From perfume, for the colour 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 could be included in the list of things that attract 腳臭 to feed off human blood. One African scientist is now using that little bit of research to aid fight malaria in Tanzania by creating traps that provide off, looking to lure the bloodsuckers that carry the disease to their hosts.
“Scientists have known for some time that mosquitoes smell people; that they tend not to see us, but instead they smell us,” wrote Dr. Fredros Okumu in a email from Tanzania where he heads the study project at the Ifakara Health Institute. “This is basically the items that we produce in your breath, sweat of skin that [mosquitoes] use being a signal to find 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 through 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 sole items that entice a mosquito to travel set 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 everything from body build to the sort of perfume you wear could be the distinction between deterring and attracting the pests.
“You will discover a variation among attraction to several people … Men tend to be more attractive since they are usually larger than women,” said Walker, adding that this floral scents given off by deodorants and perfumes also attract some species of mosquitoes towards the skin.
However, determining why a lot of people leave a picnic covered in bites while some escape with no battle wound remains to be up for debate.
“There are some [species] that are appealing to the odors in humans. But what we want to know means that some mosquitoes are attracted to birds instead of mammals, to a few subsets of humans although not all humans. It is an active section of research,” said Walker.
Joe Conlon, technical adviser in the American Mosquito Control Association, said genetics in addition to fair skin might also be a factor in fascinating to mosquitoes, although scientists remain dexrpky21 regardless of if the bites are just more noticeable on those with fair skin.
And although fair skin is much more appealing 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 drawn to darker colors… Wear loose fitting clothing. Mosquitoes can bite through tight-fitting clothing,” he said.
Conlon mentioned that really the only surefire strategy for preventing from biting is usually to wear a repellant, to watch what clothes you wear and to get rid of standing water that collects in places like at the bases of flower pots and towards the bottom of air cooling 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 never work effectively.
“On many occasions, people are not fearful enough. With West Nile Virus falling off the radar, folks are less concerned. … Young people need to [know] that they cannot just ruin your picnic, they are able to ruin your daily life,” said Conlon.
