Abstract: The paper introduces the investigations of Rattus norvegicus on susceptibility and resistance to 0.005% Warfarin bait in Jinan Military Area where anticoagulant rodenticide have been used for many years. It indicated that resistance incidence of R.norvegicus was 2.04% in Jinan city, and 4.17% in Xuchang city while R.norvegius were still susceptible to anticoagulant rodenticides in Weifang city and Huixian city. In the laboratory, all of the killing rates with “un-selective ingesting”were all 100.00% to Indian corn bait containing 0.005% Bromadiolone, 0.025% Racumin and 0.025% Diphacine-Na, killing rate with “selective ingesting”were 92.86% in Bromadiolone bait, 61.54% in Racumin, and 38.46% Diphacine-Na. Ingesting index was 0.70 in Bromadiolone bait, 0.45 in Racumin and 0.22 in Diphacine-Na. In the field trial, the palatability of Bromadiolone and Racumin rice baits to R. norvegicus were better than Diphacine-Na and the control deratization rates were 85.11%, 87.33% and 81.55% respectively.
摘要: 目的:测定褐家鼠的抗药性,观察抗凝血剂灭鼠效果。方法:抗药性调查,采用毒饵消耗法;灭效观察,采用3d饱和投饵法。结果:济南市和许昌市部队驻地褐家鼠对杀鼠灵的抗药性发生率分别为2.04%和4.17%;潍坊市和辉县市虽未发现抗性鼠,但部分敏感褐家鼠个体对杀鼠灵的药物耐受性已经明显增强。溴敌隆、杀鼠迷和敌鼠钠盐3种抗凝血灭鼠剂对褐家鼠的实验室毒杀效果,无选择摄食试验毒杀率均为100%;而有选择摄食试验毒杀率分别为92.86%,61.54%和38.46%,摄食系数依次为0.70、0.45和0.22;现场灭鼠试验,溴敌隆和杀鼠迷毒饵盗食率明显高于敌鼠钠盐,灭鼠率则分别为85.11%、87.33%和81.55%,三者间差异无显著性。结论:今后应加强抗药性监测,合理指导灭鼠用药,以减少褐家鼠抗药性的进一步发生。
