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 explore the importance of building and improving rodent control facilities on rodent density. Methods Five farm rats were harmed, and all the 8 access points, such as doors, windows and sewers leading to the interior, were examined for the presence of rodent control facilities and whether they were perfect or not. The rat density data since 2009 were also investigated. Results All the five farms except for two built rodent nets in the sewers. No other rodent control facilities were adopted in the other five farms. The highest failure rate of rodent control facilities in key rooms was 37.6% and the lowest was 21.8%. Although five large-scale drug rodenticides are basically taken in five farms each year since 2009, there is a sign that the rodent densities are high before extinction and low after extinction, which can not be maintained at a low level for a long time. Conclusion It is an important factor to control the density of indoor rats to strengthen the construction of anti-rat facilities and improve their anti-rat ability.
