Geranyl butyrate (GB) and (E, E)-farnesyl butyrate (FB) were identified in the pheromone gland extract of females of the click beetle, Agriotes brevis (Candeze) (Coleoptera: Elateridae) as the major sex pheromone components. Polyethylene vial dispensers containing 20-200 mg of a 1:1 mixture caught high numbers of beetles. Captures did not decrease even after 73 days of field exposure of dispensers. At sites where both Agriotes sputator L. and A. brevis were present, the above baits were selectively catching only A. brevis, despite the fact that GB is also the main pheromone component of A. sputator, suggesting that FB has a role in reproductive isolation. In the early part of the season, traps into which the insects could both crawl and fly captured more A. brevis than designs where the insects could only fly in. Trap design was not important later in the season. This indicates the need for future development of a trap suitable for use throughout the whole season.
在短角叩甲（Agriotes brevis (Candeze)，鞘翅目：叩甲科）雌虫的性信息素腺体提取物中，鉴定出丁酸香叶酯（GB）和（E, E）-法尼醇丁酸酯（FB）为主要的性信息素成分。装有20 - 200毫克1:1混合物的聚乙烯小瓶诱捕器捕获了大量甲虫。即使诱捕器在田间暴露73天后，捕获量也没有减少。在同时存在普通叩甲（Agriotes sputator L.）和短角叩甲的地点，上述诱饵仅能选择性地捕获短角叩甲，尽管GB也是普通叩甲的主要性信息素成分，这表明FB在生殖隔离中发挥作用。在季节早期，昆虫既能爬行又能飞进的诱捕器捕获的短角叩甲比昆虫只能飞进的设计诱捕器更多。在季节后期，诱捕器设计并不重要。这表明未来需要开发一种适合在整个季节使用的诱捕器。
