Abstract: Objective To investigate effects and adaptability of anticoagulant rodenticides baits to Rattus norvegicus in laboratory. Methods 80(♀40,♂40)Rattus norvegicus from the field of Guiyang City,Guizhou Province were divided into 4 groups randomly and warfarin,coumatetralyl,diphacinoneNa and bromadiolone were tested using selective and unselective feeding methods tested. Results Four using anticoagulant rodenticides poison mortalitiy of Rattus norvegicus was above 90%. The ingestion coefficient of coumatetralyl,bromadiolone,diphacinoneNa and warfarin were 1.49,0.67,0.62 and 0.37,respectively. Conclusion Four anticoagulant rodenticides have a obviously effect on Rattus norvegicus. Coumatetralyl bait adaptability is the best than others,but that of bromadiolone decrease.
