Effect of the queen on worker reproduction and new queen production in the bumble bee Bombus terrestris Inra
Lopez-Vaamonde, C.; Brown, R.M.; Lucas, E.R.; Pereboom, J.J.M.; Jordan, W.C.; Bourke, A.F.G..
We tested the hypotheses that a non-volatile pheromone inhibiting worker egg-laying and queen development produced by Bombus terrestris queens has effects transferable (a) from workers to other workers or larvae, or (b) on wax. We subdivided small, young colonies with a single mesh screen (Experiment 1) and larger, older colonies with a double mesh screen (Experiment 2). One treatment (in both experiments) involved the transfer of workers, and one treatment (in Experiment 2 only) involved the transfer of wax, from the queenright to the queenless compartments. Queenlessness induced significantly earlier onset of worker aggression (followed by egg-laying) in all treatments in both experiments, and significantly earlier queen production in all treatments in...
