The bumblebee Bombus terrestris carries a primary inoculum of Tomato brown rugose fruit virus contributing to disease spread in tomatoes.

PLoS ONE, 2019
The bumblebee Bombus terrestris is a beneficial pollinator extensively used in tomato production. Our hypothesis was that bumblebee hives collected from a Tomato brown rugose fruit virus (ToBRFV) infected tomato greenhouse, preserve an infectious primary

Parasites of the genus Nosema, Crithidia and Lotmaria in the honeybee and bumblebee populations: a case study in India

Вавиловский журнал генетики и селекции, 2018
The populations of honeybees and bumblebees have been decreasing around the world in the recent decades. A variety of pathogens and parasites, including  bacteria, fungi, protozoa, nematodes, mites and insects play signi ficant role in honeybee and ...

Lipolytic Activity of a Carboxylesterase from Bumblebee (Bombus ignitus) Venom

Toxins, 2021
Bee venom is a complex mixture composed of peptides, proteins with enzymatic properties, and low-molecular-weight compounds. Although the carboxylesterase in bee venom has been identified as an allergen, the enzyme’s role as a venom component has not ...

Exact modifications on a vacuum spacetime due to a gradient bumblebee field at its vacuum expectation value

European Physical Journal C: Particles and Fields, 2022
This work belongs to the context of the standard-model extension, in which a Lorentz symmetry violation is induced by a bumblebee field as it acquires a nonzero vacuum expectation value.

Super-entropy bumblebee AdS black holes

Physics Letters B
Motivated by the effect of the bumblebee field on thermodynamic instability in (non)extended phase space, we study the thermodynamic instability for the bumblebee AdS black holes. For this purpose, first, we evaluate the effect of the bumblebee field (or

Substantial variability in morphological scaling among bumblebee colonies

Royal Society Open Science, 2022
Differences in organ scaling among individuals may play an important role in determining behavioural variation. In social insects, there are well-documented intraspecific differences in colony behaviour, but the extent that organ scaling differs within ...

A Sublethal Concentration of Sulfoxaflor Has Minimal Impact on Buff-Tailed Bumblebee (Bombus terrestris) Locomotor Behaviour under Aversive Conditioning

Toxics, 2023
Pesticide exposure has been cited as a key threat to insect pollinators. Notably, a diverse range of potential sublethal effects have been reported in bee species, with a particular focus on effects due to exposure to neonicotinoid insecticides.

Bumblebee Abundance in Species-Rich Grasslands in Southern Sweden Decreases with Increasing Amount of Arable Land at a Landscape Level

Insects
Conservation of bumblebee populations is essential because of their role as pollinators. Declines in bumblebee abundance have been documented in recent decades, mostly attributed to agricultural intensification, landscape simplification and loss of semi ...

Identification of fungi isolated from commercial bumblebee colonies [PDF]

PeerJ
Fungi can have important beneficial and detrimental effects on animals, yet our understanding of the diversity and function of most bee-associated fungi is poor.
