| Abstract: | Research progress in economic thresholds of several major forest pests such as Dendrolimus punctatus Walker,Anoplophora nobilis Ganglbauer and Gravitarmata margarotana(Hein) are discussed extensively from the aspects of endangered position,tree species harmed by forest pests,locations of pest damage occurrence and control indexes.Practical pest control indexes in different areas are suggested and two method,for the study of economic threshold,i.e.,simulative and direct pest harming are concluded. |
