SummaryThe contribution of ovaries and ovarian ecdysteroids to dominance and nest initiation was tested in foundresses of Polistes gallicus at the end of hibernation. Removal of the ovaries resulted in a significant decrease of the ecdysteroid titre in haemolymph. Dominance in ovariectomized foundresses was found to be closely correlated to the size of corpora allata. The operated wasps started nest building, but they did not show any egg-laying behaviour. We conclude that both juvenile hormone and ovarian ecdysteroids contribute to degree of dominance, and that factors other than ovary development may stimulate building.
