Beekeepers need a source of young queens for maintaining productive ho
ney bee colonies. These queens call be bought from large-scale queen p
roducers. In order to produce queens in large numbers, those queen pro
ducers transfer very small worker bee larvae into artificial queen cel
l cups, in a procedure known as grafting. Many beekeepers find graftin
g even a few queens difficult because these small larvae are hard to s
ee. Therefore, many beekeepers cannot duplicate the queen rearing tech
nique employed by large-scale queen producers, but there are alternati
ves.
