摘要: 1982~1996年对内蒙古自治区鄂托克前旗长爪沙鼠Meriones unguiculatus体蚤和巢蚤的数量进行了调查和分析,得到如下结果。获体蚤15种,同型客蚤指名亚种Xenopsylla conformis conformls (50.8%) 和秃病蚤蒙冀亚种Nosopsyllus laveiceps kuzenkovi (40.6%)为优势种。获巢蚤15种,秃病蚤蒙冀亚种(74.3%)为优势种;盔状新蚤Neopsylla galea (11.9%)和叶状切唇蚤突高亚种Coptopsyllus lamelliferardua (8.1%)为常见种。年巢蚤指数的均值是年体蚤指数的6.92倍。体蚤指数与巢蚤指数不相关(P>0,05),体染蚤率与巢染蚤率不相关(P>0.05)。不同年份 的体蚤和巢蚤多样性比较稳定。连续两年春季或秋季秃病蚤巢蚤指数大于10只后,可能流行动物鼠疫。

Abstract: An investigation on the body fleas and burrow nest fleas of Meriones unguiculatus in Etuokeqian Banner of Yikezhao League, Inner Mongolia Autonomous Region during 1982-1996 was summarized asfollows: There were fifteen flea species on the gerbil's body with Xenopsylla conformis conformis (50.8%) as the dominant one and Nosopsyllus laveiceps kuzenkovi (40.6%) coming second. There were fifteen flea species in the gerbil's burrow nest with N. l. kuzenkovi (74.3 % ) as the dominant species and the common species being Neopsylla galea ( 11.9 % ) and Coptopsyllus lamellifer ardua (8.1% ). Theindex of the yearly burrow nest flea averaged 6.92 times that of the body flea. No correlation was found between the fleas of body and burrow nest (P>0.05), and between their infection rates (P>0.05). Both the diversity and evenness of body and burrow nest fleas were stable relatively in different years. As the burrow nest flea index of N. I. Kuzenkovi in spring or autumn reached above ten in two successive years, the animal plague might occur.
