The mite Varroa destructor is the main pest causing damage to apiculture worldwide. In Brazil and other parts of the world, where bees of African origin and their hybrids predominate, the bees can survive these mites without treatment. Studies have shown a correlation between the various genotypes of the mite and its fertility in different geographical regions. Information about mite genotype could be helpful in understanding the diverse effects and relationships of the mite with bees in different regions of the world. DNA analysis by RAPD technique has permitted identification of three distinct genotypes in the mite V. destructor, namely Russian, Japanese and Papua New Guinea. We found predominance of the Russian genotype in Brazil, along with other parts of South America, and in Cuba and Mexico. The Japanese genotype was exclusively found on Fernando de Noronha Island in Brazil.
狄斯瓦螨是全球养蜂业遭受破坏的主要害虫。在巴西和世界其他地区，非洲原产蜜蜂及其杂交品种占主导地位，这些蜜蜂无需治疗就能在这些螨虫侵害下存活。研究表明，螨虫的不同基因型与其在不同地理区域的繁殖力之间存在关联。螨虫基因型的信息有助于理解螨虫在世界不同地区与蜜蜂的多样影响及关系。通过随机扩增多态性DNA（RAPD）技术进行的DNA分析已鉴定出狄斯瓦螨的三种不同基因型，即俄罗斯型、日本型和巴布亚新几内亚型。我们发现俄罗斯基因型在巴西、南美洲其他地区、古巴和墨西哥占主导地位。日本基因型仅在巴西的费尔南多·迪诺罗尼亚岛被发现。
