摘要：松褐天牛 Monochamus galloprovincialis 是最近引入的松材线虫的欧洲媒介。这种线虫是松材线虫病的致病生物，松材线虫病是东亚严重的树木杀手。现在需要有效的诱饵和陷阱来监测和控制这种甲虫。西班牙研究了单独释放的树皮甲虫 (Ips spp.) 信息素成分（ipsenol）或混合物（ipsenol、ipsdienol、顺式马鞭草醇和甲基丁烯醇）以及宿主挥发物（松节油或 α-蒎烯和乙醇）对 M. galloprovincialis 陷阱捕获量的影响。发现了雄性和雌性 M. galloprovincialis 对 Ips 化学信息素的利特蒙反应。与单独的宿主挥发物相比，甲虫更容易被补充有树皮甲虫信息素的宿主混合物所吸引。单独的异丙醇对松木锯木工很有吸引力，并且与 α-蒎烯和乙醇具有协同作用。四种 Ips 化学信息素和主体化合物的完全混合非常有吸引力。当被捕获的甲虫逃逸被阻止时，多重漏斗陷阱与黑色十字叶片陷阱一样有效地捕捉这种昆虫。还评估了非目标树皮甲虫捕食者的诱捕。蓝纹蜥蜴（Temnochila coerulea）和蚁蜥蜥蜴（Thanasimus formicarius）被用树皮甲虫信息素作为诱饵的陷阱所吸引并被杀死。这些结果表明，通过用寄主挥发物和 Ips 化学信息素作为诱饵，可以有效监测 M. galloprovincialis，但应考虑减少诱饵成分和改造陷阱，以尽量减少对捕食者的影响。
Abstract: The pine sawyer Monochamus galloprovincialis is the European vector of the recently introduced pine wood nematode. This nematode is the causal organism of pine wilt disease, a serious tree killer in East Asia. Efficacious baits and traps to monitor and control this beetle are now required. The effect of bark beetle (Ips spp.) pheromone components, released individually (ipsenol) or in blends (ipsenol, ipsdienol, cis‐verbenol and methyl‐butenol), together with host volatiles (turpentine or α‐pinene and ethanol) on M. galloprovincialis trap catches has been studied in Spain. A kairomonal response by male and female of M. galloprovincialis to Ips semiochemicals was found. Beetles were more attracted to host blends supplemented with bark beetle pheromones than to host volatiles alone. Ipsenol alone was attractive to pine sawyers, and was synergistic with α‐pinene and ethanol. The full blend of the four Ips semiochemicals and the host compounds was highly attractive. Multiple‐funnel traps were as effective as black cross‐vane traps in capturing this insect when the escape of trapped beetles was prevented. Trapping of non‐target bark beetle predators was also evaluated. The trogossitid Temnochila coerulea and clerid Thanasimus formicarius were kairomonally attracted to and killed in traps baited with bark beetle pheromones. These results suggest that effective monitoring of M. galloprovincialis would be possible by baiting any of these traps with host volatiles and Ips semiochemicals, but reduction of the lure components and trap modification to minimize impact on predators should be considered.
