Abstract: Objective:To study the resistance and different effect of anticoaglant rodenticide.Methods:Tests of optional and nonoptional taking food.Results:Resistance of three commensal rodent species was not difference for the ten years in Qichun.However,average rate lethal dose of pure drug to tested rodent was obvious drop,average lethal dates were prolong.Killed rate of four anticoagalant rodenticides to Rattus norvegicus was up to 91%,Taking food coefficient at single coop and crovd fence for coumatetralyl were 0.85 and 1.58 respectively;for Bromodiolone were 0.76 and 0.69 respectively,for warfarin were 0.38 and 0.31,for Diphacine Sodium Sait were 0.35 and 0.25.Conclusion:Two tests of anticoagalant shewed that the anticogalant susceptibility for the three species commensal rodent was high in Qichun,and resistance was not happened.The killed rate of the four rodenticide to Rattus norvegicus was high,and the palatable taste of coumatetpalyl was the best in the four species rodicide.
