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. |
