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.

Do Mimic Hoverflies Spatially Match Their Bumblebee Models? Evidence From a Polymorphic Mimicry System

Ecology and Evolution
Batesian mimicry enables harmless species to evade predation by resembling defended models. Although mimicry theory predicts that mimics should broadly co‐occur with their models, increasing evidence suggests that mimic–model associations may extend ...

On the nomenclature of Bombus flavifrons Smith, 1866 (Hymenoptera, Apidae, Bombini) [PDF]

Journal of Hymenoptera Research
The name Bombus flavifrons has been applied to two different bumble bee species in North America, one described by Ezra Cresson in 1863, the other by Frederick Smith in 1866.

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 ...

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 ...

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.

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.

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.
