目的 :评价防鼠设施好坏与鼠密度的关系。方法 :随机抽查一定数量食品行业整体和单位内部各重点防鼠设施的质量 ,用粉块法和鼠迹法测定鼠密度 ,并设组实验观察。结果 :防鼠设施完全合格的单位与内部重点房间 ,密度远低于防鼠设施不合格者 (P <0 .0 1)。结论 :有完善的防鼠设施能有效抑制鼠情 ,阻隔外鼠入侵 ,利于巩固灭鼠成果。 Objective: To evaluate the relationship between rodent control facilities and rat density. Methods: Randomly inspect the quality of the key rodent prevention facilities in a certain number of food industry as a whole and inside the unit, determine the mouse density by the method of powder block and rat trace, and set up experimental observation. Results: The rodent control facilities were completely qualified units and internal key rooms, the density is much lower than the rodent control facilities failed (P <0. 01). Conclusion: There is a perfect rodent control facilities can effectively inhibit rodents, blocking the invasion of foreign mice, which will help consolidate the results of rodent control.
