Big city Bombus: using natural history and land-use history to find significant environmental drivers in bumble-bee declines in urban development [PDF]

Royal Society Open Science, 2017
Native bee populations are critical sources of pollination. Unfortunately, native bees are declining in abundance and diversity. Much of this decline comes from human land-use change.

De Novo Genome Assemblies for Three North American Bumble Bee Species: Bombus bifarius, Bombus vancouverensis, and Bombus vosnesenskii

G3: Genes, Genomes, Genetics, 2020
Bumble bees are ecologically and economically important insect pollinators. Three abundant and widespread species in western North America, Bombus bifarius, Bombus vancouverensis, and Bombus vosnesenskii, have been the focus of substantial research ...

Validating Morphometrics with DNA Barcoding to Reliably Separate Three Cryptic Species of Bombus Cresson (Hymenoptera: Apidae)

Insects, 2020
Simple Summary Evidence of bumble bee population declines has led to an increase in conservation efforts to protect these important pollinators. However, effective conservation requires accurate species identification.

Insects Associated with Michigan Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]

Great Lakes Entomologist, 2017
(excerpt) Studies of insect associates of bumblebees are not new. For example, Tuck (1896, 1897) reported over 50 species of insects associated with nests of British bumblebees. Sladen (1912) discussed nest associates and parasites of European bumblebees,

Evolution of Phospholipase A2 in Bees and Flies [PDF]

Ecology and Evolution
Phospholipase A2 (PLA2) as a component of venom has been studied intensively in venomous snakes while little has been done in insects. In this study, we firstly identified PLA2 among 36 Hymenoptera (Apis and Bombus genera) and 28 Diptera (Drosophila ...

Tracing ancient viral footprints: a comprehensive study of endogenous viral elements in Bombus species [PDF]

Mobile DNA
Background Endogenous Viral Elements (EVEs) are viral sequences integrated into the host germline and passed to offspring. Most virus types can integrate, often with the help of host retroelements, especially for non-retroviral RNA viruses.

The genetic basis of mimicry in the snowy bumble bee (Bombus niveatus) in Anatolia with insights from a color polymorphic gynandromorph. [PDF]

PLoS Genetics
Bumble bees (Bombus spp.) display remarkable color pattern diversity and convergence driven largely by Müllerian mimicry. In Anatolia, bumble bees mimic each other by converting ancestral yellow anterior setal body color to white in multiple independent ...

Parasites, parasitoids, and hive products that are potentially deleterious to wild and commercially raised bumble bees (Bombus spp.) in North America

Journal of Pollination Ecology, 2023
Bumble bees are important pollinators for a great diversity of wild and cultivated plants, and in many parts of the world certain species have been found to be in decline, gone locally extinct, or even globally extinct.

Revised guidance on the risk assessment of plant protection products on bees (Apis mellifera, Bombus spp. and solitary bees)

EFSA journal. European Food Safety Authority, 2023
The European Commission asked EFSA to revise the risk assessment for honey bees, bumble bees and solitary bees. This guidance document describes how to perform risk assessment for bees from plant protection products, in accordance with Regulation (EU ...

Efecto de la matriz urbana sobre las abejas visitantes florales (Hymenoptera: Apoidea) y la polinización de árboles urbanos en Bogotá, Colombia

Revista Chilena de Entomología, 2022
Resumen. Aunque la urbanización es uno de los mayores impulsores de transformación ecológica a nivel global, su impacto sobre la biodiversidad y procesos ecosistémicos como la polinización ha sido poco estudiado, especialmente en el trópico.
