Overview of the experimental effects on pathogen loads and expression of genes related to health. Arrows indicate significant main effects in the indicated direction and crosses indicate interaction effects. “Develop” = Migratory relative to stationary management during development, “Adult” = Migratory relative to stationary management during adulthood, “Age” = 28-day old compared to 14-day old, “Behavior” = Forager relative to in-hive worker, “Season” = July relative to May.
