| Abstract: | The preliminary forecast formula of occurrence stage of Dendrolimus houi was put forward by means of development rate and stage distance. The preliminary forecast formula of harm extent was also developed on the basis of insect plague progression table of Dendrolimus houi . The results will provide scientific basis for deciding better control time and whether demanding control or not as well as how to control. |
