从洞庭湖防洪大堤护坡和湖滩捕捉试鼠,在实验室做无选择性摄食试验.将试鼠雌雄分开,随机分组,配制0.000 2%溴敌隆毒饵进行不同时间的攻毒试验.用SPSS进行几率单位加权回归法(Bliss法)的计算.探讨不同食毒期与对应死亡率之间的关系.结果表明,东方田鼠性别之间对溴敌隆的敏感性差异无统计学意义,故将雌雄数据合并计算,得毒力回归方程y=0.07+2.65x,LFP_(50)、LFP_(98)、LFP_(99)及其95%置信限分别是0.94(0.43～1.33)、5.63(3.51～20.83)d和7.14(4.15～33.52)d.按WHO修订以致死99%敏感靶标鼠种的食毒期(LFP_(99))取整天数作为抗药性检验标准,洞庭湖区东方田鼠对0.000 2%的溴敌隆毒饵食毒期超过8 d存活为产生抗药性.

The voles were captured on the lake banks or the nearby beaches.The males and females were firstly separated and then divided into groups at random.No-choice tests were carried out using 0.000 2%bromadiolone bait at five different feeding days.The relationships between mortality and different feeding days were analyzed by SPSS with Bliss.There is no significant differences between male and female voles,and the LFP line was y=0.07+2.65x.On tombination of the sex data,LFP_(50),LFP_(98) and LFP_(99)(with 95%confideace interval)were 0.94 (0.43-1.33),5.63(3.51-20.83)and 7.14(4.15-33.52)days,respectively.The revised rodent resistance criterion of WHO was integer of LFP_(99).According to it,the vole Was still alive after fed on 0.0002%poison baits for 8 days in Dongting Lake region,and then it could be considered to have resistance.
