贵州省思南县不同生境区域鼠形动物体表革螨群落对比研究

1988年对贵州省思南县不同生境区域啮齿目及食虫目动物体表革螨群落的调查结果表明:室内生境革螨种类少、多样性低、优势种突出,以毒厉螨及柏氏禽刺螨为优势种;野外生境革螨种类丰富、多样性高、优势种不突出。其中海拔较高的山区和丘陵地带野外生境革螭群落为同一类型,以毒厉螨及土尔克历螨为优势种,低海拔平坝地带为另一类型,以鼠颚毛厉螨为优势种。

COMPARISON ON GAMASID MITE COMMUNITIES ON RAT-LIKE ANIMALS IN DIFFERENT HABITATS AND REGIONS IN SINAN COUNTY, GUIZHOU PROVINCE

The gamasid mite communities on Rodentia and Insectivora in different habitats and regions in Sinan County, Guizhou Province had been investigated. The result showed that there were fewer species of gamasid mites in indoor habitats and its diversity was low, but the position of the dominant species, Laelaps echidninus and Ornithonyssus bacoti, was prominent. Outdoor habitats were rich in gamasid species, its diversity was higher and the position of the dominants was not prominent. Ail the gamasid mite communities of the outdoor habitats in mountainous and hilly regions were of the same types, and the dominant species were Laelaps echid ninus and Laelaps turkestanicus . The gamasid mite community of the outdoor habitat in flat-land region where the altitude is low was another type, and its dominant species was Tricho-Iaclaps myonysngnathus.
