Spanish Journal of Agricultural Research, 2017 Bumblebees provide pollination services not only to wildflowers but also to economically important crops. In the context of the global decline of pollinators, there is an increasing interest in determining the pathogen diversity of bumblebee species.

Unbiased RNA Shotgun Metagenomics in Social and Solitary Wild Bees Detects Associations with Eukaryote Parasites and New Viruses. [PDF]
PLoS ONE, 2016 The diversity of eukaryote organisms and viruses associated with wild bees remains poorly characterized in contrast to the well-documented pathosphere of the western honey bee, Apis mellifera.

Immune gene expression in Bombus terrestris: signatures of infection despite strong variation among populations, colonies, and sister workers. [PDF]
PLoS ONE, 2013 Ecological immunology relies on variation in resistance to parasites. Colonies of the bumblebee Bombus terrestris vary in their susceptibility to the trypanosome gut parasite Crithidia bombi, which reduces colony fitness.

Disentangling the heterogeneity of Crithidia bombi infections in bumblebee populations [PDF]
, 2015 Weltweiter Biodiversitätsverlust und (neu) auftretende Infektionskrankheiten stellen eine ernsthafte Gefahr für Mensch und Umwelt dar und stehen im Fokus derzeitiger Forschungsaktivitäten. Hummeln spielen eine Schlüsselrolle bei der effektiven Bestäubung

Does pathogen spillover from commercially reared bumble bees threaten wild pollinators? [PDF]
PLoS ONE, 2008 The conservation of insect pollinators is drawing attention because of reported declines in bee species and the 'ecosystem services' they provide. This issue has been brought to a head by recent devastating losses of honey bees throughout North America ...

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.

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.

Genetic variation and microbiota in bumble bees cross-infected by different strains of C. bombi
PLoS ONE, 2022 The bumblebee Bombus terrestris is commonly infected by a trypanosomatid gut parasite Crithidia bombi. This system shows a striking degree of genetic specificity where host genotypes are susceptible to different genotypes of parasite.

Poison or Potion: Effects of Sunflower Phenolamides on Bumble Bees and Their Gut Parasite
Biology, 2022 Specific floral resources may help bees to face environmental challenges such as parasite infection, as recently shown for sunflower pollen. Whereas this pollen diet is known to be unsuitable for the larval development of bumble bees, it has been shown ...
