초록

Abnormal winter temperatures caused by climate change are one of the main factors in the overwintering failure of honeybees. To overcome this problem, methods of indoor overwintering in constant temperature and humidity cold storage have been developed. However, research for specific indoor overwintering conditions still remained unclear. In this study, we conducted an experiment to determine the conditions suitable for indoor overwintering of honeybees. Honey bees (Apis mellifera) were overwintered in cold storage set to maintain either 1°C or 4°C with 50% relative humidity, and as a control, bees that overwintered outdoors were used to compare the overwintering ability of each conditions. Examination of the daily number of dead bees in indoor overwintering colonies showed that 4°C resulted in approximately three times as many dead bees on average as 1°C. The number of dead bees decreased after moving from 4°C to 1°C. When examining the average weight loss of colonies at the end of overwintering, there was no significant difference between colonies overwintered in outdoor and 1°C cold storage, with a loss of approximately 1.2~1.3 kg. The 4°C colony had a relatively large decrease of about 1.7 kg. These results suggest that 1°C may be more suitable than 4°C for indoor overwintering.
However, there is still a lack of clear evidence that 1°C is better for indoor overwintering. Further research is needed to clarify indoor overwintering conditions.
