I have been rearing a few queens this year and have bad some success. I have been grafting about 40 jzbz cups each week. I place the capped cells in an incubator and let the new queens emerge into hair roller cage. I then move the virgin queen into a plastic queen cage and install it in a mini mating nuc. I usually get 30 of the original grafts to this point. But then the difficulty begins with the candy plug. I made plugs made of powdered sugar and honey mixed to a stiff paste and had several virgin queens get stuck in it and die. So I made some plugs with corn syrup and powdered sugar. It is much harder and the queens do not get stuck in it but the bees do not eat it very well and I have had to release her myself after a few days. It is not difficult to release the queens manually but while doing this I have had several virgins fly away when I am opening the mating nuc. Usually 10 out of the 30 virgins get released and are mated but I have the same challenge with the candy plug after I place the mated queen in a 5 frame nuc. So the final success rate is overall pretty poor and most of the failures are because of the candy plug. It seems like simple problem with a simple solution but I am missing something. I would think releasing the queen would be the easy part of queen rearing. I've done it hundreds of times with packages and purchased queens. Any thoughts would be appreciated.
