Abstract: Objective To investigate the species, density, and seasonality of main vectors in Jiangxiyan, a world heritage irrigation structure in Longyou County, Zhejiang Province, China, so as to provide a scientific basis for the prevention and control of vector-borne infectious diseases.Methods According to the Zhejiang Provincial Vector Surveillance Program, rodents, mosquitoes, and ticks were monitored at Jiangxiyan in Longyou County from 2019 to 2021. Rodents were monitored by night snap trapping, adult mosquitoes by lamp trapping, larval mosquitoes using the Breteau index (BI) method, and ticks by flag dragging and animal body surface collection. The density, species composition, and seasonal trends of vectors in different habitats were analyzed by using the descriptive epidemiological methods.Results At Jiangxiyan in Longyou County from 2019 to 2021, the overall rodent density was 4.05%, and Apodemus agrarius was the dominant species, accounting for 41.53% of the total number. A total of 118 mouse lungs were tested, with a positive rate of 2.54% for Hantavirus antigen; The positive rate of Hantavirus antibody in 118 mouse blood samples was 3.39%. Culex pipiens pallens/quinquefasciatus was the dominant mosquito species, accounting for 76.11%, followed by Cx. tritaeniorhynchus, Anopheles sinensis, and Aedes albopictus. The average BI from 2019 to 2021 was 27.25. No ticks were caught.Conclusions A. agrarius is the dominant rodent species, Cx. pipiens pallens/quinquefasciatus and Ae. albopictus are the dominant mosquito species at Jiangxiyan. Targeted comprehensive control measures should be taken to control the spread of vector and vector borne infectious diseases.

摘要: 目的 了解浙江省龙游县姜席堰主要病媒生物种类、密度和季节消长趋势,为病媒生物传染病防控提供科学依据。方法 按照《浙江省病媒生物监测方案》要求,2019-2021年在龙游县姜席堰开展鼠类、蚊类和蜱监测,其中鼠类监测选用夹夜法。成蚊监测选用诱蚊灯法,幼蚊监测采用布雷图指数(BI)法;蜱选用布旗法和动物体表检蜱法。采用描述流行病学方法统计分析不同生境的病媒生物密度、种类构成和季节消长趋势。结果 2019-2021年龙游县姜席堰鼠总密度为4.05%,优势鼠种为黑线姬鼠,占41.53%。共检测鼠肺118份,汉坦病毒抗原阳性率为2.54%;鼠血118份,汉坦病毒抗体阳性率为3.39%。蚊类监测优势种为淡色/致倦库蚊,占76.11%,其次为三带喙库蚊、中华按蚊和白纹伊蚊,2019-2021年平均BI值为27.25。未捕获到蜱虫。结论 姜席堰以黑线姬鼠为优势鼠种,淡色/致倦库蚊为优势蚊种,应有针对性地采取综合防控措施控制病媒生物及相关传染病的传播。
