温州市宿主动物体表寄生蜱初步调查分析

Investigation and analysis of ticks on body surfaces of host animals in Wenzhou city,Zhejiang province,China

目的了解浙江省温州市蜱类种群和分布情况,为相关蜱传疾病防控提供科学依据。方法 2011年对温州市2个山区县(泰顺、永嘉)的黄牛、猎狗、野猪以及6个鼠疫监测点(文成、乐清、瑞安、永嘉、鹿城和龙湾)捕获的鼠形动物体表寄生蜱进行调查。结果从各类宿主动物体表捕获蜱1科4属7种353只,长角血蜱为优势种,黄牛、猎狗、野猪和鼠形动物的香浓-威纳指数分别为0.8905、0.5879、0.8760和0,黄牛和野猪体表寄生蜱群落的物种丰富多样。结论温州市存在媒介蜱类,应加强蜱类种群季节消长及莱姆病、埃立克体病、发热伴血小板减少综合征等蜱传疾病监测。

Objective To investigate the distribution of the ticks on the body surfaces of host animals in Wenzhou city,Zhejiang province,China,and to provide a basis for the prevention and control of tick-borne diseases.Methods Ticks were collected from the body surfaces of cattle,hounds,wild boars,and murine-like animals.Results A total of 353 ticks（7 species,4 genera,1 family） were collected from the body surfaces of cattle,bounds,wild boars,and murine-like animals,with Haemaphysalis longicornis as the dominant species.The Shannon-Wiener indexes of cattle,hounds,wild boars,and murine-like animals were 0.8905,0.5879,0.8760,and 0,respectively.There were abundant and diverse species of ticks on the body surfaces of cattle and wild boars.Conclusion There are vector ticks in Wenzhou city,Zhejiang province,China,and measures should be taken to strengthen the surveillance on the seasonal fluctuation of tick population density and tick-borne diseases such as Lyme disease,Ehrlichiosis,and fever with thrombocytopenia.
