Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

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

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

Agricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Taxonomic and functional diversity of urban bees of the world

Conservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Bombus terrestris Linnaeus 1758

, 2017
Bombus terrestris (Linnaeus, 1758) Species almost cosmopolitan, with a distribution that extends from northern Europe to north Africa and from central Asia to the Macaronesia, naturally distributed from 0 to 3000 m (Ornosa & Ortiz-Sánchez 2004). It has become increasingly important commercially for its pollination services to agriculture.

Methylation and worker reproduction in the bumble-bee (Bombus terrestris) [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2014
Insects are at the dawn of an epigenetics era. Numerous social insect species have been found to possess a functioning methylation system, previously not thought to exist in insects. Methylation, an epigenetic tag, may be vital for the sociality and division of labour for which social insects are renowned.

The abundance and pollen foraging behaviour of bumble bees in relation to population size of whortleberry (Vaccinium uliginosum). [PDF]

PLoS ONE, 2012
Habitat fragmentation can have severe effects on plant pollinator interactions, for example changing the foraging behaviour of pollinators. To date, the impact of plant population size on pollen collection by pollinators has not yet been investigated ...

BumbleBEEP: A Sensor System for Bumblebee Colony Monitoring

Entomologia Experimentalis et Applicata, EarlyView.
We present a bumblebee colony monitoring system, BumbleBEEP. The system is fitted with thermometers and a custom weight sensor. These record data up to every 15 min, recording bumblebee brood nest temperature, environmental ambient temperature, and colony growth.

RNA editing is abundant and correlates with task performance in a social bumblebee

Nature Communications, 2019
Bumblebee workers are genetically highly similar but they show different behaviors such as brood care and foraging. Here the authors report a high level of ADAR-mediated RNA editing in the bumblebee Bombus terrestris and its weak correlation to task ...

Urban habitat fragmentation and floral resources shape the occurrence of gut parasites in two bumblebee species

Ecology and Evolution, 2023
Urbanization and the expansion of human activities foster radical ecosystem changes with cascading effects also involving host‐pathogen interactions. Urban pollinator insects face several stressors related to landscape and local scale features such as ...
