摘　　要：【目的】筛胸梳爪叩甲(Melanotus cribricollis)是我国竹区最为重要的笋期地下害虫,是竹林金针虫的优势种,分离鉴定其性信息素对于该虫的高效监测和绿色防控有着重要价值。【方法】利用气质联用仪结合林间诱捕生测试验首次对筛胸梳爪叩甲雌虫的性信息素组分进行了分离鉴定。【结果】E-11,13-Tetradecadien-1-ol和n-Dodecyl acetate是筛胸梳爪叩甲雌虫性信息素的关键组分,二者按25∶75比例混合配制成性信息素诱芯对筛胸梳爪叩甲雄虫具明显的引诱作用,每个诱捕器的诱捕量可达(60.30±3.05)头。在所比较的3种诱捕器中,撞板式诱捕器引诱效果最好。【结论】所分离鉴定的性信息素化合物对筛胸梳爪叩甲成虫有强烈的引诱作用,可用于竹林金针虫的种群监测和防治。【Objective】Melanotus cribricollis is the most important subterranean pest during the shooting period in bamboo growing area in China,which is the donminant species of bamboo forest wireworms.It is highly valuable to separate and identify the sex pheromones for efficient monitoring and green prevention and control of this pest.【Method】For the first time,the sex pheromone components of the female M.cribricollis adults were separated and identified by using a gas chromatographymass spectrometry combined with forest trapping and bioassay experiments.【Result】E11,13Tetradecadien1ol and nDodecyl acetate were the key components of sex pheromones of the female M.cribricollis adults.The sex pheromone lure mixed with the two chemicals at a ratio of 25∶75 showed a significant attraction towards the male beetles,and the number of adults captured was(60.30±3.05)beetles per trap.Among the 3 compared traps,the collision plate trap had the best attraction effect.【Conclusion】The sex pheromone compounds separated and identified have a strong attraction effect on the beetles,and can be used for population monitoring and prevention and control of the bamboo forest wireworms.
