Mosquitoes use smell, sight and heat in that order when looking for food. Scientists in American have established that mosquitoes first hum in on targets when they smell the carbon dioxide or CO2 that living creatures breathe out. The tiny insects can sniff out CO2 from up to 50 meters and use this sense of smell to locate the source visually. Then, once they’re a few centimeters away from a target, they’re attracted to its warmth. The research was published in the journal Current Biology.
蚊子会依此使用嗅、视、热来觅食，美国科学家发现蚊子是通过闻到二氧化碳或生物呼吸出的二氧化碳来寻找目标的。这种小昆虫能闻出50米远的二氧化碳，并使用其嗅觉来寻找其来源。一旦距离目标只有几厘米远，它们就被其温暖所吸引。这份研究发表在期刊《当代生物学》上。
