Bumble bees in landscapes with abundant floral resources have lower pathogen loads
Scientific Reports, 2020 The pollination services provided by bees are essential for supporting natural and agricultural ecosystems. However, bee population declines have been documented across the world.

Scientific Reports, 2020 Deformed wing virus (DWV) is a persistent pathogen of European honey bees and the major contributor to overwintering colony losses. The prevalence of DWV in honey bees has led to significant concerns about spillover of the virus to other pollinating ...

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 ...

Infection and transmission of Nosema bombi in Bombus terrestris colonies and its effect on hibernation, mating and colony founding [PDF]
, 2008 The impact of the microsporidium Nosema bombi on Bombus terrestris was studied by recording mating, hibernation success, protein titre in haemolymph, weight change during hibernation, and colony founding of queens that were inoculated with N.

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 ...

bioRxiv, 2020 Bumble bees (Bombus spp.) are important and widespread insect pollinators, but the act of foraging on flowers can expose them to harmful pesticides and environmental chemicals such as oxidizers and heavy metals. How these compounds directly influence bee

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

Analyzing the Dietary Diary of Bumble Bee [PDF]
Frontiers in Plant Science, 2020 Bumble bees are important crop pollinators and provide important pollination services to their respective ecosystems. Their pollen diet and thus food preferences can be characterized through nucleic acid sequence analysis. We present ITS2 amplicon sequence data from pollen collected by bumble bees. The pollen was collected from six different bumble bee

Morphological characterization and staging of bumble bee pupae [PDF]
PeerJ, 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

Molecular Ecology, 2020 Worldwide pollinator declines lead to pollination deficits in crops and wild plants, and managed bees are frequently used to meet the increasing demand for pollination. However, their foraging can be affected by flower availability and colony size.
