黑线姬鼠(Apodemus agraius)是贵州省农田主要害鼠。根据余庆1986—1992年所捕获的3742只害鼠分类统计,黑线姬鼠占94.76%。为搞好防治,本文主要对黑线姬鼠种群繁殖特征的季节变化进行了调查研究,结果整理如下。1 研究方法调查工具采用北京产7×17厘米木板夹,田间直接或曲线排列,夹行距5×50米,花生仁作诱铒,每月中旬在稻田、旱地各置夹200夹夜以上,统计捕鼠数,计算捕获率,分别解剖观察黑线姬鼠的各项繁殖特征,分析
Apodemus agraius is the main pest in farmland in Guizhou Province. According to the statistics of 3742 infected rats collected by Yu Qing from 1986 to 1992, Apodemus agrarius accounted for 94.76%. In order to do a good job of prevention and treatment, this paper mainly studies the seasonal variation of reproductive characteristics of Apodemus agrarius population. The results are summarized as follows. 1 research methods survey tools using Beijing produced 7 × 17 cm wood clip, the field directly or curvilinear arrangement, clip spacing 5 × 50 meters, peanut as bait, middle of every month in paddy fields, dry land set folder 200 clips over night, statistics Catch the number of mice, calculate the capture rate, respectively, dissection observation of Apodemus brevis mucosal reproduction characteristics, analysis
