Genetic Variability of the Neogregarine Apicystis bombi, an Etiological Agent of an Emergent Bumblebee Disease [PDF]

open access: yesPLoS 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

Resistance and Tolerance to Imperfectly Specialized Parasites: Milkweed Butterflies and Their Protozoan Parasites [PDF]

open access: yesEcology and Evolution
Understanding 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 ...

Detection of Apicystis bombi (Apicomplexa: Neogregarinorida) in carpenter bees of Argentina [PDF]

open access: yesInternational 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

Morphological characteristics of local entomopathogenic protozoan strains isolated from insect cadavers of certain stored-grain pests in Egypt

open access: yesEgyptian Journal of Biological Pest Control, 2020
The present study has documented, for the first time in Egypt, the natural occurrence of four entomopathogenic protozoans (EPP) among five of the most abundant and damaging insect pests of stored grains or their products. These insect pests (Laemophloeus

Functional traits linked to pathogen prevalence in wild bee communities [PDF]

open access: yesScientific 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]

open access: yesPathogens, 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.

Study of the Metatranscriptome of Eight Social and Solitary Wild Bee Species Reveals Novel Viruses and Bee Parasites [PDF]

open access: yesFrontiers 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]

open access: yesInsects, 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

Assessment of intestinal parasites in the coexisting Bombus terrestris (Apidae) and Xylocopa augusti (Apidae) in central Chile

open access: yesRevista Chilena de Historia Natural, 2020
Bombus terrestris is a European bumblebee extensively commercialized worldwide for crop pollination. In Chile, this species was introduced in 1997 and after confinement escape, it has spread and established in several localities of central-southern Chile
