5个农场防鼠设施状况与鼠密度关系分析

Relationship of physical rat-proof and rat density in five farms

目的探讨修建和完善防鼠设施对控制鼠密度的重要性。方法对5个农场鼠重点危害场所,检查所有通向室内的门、窗、下水道等8处通道口,有无防鼠设施以及是否完善,并调查2009年以来的鼠密度资料。结果 5个农场除2家在下水道修建防鼠网外,其他通道均未采取有效防鼠设施,重点房间防鼠设施不合格率最高的为37.6%,最低的为21.8%。2009年以来5个农场虽然每年基本上都采取2次大面积药物灭鼠,但鼠密度都存在着灭前高、灭后低的迹象,不能长久维持在较低水平。结论加强防鼠设施建设,提高其防鼠能力是控制室内鼠密度的重要因素。

Objective To study the effects of physical rat-proof methods in control of rat＇s density. Methods Setting up rodents control equipments in eight passageways inside the five farms, for instance the edges of doors, win- dows and sewers etc. The datas of rat density were collected back to the date of 2009. Results Only two of the five farms had set up rodents control equipments in sewers. Fraction defectiveness of the key cubicles ranged from 21.8% to 37.6%. It was difficult for the five farms to keep in low rat density for twice deratization a year in the past four years. Conclusion Physical rat-proof and rat-proof efficacy are the key points for controlling rat and keeping the density of rat in a low level.
