Parasites are viewed as a major threat to wild pollinator health. While this may be true for
epidemics driven by parasite spillover from managed or invasive species, the picture is more …

Background Plants often use floral displays to attract mutualists and prevent antagonist
attacks. Chemical displays detectable from a distance include attractive or repellent floral …

Plants have unique chemical and physical traits that can reduce infections in animals
ranging from primates to caterpillars. Sunflowers (Helianthus annuus; Asteraceae) are one …

In Europe, honey bees and bumble bees are among the most important pollinators, and
there is a growing interest in understanding the effects of floral resource availability on their …

Floral nectar and pollen commonly contain diverse secondary metabolites. While these
compounds are classically thought to play a role in plant defense, recent research indicates …

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 …

Community diversity can reduce the prevalence and spread of disease, but certain species
may play a disproportionate role in diluting or amplifying pathogens. Flowers act as both …

Commercial bumblebees have become popular models to understand stressors and
solutions for pollinator health, but few studies test whether results translate to other …

Simple Summary Bee declines have been reported worldwide, partly due to parasite spread
induced by human activities. However, bees may forage on specific floral resources to face …

Background Diet and parasitism can have powerful effects on host gene expression.
However, how specific dietary components affect host gene expression that could feed back …
