Molecular Detection of Nosema spp. in Honey in Bulgaria

open access: yesVeterinary Sciences, 2021
Environmental DNA (eDNA) analysis is related to screening genetic material of various organisms in environmental samples. Honey represents a natural source of exogenous DNA, which allows for the detection of different honey bee pathogens and parasites ...

Nosema ceranae Escapes Fumagillin Control in Honey Bees

open access: yesPLoS Pathogens, 2013
Fumagillin is the only antibiotic approved for control of nosema disease in honey bees and has been extensively used in United States apiculture for more than 50 years for control of Nosema apis. It is toxic to mammals and must be applied seasonally and with caution to avoid residues in honey.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

open access: yesInsect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

The relationship between managed bees and the prevalence of parasites in bumblebees [PDF]

open access: yes, 2014
Honey bees and, more recently, bumblebees have been domesticated and are now managed commercially primarily for crop pollination, mixing with wild pollinators during foraging on shared flower resources.

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

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 ...

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 ...
