Haven't cruised through this section in awhile. So apologies this response is way late. However, on the subject of caged virgin queens I can offer in retrospect a couple comments/pointers that work for me.
Newly emerged virgins usually die in a matter of hours in the cage, UNLESS you do the following.
- add honey to the cage. If you are using roller cages, notice that the end cap has dimples in it. Fill those dimples with honey. The first thing she does when she emerges is stick her head in a cell and eat. Put honey in the cage for her.
- add attendants to the cage, as a cell. The new queen needs help to get out. The bees will remove, shave the wax over the end of the cell so only her silk cocoon is left. The queen then need only chew the silk to get out. The new queen also needs assistance with grooming and hardening. Unlike a dog, the queen bee cannot lick and groom her abdomen of remnants from her cell development. The attendants do this. I add a minimum of 5 nurse bees to each roller cage before putting the ripe cell in it.
- bank the virgin queens in a queenless colony that has lots of bees. The bees outside the cages will keep them warm and tongue through to the attendants and the queen to feed them.
- Best not to bank the for more than 10 days. Get them into a split or a nuc soon as you can.
- Introduce her into a queenless nuc or split in a JZBZ minicage with a short fuse, single mini marshmallow. AND a some squirts of warm sugar water laced with honeyBhealthy on everybeebody around the cage area. Install the cage in the evening at dusk. Stay out 10 days.
Hope that helps!
