【摘要】 黄兔尾鼠较广泛分布于内蒙古北部荒漠草原，主要栖息于河谷低地、湖盆低地及台地间的凹地内，常与长爪沙鼠和子午沙鼠混合分布，栖居关系密切，共同寄生着主要蚤类。在鼠疫动物病频发的河谷低地生境内，黄兔尾鼠积极参加长爪沙鼠鼠疫流行；实验室研究证明，它对鼠疫菌具有感受性，其敏感性个体差异较大。种群的抗性较高和菌血症时间较长。在黄兔尾鼠集中分布地区，他对鼠疫的传播和保存起着重要作用，是多宿主疫源地成员之一。更多还原

【Abstract】 Lagurus luteus distribute widely in the Desert Prairie of Northern Inner Mongolia,Especially in the low valley,low lakeside and the low tab1eband of the prairie.It live closely and has main vector fleas together with Meriones unguiculatus and Meriones meridianus.It actively joins the prevalent processes of M.unguiculatus plague in the habitats of low valley where the epizootiology of plague frequently.Experimenta1 Studies show that it is susceptib1e to plague bacillus,thereare greater differences in the susceptbi1itiesamong the individuals.The resistances and bacteriemia periods of its population are greater and longer respectivelly.It plays an important role in the processes of p1ague transmission and conservation in the areas where its population is concentrated and it is the host member of polyhost foci.更多还原
