Fungicide consumption exacerbates the negative effects of a common gut parasite in bumble bee microcolonies [PDF]
Royal Society Open ScienceBumble bees face numerous environmental stressors, including gut-parasite infection and exposure to agricultural fungicides, which can negatively impact colony health.

Core symbionts, age at inoculation and diet affect colonization of the bumblebee gut by a common bacterial pathogen. [PDF]
J Anim EcolThis paper examines ecological interactions within the bumblebee gut microbiome and between the microbiome and host using field sampling and controlled experiments. We demonstrate that non‐core bacteria occur frequently in high abundance in wild bumblebee gut microbiomes.

Gut microbiome of Vespa orientalis: functional insights and potential honey bee pathogen dynamics [PDF]
Animal MicrobiomeVespa orientalis, the oriental hornet, is an emerging predator of honey bees whose ecological impact and microbial ecology remain poorly understood. Here, we present the first detailed characterisation of its gut microbiota by integrating 16S rRNA gene ...

Microbiome Structure Influences Infection by the Parasite Crithidia bombi in Bumble Bees. [PDF]
Appl Environ Microbiol, 2018 Recent declines in bumble bee populations are of great concern and have prompted critical evaluations of the role of pathogen introductions and host resistance in bee health.

No evidence of effects or interaction between the widely used herbicide, glyphosate, and a common parasite in bumble bees [PDF]
PeerJ, 2021 Background Glyphosate is the world’s most used pesticide and it is used without the mitigation measures that could reduce the exposure of pollinators to it. However, studies are starting to suggest negative impacts of this pesticide on bees, an essential

Ecological and social factors influence interspecific pathogens occurrence among bees [PDF]
Scientific ReportsThe interspecific transmission of pathogens can occur frequently in the environment. Among wild bees, the main spillover cases are caused by pathogens associated with Apis mellifera, whose colonies can act as reservoirs.

The Pathogens Spillover and Incidence Correlation in Bumblebees and Honeybees in Slovenia
Pathogens, 2021 Slovenia has a long tradition of beekeeping and a high density of honeybee colonies, but less is known about bumblebees and their pathogens. Therefore, a study was conducted to define the incidence and prevalence of pathogens in bumblebees and to ...

Pollen from multiple sunflower cultivars and species reduces a common bumblebee gut pathogen [PDF]
Royal Society Open Science, 2019 Pathogens are one of the factors driving pollinator declines. Diet can play an important role in mediating pollinator health and resistance to pathogens. Sunflower pollen (Helianthus annuus) dramatically reduced a gut pathogen (Crithidia bombi) of Bombus
