Forest diseases and pests are perceived as a growing hazard to China economy. It is a common conclusion that the actualities of forest pests in china are no effective measures to the old important pests, some secondary pests are ascending to chief pests, increasing devastation from exotic pests, frequent ecological pest eruption induced by environmental detriment and host-leading diseases to threaten the "Western Development Project "in China, which is the most important economical strategy to China; th...
Forest diseases and pests are perceived as a growing hazard to China economy. It is a common conclusion that the actualities of forest pests in china are no effective measures to the old important pests, some secondary pests are ascending to chief pests, increasing devastation from exotic pests, frequent ecological pest eruption induced by environmental detriment and host-leading diseases to threaten the 'Western Development Project 'in China, which is the most important economical strategy to China; that inducement of current forest pests results from ecological function loss and dangerous exoticpest intruding, On the basis of these cognitions, we suggest that strategies of management pests to natural forest would be stressed to maintain its innate capacities to adjust pests in virgin forest and resume such function in intermpted one, that to artificial forest would establish self-control in afforestated stands and develop resistant tree varieties and species, especially those in landscape trees. In research, the management principals and techniques based on ecological and gene science should be considered to study. The general purpose and essential task of research on forest pest in China are to construct basie principles for sustainable management on forest diseases and pests and to achieve key techniques for meeting such management needs.
