Bumble Bee Foraged Pollen Analyses in Spring Time in Southern Estonia Shows Abundant Food Sources

open access: yesInsects, 2021
Agricultural landscapes usually provide higher quantities of single-source food, which are noticeably lacking in diversity and might thus have low nutrient value for bumble bee colony development.

Endosymbionts that threaten commercially raised and wild bumble bees (Bombus spp.)

open access: yesJournal of Pollination Ecology, 2023
Bumble bees (Bombus spp.) are important pollinators for both wild and agriculturally managed plants. We give an overview of what is known about the diverse community of internal potentially deleterious bumble bee symbionts, including viruses, bacteria ...

Linking bacterial diversity to floral identity in the bumble bee pollen basket

open access: yesEnvironmental DNA, 2021
Multitrophic interactions are ubiquitous in nature and form the basis of biodiversity. For example, bumble bees visit flowers to collect pollen, on which a variety of bacteria exist.

The Potential Influence of Bumble Bee Visitation on Foraging Behaviors and Assemblages of Honey Bees on Squash Flowers in Highland Agricultural Ecosystems. [PDF]

open access: yesPLoS ONE, 2016
Bee species interactions can benefit plant pollination through synergistic effects and complementary effects, or can be of detriment to plant pollination through competition effects by reducing visitation by effective pollinators.

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.

Abundance and Diversity of Native Bumble Bees Associated with Agricultural Crops: The Willamette Valley Experience

open access: yesPsyche: A Journal of Entomology, 2010
There are widespread concerns about declining populations of bumble bees due to conversion of native habitats to agroecosystems. Certain cropping systems, however, provide enormous foraging resources, and are beneficial for population build up of native ...

Pollen samples from a bumble bee (Hymenoptera: Apidae) collection show historic foraging on introduced and native plants in the South Island of New Zealand.

open access: yesPLoS ONE, 2022
Historic pollination networks are important to understand interactions between different plant and pollinator species, as well as to differentiate between causes and consequences of present insect population decline.

The adaptive significance of sensory bias in a foraging context: floral colour preferences in the bumblebee Bombus terrestris [PDF]

open access: yes, 2007
Innate sensory biases could play an important role in helping naïve animals to find food. As inexperienced bees are known to have strong innate colour biases we investigated whether bumblebee (Bombus terrestris) colonies with stronger biases for the most

Strong Interspecific Differences in Foraging Activity Observed Between Honey Bees and Bumble Bees Using Miniaturized Radio Frequency Identification (RFID)

open access: yesFrontiers in Ecology and Evolution, 2018
Central place foragers depart from and return to a central location with enough resources for themselves, and in many cases, for the group. Honey bees and bumble bees are eusocial central place foragers.

Pollinators on the polar edge of the Ecumene: taxonomy, phylogeography, and ecology of bumble bees from Novaya Zemlya [PDF]

open access: yesZooKeys, 2019
The High Arctic bumble bee fauna is rather poorly known, while a growing body of recent molecular research indicates that several Arctic species may represent endemic lineages with restricted ranges.
