We used a cDNA microarray to identify genes expressed in a caste (worker)- and division of labor (nurse bees or foragers)-dependent manner in the honeybee brain. Among the identified genes, one encoded a putative orphan receptor (HR38) homologue that mediates ecdysteroid-signaling. Real-time reverse transcription-polymerase chain reaction indicated that expression of this gene is higher in forager brains, as compared to nurse bees and queens. In the forager brain, expression was concentrated in a subset of the mushroom body neurons, suggesting that ecdysteroid-signaling in the mushroom bodies might be involved in the division of labor of the workers.
