Hygienic behavior in honey bees, Apis mellifera, is measured by determining the
rate at which the bees uncap and remove dead sealed brood. We analyzed individual
behavior of house-cleaning Africanized honey bees in order to focus on some
poorly understood aspects of hygienic behavior. Two observation hives, each with
approximately 3,000 individually marked bees, were used in this study. The
efficiency of hygienic behavior was evaluated in hygienic and non-hygienic
strains of bees using two types of combs (new and old), as well as at different
periods of the day (night and day). We also recorded the age of workers that
performed this task of removing dead brood. In both strains, the workers that
performed tasks related to hygienic behavior were within the same age cohort; we
found no influence of age on the amount of time dedicated to the task,
independent of the type of comb or period of the day. The total time from
perforation of the cell capping until the dead brood had been completely removed,
and was significantly shorter during daytime than at night. Hygienic behavior
directed towards dead brood in new combs was also significantly more efficient
(faster) than for brood in old combs. The type of comb had significantly more
effect than did the time of day. We conclude that the type of comb and time of
day should be taken into consideration when evaluating hygienic behavior in honey
bees.
