入侵昆虫西花蓟马的潜在适生区分析

Analysis of potential distribution of the invaded insect Frankliniella occidentalis (Pergande)(Thysanoptera: Thripidae) in China

本文在分析西花蓟马生物学特性及其世界分布的基础上,采用CLIMEX软件及提供的气候匹配性分析和位置比较分析两种分析模型,结合我国634个气象站点的数据,预测西花蓟马在我国的潜在分布区。结果表明,西花蓟马在生态气候指数EI≥3的地区爆发危害风险性较大。西花蓟马在我国的广东、海南、安徽、福建、江苏、山东、广西、贵州、河南、湖北、陕西、四川、云南、重庆等省市具有广泛的适生区;其适宜生存的北界分布在中国年平均温度10℃等温线、1月份平均温度-8℃等温线以及年平均极端最低温度-20℃等温线附近;而新疆、青海、西藏、黑龙江、吉林、辽宁、内蒙古等省或自治区为不适应生存区。

Based on the information of daily climatic records of 634 stations in China and the biological characteristics and distributions of FranklinieUa occidentalis （Pergande） in the world, the potential distribution areas of F. occidentalis in China were analyzed with the models of Match Climates and Compare Locations of the software CLIMEX. The results showed that F. occidentalis could prevail in Guangdong, Hainan, Anhui, Fujian, Jiangsu, Shandong, Guangxi, Guizhou, He＇ nan, Hubei, Shaanxi, Sichuan and Yunnan provinces and Chongqing city, but was unable to survive in Xinjiang, Qinghai, Tibet, Heilongjiang, Jilin, Liaoning, and Inner Mongolia provinces or autonomous regions in the northeast and northwest of China. The north limit of its distribution in China was located along the joining line of such cities as Weihai, Yantai, Ji＇nan, Dezhou, Xingtai, Yuncheng, Xi＇ an, Baoji and Tianshui, where the annual average temperature is 10℃, the average temperature in January - 8 ℃, and the annual extremely lowest temperature - 20℃.
