Consuming sunflower pollen reduced pathogen infection but did not alter measures of immunity in bumble bees

Certain diets can benefit bee health by reducing pathogens, but the mechanism(s) driving these medicinal effects are largely unexplored. Recent research found that sunflower (Helianthus annuus) pollen reduces the gut pathogen Crithidia bombi in the common eastern bumble bee (Bombus impatiens). Here, we tested the effects of sunflower pollen and infection on two bee immune metrics to determine if sunflower pollen diet drives changes in host immunity that can explain this medicinal effect. Bees were...
