阿拉山口口岸灭鼠效果回顾性分析及鼠情反弹监控的探讨

目的总结、评价灭鼠效果、经验和教训,为持续巩固灭鼠成果及鼠情反弹监控提供科学依据。方法自2005年开始,在口岸城区、郊区及野外阳性点区连续5年的灭鼠、灭蚤,在城区用溴敌隆毒饵,在郊区和野外用人工捕获法、堵洞、投磷化铝和建立砖制溴敌隆毒饵站隔离防护带;将5年前、5年间和5年灭鼠后的鼠情监测结果对比分析。结果 2009年在口岸城区鼠形动物密度由5年前的9.0%降至0.2%,褐家鼠密度由20.0%降至0,染蚤率由93.3%降为0,印鼠客蚤指数由16.27降为0,原有的优势鼠种及媒介印鼠客蚤现已消退,鼠形动物密度是口岸开放20年以来的最低;在郊区灭鼠区鼠形动物密度由6.0%下降到3.0%,野外阳性点大沙鼠密度也由原来的9.0只/hm2下降到2.3只/hm2。结论当前口岸灭鼠措施、技术和药物有效,消除了口岸鼠疫疫情发生的潜在风险;为巩固成果、监控鼠情反弹隐患,探讨了创建口岸鼠防安全五道防线屏障建设。

Retrospective analysis of the rodenticidal effect and rodent infestation monitoring at Alataw Pass

Objective To collect data on from previous practices for sustainable rodent control and monitoring of potential rodent infestation. Methods Rodent and flea control measures were implemented for five consecutive years in urban,rural and wild locations since 2005. Bromadiolone baits were deployed in urban areas and the pests were manually captured,holes blocked,aluminium phosphide applied and isolation belts made up of bromadiolone bait sentinels built in the suburb and field areas. Rodent infestation monitor...
