Molecular Detection of Nosema spp. in Honey in Bulgaria
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 ...

Unity in defence: honeybee workers exhibit conserved molecular responses to diverse pathogens [PDF]
This is the final version of the article. Available from the publisher via the DOI in this record.Background: Organisms typically face infection by diverse pathogens, and hosts are thought to have developed specific responses to each type of pathogen ...

Nosema ceranae Escapes Fumagillin Control in Honey Bees
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
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]
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.

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
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 ...

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 ...
