The Bumble Bees of Florida, Bombus spp. [PDF]

EDIS, 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.

Olfactory coding in the antennal lobe of the bumble bee Bombus terrestris

Scientific Reports, 2021
Sociality is classified as one of the major transitions in evolution, with the largest number of eusocial species found in the insect order Hymenoptera, including the Apini (honey bees) and the Bombini (bumble bees).

An evidence-based rationale for a North American commercial bumble bee clean stock certification program

Journal of Pollination Ecology, 2023
The commercial production and subsequent movement of bumble bees for pollination of agricultural field and greenhouse crops is a growing industry in North America and globally.

Introduced honey bees increase host plant abundance but decrease native bumble bee species richness and abundance

Ecosphere, 2022
Long‐term variation in the population density of introduced honey bees (Apis mellifera) has been shown to be associated with variations in floral traits in alpine lotus (Saussurea nigrescens).

Earlier Morning Arrival to Pollen-Rewarding Flowers May Enable Feral Bumble Bees to Successfully Compete with Local Bee Species and Expand Their Distribution Range in a Mediterranean Habitat

Insects, 2022
During recent decades, bumble bees (Bombus terrestris) have continuously expanded their range in the Mediterranean climate regions of Israel. To assess their potential effects on local bee communities, we monitored their diurnal and seasonal activity ...

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

PLoS 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.

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

, 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.

Bumble bee forager abundance on lowland heaths is predicated by specific floral availability rather than the presence of honey bee foragers: evidence for forage resource partitioning

Journal of Pollination Ecology, 2018
Honey bees are being scrutinized for their potential impact upon wild bees. In lowland heath mosaics, a simple but resource rich habitat for pollinators, there is a higher probability of niche overlap for bumble bees and honey bees due to the requirement

Decline and Conservation of Bumble Bees [PDF]

Annual Review of Entomology, 2008
Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely ...
