Hello All ! About grafting larvae for queen rearing ... It's well known that the small grafted larvae are very resistant and can remain even some hours out of the cluster. The conditions : wetting and low temperature. Does anyone know about the limits of these resistance and maybe some *references* concerning this subject. I know about a serial of cells forgotten overnight in the wet grass and giving good results after introducing in the morning in a queenless colony. My questions : Do people know the maximum time to keep cold these larvae and then obtain a correct queen yet ? Do poeple know about the ideal cold temperature to keep them ?
