Abstract: This paper reports the day and night active law of residual domestic rodents that we observed in a military camp site with the nine-well powered-spots method. In 12 days and nights within 6 months, the positive spots of Norway rat in 4 indoor sites were 3312, positive rate 7.52%, average 11.50 per hour. The positive spots of house mouse were 117, positive rate 0.27%, average 0.41 per night, rat acted from 18 o'clock to 8 o'clock next morning and mouse acted from 20:00-8:00. Both hour. In the species did not act in daytime. The active peak of rat was 2:00-4:00, and of mouse was 24:00-2:00, the action of both species of residual domestic rodents differed in quantity and frequency with season.

摘要： 本文报道在某部营区用九格粉板法观察残存家栖鼠昼夜活动数量和活动规律。结果表明,6个月12个昼夜4个场所残存褐家鼠踏格数3312个,踏格率7.52%,平均踏格数11.50%/h;小家鼠踏格数117个,踏格率0.27%,平均踏格数0.41个/h。18时至次晨8时前,褐家鼠均有活动,而18～20时未见有小家鼠活动,但20时后至次晨8时前多数有不同程度的活动。白天均未见它们活动。两种残存鼠各有一个活动高峰,即褐家鼠在2～4时前,小家鼠在24～2时前。每昼夜两种残存家柄鼠的活动数量和频次为春夏较高,冬季最低。
