Abstrakt		Mature honeybees (Apis mellifera L.) old enough to forage (> 3 weeks) were segregated into three activity groups: waggle dancers (active foragers), folowers of the dancers (potential recruits) and resing bees (not involved in foraging). Dopamine (DA) pathways in the brain of honeybees seemed to be involved in regulation of forager recruitment. Brain DA and N-beta-analyldopamine (NBAD) levels in the dancers were always higher than in followers, and an increased number of dancers was observed after feeding the colony dihydroxy-phenylalanine (DOPA). Dopamine is hypothesized to modulate the neural activity in the calyx of the mushroom bodies related to recruitment behavior. No consistant effect of octopamine (OA) or serotonin (5HT) on recruitment behavior was observed. Levels of all biogenic amines were strongly effected by season and day-to-day whether changes. Some diurnal changes were also observed.
