摘　　要：198 9～ 1998年对内蒙古阿巴嘎旗那仁宝力格苏木布氏田鼠Microtusbrandti体蚤和巢蚤的数量进行了调查和分析 ,所得体蚤包括 3科 7属 9种 ,其中优势种有 :原双蚤田野亚种Amphipsyllapri marismitis占 4 1 84 % ,近代新蚤东方亚种Neopsyllapleskeiorientalis占 4 1 18% ,光亮额蚤Frontopsyllaluculenta占 13 18%。所得巢蚤包括 2科 6属 9种 ,其中优势种近代新蚤占 74 94 % ;光亮额蚤占10 0 4 % ,原双蚤占 8 2 0 % ,宽圆纤蚤Rhadinopsyllarothschildi占 6 4 4 % ,是常见种。田鼠体的原双蚤、近代新蚤、光亮额蚤和体蚤指数间呈正相关 (P <0 0 5)。田鼠巢的近代新蚤、光亮额蚤、宽圆纤蚤和巢蚤指数间正相关显著 (P <0 0 1)。春季巢蚤指数∶春季体蚤指数≈ 5∶1,秋季巢蚤指数∶秋季体蚤指数≈ 75∶1。近代新蚤既是体型蚤又是巢型蚤 ,为田鼠的优势蚤种 ;原双蚤数量占体蚤的4 1 84 % ,是体型蚤 ;An investigation on body and burrow fleas of the Brandt's vole, Microtus brandti, in Narenbaolige Sumu, Abaga Banner, Inner Mongolia, during 1989～1998 was summarized. Nine flea species in 7 genera in 3 families were found on the vole body with Amphipsylla primaris mitis as the dominant species(41 8%),followed by Neopsylla pleskei orientalis (41 2%) and Frontopsylla luculenta (13 2%). Nine flea species in 6 genera of two families were detected in the vole burrow nest with N.p.orientalis as the dominant species (74 9%). F.luculenta (10 0%), A.p. mitis (8 2%) and Rhadinopsylla rothschildi (6 4%) were commonly occurring. There was a positive correlation between the index of A. p.mitis, N. p. orientalis and F. luculenta and that of all the fleas on the vole body( P <0 05),respectively. The correlation coefficient between index of N. p.orientalis, F. luculenta and R.rothschildi and that of the total fleas in the vole burrow nest was significant( P <0 01),respectively. The proportion of burrow flea index to that of body flea was about 5∶1 in spring while it approached 75∶1 in autumn. N. p.orientalis was the dominant species either in the vole body fleas or in the nest ones. Of the vole body fleas 41 8% was A. p. mitis, which belonged to the body type flea. F.luculenta was common flea species on the vole body and in its burrow.
