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.

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.

Foraging preferences of bumble bee castes are weakly related to plant species cover on two arable agri-environment habitat types

Journal of Pollination Ecology, 2023
Arable field margins provide important floral resources for insect foragers. This study assessed the significance of cultivated margins and floristically enhanced margins, both English agri-environment scheme (AES) options, to foraging bumble bees ...

The potential of electricity transmission corridors in forested areas as bumblebee habitat [PDF]

Royal Society Open Science, 2016
Declines in pollinator abundance and diversity are not only a conservation issue, but also a threat to crop pollination. Maintained infrastructure corridors, such as those containing electricity transmission lines, are potentially important wild ...

Pollinator Visitation Alters Cranberry Flower Fungal Communities in Wisconsin Cranberry Agroecosystems. [PDF]

Environ Microbiol Rep
A two‐year study reveals shared fungal communities between cranberry flowers and insect visitors, including Apis mellifera, Bombus species, solitary bees and hover flies. Greater fungal richness was present in pollinator‐accessible flowers compared to those that were tented.
