From perfume, on the colour of your shirt, right down to the smelliness of your respective feet, mosquitoes seem to find any reason to sink themselves into human skin.
Scientists say that stinky feet and socks can be added to this list of things that attract 腳臭 to feed off human blood. One African scientist has become using that little bit of research to aid fight malaria in Tanzania by creating traps which provide off, looking to lure the bloodsuckers that carry the condition for their hosts.
“Scientists have known for some time that mosquitoes smell people; they do not see us, but rather they smell us,” wrote Dr. Fredros Okumu in an email from Tanzania where he heads the research project on the Ifakara Health Institute. “This is the items that we produce within our breath, sweat of skin that [mosquitoes] use as a signal to locate us. When you are wearing socks, these skin-derived chemicals stay on the sock fabric and can still be detected by mosquitoes even after 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 only items that entice a mosquito to visit in for the kill. Experts claim that Limburger cheese has additionally been found being popular with 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 kind of perfume you wear can be the difference between deterring and attracting the pests.
“You will discover a variation among attraction to different people … Men tend to be attractive mainly because they tend to be bigger than women,” said Walker, adding the floral scents given off by deodorants and perfumes also attract some type of mosquitoes towards the skin.
However, determining why some individuals leave a picnic covered in bites and some escape without having a battle wound continues to be up for debate.
“There are many [species] which are popular with the odors in humans. But what we should know is the reason why some mosquitoes are fascinated by birds and not mammals, to many subsets of humans however, not all humans. It becomes an active region of research,” said Walker.
Joe Conlon, technical adviser in the American Mosquito Control Association, said genetics along with fair skin might also be a factor in appealing to mosquitoes, although scientists remain dexrpky21 if the bites are just more noticeable on people with fair skin.
Even though fair skin might be more popular with 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 to be fascinated by darker colors… Wear loose fitting clothing. Mosquitoes will bite through tight-fitting clothing,” he stated.
Conlon stated that the only surefire strategy for preventing from biting would be to wear a repellant, to look at what clothes you wear and to eradicate standing water that collects in places like at the bases of flower pots and towards the bottom of air conditioner drip pans.
He also cautioned against using any substitutes to 除臭襪 like b vitamin, praoclaiming that double blind tests have proven these remedies not to work effectively.
“Most of the time, people are not fearful enough. With West Nile Virus falling the radar, people are less concerned. … Young people need to [know] that they can cannot just ruin your picnic, they are able to ruin your lifestyle,” said Conlon.
