Resistance and Tolerance to Imperfectly Specialized Parasites: Milkweed Butterflies and Their Protozoan Parasites [PDF]
Ecology and EvolutionUnderstanding host specificity and cross‐species transmission of parasites is crucial for predicting the risk and consequences of parasite spillover. We experimentally examined these dynamics in two closely related, sympatric, milkweed butterfly hosts ...

Genetic Variability of the Neogregarine Apicystis bombi, an Etiological Agent of an Emergent Bumblebee Disease [PDF]
PLoS ONE, 2013 The worldwide spread of diseases is considered a major threat to biodiversity and a possible driver of the decline of pollinator populations, particularly when novel species or strains of parasites emerge. Previous studies have suggested that populations

Detection of Apicystis bombi (Apicomplexa: Neogregarinorida) in carpenter bees of Argentina [PDF]
International Journal for Parasitology: Parasites and Wildlife, 2023 Historically, the neogregarine Apicystis bombi was isolated almost exclusively from bumble bees (Bombus spp.) where it disrupts adipose tissue, increasing hosts’ mortality rates. Records in solitary bees are scarce worldwide. To check for its presence in

Functional traits linked to pathogen prevalence in wild bee communities [PDF]
Scientific Reports, 2021 Reports of pollinator declines have prompted efforts to understand contributing factors and protect vulnerable species. While pathogens can be widespread in bee communities, less is known about factors shaping pathogen prevalence among species ...

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 [PDF]
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.

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 ...

Study of the Metatranscriptome of Eight Social and Solitary Wild Bee Species Reveals Novel Viruses and Bee Parasites [PDF]
Frontiers in Microbiology, 2018 Bees are associated with a remarkable diversity of microorganisms, including unicellular parasites, bacteria, fungi, and viruses. The application of next-generation sequencing approaches enables the identification of this rich species composition as well

Genetic Factors and Host Traits Predict Spore Morphology for a Butterfly Pathogen [PDF]
Insects, 2013 Monarch butterflies (Danaus plexippus) throughout the world are commonly infected by the specialist pathogen Ophryocystis elektroscirrha (OE). This protozoan is transmitted when larvae ingest infectious stages (spores) scattered onto host plant leaves by

Urbanization Shifts Immunometabolism in a Common Bumblebee. [PDF]
Ecol EvolCities provide contrasting habitats for pollinators and it proves difficult to predict the overall effect of urban living on the health of wild bees. By combining measurements of local competition, pathogen pressures, and exposure to pollutants along an urbanization gradient, we evidenced an upregulation of genes involved in immunometabolism in bees ...

Lactic acid bacteria in Swedish honey bees during outbreaks of American foulbrood. [PDF]
Ecol EvolTo investigate if the bacterial disease American foulbrood (AFB) affects lactic acid bacteria (LAB) in honeybees, adult bees were collected from colonies with and without AFB during outbreaks in Sweden. We found differences in the abundance of the individual LAB between the different outbreaks.
