Chronic parasitization by Nosema microsporidia causes global expression changes in core nutritional, metabolic and behavioral pathways in honey bee workers (Apis mellifera) [PDF]

, 2013
BACKGROUND: Chronic infections can profoundly affect the physiology, behavior, fitness and longevity of individuals, and may alter the organization and demography of social groups.

Honey bee genotypes and the environment [PDF]

, 2014
Although knowledge about honey bee geographic and genetic diversity has increased tremendously in recent decades (Meixner et al., 2013), the adaptation of honey bees to their local environment has not been well studied.

Stable genetic diversity despite parasite and pathogen spread in honey bee colonies [PDF]

, 2015
In the last decades, the rapid spread of diseases, such as varroosis and nosemosis, associated with massive honey bee colonies mortality around the world has significantly decreased the number and size of honey bee populations and possibly their genetic ...

Nosema apis and Nosema ceranae in Beehives of the Apulian Region of Italy: How Citizen Science Can Support Scientific Research

Agriculture
Nosema apis and Nosema ceranae are two well-known pathogens affecting the health of honeybees. To help understand how honeybee colonies are affected by these pathogens, the aim of this study was to analyze the impact of Nosema ceranae and Nosema apis in ...

Recent Advances in the Biocontrol of Nosemosis in Honey Bees (Apis mellifera L.)

Journal of Fungi, 2022
Nosemosis is a disease triggered by the single-celled spore-forming fungi Nosema apis and Nosema ceranae, which can cause extensive colony losses in honey bees (Apis mellifera L.). Fumagillin is an effective antibiotic treatment to control nosemosis, but

Sublethal effects of acaricides and Nosema ceranae infection on immune related gene expression in honeybees [PDF]

, 2016
Nosema ceranae is an obligate intracellular parasite and the etiologic agent of Nosemosis that affects honeybees. Beside the stress caused by this pathogen, honeybee colonies are exposed to pesticides under beekeeper intervention, such as acaricides to ...

Drivers of Viral Prevalence in Landscape‐Scale Pollinator Networks Across Europe: Honey Bee Viral Density, Niche Overlap With This Reservoir Host and Network Architecture

Ecology Letters, Volume 29, Issue 1, January 2026.
Viral spill‐over from honey bees is a potential threat to wild pollinators. We used causal modelling approaches to detect the main drivers of spill‐over. Honey bee viral density, niche overlap with honey bees, urbanisation and plant‐pollinator network structure all played an important role in the transmission of BQCV, DWV‐A and DWV‐B.

A Comparative Study of Environmental Conditions, Bee Management and the Epidemiological Situation in Apiaries Varying in the Level of Colony Losses

Journal of Apicultural Science, 2014
Explaining the reasons for the increased mortality of the honey bee (Apis mellifera L.) in recent years, in Europe and North America, has become a global research priority in apicultural science.
