【摘要】 目的了解青海省三江源地区的蚤类种群区系分布。方法结合鼠疫疫源地的调查和监测工作,对捕获的小型兽类进行体外捡蚤,采集蚤类标本并分类鉴定。结果青海省三江源地区共发现蚤类104种(含亚种),隶属于6科33属,以角叶蚤科、细蚤科、栉眼蚤科种类居多,分别占33.65%(35/104)、27.88%(29/104)和24.04%(25/104)。羌塘高原亚区发现蚤类5科16属34种,青海藏南亚区蚤类6科33属100种,其中三江源地区特有蚤类28种。结论进一步开展蚤类生物学调查,加强媒介生物控制研究,为鼠疫防治提供理伦依据。更多还原

【Abstract】 Objective To determine the flea fauna and distribution in Three Rivers’ Headwaters region of Qinghai province. Methods Based on the results of the investigation and surveillance on plague foci,fleas were collected in vitro from the captured small mammals in the regions,and taxonomic identification was conducted. Results A total of 104 species of fleas had been found in Three Rivers’ Headwaters region in Qinghai (including sub-species),belonging to 33 genera,6 families,the dominant species being Ceratophyllidae,Leptopsyllidae and Ctenophthalmidae,accounting for 33.65% (35/104),27.88% (29/104) and 24.04% (25/104),respectively. Thirty four species,16 genera and 33 families in the Qiangtang Plateau sub-region,100 species,16 genera and 6 families in South Tibet sub-region were also found,including 28 unique species in Three Rivers’ Headwaters region. Conclusion Further biological investigation on fleas should be strengthened along with vector control research in order to provide data for the prevention and control of plague.更多还原
