The pollen beetle is the most important pest in Danish oilseed rape fields. In 2001, we screened a broad range of pollen beetle populations for pyrethroid and dimethoate resistance. A standard dip-test was used to test insecticide resistance in 18 populations collected from oilseed winter and spring rape fields. The beetles were treated with four different insecticides: the pyrethroids tau-fluvalinate, lambda-cyhalothrin and esfenvalerate, and the organophosphate dimethoate. The results show that up to 99% of the pollen beetles survived Danish standard doses of pyrethroids and up to 36% of the beetles survived standard doses of dimethoate.
花粉甲虫是丹麦油菜籽田最重要的害虫。2001年，我们针对拟除虫菊酯和乐果抗性，对大量花粉甲虫种群进行了筛查。采用标准浸液试验，对从冬油菜和春油菜田采集的18个种群的抗药性进行了检测。用四种不同的杀虫剂处理这些甲虫：拟除虫菊酯类的氟胺氰菊酯、高效氯氟氰菊酯和乙氰菊酯，以及有机磷类的乐果。结果表明，高达99%的花粉甲虫能在丹麦标准剂量的拟除虫菊酯中存活，高达36%的甲虫能在乐果标准剂量中存活。
