Abstract： Dendroctonus frontalis Zimmermann is one of the most economically important pests of Pinus plantations in America. Based on the biology of D. frontalis and climate data, potential suitable habitat for D. frontalis in China was predicted using CLIMEX and ArcGIS. The results show that D. frontalis has a wide potential distribution in China. Predicted optimum areas for establishment were most of north and southwestern China, including Shandong, Henan, Shanxi, Anhui, Shanxi, Hubei, Sichuan, Yunnan.
