Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

Determination of Nosema Disease in Colonies of Kırşehir Province

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2017
The aim of the study was to determine the prevalence of Nosema disease caused by Nosema ceranae and Nosema apis in bee colonies in Kırşehir. A hundred worker honey bee samples were collected from each of 51 beekeepers in 31 locations in 5 provinces of ...

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

Extracts From Grapefruit (Citrus paradisi) Peel via Microwave‐Assisted and Conventional Extractions: Evaluation of Nosema Infection and Toxicity in Honey Bees

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Conventional and microwave‐assisted extractions of grapefruit peels were optimized using response surface methodology (RSM) based on TPC, TFC, and antioxidant activity (DPPH). The phytochemical profiles of the two optimum extracts were characterized via HPLC before evaluating their acute and chronic toxicity, as well as their effects on honey bee (Apis

Efficient Method for the Rapid Purification of Nosema ceranae Spores [PDF]

open access: yesMycobiology, 2017
Nosema ceranae is an obligate intracellular fungal parasite that causes mortality in honey bees and enhances the susceptibility of honey bees to other pathogens. Efficient purification of Nosema spores from the midgut of infected honey bees is very important because Nosema is non-culturable and only seasonably available.

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 ...

Evaluation of Antimicrosporidian Activity of Plant Extracts on Nosema ceranae

open access: yesJournal of Apicultural Science, 2016
Nosemosis is one of the most common protozoan diseases of adult bees (Apis mellifera). Nosemosis is caused by two species of microsporidia; Nosema apis and Nosema ceranae.

RNA Interference-Mediated Knockdown of Genes Encoding Spore Wall Proteins Confers Protection against Nosema ceranae Infection in the European Honey Bee, Apis mellifera

open access: yesMicroorganisms, 2021
Nosema ceranae (Opisthosporidia: Microsporidia) is an emergent intracellular parasite of the European honey bee (Apis mellifera) and causes serious Nosema disease which has been associated with worldwide honey bee colony losses.

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 ...

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.
