摘　　要：目的:柳毒蛾是沙柳的主要害虫之一,在暴发期能短时间内吃光叶片,严重影响沙柳的生长。该研究旨在研制出一种对柳毒蛾有效的引诱剂,以期为柳毒蛾的野外监测和科学控制提供理论依据。方法:利用4个性引诱剂、5种高度以及不同天气条件对柳毒蛾进行引诱试验。结果:4个性引诱剂中:C(3Z-cis-6,7-cis-9,10-Diepoxy-heneicosene∶二十烷∶十八炭二烯酸∶二十四烷=40∶1∶1∶1)对柳毒蛾的引诱效果最好,诱捕器的悬挂高度为1.2m和1.6m时对柳毒蛾的引诱效果较好。在不同天气条件下,晴天对柳毒蛾的引诱效果要明显优于阴天和雨天。结论:性引诱剂C(3Z-cis-6,7-cis-9,10-Diepoxy-heneicosene∶二十烷∶十八炭二烯酸∶二十四烷=40∶1∶1∶1)在晴天情况下,将诱捕器悬挂于大约1.2m或1.6m处时,是引诱柳毒蛾最理想的组配。Leucoma salicisis one of the main pests on Salix psammophila.The moth could eat up the leaves in a short time in the outbreak period,which seriously affected the growth of S.psammophila.The purpose of this study is to develop an effective attractant for L.salicis and provides a theoretical basis for its field monitoring and scientific control.Four kinds of attractants,five heights and different weather conditions were used to measure the attractiveness of L.salicis.Among the four kinds attractants,C(3 z-cis-6,7-cis-9,10-diepoxy-heneicosene:eicosane:octadecadienoic acid:24 ane=40∶1∶1∶1)had the best attractant effect on the moth adults,while traps installed at the heights of 1.2 m and 1.6 m had the better effect for the moth adults Under different weather conditions,The attractive effect of sunny days to the moth was better than cloudy days and rainy days.Inconclusion,it was the best condition to lure L.salicis that the sex attractant C(3 z-cis-6,7-cis-9,10-epoxy-heneicosene∶eicosane∶octadecanedioenoic acid∶24 ane=40∶1∶1∶1)was installed at about 1.2 m or 1.6 m on a clear day.
