臭鼩鼱昼夜活动规律的观察

Investigation on the law of Day and Night Action of Suncus murinus

本文于1991年3～12月在驻广州市郊某部营区,用九格粉板法观察了臭鼩鼱昼夜活动规律。结果表明,臭鼩鼱平均每小时踏格数7.13个。18～3时踏格数占昼夜踏格数的99.56%;其中上半夜占昼夜踏格数的37.72%,下半夜占61.84%,夜间有两个活动高峰,上半夜在办公楼和伙房人为干扰较少时,其活动高峰为20～22时,在宿舍人为干扰较大条件下,活动高峰为22～24时;下半夜其在3个场所的活动高峰为2～4时。从不同月份活动高峰看,3、12月上半夜为20～22时,6月份为22～24时;3、6、9月下半夜均在2～1时,12月在4～3时。不同场所昼夜活动数量是,办公楼>伙房>鸡舍>宿舍;不同时间活动数量,9月>6月>3月>12月。其昼夜活动受褐家鼠影响较大。

The law of day and night action of Suncus murinus was investig ated in some barracks on the outskirt of Guang zhou with nine—well powered—spots method from March to December in 1991. It was demon strated that 7.13 spots were stepped on every hour. From 6 p, m to 8 a, m the positive number accounted for 99.56% of all the positive spots, in which 61.84% before midnight and the rest after that. there were two peaks of night action. One was from 20 to 22 o'clock with little human interference in office and kitchen whilst 22 to 24 o'clock with a rather little move in dormitory. Another peak was from 2 to 4 o'clock in all three places. As far as the peaks in different month were concerned. The first peak in March and December was form 2o to 22 o'clock, June 22 to 24. The second peak in March, June and September was from 2 to 4 o'clock, December 4 to 6. In all the places and different time mentioned above, the freuency of Suncus muricus was as follows respectively: office>kitchen>chicken farm>dormitory; Sep>Jun>Mar>Dec. The situation of day and night action of Suncus murinus was rather infuerced by Rattus no(?)vegicus.
