Aedes sierrensis在中国的潜在分布预测

Potential distribution of Aedes sierrensis in China

目的预测Aedes sierrensi(sLudlow,1905)在我国的潜在分布。方法根据文献资料整理得出Ae. sierrensis稳定分布,应用预设预测规则的遗传算法(GARP)生态位模型对其在中国的潜在分布进行分析预测。结果Ae. sierrensis在我国的潜在分布区涉及大部分省(直辖市、自治区),高风险地区集中在我国中北部地区,包括新疆、内蒙古、宁夏、陕西、山西、河北、北京、天津、河南、山东、辽宁、吉林和黑龙江省(直辖市、自治区);中度适生区集中在安徽、河北南部、山东西南部、湖北北部、浙江西北部等地区;低度适生区集中在贵州、广西、湖南、重庆、湖北、江西、福建、台湾、海南等省(自治区)。结论Ae. sierrensis在我国潜在分布区广,风险等级高,应及时制定相应风险管理措施,严防该蚊入侵我国。

Objective To predict the potential distribution of the Western Treehole Mosquitoes, Aedes sierrensis （Ludlow, 1905） in China. Methods Genetic algorithm for rule-set production （GARP） was used for prediction of the potential distribution based on current stable distribution of Ae. sierrensis derived from previous literatures. Results The potential distribution of Ae. sierrensis covered most provinces in China, with the high-risk area located in the north and central part of China, including Xinjiang, Inner Mongolia, Ningxia, Shaanxi, Shanxi, Hebei, Beijing, Tianjin, Henan, Shandong, Liaoning, Jilin and Heilongjiang; the moderate-risk areas including Anhui, south of Hebei, southeast of Shandong, north of Hubei and northwest of Zhejiang; and the lowrisk areas including Guizhou, Guangxi, Hunan, Chongqing, Hubei, Jiangxi, Fujian, Hainan and Taiwan. Conclusion Extensive potential distribution ofAe. sierrensis was identified in China with high risk levels, and thus risk management should be developed and deployed to prevent potential invasion of such mosquitoes.
