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.
