Photoreceptor processing speed and input resistance changes during light adaptation correlate with spectral class in the bumblebee, Bombus impatiens. [PDF]

open access: yes, 2011
Colour vision depends on comparison of signals from photoreceptors with different spectral sensitivities. However, response properties of photoreceptor cells may differ in ways other than spectral tuning. In insects, for example, broadband photoreceptors,

La importancia del color: morfos florales, tasas de visita y éxito reproductivo en el arbusto Sarothamnus scoparius

open access: yesEcología Austral, 2015
El estudio de la variación intraespecífica del color de las flores nos permite comprender mejor el papel de los polinizadores como agentes de selección, y su efecto sobre la abundancia de las variantes florales.

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

open access: yesPLoS 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 ...

Photoreceptor spectral sensitivity in the bumblebee, Bombus impatiens (Hymenoptera: Apidae). [PDF]

open access: yes, 2010
The bumblebee Bombus impatiens is increasingly used as a model in comparative studies of colour vision, or in behavioural studies relying on perceptual discrimination of colour.

Potential application of the bumblebee foraging recruitment pheromone for commercial greenhouse pollination [PDF]

open access: yes, 2009
Commercial bumblebee colonies are important crop pollinators. Here we assess whether application of artificial foraging recruitment pheromone can increase foraging activity in Bombus terrestris colonies on a relevant timescale for commercial pollination.

Long-term changes in the composition and distribution of the Hungarian bumble bee fauna (Hymenoptera, Apidae, Bombus) [PDF]

open access: yesJournal of Hymenoptera Research, 2023
One of the most important pollinator taxa is Bombus (Hymenoptera, Apidae), the genus of bumble bees, since they are important, often specialized, pollinators of many plants.

A failed invasion? Commercially introduced pollinators in Southern France [PDF]

open access: yes, 2009
The natural diversity of Bombus terrestris subspecies could be under threat from the commercialisation of bumblebees. Therefore, to determine whether commercially imported bumblebees are able to establish and spread, we carried out

The complete mitochondrial genome of Bombus filchnerae (Hymenoptera: Apidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2021
Here, we report the complete mitochondrial genome (mitogenome) of Bombus filchnerae (Hymenoptera: Apidae). The genome size of B. filchnerae was 18,553 bp with 88.7% A + T content, containing 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes ...
