Frontiers 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.

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

Local management and landscape effects on diversity of bees, wasps and birds in urban green areas [PDF]
, 2008 Today almost all ecosystems on Earth are directly or indirectly influenced by human activity. Most species occur in ecosystems that are managed by humans and only a small fraction of biodiversity exists in protected areas.

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

Psyche: 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 ...

Investigating Nest Box Utilization by Bumble Bees and Reproductive Development of Male Bumble Bees [PDF]
, 2020 Bumble bees (Bombus Latrielle) are a wide-spread group of pollinating insects that are important species to conserve across many environments to ensure both ecological and economic resiliency because they pollinate important agricultural, horticultural ...

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

Does pathogen spillover from commercially reared bumble bees threaten wild pollinators? [PDF]
PLoS 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]
Science, 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 ...

The Bee Hemolymph Metabolome: A Window into the Impact of Viruses on Bumble Bees [PDF]
Viruses, 2021 State-of-the-art virus detection technology has advanced a lot, yet technology to evaluate the impacts of viruses on bee physiology and health is basically lacking. However, such technology is sorely needed to understand how multi-host viruses can impact the composition of the bee community.
