Bed bugs have become a global epidemic and current detection tools are poorly suited for routine surveillance. Despite intense research on bed bug aggregation behavior and the aggregation pheromone, which could be used as a chemical lure, the complete composition of this pheromone has thus far proven elusive. Here, we report that the bed bug aggregation pheromone comprises five volatile components (dimethyl disulfide, dimethyl trisulfide, (E)-2-hexenal, (E)-2-octenal, 2-hexanone), which attract bed bugs to safe shelters, and one less-volatile component (histamine), which causes their arrestment upon contact. In infested premises, a blend of all six components is highly effective at luring bed bugs into traps. The trapping of juvenile and adult bed bugs, with or without recent blood meals, provides strong evidence that this unique pheromone bait could become an effective and inexpensive tool for bed bug detection and potentially their control.
臭虫已成为全球性的流行病，而当前的检测工具并不适合常规监测。尽管人们对臭虫的聚集行为和聚集信息素进行了深入研究，这些信息素可以作为化学诱饵，但到目前为止，这种信息素的完整成分仍然难以捉摸。在这里，我们报告说，臭虫聚集信息素由五种挥发性成分（二甲基二硫、二甲基三硫、(E)-2-己烯醛、(E)-2-辛烯醛、2-己酮）组成，这些成分吸引臭虫到安全的避难所，还有一种挥发性较小的成分（组氨酸），当臭虫接触到它时会导致其被捕。在受感染的场所，六种成分的混合物非常有效地引诱臭虫进入陷阱。诱捕有或没有近期血餐的幼年和成年臭虫，有力地证明了这种独特的信息素诱饵可以成为一种有效且廉价的臭虫检测工具，并可能有助于控制臭虫。
