Abstract:

Objective To compare field rodent control efficacy using various methods and provide scientific data for deratization in the future. Methods To observe the change of rat density before and after deratizatio at the experimental animal center from September to November 2015. Glue rat board was continuously used in the finished feed warehouse, using bromadiolone baits in raw material storehouse, production workshop using the mousetrap method, the conventional animals feeding chamber by cage-trap. Results A total of 122 rats were captured in 18 d, after deratization average rat density dropped to 6.8% from 59.1% prior to the deratization; corrected deratization rate was 79.2%. Peak was in first day by three physical deratization methods, after a downward trend, the rat density were significantly lower after deratization, but did not reach the standard (≤3%). Dead rats were found after 3 d using bromadiolone baits, 5-6 d to peak, rat density decreased to 0 after deratization. Conclusion Various methods used for prevention and control of rodents obviously reduced the density of rodents. The deratization methods which fit different environments were screened according to the feeding habit, in order to choose rodent bait and control devices efficiently.

摘要：

目的 比较多种方法的现场灭鼠效果，为今后灭鼠工作提供科学依据。方法 2015年9－11月在新疆实验动物中心成品库采用连续投放粘鼠板进行灭鼠，原料库采用溴敌隆毒饵灭鼠法，生产车间采用鼠夹法，普通级动物饲养室采用捕鼠笼法，观察灭鼠前后的鼠密度变化。结果 现场灭鼠18 d共发现死鼠122只，灭鼠后平均鼠密度由灭鼠前的59.1%下降至6.8%，校正灭鼠率为79.2%；3种物理灭鼠法布放器械第1天捕获鼠数量出现峰值，后呈下降趋势，灭后鼠密度均明显下降，但均未达标（≤3%）；投放溴敌隆毒饵第3天开始发现死鼠，第5、6天达到峰值，灭后鼠密度下降为0。结论 采用多种方法对鼠类进行综合防治，可明显降低鼠密度；通过掌握不同环境中鼠类的取食习性，筛选出适合该环境的灭鼠方法，科学合理地选择防治药械。
