摘    要:探讨臭与鼠疫动物病的关系。方法:汇集1982—1994年云南西部瑞丽市、陇川县、盈江县和保山市的调查资料,较全面地对臭的相对数量变动及与鼠疫的关系进行比较研究。结果:臭在全境的鼠形动物中占26.07%。在不同县市室内、室外的组成比明显不同。最适分布区是温、湿度较高坝区村庄周围的农田、菜园树灌篱笆带。种群相对数量的季节消长,室内:瑞丽呈马鞍型,陇川和盈江都呈单峰型,保山呈双峰型;室外:4县市均呈单峰型。种群雌体怀孕率在瑞丽是双峰型。臭的鼠疫菌检出率比其它几种家鼠的低。结论:臭是否为云南鼠疫的贮存宿主,有待进一步证实。

Abstract:The seasonal variation and the plague relationship of Musk shrew popuIation density was overall studied with the investigated data from Ruili twon, Ying jiang, Long chuan counties and Bao shan twon from 1982 to 1994. The thsk shrew was 26. 07% of the rat-like maxnmals community in the panorama. Its constituent ratio were evidently different in the dissimilar counties/twons and between indoor and outdoor habitats, Its optimum distribution area was the vegetable garden-hedgerow of high temperature -humidity in villages. Indoor, the seasonal variation of Musk shrew population showed the shape of a saddIe in Ruili twon, one peak type in the Long chuan and Ying jiang, two peaks type in Bao shan twon; Outdoor, they all presented one peak in four counties/twons. The pregnancy rates indoor and outdoor were two peaks type in Ruili twon. It was low the quarantine rate of the Yersinia pstis compared with that of rat species.
Keywords:Musk shrew Population dynamics Seasonal variation Plague
