Abstract

Abstract: Objective To investigate the features of vector ticks in the vegetation of different habitats and locations in Suzhou, China, and to provide a basis for the control of tick-borne diseases. Methods From April to November, 2018, the drag-flag method was used to collect questing ticks from the vegetation at 7 investigation sites of Zhangjiagang, Changshu, Kunshan, and Taicang cities and Huqiu, Wujiang, and Wuzhong districts, once per month. Results A total of 1 759 questing ticks were collected and were identified as one genus and four species by taxonomic identification, i.e., Haemaphysalis flava (99.09%), H. longicornis (0.68%), H. campanulata (0.17%), and H. phasiana (0.06%). A total of 1 501 H. flava ticks were collected in parks/scenic areas and accounted for 85.33%; 175 ticks belonging to 4 species were collected in hillside forests and accounted for 9.95%; 63 H. flava ticks were collected in urban green land and accounted for 3.58%; 20 ticks belonging to H. flava, H. longicornis, and H. campanulata were collected in rural wild grasslands and accounted for 1.14%. A total of 1 399 questing ticks were collected in Zhangjiagang and accounted for 79.53% of all ticks, and 102 (5.80%), 87 (4.94%), 23 (1.31%), 67 (3.81%), 80 (4.55%), and 1 (0.06%) ticks were collected in Taicang, Kunshan, Changshu, Wujiang, Huqiu, and Wuzhong, respectively. Conclusion There are 4 species of questing ticks in the habitats with different vegetation types in Suzhou, and the species and numbers of ticks vary across habitats. Haemaphysalis flava is the dominant species in each type of habitat.

摘要： 目的调查苏州地区不同地点、不同植被中媒介蜱的基本特征，为蜱媒疾病防制提供依据。方法采用布旗法于2018年4－11月在张家港、常熟、昆山和太仓市，虎丘、吴江和吴中区共7个调查点采集植被中的游离蜱，每月采集1次。结果共采集游离蜱1 759只，经分类鉴定为1属4种，分别是褐黄血蜱、长角血蜱、铃头血蜱和雉鸡血蜱，分别占采集总数的99.09%、0.68%、0.17%和0.06%。公园/景区采集到褐黄血蜱1种1 501只，占85.33%；山坡林地采集蜱4种175只，占9.95%；城市绿地采集褐黄血蜱1种63只，占3.58%；农村荒地采集褐黄血蜱、长角血蜱和铃头血蜱3种20只，占1.14%。张家港市共采集游离蜱1 399只，占采集总数的79.53%；太仓、昆山和常熟市，吴江、虎丘和吴中区采集蜱数量分别为102（5.80%）、87（4.94%）、23（1.31%）、67（3.81%）、80（4.55%）和1（0.06%）只。结论苏州地区不同植被类型中游离蜱共有4种，不同生境中蜱的种类和数量分布不同，褐黄血蜱为各类生境中的优势种。
