How to Manage Bee Colonies in Autumn?
1. Replace the Queen Bee Promptly
The queen bee is the main reproducer of the colony. Younger queen bees have better egg-laying capabilities and adaptability compared to older ones. Therefore, replacing old, weak, or sick queens in the autumn is beneficial for the colony's winter survival. However, if the queen was already replaced in the spring, there's no need to replace her again (once a year is sufficient). Additionally, the autumn queen replacement should be done before the last major nectar flow of the year; replacing her too early or too late is not conducive to the colony's development.
2. Ensure More Bees Than Frames
After replacing the queen, remove any excess comb frames from the colony to ensure that there are more bees than comb frames. Some people believe that the more comb frames there are, the faster the colony will develop. In fact, at all times, it’s important to ensure there are more bees than comb frames, or at least have a balance between them. Having more comb frames than bees is detrimental to the colony's development at any time. For Chinese honeybees, it’s best to replace all old comb frames as they prefer new ones.
3. Cultivate Winter Worker Bees
In addition to ensuring sufficient honey storage, it is important to provide incentive feeding in autumn. Feed the colony a small amount of dilute sugar syrup or honey water once daily in the evening. This stimulates the queen to lay eggs and encourages worker bees to rear brood, helping the colony produce a large number of appropriately aged winter bees (the more winter bees, the safer the colony during winter). If the colony’s honey storage is insufficient, provide supplemental feeding first before incentive feeding.
4. Prevent and Control Diseases
Autumn is an advantageous time to prevent and control bee diseases, as well as the best time to manage varroa mites and wax moths. Beekeepers should carry out comprehensive disease and pest control during this period. Autumn is also the season when hornet attacks are most severe (due to the scarcity of external food sources, hornets take risks to attack bee colonies). Beekeepers should actively help colonies defend against hornets and also prevent robbing behavior among bees.
5. Enhance Hive Insulation
Temperatures drop rapidly in late autumn, especially during cold fronts. Some colonies in the north may have already entered the wintering period. Beekeepers should ensure proper insulation of the hives. The inside of the hive can be filled with insulating materials, and the outside can be covered with straw or stalks. Remove all empty comb frames from the hive and promptly repair any gaps. Additionally, reduce the hive entrance size appropriately.
Conclusion
Autumn is a critical period for beekeeping. It not only affects whether the colony can successfully overwinter (the more winter bees, the safer the colony during winter), but also impacts the development of the colony in the coming year (more worker bees after winter means faster colony development). Therefore, beekeepers should not take this season lightly.
