Abstract:		"Honey bee colony health is a function of the individuals, their interactions, and the environment. A major goal of honey bee research is to understand how colonies respond to stress. Individual-level studies of the bee stress response are tractable, but their results do not always translate to the colony level. Nutritional stress is an important factor in colony declines. Nutrition studies are typically conducted on individual nurse workers (nurses), who are primarily responsible for converting pollen into brood. Nurse physiology is sensitive to both pollen and pheromones, which communicate signals among colony members. Here, we asked whether pheromones influence nurse nutrient pathways involved in brood care, and whether diet influences colony communication. We exposed caged, nurse-aged workers to different combinations of pheromones and pollen, and measured traits related to brood care. We found that pheromones enhanced pollen-dependent processes such as hypopharyngeal gland growth and mrjp1 expression, and buffered the negative effects of starvation. Pollen also enhanced how nurse phenotypes respond to pheromones. Therefore, diet and pheromones interact to influence nurse nutritional physiology and aspects of brood care. These findings have implications for studying colony function and health in an increasingly stressful climate"
