[Mitarbeiter.zoologie] Crithidia and infection of Bombus

[Christoph]

Hi all,

Happy new year! I hope you are all doing well.

Robert, the Alder group published something on inhibitory effects of
sunflower pollen. Maybe you were referring these publications below?

LoCascio, G. M., et al., 2019. Effect of timing and exposure of sunflower
pollen on a common gut pathogen of bumble bees. Ecological Entomology.
LoCascio, G. M., et al., 2019. Pollen from multiple sunflower cultivars and
species reduces a common bumblebee gut pathogen. Royal Society Open
Science. 6, 190279.

This might also be relevant:
Richardson, L. L., et al., 2016. Nectar chemistry mediates the behavior of
parasitized bees: consequences for plant fitness. Ecology. 97, 325-337

Best wishes,
Christoph
