In Bayannaoer City of Inner Mongolia Autonomous Region, top trunk-cutting technique was one of the effective methods for controlling Asian longhornedbeetle Anoplophora glabripennis (Motsch.) (Coleoptera: erambycidae) 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 infestatio
n. 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.
