目的 了解内蒙古边境口岸地区媒介蜱种的组成和分布，丰富蜱的种群数据库，为开展蜱媒疾病研究提供依据。方法 于2019年3－6月在内蒙古自治区6个盟（市）的15个旗（县）应用人工布旗法和体表检蜱法进行游离蜱和寄生蜱的采集，采集到的蜱样本进行形态学鉴定并对种群分布进行统计学分析。结果 共采获蜱样本959只，经形态学鉴定隶属于2科6属10种，其中森林革蜱采获数量最多，共566只，占比为59.02%。在呼伦贝尔市采获的样本数最多，占采获总数的50.47%。通过对采集的环境进行分析，在草地采获的蜱种类最多，其次为羊身上的寄生蜱种。结论 内蒙古边境口岸地区蜱种类丰富，需加强蜱的监测，做好蜱媒传染病的防控工作。
Objective To understand the species composition and distribution of ticks in border port areas in Inner Mongolia, to add data to the tick population database, and to provide a basis for the control of tick-borne diseases. Methods From March to June 2019, free-living and parasitic ticks were collected in 15 banners (counties) of six leagues (prefectures) in Inner Mongolia Autonomous Region with flagging cloth or from the body surface of hosts. The collected ticks were used for morphological identification and species distribution analysis. Results A total of 959 ticks were collected. A total of 10 species of 6 genera of 2 families were identified by morphological identification, of which Dermacentor silvarum was dominant (566, 59.02%), and the highest number of 484 ticks were collected in Hulun Buir city (50.47%). The highest number of ticks were collected from grasslands, followed by sheep. Conclusion The border port areas in Inner Mongolia are inhabited by various tick species. It is necessary to enhance tick surveillance to prevent tick-borne infectious diseases.
