1998年 8月 1 2～ 2 0日 ,在中国林业科学研究院院内杨树林树高 3m处放置粘性诱捕器 ,内放人工合成的柳毒蛾诱剂内芯 3Z-cis-6 ,7-cis-9,1 0 -Di-epoxy-heneicosene,每天上午检查一次。在杨毒蛾 L eucoma candida Staudinger种群密度很低的情况下 ,9天共诱捕雄成虫 2 1头。试验结果表明 ,该信息素对杨毒蛾确有引诱作用 ,为进行监测和防治提供了有效途径 On August 12-20, 1998, a sticky trap was placed 3m above the height of the poplar tree in the Chinese Academy of Forestry, and the artificial core of 3Z-cis-6, 7-cis-9 , 1 0 -Di-epoxy-heneicosene, check every morning. In the case of L. eucoma candida Staudinger population density was very low, 21 male adults were traced for 9 days. The test results show that the pheromone has temptation to T. grisea, which provides an effective way for monitoring and control
