光肩星天牛Anoplophora glabripennis(Motsch.)是杨树的主要蛀干害虫之一,在我国杨树分布区都不同程度地遭到该虫的为害,以农田防护林和四旁树木受害最严重,在华北中原地区甚至成了发展杨树的主要障碍。近几十年来随着害虫综合管理的提出,虽然各地对光肩星天牛的生物学特性及防治等进行了多方面的探索和研究,并取得不少成果,但为了更有效地控制害虫,1980年至1982年我们就不同杨树品种对光肩星天牛的抗性问题,做了调查研究,现整理如下:
Anoplophora glabripennis (Motsch.) Is one of the major stem borers of poplar. It was damaged to varying degrees in poplar areas in China. The shelterbelts and four sides of the trees suffered the worst damage. In northern China, the Central Plains even Become the main obstacle to the development of poplar. In recent decades, with the proposal of integrated pest management, many aspects have been explored and studied and many achievements have been made in the biological characteristics and prevention and control of Anoplophora glabripennis. In order to control the pests more effectively, from 1980 to 1982 Years we are different varieties of poplar on the light Shibei resistance, did a survey, are now organized as follows:
