The Asian longhorned beetle (Anoplophora glabripennis) attacks apparently healthy trees, and more effective tools for surveying and monitoring them are needed. To better understand how the beetle recognizes and locates its hosts, we compared adult feeding on and orientation to cut branches of Acer negundo (a preferred host), Salix matsudana, Ailanthus altissima and Pinus bungeana, and found that adults preferred Acer negundo to others. We then evaluated whether color cues enhanced host (A. negundo) odor attractiveness for A. glabripennis. We assessed preference of adult A. glabripennis for colors that mimicked the bark of cut branches and found that adults were significantly attracted by forest green. We examined the effect of plant odors alone and found no significant difference among tested plants; however, the combination of forest green and A. negundo odors was more attractive to adults than combinations of other colors with A. altissima and P. bungeana odors. Finally, we studied the interaction between color and odor to determine their potential influence on A. glabripennis behavior. We found that combinations of cues that included forest green and host odor were more attractive to adults than others, but these preference of adults for forest green was disrupted by A. altissima odors.

亚洲长角甲虫（Anoplophora glabripennis）攻击看似健康的树木，因此需要更有效的工具来对其进行测量和监视。为了更好地了解甲虫如何识别和定位其寄主，我们比较了成年甲虫（Acer negundo）（首选寄主），柳柳（Salix matsudana），臭椿（Ailanthus altissima）和松果（Pinus bungeana）的取食和定向，发现成虫比其他人更喜欢甲虫。然后，我们评估了颜色提示是否增强了寄主（A. negundo）气味对A. glabripennis的吸引力。我们评估了成年A. glabripennis的偏好用于模仿切下的树枝的树皮的颜色，并发现成虫被深绿色吸引。我们仅检查了植物气味的影响，发现被测植物之间没有显着差异。然而，与其他颜色与A. altissima和P. bungeana气味的组合相比，深绿色和A. negundo气味的组合对成年人更具吸引力。最后，我们研究了颜色和气味之间的相互作用，以确定它们对A. glabripennis行为的潜在影响。我们发现，包括森林绿色和宿主气味在内的线索组合对成年人比其他成年人更具吸引力，但成年人对森林绿色的偏好受到了破坏A. altissima的气味。
