Bumblebees [PDF]

, 2010
Since bumblebees are a group associated with cool climates, Britain supports a large proportion (~10%) of the world's bumblebee fauna. However, three of our 25 species have become extinct, and seven species are Biodiversity Action Plan (BAP) listed, a ...

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

Higher Essential Amino Acid and Crude Protein Contents in Pollen Accelerate the Oviposition and Colony Foundation of Bombus breviceps (Hymenoptera: Apidae)

Insects, 2023
Pollen is an important source of nutrition for bumblebees to survive, reproduce, and raise their offspring. To explore the nutritional requirements for the egg laying and hatching of queenright Bombus breviceps colonies, camellia pollen, oilseed rape ...

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.

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 ...

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

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.

Bumblebees can detect floral humidity [PDF]

, 2021
Floral humidity, a region of elevated humidity proximal to the flower, occurs in many plant species and may add to their multimodal floral displays. So far, the ability to detect and respond to floral humidity cues has been only established for hawkmoths
