摘要: 目的 调查上海地区不同地点、不同生境游离媒介蜱的种类及分布,为蜱媒疾病防制提供依据。方法 采用布旗法,于2021年4-7和9-11月在松江、黄浦、崇明、嘉定、宝山、静安、普陀和闵行区等13个调查点采集植被中的游离蜱;形态鉴定后扩增16S rRNA和细胞色素C氧化酶亚基Ⅰ(COⅠ)基因序列,利用获得的序列鉴定蜱种并构建系统发育树。结果 共采获游离蜱1 937只,隶属2属3种,分别为血蜱属的褐黄血蜱、长角血蜱和扇头蜱属的微小扇头蜱,分别占采获总数的92.36%、6.66%和0.98%。山坡林地采集褐黄血蜱和微小扇头蜱2种400只,占20.65%;公园/景区采集褐黄血蜱和长角血蜱2种1 341只,占69.23%;农村荒地采集褐黄血蜱1种82只,占4.23%;城市绿地采集褐黄血蜱1种114只,占5.89%。系统进化树显示,采获的同一蜱种位于同一进化分支上。结论 上海地区不同生境中游离蜱共有3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。

Abstract: Objective To investigate tick species and distribution in different locations and habitats in Shanghai, China, and to provide basic data for the prevention and control of tick-borne diseases. Methods From April to November, except August, in 2021, the drag-flag method was used to collect questing ticks in vegetation at 13 investigation sites in Songjiang, Huangpu, Chongming, Jiading, Baoshan, Jing’an, Putuo, and Minhang districts. After morphological identification, the 16S rRNA and cytochrome c oxidase subunit Ⅰ (COⅠ) gene were amplified to identify the tick species and construct a phylogenetic tree. Results A total of 1 937 questing ticks were collected, which belonged to 3 species from 2 genera, i.e., Haemaphysalis flava (92.36%), H. longicornis (6.66%), and Rhipicephalus microplus (0.98%). Specifically, 400 ticks (20.65%) belonging to H. flava and R. microplus were collected from wooded hillsides; 1 341 (69.23%) belonging to H. flava and H. longicornis were collected from parks and scenic spots; 82 (4.23%) belonging to H. flava were collected from rural wild lands; 114 (5.89%) belonging to H. flava were collected from urban green lands. The phylogenetic tree showed that the collected same tick species were in the same evolutionary branch. Conclusion There are three species of questing ticks in different habitats in Shanghai. The species and number of ticks vary across habitats. H. flava is the dominant species in each type of habitat.
