Thank you Randy for the reply.



I believe the work of Winston was under natural emergency conditions for raising queens from available eggs and larvae in the hive. However for rearing queens, we induce the queen rearing and graft larvae of certain age. Bees will accept the grafted larvae. The classical study by Woyke showed the effect of grafted larvae age on queen quality. Reference: Woyke J. (1971) - Correlation between the age at which honeybee brood was grafted, characteristics of the resultant queens and result of insemination. J. Apic. Res., 10(1): 45-55.  It is also recommended in Laidlaw and Page queen rearing the younger the grafted larvae the better quality of queens. The only thing we have to be careful during grafting is grafting larvae of the same age. Thus we ensure that non will emerge early and destroy the rest of the queens
