我们于1980年8月和11月底至12月初,曾对汉中和安康两个地区光肩星天牛Anoplophora glabripennis(Motschulsky)为害杨树的情况进行了调查。现将调查简况整理如下:1970年以来,汉中和安康两个地区在公路、渠道、村庄附近,普遍栽植了大量的大宫杨、欧美杨等杨树,使四旁绿化工作得到迅速发展。在初植几年由于加强了管护,杨树生长健壮。但在近年来对管护工作放松了,特别是对光肩星天牛的防治工作没有引起足够的重视,导致了这一害虫的猖獗发生。目前,两地区的大官杨和欧美杨正处于毁灭状态中。
In August 1980 and the end of November to the beginning of December 1980, we investigated the situation of poplars damaged by Anoplophora glabripennis (Motschulsky) in two areas, Hanzhong and Ankang. The survey is now organized as follows: Since 1970, Hanzhong and Ankang have planted a large number of Populus euphratica, Populus euphratica and poplar trees in the vicinity of highways, roads and villages in two areas around the country, resulting in the rapid development of afforestation on all sides. In the early planting a few years due to strengthening management and protection, poplar grow robust. However, the relaxation of the management and protection work in recent years has not given enough attention to the prevention and control of Anoplophora glabripennis, which has led to the rampant occurrence of this pest. At present, the chief officers Yang and Ouyang in the two regions are in a state of destruction.
