Visitation frequencies of bumblebees and swallowtail butterflies to flowers and the nectar sugar concentration of Rhododendron kaempferi and R. japonicum in mountains of central Japan

Journal of Pollination Ecology, 2017
Relationships between flower visitor composition and floral traits help us to understand floral evolution. Swallowtail butterflies have been assumed to be the main pollinators of Rhododendron kaempferi and R. japonicum based on their floral shapes, and R.

Foraging Bumblebees Selectively Attend to Other Types of Bees Based on Their Reward-Predictive Value

Insects, 2020
Using social information can be an efficient strategy for learning in a new environment while reducing the risks associated with trial-and-error learning. Whereas social information from conspecifics has long been assumed to be preferentially attended by

Observations on Colony Size in Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]

, 2017
(excerpt) One factor to consider when attempting to rear bumblebees (Bombus spp.) for pollination of crops is potential colony size. Species which emerge from hibernation early and continue to produce workers late in the summer or early fall are likely ...

Characteristics of the tomato fruit (Solanum lycopersicum) using native bumblebees (Bombus atratus) as pollinators in greenhouse

Agrociencia, 2020
In Uruguay, the production of tomato (Solanum lycopersicum) in greenhouse presents pollination issues that limit its yield. The use of bumblebees (Bombus spp.) as pollinators can help overcome this problem as they perform “buzzing pollination”, a ...

Bumblebees perceive the spatial layout of their environment in relation to their body size and form to minimize inflight collisions

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Like many other animals, including humans, insects frequently move through densely cluttered environments to perform activities critical for their survival, such as foraging.

Dominance of Fructose-Associated Fructobacillus in the Gut Microbiome of Bumblebees (Bombus terrestris) Inhabiting Natural Forest Meadows

Insects, 2022
Bumblebees are key pollinators in agricultural landscapes. However, little is known about how gut microbial communities respond to anthropogenic changes. We used commercially produced colonies of buff-tailed bumblebees (Bombus terrestris) placed in three

Knock‐on community impacts of a novel vector: spillover of emerging DWV‐B from Varroa‐infested honeybees to wild bumblebees

Ecology Letters, 2019
Novel transmission routes can directly impact the evolutionary ecology of infectious diseases, with potentially dramatic effect on host populations and knock‐on effects on the wider host community.

The genomes of two key bumblebee species with primitive eusocial organization [PDF]

, 2015
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

Temperature and livestock grazing trigger transcriptome responses in bumblebees along an elevational gradient

iScience, 2022
Summary: Climate and land-use changes cause increasing stress to pollinators but the molecular pathways underlying stress responses are poorly understood.
