Abstract:

Through field survey and a review of the relevant literature, the basic biological information about Carpomya veusuviana was collected. The suitability analysis software, CLIMEX and GARP, combined with ArcGIS were used to analyze and predict the potential geographic distribution of C. veusuviana in China. The integrating analyses results shows there is a wide potential distribution for C. vesuviana. The primary suitability regions include the most parts of Xinjiang, Gansu, Inner Mongolia, Ningxia, Sichuan, Yunnan, Shaanxi, Shanxi, Hebei, Beijing, Tianjin, Henan, Liaoning, Shandong, Jiangsu, Anhui, Hubei, Hunan, Jiangxi, Fujian, Guangxi, Guangdong, Hainan. The secondary suitability regions include north and south Xinjiang,eastern part of Linhe in Inner Mongolia, south Ningxia, part of Gansu next to Xinjiang and the transect districts of Sichuan, Gansu and Shaanxi, Geermu City and Dulan County of Qinghai, north Shanxi, north Hebei, part of Jilin next to Inner Mongolia and Liaoning, the middle parts of Sichuan, eastern parts of Chongqing, Motuo County and Chayu County and Cuona County of Tibet, West Hubei, West Hunan, north Guizhou, north Zhejiang, north Guangxi, north Guangdong, west Taiwan. According to the quantitative methods of the pest risk analysis, the risk level of C. vesuviana to the different regions in China was evaluated. The result shows that C .vesuviana is a highly dangerous pest to jujube in China. It will potentially threaten the development of jujube in China.
