Abstract: Object: To inquire into the influence of deratization on the community structure of domestic rodents. Method:Poison rice bait of 0.005% Bromadiolone was used for killing rats with surplus baiting method, for three days, and then the investigation was carried out on the community structure of domestic rodents every months followed. Result:In the suburbs resident area, in which rats killing sufficiently,variation of the community structure of domestic rodents occurred evidently,and Rattus rattoides invaded extensively indoor. It caused that R.rattoides, instead of Rattus flavipectus and Rattus norvegicus, became dominant in the community of domestic rodents. While in those areas,in which rats killed insufficiently, no invading of R.rattoides was detected. Conclusion:Invading indoor of wild rats will be occurred in suburbs resident area after killing rats sufficiently, which cause the variation of community structure in domestic rodents.
