This paper provided a brief introduction including its morphology, host plants, geographical distribution and spread mode. The potential distribution of Phenacoccus manihoti analyzed by CLIMEX mode showed that South of China, Yunnan, Guizhou, Hunan, Jiangxi, Zhejiang, Sichuan, Chongqing, Hubei, Anhui and Shanghai were all the suitable areas of that pest. It was very important to forecast and monitor the pest’s invasion.
