Abstract: Objective To investigate the population composition, density, and seasonal variation of vectors in Hubei province, China, in 2018, and to provide scientific evidence for vector control. Methods The night trap method was used to capture rodents in odd months during January to December; mosquitoes were captured using the light trap method, Breteau index method, and double net method from April to October; flies were caught using the cage trapping method from April to October; the sticky trap method was used to capture cockroaches in odd months during January to December. Results In 2018, the rodent capture rate in Hubei province was 0.36%, and Rattus tanezumi was the dominant species; the density of rats in rural villages and special industries was slightly higher than that in the urban residential areas. The result of mosquito light trap surveillance showed that the mean density of mosquitoes was 12.44 mosquitoes/lamp·night, and Culex pipiens quinquefasciatus was the dominant species; the density of mosquitoes in livestock sheds was significantly higher than that in other habitats. The density of flies was 2.55 flies/cage, and Musca domestica was the dominant species; farmers' markets had the highest fly density (3.95 flies/cage). The mean density of cockroaches was 0.53 cockroaches/trap, and the infestation rate was 7.64%; Blattella germanica was the dominant species; farmers' markets had the highest cockroach density (1.93 cockroaches/trap) and infestation rate (14.44%). Rodents and cockroaches were active throughout the year, and mosquitoes and flies maintained a relatively high density level from May to September. Conclusion The densities of main vectors in Hubei province were at a low level in 2018. The sensitivity of surveillance systems and the level of monitoring, forecasting, and early warning should be continuously improved in the future, so as to provide scientific evidence for the prevention and control of vectors in Hubei province.

摘要: 目的 了解2018年湖北省病媒生物种群构成、密度及季节消长规律,为病媒生物防控提供科学依据。方法 鼠类监测采用夹夜法,1-12月单月监测;蚊虫监测采用诱蚊灯法、布雷图指数法和双层叠帐法,4-10月监测;蝇类监测采用笼诱法,4-10月监测;蜚蠊监测采用粘捕法,1-12月单月监测。结果 2018年湖北省鼠类捕获率为0.36%,黄胸鼠为优势种,农村居民区和重点行业鼠密度略高于城镇居民区。诱蚊灯法监测结果显示,蚊类平均密度为12.44只/(灯·夜),致倦库蚊为优势种,牲畜棚蚊密度显著高于其他生境。蝇类密度为2.55只/笼,家蝇为优势种,农贸市场蝇密度最高(3.95只/笼)。蜚蠊平均密度为0.53只/张,侵害率为7.64%,德国小蠊为优势种,农贸市场蜚蠊密度(1.93只/张)和侵害率(14.44%)均为最高。鼠类和蜚蠊全年均有活动,蚊、蝇在5-9月维持在较高密度水平。结论 湖北省2018年主要病媒生物危害均处于较低水平,今后应持续提升监测系统敏感性,提高监测与预测预警水平,为湖北省病媒生物防制提供科学依据。
