摘　　要：湿地松粉蚧Oracella acuta(Lobdell)Ferris是我国植物检疫性有害生物之一,危害马尾松、湿地松、火炬松等松属植物。本文基于中国820个气象站点的气象数据、湿地松粉蚧的生物学数据和已知分布资料,结合CLIMEX模型与ArcGIS软件对湿地松粉蚧在我国的潜在分布区进行了预测。结果表明,湿地松粉蚧在我国的适生区主要分布在3.85°N-39.90°N之间,适生面积占全国国土总面积的38.79%。目前主要寄主植物分布的省份其气候条件均适合于湿地松粉蚧的生存,因此它们都是潜在的分布和适生区。高风险区主要包括台湾、海南、贵州、重庆、江苏和上海;广东、广西、云南、陕西、河南、安徽、湖北和河南的大部分地区以及福建南部、山东南部、湖南北部、浙江东部和四川东部。基于本研究中湿地松粉蚧在我国的适生性分析结果,尤其针对中高风险区域,应加强湿地松粉蚧检疫措施,完善监测体系,防止其进一步的扩散传播。The mealybug Oracella acuta （Lobdell） Ferris, is one of the quarantine pests which may cause huge damage to Pinus massoniana Lamb, P. elliottii Engelm. , P. taeda L. in China, 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 climate - suitable for survival of O. acuta, and therefore potentially favorable for distribution and expansion of this species. 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 that quarantine and monitoring measures should of Hunan, east of Zhejiang, and Sichuan. We suggest be improved and to better prevent the spread and expansion of O. acuta in China.
