Eucryptorrhynchus scrobiculatus (Coleoptera:Curculionidae) is an important pest in China that specifically damages Ailanthus altissima (Mill.) Swingle (Sapindales: Simaroubaceae). Trembler grid lamps and food attractant traps frequently were used to monitor and control E. scrobiculatus; however, the effect of these methods is poor in actual application. The purpose of this study was to develop a new monitoring method. Traps of seven colors and two shapes were compared with respect to the attraction of E. scrobiculatus adults, and a field trapping test was performed. We found that E. scrobiculatus adults were most sensitive to red (16.11 ± 7.72) and black traps (14.44 ± 8.07) and to tall vertical black shapes in the laboratory. In the field, red (70.50 ± 5.74) and black traps (60.75 ± 8.22) were most effective at catching E. scrobiculatus, and traps with color and attractant still were more attractive to E. scrobiculatus than traps with colors only. These results provide a reference for monitoring E. scrobiculatus adults.
豆象（Coleoptera:Curculionidae）是中国的一种重要害虫，专门危害樗树（Sapindales:Simaroubaceae）。震动诱捕灯和食物诱捕器常用于监测和控制豆象，但在实际应用中效果不佳。本研究旨在开发一种新的监测方法。比较了七种颜色和两种形状的诱捕器对豆象成虫的吸引力，并进行了野外诱捕试验。结果表明，豆象成虫对红色（16.11 ± 7.72）和黑色诱捕器（14.44 ± 8.07）最敏感，在实验室中对高大垂直的黑色形状最敏感。在野外，红色（70.50 ± 5.74）和黑色诱捕器（60.75 ± 8.22）对豆象的诱捕效果最佳，且具有颜色和引诱剂的诱捕器比仅具有颜色的诱捕器对豆象更具吸引力。这些结果为监测豆象成虫提供了参考。
