Two possible ways of obtaining young queens in laboratory were tested: to rear them in groups of workers, and to make the regular colonies queenless in comparatively early stage of their development.
In 1997 four groups of four workers in each did not accept young diploid larvae either from their maternal colony or from another one. Workers, which already have established dominance in the groups, destroyed the inserted brood and laid their own eggs. The method still should be tested under different conditions, because, exceptionally, larger groups of workers did accept alien brood and raised queens from it.
From 7 colonies deliberately made queenless at the stage of 20 - 30 workers 6 did raise young queens (20-40 per colony) from remaining brood. One colony produced males only. Young queens reared on this way behaved according to the queen-model and were able to start normal colonies.
