油膏灭鼠毒饵现场灭鼠效果研究

Ointment poison bait against rodents in field

目的 评价油膏灭鼠毒饵灭效,为在铁路内推广使用该毒饵提供科学依据。方法 采用饱和投饵法连续7d在车站和旅客列车上投饵,灭前和灭后每日用粉迹法检测鼠密度,比较实验饵与对照饵灭效。结果 实验饵在列车和车站的灭效均达90%以上,而对照饵在列车的灭效仅为71%,在车站的灭效仅为87%。列车对照组与实验组鼠密度比较自灭后第3天均有显著性差异,列车对照组(x2≥21. 55,P<0. 01),车站对照组与实验组鼠密度比较自灭后第3天均有统计显著性差异,车站对照组(x2≥9 .86,P<0. 01)。结论 毒饵的灭效优于对比毒饵,且更适合旅客列车使用。

Objective To evaluate the efficacy of poison bait against rodent, and provide scientific evidence for controlling rodent by using the poison bait in the railway field. Methods By saturation-feeding method, feeding lasting 7d in the railway station and train, examining the density of rodent by powder-trace method in the day before feeding and each day after feeding,compared the efficacy of rodent control between the experimental bait and the contrasting bait. Results The rodent control efficacy of the experimental bait were over 90% in the station and train, but the rodent control efficacy of the contrasting bait was only 71% in the train and 87% in the station. There was statistical significance between the rodent density of the contrasting group and the experimental group in the train each day after feeding 3d(x 2≥21.55,p<0.01). There was statistical significance between the rodent density of the two groups in the station each day after feeding 3d(x 2≥9.86,p<0.01). Conclusion The efficacy of ointment poison bait was better than the contrasting poison bait on rodent control , and it should be used properly in the train.
