In their experiments, the mosquitoes overwhelmingly navigated toward the source with body heat, as opposed to the one that just had body odor and carbon dioxide (CO2). We already knew that they can sniff out the carbon dioxide that we exhale, but this may be yet another tool that helps ...
Science reveals that a variety of factors might make you more palatable to mosquitoes, from your skin microbiota (微生物群) and carbon dioxide emitted in your breath to the color of clothing you’re wearing (with colors like red, orange, and black being the most attractive to mosquitoes) ....
Vosshall and her team have also begun to study how genetics contribute to mosquitoes’ choice of a host. She’s even created a breed that is unable to sense carbon dioxide, an important trigger for the insects. “By using genetics to make mutant(变异的) mosquitoes, we can document exactly...
(流汗). So, when you exercise, mosquitoes may catch your smells and fly after you. That's because exercising causes your muscles to build up lactic acid. Also, your sweat sends out carbon dioxide and your body temperature increases. But not everyone produces carbon dioxide and lactic acid ...
The more we breathe, the more carbon dioxide we send into the air, inviting bugs our way. Then there are the factors that are more dependent on how you act throughout the day. If you are to do a hard workout outside, you might breathe more heavily and produce more carbon dioxide, ...
Contrary to popular belief, blood type has no proven impact on mosquito bite preference. Mosquitoes are lured by body heat, respiration and sweat levels. Certain individuals, such as those with fast respiration and a higher rate of carbon dioxide exhalation, are more appealing. Sweatier people als...
Carbon dioxide effected full spiracular opening in proportion to the O2 concentration. The duration of spiracular opening, regardless of amplitude, was also proportional to the ratio of CO2 to O2. Responses of Aedes spiracles to hypoxia and CO2 decreased with increasing duration of exposure.KRAF...
由第二段第一句I can smell the carbon dioxide on people's' breath.译为“我能闻到人们呼吸中的二氧化碳。”可知,蚊子能够闻到二氧化碳,但并没有说二氧化碳是浓烈的气味。且没有说蚊子喜欢二氧化碳。再结合第三段第二、三句的 You play outside and start sweating all over. I can smell the lactic acid ...
I can smell the carbon dioxide (二氧化碳) on people's breath. The more you breathe out, the more easily I can find you. This means larger and fatter people are more likely to get my "kiss". I can also find food by smelling. You play outside and start sweating (出汗) all over. ...
