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

Honey bees exhibit greater patch fidelity than bumble bees when foraging in a common environment

open access: yesEcosphere, 2023
Animals commonly exhibit a tendency to return to previously visited locations. Such tendency is manifested at different scales, for example, fidelity to a site or fidelity to a specific patch within a site.

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 ...

Does pathogen spillover from commercially reared bumble bees threaten wild pollinators? [PDF]

open access: yesPLoS ONE, 2008
The conservation of insect pollinators is drawing attention because of reported declines in bee species and the 'ecosystem services' they provide. This issue has been brought to a head by recent devastating losses of honey bees throughout North America ...

Bumble bees create a buzz [PDF]

open access: yesScience, 2017
Conservation Foraging bees create characteristic vibrations at frequencies of 120 to 400 Hz. Miller-Struttmann et al. set out to investigate whether the vibrations created by bumble bees can be used to estimate pollination success. They show that physical attributes such as body size and tongue length, which influence pollination success, are ...

Radar tracking and motion-sensitive cameras on flowers reveal the development of pollinator multi-destination routes over large spatial scales [PDF]

open access: yes, 2012
Central place foragers, such as pollinating bees, typically develop circuits (traplines) to visit multiple foraging sites in a manner that minimizes overall travel distance.

Morphological characterization and staging of bumble bee pupae [PDF]

open access: yesPeerJ, 2018
Bumble bees (Hymenoptera: Apidae, Bombus) are important pollinators and models for studying mechanisms underlying developmental plasticity, such as factors influencing size, immunity, and social behaviors. Research on such processes, as well as expanding

First detection of the larval chalkbrood disease pathogen Ascosphaera apis (Ascomycota: Eurotiomycetes: Ascosphaerales) in adult bumble bees. [PDF]

open access: yesPLoS ONE, 2015
Fungi in the genus Ascosphaera (Ascomycota: Eurotiomycetes: Ascosphaerales) cause chalkbrood disease in larvae of bees. Here, we report the first-ever detection of the fungus in adult bumble bees that were raised in captivity for studies on colony ...
