In order to explore an effective way to prevent and cure pine caterpillars in the southern mountainous area of Chifeng, Pine Forest Station of Ningcheng County and Forest Prevention Station of Chifeng City set up 12000 mu of pine caterpillar population in Huadunliang Work Area, Zhonglin Forest Farm, Control of experimental forest. After five years of governance, in late July 1986 passed the acceptance. This experiment is based on “silviculture measures, taking biological control as the leading factor, taking biological, physical, chemical and other integrated measures to control the pine caterpillars at an undiscovered level” for the purpose of comprehensive planning of experimental forest land, For a single
