Dupa 12 cicluri am ajuns si eu la aceeasi concluzie:
Supersedure queens are raised when the bees are unhappy with the
performance of the current queen and decide to replace her. Evidently the
queen must not be doing exactly what the bees expect of her. A number of
reasons might account for this, such as physical condition of the queen
(missing a leg or wing), old age, disease such as nosema, depleted
spermatheca, poorly bred queen (developed from old larva rather than new
larva), not making enough pheromones, or even no new bees emerge for 21
days following introduction of a package in a new hive
Usually a queen that is being replaced through supersedure is failing in some
way, perhaps is old and is deficient in egg laying.However, on occasions,
bees will supersede young, vigorous and good laying queens. We cannot tell
all the subtilities, such as level of queen pheromon e, just by looking at the
brood pattern. Maybe she is laying fine, but not producing enough
pheromones to satisfy the bees of the hive, or she is infested with nosema or
viruses. One will also, at times, observe a queen with a poor brood pattern,
but who is still not being superseded.
Perhaps she is still producing plenty of queen pheromone and that is probably the
most important factor. Perhaps there is nothing wrong with the queen. It could be
that the queen is from highly hygienic stock. There may be mites, disease,
or poisoning in the brood and the bees are cleaning up all the affected
larvae and pupae so you don’t notice, or perhaps the colony does not perceive
that the conditions are just now proper for replacing the queen and having her
mate successfully

The literature is weak on guidelines for determination of supersedure versus swarm cells.The best we can do is describe how most colonies implement supersedure. That’s more than you will get from the popular reference literature.The colony that decides their queen is not up to the task at hand starts supersedure promptly.
