The defensive froth emitted by the grasshopper Romalea microptera contains several odorous compounds (phenols, terpenes, benzoquinone), including a chlorinated aromatic compound, 2,5-dichlorophenol. This compound, which is repellent to ants and therefore defensively useful to the grasshopper, probably stems from herbicide or herbicide derivative ingested by the insect with its diet. Although there is precedent for the defensive employ by one species of chemical agents produced by another, no instance was known involving secondary utilization of a pesticide dispensed by man.
美洲沙漠蝗（Romalea microptera）分泌的防御性泡沫含有几种有气味的化合物（酚类、萜类、苯醌），包括一种氯化芳香化合物2,5-二氯苯酚。这种化合物对蚂蚁具有驱避作用，因此对蝗虫具有防御作用，它可能源于蝗虫在饮食中摄入的除草剂或除草剂衍生物。虽然存在一种生物利用另一种生物产生的化学物质进行防御的先例，但此前尚无涉及人类施用的杀虫剂被二次利用的情况。
