摘要
1980～1981年在山东省6地市17个村庄室内经7996夹夜调查,1981、1983年在宿家村及其邻村室内经1524夹夜调查,均未捕到大仓鼠。宿家村在1983年12月用敌鼠钠毒饵进行了彻底灭鼠,从1984年4月至1985年2月经4924夹夜调查,总捕获率为9.65%,大仓鼠的捕获率为2.03%,占总数的21.05%。其间共捕大仓鼠100只,黑线姬鼠34只。而5月及9、10月三个月内捕到大仓鼠69只,但仅捕到黑线姬鼠1只。作者认为,①村内彻底灭鼠后大仓鼠存在入侵现象,其原因可能是室内家鼠的栖息地成了空白,易被其他鼠类占领;另外,可能也与野外大仓鼠密度较高有关。②大仓鼠的入侵在5月及9、10月形成了两个高峰;大仓鼠与黑线姬鼠向村内入侵时可能存在对抗现象。
An investigation on house rodents was carried out in 17 villages of 6 municipalities and prefectures in Shandong province. 1980～1981. In the investigation of 7996 trap-nights, the total capture rate was 11. 45%, C. triton was no trapped. Investigation on house rodents was carried out in Xujia village in Jinan suburb, in August 1981 by 588 trap-nights, the total capture rate was 7.99%. 1983, 612 trap-nights in a bout village of Xujia and in September of 1984, 316 trapnights was studied; no C. triton was trapped either. Since Diphacine-Na treated baits were used repeatedly in December 1983 to kill house rodents at Xujia village, investigation of 897 trap-nights in January 1984 revealed a capture rate of 0.45% From April 1984 to February 1985 C. triton was trapped in every mouth. From January 1984 to February 1985, 4924 trap-nights showed a total trapture rate of 9.65%; the capture rate of C. triton was 2.03%, accounting for 21.05% of the total, From April 1984 to February 1985, 100 C. triton and 34 A. aglarius were trapped and 69 C. triton and 1 A. aglarius were trapped in three mouths of May, September and October. The result indicated that there appeared a succession of house rodent commynity and C. triton invaded the village after a thorough elimination of house rodents in rural areas. Another explanation for the persistent and severe invasion of C. triton may be its relatively high density in the fields. There are two peak of invasion(One in May, another in September and October). During the invasion, there might be a confrontation between A. agrarius and C. triton.
