杨卷叶麦蛾(Auacampsis populella Cieck)是山西省北部地区杨树叶部主要害虫之一。近年来,受害程度日趋严重,1978年大同御河林场小叶杨人工林成灾面积达3万余亩,其中3千余亩濒于死亡。为此,我们于1978—1979年在大同、朔县、太原等地,对该虫进行了初步研究,并进行了大面积的防治,现将初步结果整理如下。 Au coil (Populella Cieck) is one of the major pests of poplar leaves in the northern part of Shanxi Province. In recent years, the degree of victimization has become increasingly serious. In 1978, the disaster-affected area of ​​Populus simonii plantation in Datong Yuhe Forestry Center reached more than 30,000 mu, of which more than 3,000 acres were dying. To this end, we conducted a preliminary study of the pest in Datong, Shuoxian, Taiyuan and other places during 1978-1979 and carried out large-scale prevention and treatment.
