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

open access: yesPLoS 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 ...

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

open access: yesConservation 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.

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

open access: yesPLoS 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.

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

open access: yesEcology 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 ...

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

open access: yesEvolutionary 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 ...

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

open access: yesInsect 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

open access: yesAgricultural 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 ...

Variable effects of nicotine, anabasine, and their interactions on parasitized bumble bees [version 2; referees: 2 approved]

open access: yesF1000Research, 2015
Secondary metabolites in floral nectar have been shown to reduce parasite load in two common bumble bee species. Previous studies on the effects of nectar secondary metabolites on parasitized bees have focused on single compounds in isolation; however ...

Ecological and social factors influence interspecific pathogens occurrence among bees. [PDF]

open access: yesSci Rep
The interspecific transmission of pathogens can occur frequently in the environment. Among wild bees, the main spillover cases are caused by pathogens associated with Apis mellifera, whose colonies can act as reservoirs.

Testing Dose-Dependent Effects of the Nectar Alkaloid Anabasine on Trypanosome Parasite Loads in Adult Bumble Bees.

open access: yesPLoS ONE, 2015
The impact of consuming biologically active compounds is often dose-dependent, where small quantities can be medicinal while larger doses are toxic. The consumption of plant secondary compounds can be toxic to herbivores in large doses, but can also ...
