一、前言杨树在河北地区,繁殖容易、生长迅速、适应性强,是绿化、造林和园林化的重要树种之一。但近年来由于白杨透翅蛾的猖獗为害,致使大量苗木和幼树受风吹而折断,直接影响了苗木的产量和幼树的速生。为了掌握其生活史,寻找有效的防治方法,我们于1958—1959年首先在河北地区对此虫的发生及为害情况进行了初步调查,于1960—1962年在唐山专署农林局海滨林场对此虫的生活史、习性等进行了较全面的观察,并进行了防治试验,现将结果加以整理报导,以供参考。

In recent years, however, as a result of rampant poplar moth’s rampant damage, a large number of seedlings and saplings are severely damaged by the wind and have a direct impact on the yield of seedlings and the rapid growth of saplings. In order to grasp their life history and find effective methods of prevention and treatment, we conducted a preliminary investigation of the occurrence and damage of this pest in Hebei from 1958 to 1959. From 1960 to 1962, we studied the pests at the Haibin Forest Farm of Agriculture and Forestry Bureau of Tangshan Life history, habits and so on a more comprehensive observation, and conducted a prevention and treatment test, the results are now reported for reference.
