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

Scientific 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]

, 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.

Immune priming of honey bees protects against a major microsporidian pathogen. [PDF]

Pest Manag Sci
We immune‐primed honey bees at two developmental stages in the laboratory and the field with heat‐killed Nosema ceranae spores. When subsequently fed live spores, immune‐primed adults had lower infection levels. Abstract BACKGROUND Honey bees face significant threats from pathogens like Nosema ceranae, a microsporidian parasite that contributes to ...

Features of microsporidia Nosema apis and Nosema ceranae (Nosema species) development of winter bee (Apis mellifera L.) generation

ScienceRise: Biological Science, 2022
Temperature is one of the main abiotic factors affecting the development of causative agents of nosemosis in the bee's body. The aim of the research. To determine the influence of the winter and summer bee nest temperature (20–22 °C and 35–36 °C, respectively) on the duration of Nosema species development of winter bee generation isolated in hoarding ...

The first report of the prevalence of Nosema ceranae in Bulgaria [PDF]

PeerJ, 2018
Nosema apis and Nosema ceranae are the two main microsporidian parasites causing nosematosis in the honey bee Apis mellifera. The aim of the present study is to investigate the presence of Nosema apis and Nosema ceranae in the area of Bulgaria.

Nosemosis in Honeybees: A Review Guide on Biology and Diagnostic Methods

Applied Sciences, 2022
Nosema apis and Nosema ceranae are dangerous parasites of the honey bee (Apis mellifera). N. ceranae is more pathogenic and, nowadays, more widespread than N. apis. There are also cases of mixed infections or infections of only N. apis. Both N.

Prevalence of the Microsporidian Nosema spp. in Honey Bee Populations (Apis mellifera) in Some Ecological Regions of North Asia

Veterinary Sciences, 2020
Two species of microsporidia, Nosema apis and Nosema ceranae, are obligate intracellular parasites that are widespread in the world and cause the infectious disease (Nosemosis) of the Western honey bee Apis mellifera.

Microbial Evolution in Allodapine Bees: Perspectives From Trophallactic, Socially Plastic Pollinators. [PDF]

Evol Appl
ABSTRACT This review seeks a deeper functional understanding of wild bee microbiomes by focusing on a tribe of bees where natural history and behavioral ecology are well known but investigations of microbiology are just beginning. Opportunities to improve our future knowledge of pathogens to insect pollinators are explored—which have broad ...
