一次性投放溴敌隆毒饵控制海港鼠害的研究

One-time deployment of bromadiolone for seaport rodent control

目的验证一次性投放溴敌隆毒饵能否控制海港口岸地区鼠害。方法室内采用粉迹法调查鼠密度,室外采用夹夜法调查鼠密度;投饵方式为一次性饱和投放溴敌隆毒饵。结果福建马尾口岸灭鼠效果为37.26%,天津东疆保税港灭鼠效果为95.10%。结论在投放毒饵面积足够大的情况下,一次性饱和投放溴敌隆毒饵可取得满意灭鼠效果。

Objective To confirm whether one-time deployment of bromadiolone is effective in seaport rodent control. Methods Indoor and outdoor rodent density was investigated both indoor using powder tracking and night-trap methods after saturated deployment of bromadiolone baits. Results The killing rates were 37.26% and 95.10%, in Mawei port, Fujian and in Dongjiang port, respectively. Conclusion One-time saturated deployment of a rodenticide in a sufficiently large area may yield satisfying killing effect.
