Abstract: Objective To investigate the species, number, geographical distribution, host, and seasonal fluctuation of ticks in Zhengzhou, China, and to provide a basis for tick prevention and control. Methods Free-living ticks were collected with the tick drag-flag method in Zhengzhou from January to December in 2019. Host infection by ticks was investigated by capturing ticks from animals' body surface. Data were collected, calculated, and analyzed using Excel 2019 software. Results All the ticks collected from populated and unpopulated rural areas, mountains, and scenic spots in Dengfeng, Xinmi, Gongyi, Xingyang, and Xinzheng cities as well as Zhongmou county were identified as Haemaphysalis longicornis. The average density of free-living ticks was 6.97 ticks/100 m, the average infection rate was 41.18%, and the average number of ticks per host was 2.03. H. longicornis first appeared in April, had the highest density in July, and disappeared in November. Conclusion H. longicornis is mainly distributed in the unpopulated rural areas and scenic spots of Zhengzhou, and tends to spread to the urban areas. The population activity peaks in summer and autumn.

摘要: 目的 掌握郑州市蜱的种类、数量、地理分布、寄生宿主及季节消长情况,为蜱类防控提供依据。方法 2019年1-12月在全市范围内采用布旗法调查野外游离蜱,采用动物体表查捉法调查蜱对不同宿主侵害情况。用Excel 2019软件对收集数据进行汇总、计算、分析。结果 在登封、新密、巩义、荥阳、新郑市及中牟县农村居民区、农村外环境、山区和景区捕获到蜱,均为长角血蜱,野外游离蜱平均密度为6.97只/100 m,寄生蜱对寄生宿主侵害阳性率为41.18%,宿主平均寄生数量为2.03只;长角血蜱自4月开始出现,7月达密度高峰,11月蛰伏消失。结论 长角血蜱在郑州市主要分布于农村外环境和景区,有向城区蔓延倾向,种群活动高峰期集中在夏秋季。
