is an ectoparasitic mite causing devastating damages to honey bee colonies around the world. Its impact is considered a major factor contributing to the significant seasonal losses of colonies recorded every year. Beekeepers usually rely on a reduced set of acaricides to manage the parasite, usually the pyrethroids tau-fluvalinate or flumethrin, the organophosphate coumaphos, and the formamidine amitraz. However, the evolution of resistance in the mite populations is leading to an unsustainable scenario with almost no alternatives to reach an adequate control of the mite. Here, we present the results from the first large-scale and extensive monitoring of the susceptibility to acaricides in the Comunitat Valenciana, one of the most prominent apicultural regions in Spain. Our ultimate goal is to provide beekeepers with timely information to help them decide what would be the best alternative for a long-term control of the mites in their apiaries. Our data show that there is a significant variation in the expected efficacy of coumaphos and pyrethroids across the region, indicating the presence of a different ratio of resistant individuals to these acaricides in each population. On the other hand, the expected efficacy of amitraz was more consistent, though slightly below the expected efficacy according to the label.
是一种外寄生螨，对世界各地的蜂群造成毁灭性破坏。其影响被认为是导致每年记录的蜂群显著季节性损失的主要因素。养蜂人通常依靠减少杀螨剂的使用来控制这种寄生虫，通常使用拟除虫菊酯类的氟胺氰菊酯或氟氯苯菊酯、有机磷酸酯类的蝇毒磷以及甲脒类的双甲脒。然而，螨种群中抗药性的演变导致了一种不可持续的局面，几乎没有其他替代方法来充分控制螨。在此，我们展示了对西班牙最著名的养蜂地区之一巴伦西亚自治区螨对杀螨剂敏感性进行首次大规模广泛监测的结果。我们的最终目标是为养蜂人提供及时信息，帮助他们决定长期控制其蜂场中螨的最佳替代方法。我们的数据表明，该地区蝇毒磷和拟除虫菊酯的预期功效存在显著差异，这表明每个种群中对这些杀螨剂产生抗性的个体比例不同。另一方面，双甲脒的预期功效更一致，尽管略低于标签上的预期功效。
