Abstract - The effect on capping behaviour of the distance between the larva and the cell opening was examined. Shortened brood cells (with reduced depth) were capped earlier than normal cells. After capping, larval weight in shortened cells was lower than in control cells. Larvae of elongated cells were heavier than control larvae after capping. The results indicate that mechanical stimuli play an important role in triggering capping of cells.
