Pesticide and Pathogen Exposure Causes Idiosyncratic Gene Expression Responses Across Four Diverse North American Bumble Bee Species. [PDF]
Mol EcolABSTRACT Bumble bee (Bombus Latreille) populations of certain species have declined precipitously in North America over several decades. Hypotheses for declines include exposure to the pathogen Nosema bombi and neonicotinoid pesticides. Importantly, populations of some bumble bee species remain stable despite their presumed exposure to these same ...

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.

A draft genome of the honey bee trypanosomatid parasite Crithidia mellificae. [PDF]
PLoS ONE, 2014 Since 2006, honey bee colonies in North America and Europe have experienced increased annual mortality. These losses correlate with increased pathogen incidence and abundance, though no single etiologic agent has been identified.

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 ...

Bee Trypanosomatids: First Steps in the Analysis of the Genetic Variation and Population Structure of Lotmaria passim, Crithidia bombi and Crithidia mellificae. [PDF]
Microb Ecol, 2022 Trypanosomatids are among the most prevalent parasites in bees but, despite the fact that their impact on the colonies can be quite important and that their infectivity may potentially depend on their genotypes, little is known about the population ...

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.

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.

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
