The article presents the means of Varroa destructor mite transmission as well as the host transfer from the Apis cerana to Apis mellifera bee. It presents a study on the genetic diversity of mites based on the variation of the cytochrome oxidase I (CO I) gene. The investigations resulted in establishing the latest taxonomy of the genus Varroa published in the article and consistent with the National Centre for Biotechnology Information (NCBI) database. The variation of the CO I gene facilitated determination of the haplotype types of mites occurring worldwide. The article describes the developmental cycle and biology of Varroa destructor mites and viruses transmitted by the mites, which pose a threat to bees and cause Colony Collapse Disorder (CCD). The main methods of Varroa destructor mite control are presented.
