Biological control of nosemosis in Apis mellifera L. with Acacia nilotica extract [PDF]

open access: yesScientific Reports
Nosemosis is one of the most devastating diseases of Apis mellifera (Honey bees) caused by the single-celled spore-forming fungi Nosema apis, N. ceranae and N. neumanii, causing a severe loss on the colony vitality and productivity.

So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]

open access: yes, 2014
Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.

Characterizing the Impact of Commercial Pollen Substitute Diets on the Level of Nosema spp. in Honey Bees (Apis mellifera L.). [PDF]

open access: yesPLoS ONE, 2015
Western honey bee (Apis mellifera L.) populations face declines commonly attributed to pesticide, pathogen, and parasite stress. One way beekeepers combat these stressors is by providing supplemental protein diets to honey bee colonies to ensure adequate
