| he mealybug Oracella acuta (Lobdell) Ferris, is one of the quarantine pests in China, which may cause huge damage to Pinus massoniana Lamb, P. elliottii Engelm., P. taeda L. and other pine species. The potential geographic distribution of O.acuta were predicted using CLIMEX and ArcGIS, as well as the available biological data, documented distribution of O. acuta and meteorological data from 820 weather sites in China. The results showed that the potential geographic distribution area ranged between 3.85°N and 39.9°N, which accounts for 38.7% of the country’s total area. The areas with Pinus plants are all favorable for the distribution of O. acuta. The highly suitable areas involve Taiwan, Hainan, Guizhou, Chongqing, Jiangsu, Shanghai, most parts of Guangdong, Guangxi, Yunnan, Shaanxi, Henan, Anhui, Hubei, Henan, south of Fujian, Shandong, north of Hunan, east of Zhejiang, and Sichuan. We suggest that quarantine and monitoring measures should be improved and to better prevent the spread and expansion of O. acuta in China. |
