Pinus sylvestris is one of the pine tree branches big pests, the main hazards Pinus tabulaeformis, Pinus sylvestris and other tree species. After the damage caused by pine snipehead, it will affect the growth and the quality of the trees and cause serious economic losses. In the southern part of Zheli League, Naiman Banner, Kulun Banner and Houqi Artificial Pinus tabulaeformis forests all suffered from pine needles. Due to the inconvenient traffic and lack of water in mountainous areas, it was difficult to carry out chemical control. In view of the need of prevention and control of production, we conducted a special study on the prevention and control of Pinus tabulaeformis in Qinglongshan Forest Farm in Naiman Banner since 1980. First, the host and the damage of pinehoppers (Dioryctria splenaiaella H.S) is a Lepidoptera Pyralidae family, located in northeastern China, North China, West
