Artificial Diets Modulate Infection Rates by Nosema ceranae in Bumblebees [PDF]

open access: yesMicroorganisms, 2020
Parasites alter the physiology and behaviour of their hosts. In domestic honey bees, the microsporidia Nosema ceranae induces energetic stress that impairs the behaviour of foragers, potentially leading to colony collapse. Whether this parasite similarly affects wild pollinators is little understood because of the low success rates of experimental ...
