It is well-known that worker bees are female but sterile, meaning their ovaries are underdeveloped. Additionally, we know that the queen bee secretes the inhibitory scent and royal substance, both of which always prevent the development of the workers' ovaries. If the queen is lost and these scents disappear, and the workers cannot build royal cells around the young larvae, the workers closest to the lost queen, who have received a portion of the royal jelly given to her, will have their ovaries grow quickly and will be able to lay eggs. This results in what is known as laying workers (pseudo-queens). However, these eggs are unfertilized and therefore produce only males. As a result, the colony will gradually decline as the number of bees decreases.
How to Eliminate Laying Workers
- The colony with this issue is sealed off and moved to another location in the apiary, while a new hive is placed in its original spot, containing sealed brood combs from other colonies, as well as honey and pollen combs.
- The hive with the laying workers is opened, and the combs are shaken over a white cloth. The worker bees will fly back to their original hive, while the laying workers, due to their heavier weight from having ovaries filled with eggs, will fall onto the cloth and will not be able to fly well. The cloth, along with the laying workers, is then folded and disposed of.
- Afterward, a fertilized queen is introduced to the original colony, and the drone brood in the nearby combs is removed. Suitable combs from the old hive are added to the new hive.
