双语阅读:为什么有些人那么招蚊子?

Some people can sit outside all summer long and not suffer from mosquito bites. Others turn into an itchy mess despite bathing in DEET and never leaving the purple glow of the bug zapper.

有些人可以整个夏天坐在户外乘凉却不被蚊子叮咬,而另有一些人即便用含驱蚊胺的沐浴露洗浴、随身带着灭蚊灯,却仍遭蚊子叮咬而奇痒难耐。

It's mostly about the invisible chemical landscape of the air around us. Mosquitoes take advantage of this landscape by using specialized behaviors and sensory organs to find victims by following the subtle chemical traces their bodies leave behind.

这主要是因为我们身体周围空气中肉眼看不见的化学成分。通过特殊习性和感觉器官,蚊子利用这种化学环境,跟踪人体留下的细微化学痕迹找到叮咬对象。

In particular, mosquitoes rely on carbon dioxide to find their hosts. When we exhale, the carbon dioxide from our lungs doesn't immediately blend with the air. It temporarily stays in plumes that mosquitoes follow like breadcrumbs.
