摘要: 目的 双氯敌鼠铵为我国新研制并具有自主知识产权的新抗凝血灭鼠剂,观察该药在特殊环境(冷库)防治褐家鼠的杀灭效果。方法 在0.005%双氯敌鼠铵小麦(占95%)及玉米(占5%)混合毒饵中加入0.5%食盐作为引诱剂,用一次投放法灭鼠,用鼠迹法做药效考核;从灭鼠后第2个月开始调查褐家鼠种群密度和药效,每月1次,连续6次。结果 投饵前鼠密度为55.47%,投饵后27及40d时鼠密度分别降至0.78%和0,灭效高达98.59%和100%。灭鼠后第2~7个月鼠密度均为0,灭效均高达100%。结论 双氯敌鼠铵对褐家鼠适口性好,在特殊环境中一次投饵的药效较为理想。

Abstract: Objective To study the control effect of dichlorophacinon ammonium, a new type of anticoagulant rodenticide, to Rattus norvegicus in the special environment. Methods 0.5% salt as attractant, adding to 0.005% dichlorophacinon ammoniumthe mixed poisonous baits including 95% wheat and 5% corn, and kill rodents with one-off application method. Evaluate the control efficacy with rodent trace method. Investigate the population density of R.norvegicust the second month after treatment, and add up six times. Results The rodent density was 55.47% before treatment, while it decreased to 0.78% and 0% after traeatment for 27 d and 40 d, respectively. The rodent density was zero from the second month to seventh month after treatment, and the control effect reached 100%. Conclusion The dichlorophacinon ammonium had the high toxicity and good palatability to R.norvegicus, which had good control efficacy in the special environment.
