Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), commonly known as the Asian longhorned beetle, is a wood-boring invasive species introduced from Asia to North America and Europe in solid wood packing material. Efficient monitoring traps are needed to assess population density and dispersal in the field and to detect new introductions at ports of entry. For this purpose, we conducted field trapping experiments in China in the summers of 2007 and 2008. In 2007, we tested Intercept panel traps hung on poplar trees. In 2008, we used Intercept panel traps hung on poplar trees, screen sleeve traps wrapped around poplar trunks, and Intercept panel traps hung on bamboo poles 20 m away from host trees. Traps were baited with A. glabripennis male-produced pheromone alone or in different combinations with plant volatiles. Traps baited with the male-produced pheromone alone caught significantly more females than control traps in both years. The addition of a mixture of (-)-linalool, (Z)-3-hexen-1-ol, linalool oxide, trans-caryophyllene, and trans-pinocarveol to the pheromone significantly increased trap catches of females, 85% of which were virgin. Screen sleeve traps baited with a combination of (-)-linalool and the pheromone caught the highest number of beetles overall in 2008, whereas traps placed on bamboo polls caught the lowest number. Although the logistics for the most effective implementation of a trapping program using a mixture of the pheromone and plant volatiles require additional studies, these results indicate that this pheromone has considerable promise as a monitoring tool for A. glabripennis in the field.
光肩星天牛（Anoplophora glabripennis (Motschulsky)，鞘翅目：天牛科），通常被称为亚洲长角天牛，是一种通过实木包装材料从亚洲引入北美和欧洲的蛀木入侵物种。需要高效的监测诱捕器来评估田间种群密度和扩散情况，并在入境口岸检测新传入的个体。为此，我们于2007年和2008年夏季在中国进行了田间诱捕实验。2007年，我们测试了悬挂在杨树上的Intercept面板诱捕器。2008年，我们使用了悬挂在杨树上的Intercept面板诱捕器、包裹在杨树树干上的筛网套筒诱捕器，以及悬挂在距离寄主树20米远的竹竿上的Intercept面板诱捕器。诱捕器单独用光肩星天牛雄虫产生的性信息素诱饵，或与植物挥发物以不同组合进行诱饵。在这两年中，仅用雄虫产生的性信息素诱饵的诱捕器捕获的雌虫数量显著多于对照诱捕器。在性信息素中添加（-）-芳樟醇、（Z）-3-己烯-1-醇、氧化芳樟醇、反式石竹烯和顺式松油二环烯的混合物，显著增加了诱捕器捕获的雌虫数量，其中85%为处女雌虫。2008年，用（-）-芳樟醇和性信息素组合诱饵的筛网套筒诱捕器捕获的甲虫总数最高，而放置在竹竿上的诱捕器捕获的数量最低。尽管使用性信息素和植物挥发物混合物最有效地实施诱捕计划的后勤工作需要进一步研究，但这些结果表明，这种性信息素作为田间光肩星天牛的监测工具具有很大的前景。
