用抗凝血灭鼠剂毒饵进行旅客列车灭鼠试验。3种毒饵剂型试验11列客车:0.01%大隆石蜡毒饵块处理4列,0.025%杀鼠灵石蜡毒饵块处理4列,0.025%杀鼠灵颗粒毒饵处理3列。毒饵装到纸板盒里,放在车厢夹层和茶几或餐桌下的双暖管之间。投药后每隔15天或30天检查一次消耗,吃光的饵点补充,变质的毒饵更换;在投饵和检查消耗的同时,用粉迹法调查鼠密度。试验结果,3种毒饵灭鼠效果差别很大。以大隆蜡块效果最好:处理15天,平均鼠密度从60.5%降至24.2%;30天降至2.4%。杀鼠灵蜡块处理15天,平均鼠密度从57.5%降至40.0%;30天和90天分别降至9.3%和5.7%。杀鼠灵颗粒效果最差,投药后15天平均鼠密度没有下降,30天由42.1%降至26.3%,60天和90天处理期才分别降至21.1%和13.2%。文中详细讨论了导致效果差的原因。
Passenger train rodent control with anticoagulant rodenticide bait. Three kinds of poison bait formulations test 11 bus: 0.01% Dalong paraffin bait block treatment 4, 0.025% warfarin paraffin block treatment 4, 0.025% warfarin particles bait treatment 3. Put the bait into the cardboard box, between the mezzanine compartment and the double warmer under the coffee table or under the table. Dosing every 15 days or 30 days after a check consumption, eaten bait point supplement, metamorphic poison bait replacement; in the feeding and examination of consumption at the same time, with the gossamer method to investigate the density of rats. Test results, three kinds of bait rodent control vary widely. Dalong wax block best: 15 days of treatment, the average rat density decreased from 60.5% to 24.2%; 30 days to 2.4%. Warfarin wax block for 15 days, the average rat density decreased from 57.5% to 40.0%; 30 days and 90 days were reduced to 9.3% and 5.7%. Warfarin granules had the poorest efficacy. The mean rat density did not decrease 15 days after dosing, from 42.1% to 26.3% in 30 days, and dropped to 21.1% and 13.2% in 60 days and 90 days respectively. The article discusses in detail the reasons for the poor results.
