The Spring Assessment of Nosema Spp. Infection in Honey Bee Colonies (Apis mellifera L.) - Sampling as an Important Aspect of a Reliable Diagnosis

open access: yesJournal of Apicultural Science, 2018
The objective of the research was a comparative assessment of the infection levels of Nosema spp. in honey bees collected from different areas of the hive.

Metabolomics-based biomarker discovery for bee health monitoring : a proof of concept study concerning nutritional stress in Bombus terrestris [PDF]

open access: yes, 2019
Bee pollinators are exposed to multiple natural and anthropogenic stressors. Understanding the effects of a single stressor in the complex environmental context of antagonistic/synergistic interactions is critical to pollinator monitoring and may serve ...

Unraveling Long‐Term Microsporidia Diversity and Dynamics in Lake Aydat (France) Through Paleogenomics

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Sedimentary ancient DNA study revealed 138 years of hidden microsporidian (unicellular eukaryotic parasite) diversity and host–parasite dynamics in a freshwater lake. A major community shift in the 2000s, linked to anthropogenic pressures, shows how paleogenomics reveals the diversity and long‐term ecological trajectories of these previously overlooked

CONTROL AND VIABILITY OF BEE NOSEMOSES

open access: yesArchives of Veterinary Medicine, 2021
Nosemosis is a bee disease practically present in all countries of the world. Control of the presence of Nosema apis and Nosema ceranae is of great importance. The consequences for bees will depend on the degree of infection of the bees colony.Weakening

An update on recent colony losses in Scotland from a sample survey covering 2006-2008 [PDF]

open access: yes, 2010
Peterson et al. (2009) reported figures on honey bee colony losses from a postal survey of beekeepers in Scotland carried out in early summer 2006 on behalf of the Executive of the Scottish Beekeepers' Association (SBA). We now provide updated figures on

Environment and Pollen Diversity Differentially Affect the Gut Microbiomes of Introduced Honeybees and Bumblebees

open access: yesEvolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Invasive species may exhibit shifts in their gut microbiome in response to novel environments and diet, but this may differ across host species and their time since colonisation. We investigate if site environmental variables and foraged pollen resources differentially shape the gut microbiomes of two bee species with contrasting introduction ...

A strong immune response in young adult honeybees masks their increased susceptibility to infection compared to older bees [PDF]

open access: yes, 2012
Honeybees, Apis mellifera, show age-related division of labor in which young adults perform maintenance ("housekeeping") tasks inside the colony before switching to outside foraging at approximately 23 days old. Disease resistance is an important feature

A Review of Nosema cerane and Nosema apis: Caracterization and Impact for Beekeeping

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2019
Two microsporidia have been described infecting honey bees worldwide: Nosema apis and Nosema ceranae. The infecting forms of the parasite are the spores, ingested by the adult host insects. Studies demonstrated that the infection with Nosema spp. range from less than 1 to 100 percent, this disease reduces worker longevity by 22-44% which in turn ...

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

open access: yesEcology 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.
