Assessing pathogen risk for wild bumblebees (Bombus spp., Apidae) in Canada

Conservation Science and Practice, Volume 7, Issue 8, August 2025.
Pathogen spillover poses a significant threat to wild bumble bees (Bombus spp.) in Canada. Our study maps areas of overlap between high conservation priority regions for bumble bees and regions of pathogen spillover risk from managed bees, incorporating uncertainty in pathogen prevalence.

Differential gene expression and alternative splicing in insect immune specificity [PDF]

, 2004
Background: Ecological studies routinely show genotype-genotype interactions between insects and their parasites. The mechanisms behind these interactions are not clearly understood.

Comprehensive bee pathogen screening in Belgium reveals Crithidia mellificae as a new contributory factor to winter mortality. [PDF]

PLoS ONE, 2013
Since the last decade, unusually high honey bee colony losses have been reported mainly in North-America and Europe. Here, we report on a comprehensive bee pathogen screening in Belgium covering 363 bee colonies that were screened for 18 known disease ...

Landscape‐Wide Metabarcoding Shows Interactions Among the Gut Microbiome and Pollen Diversity in the Invasive Bumblebee, Bombus terrestris

Ecology and Evolution, Volume 15, Issue 7, July 2025.
The study examines how environmental factors and dietary diversity influence the gut microbiome of the invasive European buff‐tailed bumblebee (Bombus terrestris) in Tasmania. We found that gut bacterial composition and diversity were significantly affected by annual precipitation, pasture percentage, temperature and interactions between pollen ...

Effects of natal and novel Crithidia bombi (Trypanosomatidae) infections on Bombus terrestris hosts [PDF]

, 2018
.: Bombus terrestris queens may contract infections of the trypanosome parasite Crithidia bombi from their natal nests; alternatively, the queens may also become infected after leaving their natal nests while foraging on contaminated flowers. We expected

The genotypic structure of a multi-host bumblebee parasite suggests a role for ecological niche overlap. [PDF]

PLoS ONE, 2011
The genotypic structure of parasite populations is an important determinant of ecological and evolutionary dynamics of host-parasite interactions with consequences for pest management and disease control.

Microbial Evolution in Allodapine Bees: Perspectives From Trophallactic, Socially Plastic Pollinators

Evolutionary Applications, Volume 18, Issue 7, July 2025.
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 ...

Heather nectar extracts reduce within-colony epidemics of the bumblebee parasite Crithidia bombi

Disease and habitat loss are significant causes of pollinator declines, and evidence indicates the two are linked. In Britain, lowland heath is an important bee habitat, but over 80% has been lost since the 1800s.

Answering key bumble bee conservation questions by studying discovered wild nests: A Bombus affinis case study

Insect Conservation and Diversity, Volume 18, Issue 3, Page 303-318, May 2025.
The information learned from discovered wild bumble bee nests can be of great conservation value if studied in situ and post‐season excavation in a standardised way. We provide standardised guidance to follow when nest discoveries arise, including key conservation questions and methodological guidelines to study behaviour, floral use, genetics, body ...

The smell of infection: Disease surveillance in insects using volatile organic compounds

Agricultural and Forest Entomology, Volume 27, Issue 1, Page 81-89, February 2025.
Abstract Insects play crucial roles in nearly every ecosystem and provide a wide array of ecosystem services. However, both managed and wild insect populations face threats from parasites and pathogens, which require surveillance to mitigate. Current infectious disease surveillance methods for insects often involve invasive, time‐consuming and ...
