摘要: 华中地区农村小家鼠(Mus musculus)的个体较小,主要栖息于农舍,终年繁殖,繁殖高峰期为7月和8月,1-3月为繁殖低谷期;种群数量高峰在9月,低各期在7-8月,冬季的种群数量水平较高,呈后峰型。在较高的密度条件下,雌鼠的怀孕率降低,性成熟延缓。

Abstract: The biological characteristies and the populatlon dynamics of the house mouse (Mus musculus) in centre-China were investigated from October, 1986 to 1990.The body size of this mouse was a small.It mean body weight of male was only 13.84±2.7g and that of female was 16.27±3.6g.The favorite habitats of the house mouse was farmer's house.The capture rate by snaptraps lm farmer's house and fields was 5.2% and 0.12%respectively.
The house mouse breed all year round and it main breeding season wasin summer(July- August)The population peak was in autumn(September)and had a high population density in winter.The pregnant rate was low when the population density was high.
