From perfume, to the color of your shirt, right to the smelliness of your feet, mosquitoes manage to find any reason to sink themselves into human skin.
Scientists say that stinky feet and socks may be added to their list of factors that attract 腳臭 to feed off human blood. One African scientist has become using that little research to aid fight malaria in Tanzania by creating traps that provide off, trying to lure the bloodsuckers that carry the ailment with their hosts.
“Scientists have known for a long period that mosquitoes smell people; that they usually do not see us, instead they smell us,” wrote Dr. Fredros Okumu inside an email from Tanzania where he heads the research project with the Ifakara Health Institute. “It will be the stuff that we produce in our breath, sweat of skin that [mosquitoes] use like a signal to locate us. So if you are wearing socks, these skin-derived chemicals stay on the sock fabric and may still be detected by mosquitoes even once 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 fund the traps and help further development.
But unclean feet and dirty socks aren’t the only items that entice a mosquito to visit set for the kill. Experts state that Limburger cheese has been specifically found to get 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 could possibly be the distinction between deterring and attracting the pests.
“There is a variation among attraction to different people … Men are usually attractive mainly because they are usually larger than women,” said Walker, adding the floral scents given off by deodorants and perfumes also attract some types of mosquitoes on the skin.
However, determining why some people leave a picnic covered in bites while some escape with out a battle wound is still up for debate.
“There are many [species] that happen to be appealing to the odors in humans. But what we want to know means that some mosquitoes are attracted to birds and never mammals, to many subsets of humans however, not all humans. It becomes an active part of research,” said Walker.
Joe Conlon, technical adviser at the American Mosquito Control Association, said genetics as well as fair skin might also are involved in appealing to mosquitoes, although scientists remain dexrpky21 whether or not the bites are just more noticeable on individuals with fair skin.
And even though fair skin is much more appealing to the insects, lighter colors of clothing turn them off.
“It’s prudent to wear in light-colored clothing. There is a preference by some species being drawn to darker colors… Wear loose fitting clothing. Mosquitoes will bite through tight-fitting clothing,” he said.
Conlon claimed that really the only surefire way of preventing from biting is always to wear a repellant, to look at what clothes you wear and to remove standing water that collects in places like with the bases of flower pots and in the bottom of air conditioner drip pans.
He also cautioned against using any substitutes to 除臭襪 like vitamin B, praoclaiming that double blind tests have proven these remedies not to work effectively.
“On many occasions, people are not fearful enough. With West Nile Virus falling off the radar, individuals are less concerned. … Young people need to [know] they cannot just ruin your picnic, they are able to ruin your lifestyle,” said Conlon.
