蜱媒疾病风险评估中标本采集方法的探讨

Discussion of methods for specimen collection in the tick-borne risk evaluation

目的探讨自然风景区蜱媒传染病风险评估中蜱虫及宿主的采集方法。方法不同月份、不同生境进行定点游离蜱和宿主寄生蜱虫的采集,比较不同布旗、不同捕鼠路线对蜱虫及其宿主采集效率。结果镜泊湖区针阔混交林和草地的游离蜱虫5月份采集数量(99只)远远高于6、7月份(7只和1只);针织棉质布旗优于纤维麻面和棉质布旗捕获率高出7倍;6、7月份无法采集到寄生蜱;野栖鼠类及体表寄生虫采集以接近水源线路更好。结论镜泊湖景区存在蜱媒风险,蜱虫及其宿主标本的采集应注重蜱虫的季节消长、工具和方法的革新。

Objective To discuss the methods for specimen collection in the tick-borne risk evaluation in natural scenic area.Methods Free and parasitic ticks were collected in Lake Jingpo at different month and habitats.Comparing the acquisition efficiency of different cloth flag,different trap circuit to tick and the host.Results 99 ticks collected in May was much higher than that of June and July;Tick-acquisition efficiency of towels cotton cloth flag was 7 times higher than that of the traditional cloth flag;Ticks couldn't be collected after May in Lake Jingpo;High efficiency was found in rodent and parasite collection to lakeside line.Conclusion Lake Jingpo scenic area in tick-borne risk,the tick and host specimen collection should be paid attention to the seasonal variation of the tick,tools and methods of innovation.
