Abstract: Objective To investigate the change of the density of rodents before and after the 2nd phase water storage in Three Gorges reservoir. Methods Mousetraps were used to detect the density of rodents in different periods,and Bromadiolone was applied in large area before water storage. Results The indoor density of rodents before water storage is 4.07%,while it is 3.17% after water storage;the outdoor density of rodents before water storage is 3.17%,and it is 2.35% after water storage. Conclusion The density of rodents in Three Gorges reservoir before and after the 2nd phase water storage do not change greatly.
