Mean time taken to transport half of the brood per day (average of the two observation sessions) for control (red) and treatment (grey) subcolonies. A time of 150 min was reported for observation sessions in which less than half of the brood was transported. Bars with a ↓ or ↓↓ indicate no brood transport occurred at all during either one or both observation sessions. Days 11, 12 and 13 present data following re-introduction of removed workers.
