杨毒蛾(Lecoma Candida Staudmger)是白城地区重要的食叶害虫之一。近几年,在我市机械林场发生面积达50000余亩,给林木生长造成严重的威胁。对杨毒蛾的虫情调查,过去一直采取蹲树根“眼瞧、手抓、口数”的方法,调查准确度只有60—70%,而且费工费时,容易贻误防虫时机。为此,我们在1986年春季的虫情调查中,采用抹胶的方法对杨毒蛾进行了调查。现将试验情况报告如下:

Lecoma Candida Staudmger is one of the important foliar pests in Baicheng area. In recent years, the mechanical forest farm in our city has an area of ​​more than 50,000 mu, which poses a serious threat to the growth of trees. In the past, we have taken the method of “seeing, grasping, and counting” the root of the squatting tree. The investigation accuracy is only 60-70%, and it is easy to delaying the time for insect control when it takes time and effort. To this end, we surveyed the insects in the spring of 1986 with the method of plastering. The test report is as follows:
