济南地区鼠形啮齿动物寄生螨类的定量研究

本文对济南地区鼠形啮齿动物寄生螨类进行定量研究:(1)以螨指数和寄生率为统计指标,对不同环境中的黑线姬鼠、大仓鼠的寄生革螨和恙螨数量分别进行比较,差异是显著的。(2)根据专一性指数判定:巴氏厉螨是亲黑线姬鼠的螨种,鼷鼠赫刺靖、仓鼠赫刺螨、三角血厉螨、单阳厉螨为亲大仓鼠的螨种。寄生螨对宿主性别的选择性不太严格。(3)利用Sorensell系数、Mountford指数和Pearson系数、比较不同鼠种间寄生螨的相似性,阐述了寄生螨与宿主及环境三者之间的密切关系。

A QUANTITATIVE STUDY OF PARASITIC MITES OF RODENTS COLLECTED FROM JINAN SHANDONG

A quantitative study of parasitic mites of rodents collected from Jinan district is conducted: (1) The Quantitative Index (number of mites/number of rodents)based on the specimens collected from different geographic environments are calculated.The differences are conspicuous. (2) A study of the Index of Specificity, shows that A. agraius is the species-specific host of L.pavlovskyi. C. triton is the species-specific host of H. musculi, H. criceti, H. triangularis, and A. singularis. The specificity of parasites to different sexes of host is not evident. (3) Analysis through measurements of Sorensen's Index, Mountford's Index and Pearson's Index shows that the parasites and their hosts are closely correlated with their geographic environments.
