It's an early study that deserved my attention. There is no match in advanced title search. I believe it has interest to some of us.


REQUEENING HONEY BEE COLONIES WITHOUT DEQUEENING
By I. W. FORSTER* (Received 15 October 1971)

ABSTRACT
Two-storeyed colonies can be successfully requeened by raising
the original queen and the brood nest above a division board, rearing a young queen from an introduced cell in the bottom storey, and then reuniting both storeys when most advantageous. There is no need to
find queens, and colony manipulation is reduced to a minimum.
