title: Prevalence and distribution of six bee viruses in Korean Apis cerana populations.
abstract: The prevalence and distribution of six bee viruses was investigated in 527 Apis cerana samples which were collected from five provinces in South Korea. The most prevalent virus, black queen cell virus (BQCV), was present in 75.11% of 446 adult bee samples, followed by sacbrood virus (SBV) in 30.71%. Deformed wing virus (DWV), Kashmir bee virus (KBV), and chronic bee paralysis virus (CBPV) were present at lower levels of 8.07%, 1.56%, and 0.44%, respectively. The most prevalent virus in 81 larvae samples was SBV, with an incidence of 60.49%, followed by BQCV in 48.14%, DWV in 6.17%, and KBV in 1.23% of samples. CBPV infection was not detected in larvae samples, and acute bee paralysis virus (ABPV) was not present in both larvae and adult bee. Simultaneous infections with up to four viruses were also identified. Of these, infections with SBV and BQCV were most frequent in 25.61% of samples. The distribution of these viruses varied considerably throughout the geographic regions investigated. The three provinces of Gyeongbuk, Jeonnam, and Chungbuk had the highest frequency of bee viruses.
