目的：探讨灭鼠对家鼠群落结构的影响。方法：采用０．００５％溴敌隆毒米饱和投毒灭鼠，连放３ｄ后，逐月调查家鼠群落结构变化情况。结果：灭鼠较彻底的城郊住宅区，家鼠群落结构发生明显变化，出现黄毛鼠大规模入侵现象，家鼠群落由以黄胸鼠、褐家鼠为优势种，演替为以黄毛鼠为优势种。灭鼠不彻底的地区未出现野鼠入侵现象。结论：在城郊地区进行室内彻底灭鼠，可导致野鼠入侵，引起家鼠群落结构的变化。
Objective: To investigate the effect of deratization on the structure of house mouse. Methods: Saturated poisoning rats with 0.005% bromadiolone were used to rodent control. After 3 days, the changes of the structure of house mice were investigated monthly. Results: The community structure of house mouse evidently changed after the rodent rodent was overdosed. The phenomenon of large-scale rodent invaders occurred. The rodent community was dominated by Rattus flavipectus and Rattus norvegicus, Rat is the dominant species. Incomplete rodent control areas did not appear invaders. Conclusion: Thorough rodent control in the suburbs can lead to the invading of wild rats and cause the changes of the structure of rodents.
