Article Synopsis
- Apis mellifera filamentous virus (AmFV) is a double-stranded DNA virus affecting honeybees, specifically studied in Korean colonies for genetic diversity and prevalence.
- Research identified two main genetic lineages of AmFV in Korea, linked to origins in Switzerland and China, with a high nucleotide similarity.
- The infection rate of AmFV in honeybee colonies rose significantly from 33.09% in 2022 to 44.90% in 2023, and the virus was also found in Varroa destructor mites, suggesting they may spread the virus and contribute to other viral infections in bees.
, especially weak ones, are highly vulnerable to mites, which can rapidly infest and consume stored pollen, leading to weakened colonies and potential colony collapse. This study aimed to ascertain and investigate the prevalence of this mite in honeybee colonies across nine provinces in the Republic of Korea (ROK). A total of 615 honeybee colony samples were collected from 66 apiaries during the spring and 58 apiaries during the summer of 2023.

- A new strain of mites, Neocypholaelaps sp. KOR23, was found in honeybee hives in South Korea during May 2023.
- Morphological and genetic tests confirmed their classification within the Neocypholaelaps genus, closely related to a strain from the U.S.
- The study indicates that these mites may carry multiple honeybee pathogens, raising concerns about their role in spreading diseases among bee colonies.
Article Synopsis
- - Lake Sinai Virus (LSV) has been found to have a significant presence among honeybee populations in South Korea, particularly during a period of severe winter loss in 2022, with the highest infection rates among various tested pathogens.
- - The study identified three genotypes of LSV (LSV2, LSV3, and LSV4) and showed that infection rates were particularly high in colonies experiencing severe winter loss compared to those with normal loss.
- - This research provides the first near-complete genome sequences for the Korean strains of LSV and indicates a close genetic relationship between South Korean and Chinese LSVs, suggesting that LSV may contribute to higher mortality rates in affected honeybee colonies.
Article Synopsis
- * A 2022 study in Chungcheongnam Province, South Korea, identified the presence of the Tyrophagus curvipenis mite in honey bee colonies, linking it to high colony mortality in the area.
- * This mite was found to carry two honey bee pathogens, suggesting it could play a role in spreading diseases among honey bees, but more research is needed to determine its direct effects on bee health.
