摘要
自2000～2003年,对东北三省57个县、市的光肩星天牛发生动态进行了实地调查,新发现5个光肩星天牛分布点,即牡丹江、大安、吉林、德惠和磐石.目前东北地区光肩星天牛猖獗危害区在四平以南,四平以北主要沿京哈线向北延伸,分布北界已扩展到哈尔滨,与20 a前相比向北扩展了2个纬度,京哈线两侧呈点状分布.传播途径主要是人为因素.应尽快采取措施压低发生点的虫口密度,控制其外传.
From 2000 to 2003, on - the - spot investigations on the occurrence dynamics of Anoplophora glabripennis were conducted in 57 counties or cities from three provinces of Liaoning, Jilin and Heilongjiang in the Northeast of China. Another five distribution regions, Mudanjiang, Da＇an, Jilin, Dehui and Panshi, were found for the first time. Presently, the rampant harming region of the pest in Northeastern China is to the south of Siping City. However, to the north of Siping City, the pest spreads northward along Beijing - Harbin railway line, and has reached to Harbin. Anoplophora glabripennis was found two degrees north in latitude compared with its distribution 20 years ago, and showed a spot distribution pattern along Beijing - Harbin railway line. The major spreading factor of the pest is human activities. So control measures are urgently needed to reduce its density to a lower level, and put a curb on its outward spread.
