Abstract: The potential geographic distribution of Phenacoccus solani in China was predicted in BIOCLIM mode and the prediction was evaluated by ROC. The results showed that the prediction should be reliable, and P. solani could colonize in most parts of China. The high probable occurrence areas covered Huanghuai region, Jianghuai region and the lower-middle reaches of Yangtze-river basin, including provinces of Hainan, Guizhou, Sichuan, Guangxi, Guangdong, Hunan, Hubei, Henan, Hebei, Anhui, Jiangxi, Fujian, Zhejiang. Other probable occurrence areas involved southwest, northwest and northeast of China, including Yunnan, Xinjiang, Tibet, Gansu, Ningxia, Inner Mongolia, Shaanxi, Liaoning.

Key words: Phenacoccus solani, geographical distribution, BIOCLIM model
