体外寄生虫瓦螨是世界广大地区蜜蜂的最大生物威胁。最近，对自然抗螨种群的研究引起了人们的极大兴趣，以了解自然选择对限制螨种群的机制的作用。在这项研究中，A. mellifera–V 的成分。对乌拉圭两个地区的抗性和易感蜜蜂种群中的破坏子关系进行了彻底的检查和比较。抗螨蜜蜂比易感蜜蜂具有更大的行为抵抗力（卫生和梳理行为）。夏末，与易感蜜蜂相比，抗性蜜蜂的螨虫较少，变形翅病毒 (DWV) 病毒载量也较低。 DWV 变体 A 是在蜜蜂和螨虫中唯一检测到的变体。短串联重复的分子分析表明，抗性蜜蜂是非洲化的（A. m. scutellata 杂交种），而易感蜜蜂则更接近欧洲亚种。此外，螨种群之间也发现了显着的遗传分化。获得的结果表明，乌拉圭蜜蜂对破坏弧菌的天然抵抗力取决于多种因素，并且两种生物体的遗传变异可以发挥相关作用。
The ectoparasite Varroa destructor is the greatest biotic threat of honey bees Apis mellifera in vast regions of the world. Recently, the study of natural mite-resistant populations has gained much interest to understand the action of natural selection on the mechanisms that limit the mite population. In this study, the components of the A. mellifera–V. destructor relationship were thoroughly examined and compared in resistant and susceptible honey bee populations from two regions of Uruguay. Mite-resistant honey bees have greater behavioral resistance (hygienic and grooming behaviors) than susceptible honey bees. At the end of the summer, resistant honey bees had fewer mites and a lower deformed wing virus (DWV) viral load than susceptible honey bees. DWV variant A was the only detected variant in honey bees and mites. Molecular analysis by Short Tandem Repeat showed that resistant honey bees were Africanized (A. m. scutellata hybrids), whereas susceptible honey bees were closer to European subspecies. Furthermore, significant genetic differentiation was also found between the mite populations. The obtained results show that the natural resistance of honey bees to V. destructor in Uruguay depends on several factors and that the genetic variants of both organisms can play a relevant role.
