초록

Honey bees play important roles in the maintenance and preservation of agricultural ecosystems because they contribute to fruit and seed production by pollinating crops. However, the bee population has been declining due to rapid climate change. In 2021~2022, unprecedented, large-scale winter colony losses occurred in Korea. Although these winter colony losses have significant damaging effects on agricultural crop production, their cause has not been identified so far. Therefore, this study describes how honey bee mites are directly or indirectly involved in the winter colony losses reported by previous studies. Honey bee ectoparasitic mites cause considerable damage to honey bee colonies and the major mite species in Korea are Varroa destructor and Tropilaelaps mercedesae. Infestation caused by these mites can directly reduce honey productivity by weakening the colony through increased mortality. Similar to those of Korea, there have been several reports of large-scale winter colony losses around the globe.
Although various causes have been suggested for winter colony losses, infestation caused by mites has been considered one of the most important. After considering the main characteristics associated with large-scale winter colony losses in many other countries, mite infestation can be considered one of the major factor for the 2021~2022 winter colony losses in Korea. The damage caused by V. destructor and T. mercedesae was significant in the apiary where the winter colony losses had occurred. When a colony is damaged by honey bee mites, the lifespan of the worker bees is shortened and normal overwintering becomes difficult. In addition, honeybee infestation caused by mites during the September~October period adversely affects the production of healthy and long-lived worker bees that subsequently become winter bees.
