Abstract: | Pheromones produce dramatic behavioral and physiological responses in a wide variety of species. Releaser pheromones elicit
rapid responses within seconds or minutes, while primer pheromones produce long-term changes which may take days to manifest.
Honeybee queen mandibular pheromone (QMP) elicits multiple distinct behavioral and physiological responses in worker bees,
as both a releaser and primer, and thus produces responses on vastly different time scales. In this study, we demonstrate
that releaser and primer responses to QMP can be uncoupled. First, treatment with the juvenile hormone analog methoprene leaves
a releaser response (attraction to QMP) intact, but modulates QMP’s primer effects on sucrose responsiveness. Secondly, two
components of QMP (9-ODA and 9-HDA) do not elicit a releaser response (attraction) but are as effective as QMP at modulating
a primer response, downregulation of foraging-related brain gene expression. These results suggest that different responses
to a single pheromone may be produced via distinct pathways. |
