1. Tetropium gabrieli is native to the European Alps where it breeds in European larch and may be an important pest during drought periods by killing trees. It has spread to larch plantations in several European countries including Sweden.
2. In trapping studies conducted in Sweden, we tested whether T. gabrieli was attracted to E‐fuscumol, E,Z‐fuscumol, E,Z‐fuscumol acetate and the host volatile combination of α‐pinene plus ethanol. We also compared its response with those of the native congeners, T. fuscum and T. castaneum.
3. All three Tetropium species were caught in significantly higher numbers in traps baited with E‐fuscumol plus host volatiles than in traps baited with host volatiles alone or in unbaited traps.
4. There was no difference in catch of any Tetropium species between traps baited with E‐fuscumol plus host volatiles versus traps baited with E,Z‐fuscumol plus host volatiles, but the latter treatment caught more T. fuscum and T. castaneum than did E,Z‐fuscumol acetate plus host volatiles.
5. The addition of E‐fuscumol to host volatile‐baited traps significantly reduced mean catch of T. gabrieli, significantly increased mean catch of T. castaneum, and had no significant effect on catch of T. fuscum. Mean catch of all three species was significantly greater in traps baited with E‐fuscumol alone than in traps baited with host volatiles alone.
6. All three species were caught from May to August. The median date of captures was about 2 weeks earlier for T. fuscum compared with the other two species.

陶醉的甲虫Tetropium gabrieli，T.castaneum和T.fuscum对信息素和寄主树挥发物的吸引力

1. Tetropium gabrieli原产于欧洲阿尔卑斯山，在欧洲落叶松中繁殖，在干旱时期通过杀死树木可能是重要的害虫。它已经蔓延到包括瑞典在内的多个欧洲国家的落叶松人工林。
2. 在瑞典进行的诱捕研究中，我们测试了T. gabrieli是否被E-富马酚，E，Z-富马酚，E，Z-富马酚乙酸酯和α-pine烯加乙醇的挥发性混合物吸引。我们还比较了其与本地同类动物T. fuscum和T. castaneum的反应。
3. 与单独用宿主挥发物诱饵或未诱饵诱捕器诱捕的E- fuscumol加上宿主挥发物诱捕器相比，所有三种Tetropium种类的捕获率都高得多。
4. 用E-富仲醇加宿主挥发物诱捕的诱集物与用E，Z-富仲醇加宿主挥发物诱捕的诱集物的捕获物中没有任何特罗伯铵物种的差异，但是后一种处理比E，捕获了更多的T. Fuscum和T. castaneum 。醋酸Z-枯草醇加主体挥发物。
5. 添加的E- fuscumol到主机挥发诱饵显著减少的平均渔获T.加布里埃利，显著上升的平均捕捞赤拟谷盗，且对捕捞没有显著影响T. fuscum。所有三个品种的平均产量为显著更大的陷阱与诱饵E-单独fuscumol比陷阱诱饵与主机单独挥发物。
6. 从五月到八月都捕获了这三个物种。与其他两个物种相比，T.fuscum的捕获中位日期大约早了2周。
