目的 :观察不同养猫覆盖率与鼠密度的关系 ,提出农村长期控制鼠密度方案。方法 :灭鼠前选择不同养猫户覆盖率的点 ,夹夜法调查鼠密度。结果 :鼠密度随养猫覆盖率的增加而减小。结论 :为了使农村鼠密度长期维持在较低水平 ,每年除两次大面积统一用化学灭鼠 ,进行环境治理外 ,提倡户户养猫控制鼠密度。
OBJECTIVE: To observe the relationship between the coverage of different cats and the density of mice, and to propose a long-term control program of rodent density in rural areas. Methods: Choose the point of coverage of different cats before deratization, and investigate the density of rats by the method of nocturnal catgut. Results: Rat density decreased with increasing cat coverage. Conclusion: In order to maintain the density of rural rats at a low level for a long period of time, in addition to two large-scale chemical rodenticides in a large area and the environmental management, the control of the density of rodents in households should be promoted.
