Differences in EAG Response and Behavioral Choices between Honey Bee and Bumble Bee to Tomato Flower Volatiles

open access: yesInsects, 2022
Bumble bees and honey bees are of vital importance for tomato pollination, although honey bees are less attracted to tomato flowers than bumble bees. Little is known about how tomato flower volatile compounds influence the foraging behaviors of honey ...

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.

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.

Cuticular hydrocarbons of alpine bumble bees (Hymenoptera: Bombus) are species-specific, but show little evidence of elevation-related climate adaptation

open access: yesFrontiers in Ecology and Evolution, 2023
Alpine bumble bees are the most important pollinators in temperate mountain ecosystems. Although they are used to encounter small-scale successions of very different climates in the mountains, many species respond sensitively to climatic changes ...

Current Pesticide Risk Assessment Protocols Do Not Adequately Address Differences Between Honey Bees (Apis mellifera) and Bumble Bees (Bombus spp.)

open access: yesFrontiers in Environmental Science, 2016
Recent research has demonstrated colony-level sublethal effects of imidacloprid on bumble bees, affecting foraging and food consumption, and thus colony growth and reproduction, at lower pesticide concentrations than for honey bee colonies.

The Bumble Bees of Florida, Bombus spp.

open access: yesEDIS, 2011
Bumble bees are easily recognized by the corbicula (pollen basket) on the hind tibiae in the females. They are beneficial insects that pollinate many native and ornamental plants.

Flower Color as Predictor for Nectar Reward Quantity in an Alpine Flower Community

open access: yesFrontiers in Ecology and Evolution, 2021
Entomophilous plants have evolved colorful floral displays to attract flower visitors to achieve pollination. Although many insects possess innate preferences for certain colors, the underlying proximate and ultimate causes for this behavior are still ...

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 ...

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 ...

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 ...
