Endosymbionts that threaten commercially raised and wild bumble bees (Bombus spp.)

open access: yesJournal of Pollination Ecology, 2023
Bumble bees (Bombus spp.) are important pollinators for both wild and agriculturally managed plants. We give an overview of what is known about the diverse community of internal potentially deleterious bumble bee symbionts, including viruses, bacteria ...

Honey bee-collected pollen is a potential source of Ascosphaera apis infection in managed bumble bees [PDF]

open access: yesScientific Reports, 2019
The trade of bumble bees started in the early nineties for pollinator-dependent greenhouse plants. Nowadays, its rearing and transport have received public attention, since managed bees can transfer pathogens to wild bee populations.

Pesticide use negatively affects bumble bees across European landscapes

open access: yesNature, 2023
Sustainable agriculture requires balancing crop yields with the effects of pesticides on non-target organisms, such as bees and other crop pollinators. Field studies demonstrated that agricultural use of neonicotinoid insecticides can negatively affect ...

The effects of glyphosate, pure or in herbicide formulation, on bumble bees and their gut microbial communities

open access: yesScience of the Total Environment, 2023
The widespread use of glyphosate-based formulations to eliminate unwanted vegetation has increased concerns regarding their effects on non-target organisms, such as honey bees and their gut microbiota.

Sperm can't take the heat: short-term temperature exposures compromise fertility of male bumble bees (Bombus impatiens).

open access: yesJournal of insect physiology, 2023
Bumble bee (genus Bombus) populations are increasingly under threat from habitat fragmentation, pesticides, pathogens, and climate change. Climate change is likely a prime driver of bumble bee declines but the mechanisms by which changing climates alter ...

Honey bees and bumble bees may be exposed to pesticides differently when foraging on agricultural areas.

open access: yesScience of the Total Environment, 2023
In an agricultural environment, where crops are treated with pesticides, bees are likely to be exposed to a range of chemical compounds in a variety of ways.

High thermal tolerance in high‐elevation species and laboratory‐reared colonies of tropical bumble bees

open access: yesEcology and Evolution, 2022
Bumble bees are key pollinators with some species reared in captivity at a commercial scale, but with significant evidence of population declines and with alarming predictions of substantial impacts under climate change scenarios.

Carpenter Bees (Xylocopa) Harbor a Distinctive Gut Microbiome Related to That of Honey Bees and Bumble Bees

open access: yesApplied and Environmental Microbiology, 2022
Gut microbiomes from social bees, such as honey bees and bumble bees, are conserved and consist of host-restricted bacteria that are transmitted among sterile female workers within a colony and that are important to the health of these key insect ...

Drought-induced reduction in flower size and abundance correlates with reduced flower visits by bumble bees

open access: yesAoB Plants, 2021
Reduced water availability can cause physiological stress in plants that affects floral development leading to changes in floral morphology and traits that mediate interactions with pollinators.

Contrasting patterns of richness, abundance, and turnover in mountain bumble bees and their floral hosts.

open access: yesEcology, 2022
Environmental gradients generate and maintain biodiversity on Earth. Mountain slopes are among the most pronounced terrestrial environmental gradients, and the elevational structure of species and their interactions can provide unique insight into the ...
