ABSTRACT
It has been proposed that a honey bee (Apis mellifera) worker's preference for foraging for pollen or nectar is modulated by a gene network that was originally involved in regulating the reproductive cycles of an ancestral solitary species. We used carbon dioxide to induce narcosis in queens and workers. This treatment is known to initiate oogenesis in queens, reduce oogenesis in queenless workers and to change worker foraging preference. We then assessed changes in gene expression of genes suspected to be involved in either foraging behaviour or reproduction. We show that some genes change expression in the opposite direction between castes in response to treatment. Our results therefore support the hypothesis that reproductive and foraging traits are causally related in the honey bee.
