高黎贡山及担当力卡山9种革螨空间分布型研究

Research on Spatial Pattern of Gamasid Mitesfrom the Mountains of Gaoligong and Dandanglika

目的：研究山地革螨在小型哺乳动物宿主间的空间分布格局。方法：在常规分类鉴定的基础上，以宿主个体为样方单位，统计不同种类革螨在各样方的分布数量，然后用聚块指数测定各种革螨的空间分布型。结果：采自云南西部高黎贡山及担当力卡山的贵州厉螨、兴义厉螨、毒厉螨、纳氏厉螨、福建厉螨、土尔克厉螨、金氏厉螨、田鼠上厉螨及贡山血革螨９种革螨在其主要寄生宿主体表均表现为聚集型分布。结论：所研究的９种革螨在其寄生生活中具有群聚效应。

Objective:To study the spatial pattern of the gamasid mites,on the body surface of small mammal hosts. Methods:The studied gamasid mites were conventionally identified and classified and the small mammal hosts ectoparasitized by the mites were regarded as sampling units.After adding up the individual distribution of different species of the mites on each host sampling unit,patchness index was used to measure the spatial patterns of various species of gamasid mites. Results:9 main species of gamasid mites collected from the Mountains were chosen as the target mites in this paper.All the involved mites on their correspondent small mammal hosts showed an aggregated distribution pattern.Conclusion:9 species of gamasid mites involved have an aggragated living habit or tendency when they parasitize their corresponding small mammal hosts as ectoparasites.
