Viruses of the honeybee, Apis mellifera L. are known to reside at low levels in colonies, typically showing no apparent signs of infection. Chronic paralysis virus(CBPV) is known to induce significant losses in honey bee colonies. The pathology is characterized by clusters of trembling, flightless, crawling bees and by individual bees, sometimes hairless, standing at the hive entrance. A minusstrand-specific RT-PCR was used to assess viral replication. This is the first report on the infection of CBPV in Korea. Using (-)RT-PCR, 27 apiaries in korea were screened for the honeybee viruses, with positive colonies being analysed for viral genetic diversity. We got 550-nt PCR product from CBPV genomic RNA. Nucleotide sequences were aligned to the complete CBPV genomic RNA sequence deposited in the GenBank database and was revealed 96%(AM-CBPV) identity, respectively. Sequence comparison with other CBPV and honeybee virus.
