目的调查高原鼢鼠寄生蚤种类,在种群水平分析蚤的组成和空间分布,为进一步明确高原鼢鼠寄生蚤的区系特征提供科学依据。方法用鼢鼠死捕弓箭诱捕鼢鼠,梳检每只鼢鼠的所有寄生蚤,在实验室进行种类鉴定和统计分析。结果在18个样点中共捕获高原鼢鼠282只,其中染蚤鼠203只,总染蚤率为71.99%;共检获体表寄生蚤835匹,总体蚤指数为2.96匹/只;聚类分析显示,所有样点聚成3大支系,其中A支系副规新蚤占优势,B支系鞍新蚤占优势,C支系感染的总蚤数最少。结论副规新蚤在青海湖周边占绝对优势,青海省东南部地区是鞍新蚤特有的分布区,黄河并未对寄生蚤的区系产生影响。
Objective To investigate the species of parasitic fleas in plateau zokor and to analyze the composition and spatial distribution of fleas at population level to provide a scientific basis for further clarifying the flora characteristics of parasitic fleas on plateau zokor. Methods The zokor were captured by the dead catcher, and all the parasitic fleas of each zokor were examined by combing. Species identification and statistical analysis were performed in the laboratory. Results A total of 282 plateau zebra rats were captured at a total of 18 sites, of which 203 were infected with fleas. The total flea infection rate was 71.99%. 835 parasitic fleas on the surface were collected and the total flea index was 2.96 / All the samples were clustered into three major genera, of which A was the predominant species of the new strain, B was the predominant species, and C was the least infected. Conclusion The parasitoid New fleas occupy the absolute superiority around Qinghai Lake. The southeastern Qinghai Province is a unique distribution area of the saddle flea, and the Yellow River does not affect the flora of the parasitoid fleas.
