Why do mosquitoes bite some people and not others?
That is quite an interesting question. There is some evidence that they tend to bite women rather than men. This is thought to be because they are attracted to female pheromones. There may be other chemical differences in sweat that cause preferential biting as well. Another element that confuses the issue is that people vary a great deal as to how strongly they react to the bite. This depends on how allergic you are to the mosquito saliva. The more sensitive you are the worse the swelling, redness and itch. This means that some people who are bitten are hardly aware of the bite, as they do not respond to it. This may give the mistaken impression that they are not being bitten.
