Objective To investigate the resistance ofRattus tanezumiandR. norvegicusto bromadiolone in Baoshan district of Shanghai, and to provide a guidance rodenticide application.Methods The experiment was performed according to the non-selective feeding method proposed by national rodent resistance cooperation group.Results All the 21 individuals of R. tanezumiand 20 individuals ofR. norvegicusdied in the observation period, after being fed with 0.005% bromadiolone. The average killing days were 6.3 and 6.7 days, respectively. The average consumptions of bromadiolone were 14.91 and 23.99 mg/kg,respectively. Bromadiolone-resistant R. tanezumior R. norvegicusindividual was not detected.Conclusion Rattus tanezumi and R. norvegicusin Baoshan district of Shanghai are not resistant to bromadiolone. Routine monitoring of bromadiolone resistance should be performed. The first- and second-generation anticoagulant rodenticides should be chosen properly to delay the development and evolution of rodenticide resistance in rodents.
