Anopiophora glabripennis (Motsch.) (Coleoptera: Cerambycidae) is a destructive woodborer, attacking many species of deciduous hardwood trees. Apriona swainsoni (Hope) (Coleoptera: Cerambycidae) is a woodborer of Sophora japonica L. (Angiospermae: Fabaceae). Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae) is an important natural enemy of both Cerambycid species in China. Kairomones for two populations of D. helophoroides that parasitize A. glabripennis and A. swainsoni respectively were studied. Based on identification and quantification of volatiles from larval frass produced by A. glabripennis and A. swainsoni, monoterpenes were selected to test their kairomonal activity to both populations of D. helophoroides adults using a Y-tube olfactometer. The results indicated that (S)-(-)-limonene served as a kairomone for the population of D. helophoroides parasitized A. glabripennis. α-pinene, (IR)-(+)-αpinene and (+)-β-pinene were attractive to the population of D. helophoroides parasitized A. swainsoni. The results provide information about the co-evolution of D. helophoroides, its host, and host-food trees.
白杨透翅蛾（Motsch.）（鞘翅目：天牛科）是一种破坏性的蛀木昆虫，攻击许多落叶硬木树种。桑天牛（Hope）（鞘翅目：天牛科）是槐树（被子植物门：豆科）的蛀木昆虫。宽背长足虻（Fairmaire）（鞘翅目：长足虻科）是中国两种天牛的重要天敌。对分别寄生在白杨透翅蛾和桑天牛幼虫粪便中的两种宽背长足虻种群的信息素进行了研究。基于对白杨透翅蛾和桑天牛幼虫粪便中挥发物的鉴定和定量，选择单萜类化合物，使用 Y 型嗅觉仪测试它们对两种宽背长足虻种群成虫的信息素活性。结果表明，（S）-（-）-柠檬烯是寄生在白杨透翅蛾上的宽背长足虻种群的信息素。α-蒎烯、（IR）-（+）-α-蒎烯和（+）-β-蒎烯对寄生在桑天牛上的宽背长足虻种群具有吸引力。研究结果提供了有关宽背长足虻与其宿主和宿主食物树共同进化的信息。
