【Abstract】Objective 　In Zhanjiang proper , the first generation anticoagulant rodenticide (mainly diphacinoneNa) had been used for more than 20 years. To investigate the resistance of Rattus f lavipectus and R. norvgicus to the first generation rodenticide after Bromadiolone (a second generation anticoagulant rodenticide) were used for 4 years. Methods No2choice feeding tests were carried out and the results obtained compared with those 4 years ago. Results The resistance of the two commensal rodent species ,espcially R . f lavipectus ,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.
