小家鼠(Musmusculus Linnaeus)是与人伴栖的常见害鼠。近年该鼠在贵州省息烽县各种害鼠混合种群中所占比例迅速上升,由过去的25.16%增加到60%以上,上升为主要害鼠。为了给防治提供依据,我们采用夹夜法,在息烽县下阳朗乡定期采集标本,观察研究小家鼠的生态,结果报告如下。1 种群数量分布经住宅、稻田、旱地三种生境逐月调查结果,小家鼠主要分布在住宅区,占总捕获量的96.35%,稻田、旱地仅占3.65%。又据对不同生境鼠密度统计,住宅为4.17%,稻田和旱地分别为0.33%和0.11%,其结果与数量分布趋势一致,说明在息烽县小家鼠以家栖
Mus musculus (Linnaeus) is a familiar rat associated with humans. In recent years, the rat in the Xifeng County, Guizhou Province, all kinds of pest rat population increased rapidly from 25.16% in the past to 60% or more, rising as the main rat. In order to provide a basis for prevention and treatment, we use the method of nocturnal capture in Yang Xifeng County, Xifeng County regularly collect specimens observed and observed the ecology of Mus musculus, the results are reported as follows. 1 Population distribution According to monthly survey results of residential, paddy and dryland habitat, Mus musculus mainly distributed in residential areas, accounting for 96.35% of the total catch, paddy fields, dry land accounted for only 3.65%. According to the density of different habitats statistics, residential 4.17%, paddy fields and dry land were 0.33% and 0.11%, the results of the same with the number of distribution trends, indicating Xifeng County House mouse home habitat
