摘要
本文对200匹黄胸鼠臼齿的研究结果表明,一龄以上鼠占总体的68.5%(1～3龄占62%),10月龄以下鼠占31.5%;在344匹检测鼠疫菌阳性的黄胸鼠中,一龄以上鼠占85.76%,一龄以下鼠占14.24%。这一年龄分布特点,反映了黄胸鼠种群生态演替规律及其鼠疫动物流行病学意义。
The results of the molar investigation in 200 Rattus flavipectus individuals showed that in the population of Rattus flavipectus, 68.5% were more than one year old (62% were 1-3 year old), 31.5% were less than to month old. In 344 infected individuals, which confirmed by bacterial isolation, 85.76% were more tha onen year old and 14.24% were less than one year old. Tbis character of age distribution reflected the patterns of ecological succession and plague epizootics in the Rattus flavipectus population.
