摘　　要：选用2-(十一烷氧基)-乙醇(Monochamol)、6,10-二甲基十一烷-5,9-二烯醇(E/Z-fuscumol)、6,10-二甲基-5,9-十一二烯-2-乙酸乙酯(E/Z-fuscumol acetate)3种天牛信息素和荜澄茄油(cubeb oil)诱芯,辅以黑色飞翔拦截诱捕器进行林内诱集,筛选不同天牛种类高效信息化合物诱芯,监测阔叶红松林内天牛种类和数量,以及松材线虫病潜在媒介天牛的种群动态。结果表明:cubeb oil增加E/Z-fuscumol+E/Z-fuscumol acetate对花天牛亚科的诱集作用,降低Monochamol对云杉花墨天牛的诱集数量;E/Z-fuscumol+E/Z-fuscumol acetate与Monochamol和/或cubeb oil组合可增加诱集的天牛种类。在实际应用中应根据特定天牛种类选择植物挥发物作为信息素诱芯的增效剂;在云杉花墨天牛、云杉大墨天牛的监测和大量诱捕时可选用Monochamol+E/Z fuscumol acetate+E/Z fuscumol组合,提高诱捕效率;在一般性天牛种群监测调查中为降低成本可使用单一Monochamol诱芯。To screen the efficient attractants of different Cerambycidae species,and monitoring species and individuals of cerambycid beetles in pine forests,especially the population dynamics of potential vector longhorn beetles of pine wilt disease.Three cerambycid pheromones of 2-(undecyloxy)ethanol(Monochamol),(E)-6,10-dimethyl-5,9-undecadien-2-ol(E/Z-fuscumol),(E)-6,10-dimethyl-5,9-undecadien-2-yl acetate(E/Z-fuscumol acetate)and cubeb oil were used as attractants,supplemented by black intercept panel traps for field trapping experiments.The findings revealed that cubeb oil increased attractive effect of(E)-6,10-dimethyl-5,9-undecadien-2-ol(E/Z-fuscumol)+(E)-6,10-dimethyl-5,9-undecadien-2-yl acetate(E/Z-fuscumol acetate)on Lepturinae,reduced individual number of 2-(undecyloxy)ethanol(Monochamol)on Monochamus saltuarius.The combina-tion of E/Z-fuscumol+E/Z-fuscumol acetate with Monochamol and/or cubeb oil increased the number of captured cerambycid species.In practical application,plant volatiles should also be selected as pheromone synergists according to specific cerambycid species.The combination of Monochamol+E/Z fuscumol acetate+E/Z fuscumol can be used to improve the trapping efficiency in monitoring and control of M.saltuarius and M.urussovi.To reduce the cost,a single Monochamol lure can be used in general cerambycid population monitoring survey.
