摘　　要：在内蒙古巴彦淖尔市杨树人工防护林区，采用杨树高枝截干是防治光肩星天牛Anoplophora glabripennis（Motschulsky）的有效手段之一。但在当年春季杨树截干上留下的机械伤口及新萌发枝条，为白杨透翅蛾Paranthrene tabaniformis（Rott.）的入侵提供了有利条件。白杨透翅蛾在1-3年的截干上发生密度较高，严重时影响到新萌发枝干的生长甚至死亡。2007年5月调查发现，在杨树截干上白杨透翅蛾的有虫株率达到89.17％，平均虫口密度达到（3.40±0.21）头／株，远远超过了0.3头，株的最低防治标准。最后，结合当地杨树人工防护林网的特殊环境条件，提出了针对性的防治措施。In Bayannaoer City of Inner Mongolia Autonomous Region, top trunk-cutting technique was one of the effective methods for controlling Asian longhorned beetle Anoplophora glabripennis （Motsch.） （Coleoptera： Cerambycidae） in poplar shelter plantation. However, the new mechanical wounds and the sprouts of the poplar stump were easily infested by the poplar clearwing moths Paranthrene tabaniformis（Rott.） （Lepidoptera： Sesiidae ） in spring. In one-to three-year-old poplar stumps and sprouts, the pest was found at high population density. Furthermore, the poplar stumps and sprouts would be dead under severe infestation. In May of 2007, 89.17% of poplar stumps were infested by P. tabaniformis and the population density was 3.40±0.21 larvae in each poplar stump on average. It was much higher than the lowest controlling standard （0.3 larvae per tree）. At last, the researcher suggested specific strategy for controlling P. tabaniformis based on the special environment in poplar shelter plantation.
