Abstract:

 Based on the information of daily climatic records of 634 stations in China and the biological characteristics and distributions of Frankliniella occidentalis (Pergande) in the world, the potential distribution areas of F. occidentalis in China were analyzed with the models of Match Climates and Compare Locations of the software CLIMEX. The results showed that F. occidentalis could prevail in Guangdong, Hainan, Anhui, Fujian, Jiangsu, Shandong, Guangxi, Guizhou, He'nan, Hubei, Shaanxi, Sichuan and Yunnan provinces and Chongqing city, but was unable to survive in Xinjiang, Qinghai, Tibet, Heilongjiang, Jilin, Liaoning, and Inner Mongolia provinces or autonomous regions in the northeast and northwest of China. The north limit of its distribution in China was located along the joining line of such cities as Weihai, Yantai, Ji'nan, Dezhou, Xingtai, Yuncheng, Xi'an, Baoji and Tianshui, where the annual average temperature is 10℃, the average temperature in January -8℃, and the annual extremely lowest temperature -20℃.

Key words: Frankliniella occidentalis, biological invasion, suitable distribution area, climate matching, location comparison
