the ailment to their hosts.
“Scientists have known for many years that mosquitoes smell people; which they will not see us, but rather they smell us,” wrote Dr. Fredros Okumu in a email from Tanzania where he heads the study project at the Ifakara Health Institute. “It will be the things which we produce inside our breath, sweat of skin that [mosquitoes] use like a signal to find us. So when you are wearing socks, these skin-derived chemicals remain on the sock fabric and can nevertheless be detected by mosquitoes even once you have removed your socks.”
Okumu’s project received a $775,000 grant today in the Bill and Melinda Gates Foundation and Grand Challenges Canada to fund the traps and help further development.
But unclean feet and dirty socks aren’t the only stuff that entice a mosquito to visit in for the kill. Experts say that Limburger cheese has been found to become appealing to certain mosquito populations. Ned Walker, a professor inside the Department of Microbiology and Molecular Genetics at Michigan State University, studies mosquitoes extensively. Walker mentioned that everything from body build to the kind of perfume you wear can be the distinction between deterring and attracting the pests.
“You will discover a variation among attraction to different people … Men tend to be attractive since they are usually larger than women,” said Walker, adding the floral scents given off by deodorants and perfumes also attract some species of mosquitoes to the skin.
However, determining why some people leave a picnic covered in bites while some escape with no battle wound is still up for debate.
“There are some [species] which are popular with the odors in humans. But what we wish to know is the reason some mosquitoes are drawn to birds instead of mammals, to many subsets of humans however, not all humans. It becomes an active section of research,” said Walker.
Joe Conlon, technical adviser with the American Mosquito Control Association, said genetics in addition to fair skin could also are involved in popular with mosquitoes, although scientists remain dexrpky21 if the bites are simply just more noticeable on individuals with fair skin.
Even though fair skin might be more attractive to the insects, lighter colors of clothing turn them off.
“It’s prudent to wear in light-colored clothing. You will discover a preference by some species to become attracted to darker colors… Wear loose fitting clothing. Mosquitoes will bite through tight-fitting clothing,” he explained.
Conlon stated that the sole surefire means of preventing from biting would be to wear a repellant, to watch what clothes you wear and to remove standing water that collects in places like at the bases of flower pots and towards the bottom of air-con drip pans.
He also cautioned against using any substitutes to 除臭襪 like vitamin b complex, stating that double blind tests have proven these remedies never to work effectively.
“In many cases, people are not fearful enough. With West Nile Virus falling off the radar, individuals are less concerned. … People need to [know] which they cannot just ruin your picnic, they can ruin your way of life,” said Conlon.
