Scientists think the most important variable mosquitoes rely on when choosing one person over another are the chemical compounds produced by the colonies of microbes that live on our skin.
科学家们认为,蚊子选择某个特定的人作为叮咬目标依据的一个最重要因素是,皮肤上微生物菌落产生的化学成分。
"Bacteria convert the secretions of our sweat glands into volatile compounds that are taken through the air to the olfactory system on the head of the mosquitoes," Van Loon told Live Science.
范隆告诉美国趣味科学网站说:“细菌把人类汗腺的分泌物变成挥发性混合物,通过空气进入位于蚊子头部的嗅觉系统。”
secretion [sɪ'kriːʃ(ə)n]:n.分泌;分泌物
volatile ['vɒlətaɪl]:adj. [化学]挥发性的;不稳定的
olfactory [ɒl'fækt(ə)rɪ]:adj.嗅觉的;味道的
These chemical bouquets are complex, including upward of 300 different compounds, and they vary from person to person based on genetic variation and environment.
这些混合物的化学气味很复杂,含有300多种成分,而且因为基因差异和环境不同,因人而异。
