British scientists reveal why mosquitoes are more "favored" by certain people
Are you more vulnerable to mosquitoes on summer nights than others? Perhaps you still do not understand why you are "favored" by mosquitoes, and now scientists will reveal this mystery to you. Scientists at the British Biotechnology and Biological Sciences Research Council (bbsrc) said recently that they may have discovered why some people are more likely to be bitten by mosquitoes. In addition, their research may also lead to the emergence of a safer, more natural new type of pesticide. Discovering a special “masking†smell According to the “Daily Science†website of the United States on January 27th, James Logan was a graduate student at the British Lausanne Institute sponsored by bbsrc. He found that some people could emit a kind of "Masked" odor, which effectively prevents mosquito bites. James Logan’s study was based on an earlier study by the Lausanne Institute. This early study was led by Prof. John Pictet. Their results showed that the number of mosquitoes and flies in the herd depends on whether certain cattle are present, and these cattle can release a difference. The chemical signals to repel mosquitoes. When these cattle that release different chemical signals are moved to other places, the number of mosquitoes and flies in the entire herd will increase again. Logan and Professor Jenny Merdu of the University of Aberdeen, UK, worked together to study the odors emitted by volunteers and the response of mosquitoes to odors. During the study, the mosquitoes were placed in a y-tube that could be moved against the wind down to any branch of the y-tube. The air in one of the branches was mixed with the odor emitted by the volunteer's arm. The results of the study showed that the difference in the degree of attracting the mosquitoes to the volunteers depends on some mixture of components emitted by unattractive individuals. This particular mixture can “cut†the odor of the body and attract mosquitoes by playing the role of an insect repellent or “masking†the components of the human body that attract mosquitoes. At present, scientists are studying this conclusion in more depth. They used a sleeping bag made of thin metal foil to collect the odor emitted by volunteers and then used it to test it. Professor Julia Goodfootfeller, chief executive of the UK's Biotechnology and Biological Sciences Research Council, is expected to develop a new type of insecticide. "People can get the visible benefits from this research. Discover why some people are more attracted to mosquitoes. After the reason, scientists can use this research to develop a safer, more natural pesticide, and this kind of pesticide should be better than traditional products.†Logan also said that After identifying the main components of this mixture and knowing how they work, people can find more effective ways to avoid mosquito bites, and at the same time reduce the unnecessary trouble caused by mosquitoes and effectively prevent related diseases. spread.
