Abstract
We compared the acceptance of 4-day old virgin queens introduced into
mating nucleus hives using natural and artificial queen cells versus a
wooden 3-hole mailing cage, a standard introduction method. The queen cell
methods gave high acceptance (95% and 93% for natural and artificial,
respectively) even though the queen was released from the queen cell
approximately 10 minutes after being introduced into the mating hive. By
contrast, success using mailing cages was significantly lower (47% and
73%) when the queen was released from her cage after 1 hour or 48 hours,
respectively. The equal success rates of the reused and artificial queen
cells suggests that high success is not due to chemicals present in
natural queen cells transferring to the queens. To further investigate why
queen cells give higher introduction success than cages, we introduced
virgin queens into queenless observation hives.Workers attacked only 1 of
12 queens leaving a queen cell whereas 5 out of 6 queens leaving a cage
were attacked.
