Abstract: Objective To assess the risk of Anopheles barbirostris invading China under future climate change scenarios, and to provide a basis for monitoring and early warning. Methods The maximum entropy model was used to predict the recent global potential distribution and project the future potential distribution of An. barbirostris in China. The main environmental factors affecting the distribution of An. barbirostris were analyzed based on the contribution rate of environmental factors. The vector risk assessment index system was established to calculate the comprehensive risk value of invasive species. Results A total of 99 effective distribution points of An. barbirostris were identified. The rainfall in September played a leading role in affecting the distribution of potential suitable areas of An. barbirostris. The omission rate of model training was roughly the same as the theoretical omission rate, and the area under the receiver operating characteristic curve was 0.988. Under the current climate scenario, the potential suitable areas of An. barbirostris in China were mainly in Guangdong province, Guangxi Zhuang Autonomous Region, and Hainan province as well as the eastern Sichuan Basin. In 2081-2100, China has the largest potential suitable area (207.51×104 km2) under the shared socioeconomic pathway 585 climate scenario, and the area of suitable area will show an increasing trend under various climate scenarios. Through the risk assessment index system, it was calculated that the comprehensive risk value of An. barbirostris was 0.57, so An. barbirostris belonged to the medium-risk invasive species. Conclusions An. barbirostris is a species with a medium invasion risk. In the future, the mosquito vector surveillance system should be improved according to the distribution of its suitable areas, and scientific prevention and control strategies should be formulated.

摘要: 目的 评估未来气候变化情景下须喙按蚊入侵中国的风险,为监测预警提供依据。方法 使用最大熵模型预测须喙按蚊近期在全球的潜在分布状况和预估未来在中国的潜在分布区变化趋势。基于环境因子的贡献率,分析影响须喙按蚊分布的主要环境因子;构建病媒生物风险评估指标体系用于计算入侵物种的综合风险值。结果 共筛选出须喙按蚊有效分布点99个;9月降雨量在影响须喙按蚊潜在适生区分布中占有主导作用;模型训练遗漏率与理论遗漏率大体一致,受试者工作特征曲线下面积(AUC)值为0.988;当前气候情景下,须喙按蚊在中国的潜在适生区主要集中在广东、广西、海南省(自治区)以及四川盆地东部等;须喙按蚊在未来2081-2100年共享社会经济路径(SSP)585气候情景下中国的潜在适生区范围最广(207.51×104 km2),未来各气候情景下适生区面积呈增加趋势;通过风险评估指标体系,计算得出须喙按蚊的综合风险值为0.57,属于中等入侵风险物种。结论 须喙按蚊在中国属于中等入侵风险物种,未来应根据其适生区分布情况完善蚊媒监测系统,制定科学的防控策略。
