[Objectives]  Although it has yet to establish in China, Ips grandicollis is one of the country’s most important quarantine forest pests. In recent years, the risk of it establishing has risen due to the increased amount of imported timber. Predicting potentially suitable habitat for this species is therefore timely as this will allow quarantine, prevention, and control, operations to be targeted more efficiently if required. [Methods]  Climate similarity analysis methods using DIV-GIS and SPSS software tools were used to predict suitable I. grandicollis habitat in China. Nineteen bioclimatic variables that could influence the establishment of I. grandicollis were first analyzed with SPSS and six key variables identified. DIV-GIS was then used to analyze these key variables and predict suitable I. grandicollis habitat. [Results]  Globally, the most suitable I. grandicollis habitat is mainly in mid-eastern North America, mid-eastern South America, mid-eastern Europe, the mid-south and eastern coastal areas of Africa, central and eastern coastal areas of Asia, and coastal regions of Australia. In China, the most suitable habitat is mainly in the mid-south of Shandong, Henan, Hubei and Chongqing. Analytical method and predicted results are discussed and advice given for the quarantine, prevention and control of I. grandicollis. [Conclusion]  Relevant departments should reinforce quarantine and monitoring measures for I. grandicollis because the ports importing the wood of host trees of this species are all located in regions with predicted suitable habitat.
