Abstract: Objective To study the resistances of Rattus norvegicus to first generation anticoagulant rodenticide in Beijing.Methods No-choice-feeding tests on R.norvegicus were carried out by using 0.005% Warfarin bait for 6 days.After the completion of the poison bait feeding period the survival animals were fed on plain food and observed for 14 days.Times to death were recorded during test period.Results All of 24 R.norvegicus tested were killed,and the average lethal doses and the average lethal-time were 14.33 mg/kg and 4.63 days respectively.Conclusion The rats in Beijing to the first generation anticoagulant were still susceptibile and the anticoagulant rodenticide can be applied continuosly.
