Second,we set the database of morphological characteristics of intercepted and captured bark beetle during quarantine,and the last,we studied the molecular identification of 15 species.The results were showed as below.1.Application of bark beetle semiochemicals in timber quarantine1.1 EAG and walking responses of bark beetle to different semiochemicalsSemiochemicals which can induce the olfactory response and aggregation behavior of bark beetle include host volatile components,pheromones secreted by bark beetles itself or synthesized with host compounds by bark beetles,and the compounds released by tissue of decaying wood under the pressure of microorganism after bark beetle colonization.
信息化合物在小蠹虫检疫中的应用1.1小蠹虫对各种信息化合物的触角电位及嗅觉反应能诱发小蠹虫产生嗅觉反应，进而使之产生聚集行为的信息化合物有很多种，主要包括：树木的挥发性组分；小蠹虫自身产生的信息素和寄生后转化寄主化学物质合成的信息素统称虫体信息素以及树木被小蠹虫寄生后，其组织在微生物作用下释放的物质。
