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 ...

Variation in the Distribution of Nosema Species in Honeybees (Apis mellifera Linnaeus) between the Neighboring Countries Estonia and Latvia

open access: yesVeterinary Sciences, 2021
The unicellular spore-forming parasites Nosema apis and Nosema ceranae are considered to be one of the causes of increased honey bee mortality in recent years.

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

Nosema apis and Nosema ceranae in Beehives of the Apulian Region of Italy: How Citizen Science Can Support Scientific Research

open access: yesAgriculture
Nosema apis and Nosema ceranae are two well-known pathogens affecting the health of honeybees. To help understand how honeybee colonies are affected by these pathogens, the aim of this study was to analyze the impact of Nosema ceranae and Nosema apis in ...

A survey of Nosema apis infection in apiaries of North Khorasan province, Iran [PDF]

open access: yesThe Iranian Journal of Veterinary Science and Technology, 2012
Nosema apis is an obligate intracellular parasite belonging to phylum Microsporidia. This para site is known as main causative agent of nosemosis in honeybees especially in the European honeybee (Apis mellifera).

Stable genetic diversity despite parasite and pathogen spread in honey bee colonies [PDF]

open access: yes, 2015
In the last decades, the rapid spread of diseases, such as varroosis and nosemosis, associated with massive honey bee colonies mortality around the world has significantly decreased the number and size of honey bee populations and possibly their genetic ...

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.
