We developed a method of production royal jelly in queenright colony without

restriction of the queen. We compared this method with others that produced royal jelly

a) without the queen (queenless colonies) and b) have the queen restricted in triple horizontal colonies.

The production of royal jelly from three (3) queenright colonies was 830 gr (0,205

gr / cell) after 48 graftings. From three (3) queenless colonies we produced 1580 gr

(0,220 gr / cell) after 41 - 50 graftings. The two (2) triple horizontal colonies produced 1297 gr (0,181 gr / cell) after 48 graftings.

The success of this method is based on the use of young queens (less than 1 year

old) so that can accept the artificial queen cells that are grafted. Also it is important to

use at the first (and only the first) grafting a queenless colony which will keep the

grafted queen cells for one day so that increase the acceptance.
