Abstract: 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.
