Controlled Queen rearing
I have read that for grafting Queens one must use larvae that are 72 hours old or younger. After this time larvae will be destined to be workers. It is said that the younger the larvae is when started on the path to being a Queen the "stronger" ...better laying...the Queen will be.
If this is the case why not graft the egg itself so it is in the favourable environment to becoming a Queen in the first place? I realize when an egg is deposited it is stuck to the comb cell at the end but surely this positioning could be replicated.
