Trials of rodenticidal baits containing 50 p.p.m. difenacoum, 50 p.p.m. bromadiolone or 20 p.p.m. brodifacoum were carried out on farmsteads against populations of Rattus norvegicus containing difenacoum-resistant individuals. Six difenacoum treatments failed in 14--42 days of baiting. Two treatments with bromadiolone succeeded in 23 and 33 days, but four further treatments lasting 35--56 days failed to eradicate the populations. Brodifacoum gave virtually complete control of six populations in 21--73 days and of the ten residual populations left behind by the other two compounds, after baiting for a further 11--85 days. The performance of both bromadiolone and brodifacoum was well below that reported by previous investigators, indicating the possibility of low-grade resistance to these compounds in the difenacoum-resistant strain.
在农场对含有抗敌鼠隆个体的褐家鼠种群进行了含50 ppm敌鼠隆、50 ppm溴敌隆或20 ppm溴鼠灵杀鼠饵剂的试验。六种敌鼠隆处理在投饵14 - 42天内失败。两种溴敌隆处理分别在23天和33天成功,但另外四种持续35 - 56天的处理未能根除鼠群。溴鼠灵在21 - 73天内几乎完全控制了六个鼠群,在对另外两种化合物留下的十个残留鼠群再投饵11 - 85天后也将其几乎完全控制。溴敌隆和溴鼠灵的效果均远低于先前研究者的报告,表明在抗敌鼠隆品系中可能存在对这些化合物的低水平抗性。
