Abstract: Abstract:Objective Investigation and analysis for the classification，characteristics and possible pathogenic to animals of the parasite infection in tupaia belangeri chinensis，to provided the scientific basis for protecting tree shrew population and the quality control of breeding tree shrew． Method Two hundred wild tree shrews were random selection，then we took living floating and depilating to detect the epizoic parasites，at the same time took faeces precipitation and faeces floating method to detect endoparasite，at last，diagnosed species of parasites under the platoscope and microscope． Ｒesult The epizoic parasites in wild tree shrew were respectively louse(20. 5% )， flea(5. 5% )，sarcoptid mite (3. 0% )，Ixodes granlalus(1. 0% )，Niptus bololeucus Faldermann (1% )，Thorictodes brevipennis(1% )，W． acranulat(1% )，Anobiidae Fleming(0. 5% ) ;The endoparasite were respectively wireworm (14% )，Wireworm egg ( 33% )，tapeworm ( 9% )，tapeworm egg ( 20% )，amoeba ( 2% ) ． Conclusion Parasite species with infection tupaia belangeri chinensis were a great variety，should be recognised as serious，we could not be underestimated its impact on tree shrew population．

摘要： 摘要:目的调查分析野生滇西亚种树鼩体内外寄生虫感染种类及特征，分析其可能对动物的致病性，为人工饲养 树鼩的质量控制和保护树鼩群体提供科学依据。方法随机选取200 只野生滇西亚种树鼩，分别用活体漂浮法和 直接拔毛法制片，置于体视镜和显微镜下鉴定体外寄生虫种类;体内寄生虫分别采用粪便漂浮法和粪便沉淀法进 行检测，并在显微镜下鉴定。结果野生滇西亚种树鼩体外寄生虫感染率分别为虱20. 5% 、蚤5. 5% 、螨3. 0% 、颗 粒硬蜱1. 0% 、黄蛛甲1% 、圆胸皮蠹1% 、水蛭1% 、蛛甲0. 5% ;体内寄生虫感染率分别为线虫14% 、线虫卵33% 、 绦虫9% 、绦虫卵20% 、变形虫2% 。结论野生滇西亚种树鼩体内外寄生虫的自然感染种类繁多，对树鼩群体的 影响不可低估，应该引起重视。
