Abstract: Objective To provide scientific data for vector control after investigating its community structure and seasonal fluctuations of vectors in Guangxi Zhuang Autonomous Region in 2016. Methods Mouse trap, light trap, cage trap and glue trap were used to catch rodents, mosquitoes, flies and cockroaches, respectively, in Guilin and Beihai cities in 2016. The Chi square test from SPSS 16.0 software was utilized to compare and analyze the total and sample composition ratios. Results The 82 rodents collected were identified as 3 species from 3 genera and 1 family. The capture rate was 1.22%. Rattus norvegicus was predominant species and counted for 59.76%. The 20 663 mosquitoes captured were identified as 4 species from 3 genera and 1 family. Adult mosquito density was 9.92 per lamp hour and the Culex tritaeniorhynchus species was predominant species and amounted to 67.74%. The 3 876 flies trapped belonged to 7 species, 5 genera, 3 families. The fly density was 19.38(individual/cage). Lucilia sericata was predominant species and occupied 44.48%. The 4 005 cockroaches trapped were identified as 3 species in 2 genera and 1 family. Cockroach density was 2.31(individual/sheet) and Blattela germanica was predominant species and occupied 93.23%. Rodents and cockroaches were active all year round, but they were higher in summer and autumn. There was an obvious seasonal pattern of mosquitoes and fly activity, and the peak period was from June to September. Conclusion We have basically mastered the community structure and seasonal fluctuations of the rats, mosquitoes, flies and cockroaches in Guangxi. It should be strengthened on surveillance and control of vectors and vector borne diseases in Guangxi Zhuang Autonomous Region.

摘要： 目的 调查2016年广西壮族自治区（广西）两个国家级病媒生物监测点鼠、蚊、蝇、蜚蠊的种群构成和季节消长，为开展病媒生物防制工作提供科学依据。方法 鼠类监测采用夹夜法；蚊类监测采用诱蚊灯法；蝇类监测采用笼诱法；蜚蠊监测采用粘捕法。结果 2016年全年共捕获鼠类1科3属3种共82只，鼠密度为1.22%；褐家鼠为优势种，占捕鼠总数的59.76%。捕获蚊类1科3属4种共20 663只，成蚊密度为9.92只（灯/·h）；三带喙库蚊为优势种，占捕蚊总数的67.74%。捕获蝇类3科5属7种共3 876只，蝇密度为19.38只/笼；丝光绿蝇为优势种，占捕蝇总数的44.48%。捕获蜚蠊1科2属3种共4 005只，蜚蠊密度为2.31只/张；德国小蠊为优势种，占捕获总数的93.23%。鼠类、蜚蠊全年均有活动，但以夏秋季密度较高。蚊类和蝇类活动有明显的季节性，高峰期为6-9月。结论 基本掌握了广西鼠、蚊、蝇、蜚蠊的种群构成和季节消长规律。建议加强对病媒生物及其传播疾病的长期监测、预警、控制对策和措施的研究工作。
