CNN News:新研究表明蚊子喜欢叮咬体味重的人

Source: 恒星英语学习网    2019-11-25   English BBS   Favorite  

Which of these animals hibernates in winter? Tree squirrel, mosquito, monarch butterfly or silverfish. Mosquitoes are the only animals on this list that enter diapause, a hibernation-like period of shutting down for the cold winter months.
So that explains why the pesky pests always come back in the summer, and when they do, why do they always seem to bite some people more often than others? Scientists say there are a number of things mosquitoes are attracted to. Strongly scented soaps are believed to get their attention along with certain deodorants and perfume. The increased carbon dioxide we give off when we're exercising can create a buzz among the insects, as well as our sweat. As far as clothing goes, researchers are divided over whether it's bright or dark clothes that make us easier for mosquitoes to spot but a recent study has found that different types of body odor could make some people more prone to mosquito bites than others.

Is there anything that could be done about that? Maybe one day if a drug is designed that can change those odors. Could that have side effects of its own? Yes, but because of the diseases they carry mosquitoes are responsible for more human deaths than any other animal. There's a lot of international interest in keeping them away.
