Queen honeybees (Apis mellifera) have a much longer lifespan than worker bees. Whether cellular degradation activity is involved in the longevity of queen bees is unknown. In the present study, cellular degradation activity was evaluated in the trophocytes and oenocytes of young and old queen bees. The results indicated that (i) 20S proteasome activity and the size of autophagic vacuoles decreased...
The trophocytes and fat cells of honeybees (Apis mellifera) have been used in cellular senescence studies, but the changes of cellular degradation activity with aging in workers are unknown. In this study, cellular degradation activity was evaluated in the trophocytes and fat cells of young and old workers reared in a field hive. The results showed the following: (1) 20S proteosome activity decreased...
Honeybees (Apis mellifera) are an attractive model system for studying aging. However, the aging level of worker honeybees from the field hive is in dispute. To eliminate the influence of task performance and confirm the relationship between chronological age and aging, we reared newly emerged workers in a thermostat at 34°C throughout their lives. A survivorship curve was obtained, indicating that...
