A comprehensive transcriptome data of normal and Nosema ceranae-stressed midguts of Apis mellifera ligustica workers

Data in Brief, 2019
Honeybees are pivotal pollinators of crops and wild flora, and of great importance in supporting critical ecosystem balance. Nosema ceranae, a unicellular fungal parasite that infects midgut epithelial cells of honeybees, can dramatically reduce honeybee

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

Veterinary 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

PBN - Portugal, beekeeping and nosema [PDF]

, 2012
This work aims at carrying out a survey to assess the prevalence of Nosema sp in Portugal. There has been an increasing number of positively lab-identified cases of Nosema in Bee Pathology Laboratories across the country in recent years. However, the

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

Evolutionary 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 ...

First Detection of Nosema Ceranae and Nosema Apis in Greater Wax Moth Galleria Mellonella

Journal of Apicultural Science, 2017
The greater wax moth Galleria mellonella L. (Lepidoptera: Pyralidae), one of the pests of honey bee (Apis mellifera L.) colonies, has spread almost all over the world. Although the G.

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.

Transcriptome Analyses of the Honeybee Response to Nosema ceranae and Insecticides

PLoS ONE, 2014
Honeybees (Apis mellifera) are constantly exposed to a wide variety of environmental stressors such as parasites and pesticides. Among them, Nosema ceranae and neurotoxic insecticides might act in combination and lead to a higher honeybee mortality. We investigated the molecular response of honeybees exposed to N.

Immune priming of honey bees protects against a major microsporidian pathogen

Pest Management Science, Volume 81, Issue 12, Page 7939-7949, December 2025.
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 ...
