几种抗凝血杀鼠剂对东方田鼠的毒杀试验

目的为寻求适合东方田鼠的防控技术,应用5种抗凝血杀鼠剂对该鼠进行毒杀试验。方法试鼠全部捕自洞庭湖湖滩,将捕获的东方田鼠随机分组,每种杀鼠剂处理组分别供给5、10、20、40、60g毒饵。结果敌鼠钠盐、特杀鼠2号、杀鼠迷、溴敌隆、溴鼠灵5种抗凝血杀鼠剂对东方田鼠的致死高峰期在2-6d,对东方田鼠的毒杀率达80%以上。结论试验结果表明,5种杀鼠剂均可作为防治东方田鼠的药剂,尤以特杀鼠2号和溴鼠灵为佳。

Toxicity of anticoagulant rodenticides to the Yangtze vole ( Microtus fortis )

Objective The Yangtze vole(Microtus fortis) was one of the main pest rodents in the Dongting Lake region.The voles moved into farmland during the flooded season every year.To control the rodent pest,the toxicity of anticoagulant rodenticides to the Yangtze vole was compared.Methods The voles were captured in the lake beach and divided into 5 groups for each kinds of rodenticide and provided 5 g,10 g,20 g,40 g,60 g anticoagulant rodenticide bait respectively.Results The results showed that 80% voles died by fed with the anticoagulant rodenticide bait,such as sodium diphacinone,No.2 Teshashu,coumatetralyl,bromadiolone,brodifacoum.The peak of vole died was in 2-6 days.Conclusion The anticoagulant rodenticides,especially No.2 Teshashu and brodifacoum,could be used to control the voles in Dongting Lake region.
