摘　　要：目的测定东方田鼠对杀鼠灵的敏感性基数,以便进行更有效的鼠害防治。方法捕捉试鼠,配制毒饵进行不同天数的攻毒试验,观察分析食毒期与对应死亡率的关系,并比较性别间的差异。结果雌雄东方田鼠对杀鼠灵的敏感性差异无统计学意义,合并后计算LFP50、LFP98和LFP99的估计值(95%置信限)分别为2.51(2.24-2.81)d、25.08(21.76-28.91)d和29.37(25.25-34.17)d。结论东方田鼠对杀鼠灵的敏感性本底及抗性检验标准为0.002%浓度杀鼠灵食毒29d或30d存活。Objective To learn about the sensitivity of the Yangtze vole （Microtus fortis ） to warfarin, and control efficiently its damage. Methods The voles were captured on the lake bank or the beach nearby and divided into 5 groups which was provided wafarin baits for 1 d, 2 d, 4 d, 6 d and 8 d respectively. The relation of the feeding period and the mortality was observed and analyzed, and the sexual differentiation was compared. Results There is no significant difference between male and female voles, and the evaluated values of LFP50, LFP98, LFP99 （with 95% confidence interval） were 2.51 （2.24- 2.81）d, 25.08（21.76- 28.91）d and 29.37（25.25 34.17）d respectively. Conclusion It was suggested the vole had resistance to warfarin if they still survived after feeding on 0. 002 % warfarin for 29 d or 30 d.
