Prevalence of infection by the microsporidian Nosema spp. in native bumblebees (Bombus spp.) in northern Thailand.

PLoS ONE, 2019
Bumblebees (tribe Bombini, genus Bombus Latreille) play a pivotal role as pollinators in mountain regions for both native plants and for agricultural systems.

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.

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.

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 ...

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 ...

Ultrastructure of Crithidia bombi (Trypanosomatidae) choanomastigotes and haptomorphs with special reference to the flagellar pocket skeleton

Bumblebees are important pollinators of wild plants and crops, and their population declines in the recent years can have detrimental effects on both.

Infection with the trypanosome Crithidia bombi and expression of immune-related genes in the bumblebee Bombus terrestris

, 2010
Social bees and other insects are frequently parasitized by a large range of different microorganisms. Among these is Crithidia bombi (Kinetoplastida: Trypanosomatidae), a common gut parasite of bumblebees, Bombus spp. (Insecta: Apidae).

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 ...

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

F1000Research, 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 ...

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

PLoS 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 ...
