LABORATORY MEASUREMENT OF HONEYBEE BROOD DISEASE RESISTANCE. 2. UNCAPPING OF FREEZE-KILLED AND LIVE BROOD BY NEWLY EMERGED WORKERD IN CAGES
C P MILNE, Jr
Groups of newly emerged worker honeybees in cages uncapped 40 freeze-killed brood cells significantly faster than 40 live brood cells. Also, workers in acges containing both 20 live brood cells and 20 freeze-killed brood cells uncapped the dead brood significantly faster than the live brood. These findings indicate that the behaviour in laboratory cages is analogous to the colony behaviour.
