集约经营杨树人工林中光肩星天牛不成灾原因的探讨

A RESEARCH FOR THE OCCURENCE OF ANOPLOPHORA GLABRIPENNIS (MOTSCHULSKY) IN THE POPLAR INTENSIVE MANAGEMENT PLANTATION

光肩星天牛Ａｎｏｐｌｏｐｈｏｒａｇｌａｂｒｉｐｅｎｎｉｓ，（Ｍｏｔｓｃｈｕｌｓｋｙ）分布于国内大部分省区。山东绝大多数个体（约占９０％）１年１代，少量个体（约占１０％）３年２代（即１年１代和２年１代交替进行），以卵、卵态幼虫和幼虫越冬。成虫有啃食嫩枝...

The population of the glabrous spotted willow borer declines rapidly in the NAP popular intensive management plantations and the damage to farmland sheltbelts, fourside scattered grown trees and different clone plantations was got through the fixed location monitoring in Shandong Province. The result indicated that the reasons made the population of the borer declining rapidly in the intensive managed stands are the rotation period shortening eliminating pest source stands, variaties changing fast and various clones planting refraining the adaptability of the borer to poplar clones, the environmental conditions of plantations and intensive management measures destroying the suitable surroundings of the borer's reproduction and growth. The community of the borer was controlled at the lower level in NAP poplar intensive management plantations in Shandong Province.
