害虫是如何准确找到它们想吃的植物的?美国农业研究局昆虫学家Joseph C.Dichens在一种马铃薯害虫中找到了答案。通过在害虫触角顶端放微小的电极,并监测其敏感度,他发现几种可以引诱害虫的化学香味剂。他让害虫接触几种马铃薯叶片香味,任其选择喜爱的叶片。当让害虫在一种香味剂与马铃薯叶片之间进行选择时,害虫就会发生混乱,最终胡乱 How Pests Accurately Find the Plants They Want to Eat? Joseph C. Dichens, an entomologist at the Bureau of Agricultural Research, found the answer in a potato pest. By placing tiny electrodes on top of pests and monitoring their sensitivity, he found several chemical fragrances that can attract pests. He let the pests touch several kinds of potato leaves flavor, let them choose their favorite leaves. When the pests are chosen between a fragrance and a potato leaf, pests can become confused and ultimately unorganized
