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.

Big bees do a better job : intraspecific size variation influences pollination effectiveness [PDF]

open access: yes, 2014
Funding: School of Biology, University of St AndrewsBumblebees (Bombus spp.) are efficient pollinators of many flowering plants, yet the pollen deposition performance of individual bees has not been investigated.

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

Reproductive Interference in an Introduced Bumblebee: Polyandry may Mitigate Negative Reproductive Impact

open access: yesInsects, 2019
As a signature of reproductive interference (RI), we reviewed hybrid production in eusocial bumblebees in Japan, by comparing introduced Bombus terrestris with native B. ignitus in Honshu (main island of Japan) and with native B.

De Novo Genome Assemblies for Three North American Bumble Bee Species: Bombus bifarius, Bombus vancouverensis, and Bombus vosnesenskii

open access: yesG3: Genes, Genomes, Genetics, 2020
Bumble bees are ecologically and economically important insect pollinators. Three abundant and widespread species in western North America, Bombus bifarius, Bombus vancouverensis, and Bombus vosnesenskii, have been the focus of substantial research ...

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,

Flower Preferences of the Wrocław Botanical Garden Bumblebees (Bombus spp.)

open access: yesJournal of Apicultural Science, 2012
Trzmiele (Bombus spp.) morfologicznie różnią się od siebie długością języczka. W faunie Ogrodu Botanicznego stwierdzono występowanie 7 gatunków trzmieli, a wśród nich długojęzyczkowego Bombus hortorum i średniojęzyczkowego B.

Sex ratio variation in the bumblebee Bombus terrestris [PDF]

open access: yesBehavioral Ecology, 2004
Patterns of sex allocation in bumblebees have been enigmatic and difficult to interpret in either a Fisherian context or in a kinselection perspective. We gathered data on several hundred laboratory-reared colonies of the bumblebee Bombus terrestris and analyzed sex allocation as a function of diapause duration and a series of variables describing ...
