Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps. [PDF]

Insect Sci
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...

Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a <i>Bacillus thuringiensis</i>-Based Biopesticide. [PDF]

Ecol Evol
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee

Immune priming of honey bees protects against a major microsporidian pathogen. [PDF]

Pest Manag Sci
We immune‐primed honey bees at two developmental stages in the laboratory and the field with heat‐killed Nosema ceranae spores. When subsequently fed live spores, immune‐primed adults had lower infection levels. Abstract BACKGROUND Honey bees face significant threats from pathogens like Nosema ceranae, a microsporidian parasite that contributes to ...

Infection Prevalence of Microsporidia Vairimorpha (Nosema) spp. in Japanese Bumblebees. [PDF]

Insects, 2023
Microsporidia are spore-forming intracellular parasites of various invertebrates and vertebrates. Vairimorpha bombi negatively affects the fitness of bumblebees and its prevalence correlates with declining bumblebee populations.

Microbial Evolution in Allodapine Bees: Perspectives From Trophallactic, Socially Plastic Pollinators. [PDF]

Evol Appl
ABSTRACT This review seeks a deeper functional understanding of wild bee microbiomes by focusing on a tribe of bees where natural history and behavioral ecology are well known but investigations of microbiology are just beginning. Opportunities to improve our future knowledge of pathogens to insect pollinators are explored—which have broad ...

Specific detection and quantification of three microsporidia infecting bees, Nosema apis, Nosema ceranae, and Nosema bombi, using probe-based real-time PCR

European Journal of Protistology, 2022
Among stressors affecting bee health, Nosema microsporidia are prevalent intracellular parasites. Nosema apis and Nosema ceranae have been described in honey bees (Apis spp.), while Nosema bombi has been described in bumble bees (Bombus spp.). Although available molecular methods serve as a complement to microscopic diagnosis of nosemosis, they do not ...

Dataset of the next-generation sequencing of variable 16S rRNA from bacteria and ITS2 regions from fungi and plants derived from honeybees kept under anthropogenic landscapes

Data in Brief, 2021
Forager Apis melliefera honeybees were collected from four localities located in Europe, i.e.: London, UK; Athens, Greece; Marchamalo, Spain and Lublin, Poland. Furthermore, from Asia we have collected A. mellifera as well as A.

Amplicon Sequencing of Variable 16S rRNA from Bacteria and ITS2 Regions from Fungi and Plants, Reveals Honeybee Susceptibility to Diseases Results from Their Forage Availability under Anthropogenic Landscapes

Pathogens, 2021
European Apis mellifera and Asian Apis cerana honeybees are essential crop pollinators. Microbiome studies can provide complex information on health and fitness of these insects in relation to environmental changes, and plant availability.

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

PeerJ, 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.

Habitat-specific variation in gut microbial communities and pathogen prevalence in bumblebee queens (Bombus terrestris). [PDF]

PLoS ONE, 2018
Gut microbial communities are critical for the health of many insect species. However, little is known about how gut microbial communities respond to anthropogenic changes and how such changes affect host-pathogen interactions.
