Abstract: Objective In Zhanjiang proper,the first generation anticoagulant rodenticide (mainly diphacinone-Na) had been used for more than 20 years. To investigate the resistance of Rattus flavipectusandR.norvgicusto the first generation rodenticide after Bromadiolone (a second generation anticoagulant rodenticide) were used for 4 years. Methods No-choice feeding tests were carried out and the results obtained compared with those 4 years ago. Results The resistance of the two commensal rodent species,espciallyR.flavipectus,to the first generation rodenticide have declined. Conclusion In the areas where resistance of commensal rodents to the first generation rodenticide had evaluated,After Bromadiolone was used for a few years,the resistance should be slow down could hold back.
