摘要
目的实验室比较急性灭鼠剂磷化锌与4种抗凝血灭鼠剂毒饵敌鼠钠盐、杀鼠灵、杀鼠迷和溴敌隆对大仓鼠的毒效。方法将1%磷化锌、0.005%溴敌隆和0.025%敌鼠钠盐、杀鼠灵、杀鼠迷配成毒饵,对靶鼠单笼饲养进行有选择摄食试验:抗凝血鼠药摄食4d,磷化锌摄食12h;以毒杀率和摄食系数评价各种药物的毒效和适口性。结果5种鼠药对试鼠的毒杀率:敌鼠钠盐和溴敌隆均为100%,磷化锌为88.89%,杀鼠迷和杀鼠灵分别为50%和10%;摄食系数:磷化锌、敌鼠钠盐、杀鼠灵、杀鼠迷及溴敌隆分别为0.73、0.38、0.64、0.56和0.81。结论除杀鼠灵和杀鼠迷外,其他3种鼠药都适于防治大仓鼠;但从灭鼠成本和易用性考虑,敌鼠钠盐为首选。
Objective To compare the effect of 5 rodenticide baits （zinc phosphide at 1%, diphacinone Na-salt, warfarin and coumatetralyl all at 0. 025 %, bromodiolone at 0. 005 % ） against Tscheskia triton in laboratory. Methods The choice-feeding tests were conducted for single T. triton by feeding 4 anticoagulant rodenticides for ＆days and zinc phosphide for 12 hours. The toxicity and palatability of tested rodenticides was evaluated with killing rate and feed coefficient. Results The killing rates of five rodenticide to T. triton were as follows： 88.89% for zinc phosphide, 100% for diphacinone Na-salt and Bromodiolone, 50 % for coumatetralyl and 10 % for warfarin respectively. The feed coefficients of zinc phosphide, diphadnone Na-salt, warfarin, coumatetralyl and bromodiolone were 0.73,0.38,0.64,0.56 and 0.81 respectively. Conclusion Other three rodenticides could be applied to control T. triton except for coumatetralyl and warfarin. However, considering control cost and practicability, diphacinone Na-salt was the best choice.
