黑线姬鼠(Apodemus agrarius Pallas)是我县害鼠的优势种,一般占害鼠总捕获数的80%以上。为探明黑线姬鼠种群发生规律和环境对发生动态的影响,进一步提高灭鼠的总体效益,我站于1985～1989年连续5年开展了黑线姬鼠种群发生规律研究,取得以下结果。试验研究方法1.鼠情监测:在城东乡镇东村设置系统鼠情监测点,在每月中旬,用标准中号鼠夹捕捉害鼠。具体方法:100只鼠夹连续布放3夜,晚放晨收,用新鲜花生米作诱饵.沿田埂每隔5～7m 设一夹,3夜共放300夹次,对捕到的害鼠进行种类鉴定,计算各鼠种的比例,对 Apodemus agrarius Pallas is the predominant species of pest in our county, accounting for more than 80% of the total number of pests. In order to find out the rule of Occurrence of Apodemus agrarius and its influence on environment, and to further improve the overall effectiveness of rodent control, I studied the regularity of population occurrence of Apodemus agrarius in 1985 ~ 1989 and obtained the following results . Experimental research methods 1. Rodent surveillance: Set up a systematic rodent monitoring point in the east village of Chengdong Township. In the middle of each month, standard rodents are used to capture the rodents. Specific methods: 100 rats were placed consecutively for 3 nights, late morning morning harvest, with fresh peanuts as a bait along the field 田 every 5 ~ 7m set a folder, put a total of 300 times in three nights, caught the rat Identification of species, calculate the proportion of each rat species, right
