一艘鼠患严重船舶的熏蒸处理

Sulfuryl fluoride fumigation for ships with heavy rodent infestation at Tianjin port

目的了解硫酰氟对船舶上鼠类熏蒸处理效果。方法采用鼠迹法和粘鼠板调查鼠密度;密闭空间硫酰氟药量按照56g/m3对船舶进行熏蒸处理10h。结果该船舶厨房、餐厅、食品库存在大量鼠粪,生活区鼠类活动痕迹明显,10张粘鼠板中7张有鼠类活动痕迹,鼠患严重。熏蒸处理后发现死鼠16只,对照用的8只大白鼠也全部死亡,本次熏蒸取得理想的除鼠效果。结论在鼠密度严重超标或有鼠传疾病发生的情况下,使用硫酰氟熏蒸处理能有效杀灭船舶上的鼠类。
