Bee parasitic mite syndrome is a disease complex of colonies simultaneously infested with Varroa destructor mites and infected with viruses and accompanied by high mortality. By using reverse transcriptional PCR (RT-PCR), W′ve out of seven bee viruses were detected in mite samples (V. destructor) collected from Korea. Samples of Varroa destructor samples were collected at the end of summer following acaricide treatment. In Varroa destructor mites, during the year viruses were found at least sevevn viruses (DWV, IAPV, KBV, CBPV, SBV, CWV, BQCV) of the apiaries. The latter findings support the putative role of mites in transmitting these viruses. Taken together, these data indicate that bee virus infections occurpersistently in bee populations despite the lack of clinical signs, suggesting that colony disease outbreaks might result from environmental factors that lead to activation of viral replication in bees. This is also the first report of bee viruses in mites from Korea.
