Regular periods of abdominal contractions recorded from larvae of the bumblebee, Bombus terrestris (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2006
Using an opto-cardiograph combined with an infrared gas analyzer regular bouts of abdominal contractions were recorded from last instar larva of Bombus terrestris. The rate of CO2 release was about 0.7 ml g-1 h-1.

Do bumblebees have signatures? Demonstrating the existence of a speed-curvature power law in Bombus terrestris locomotion patterns.

open access: yesPLoS ONE, 2020
We report the discovery that Bombus terrestris audax (Buff-tailed bumblebee) locomotor trajectories adhere to a speed-curvature power law relationship which has previously been found in humans, non-human primates and Drosophila larval trajectories.

Rearing of Native Bumblebee Species Bombus haemorrhoidalis for Greenhouse Pollination in Pakistan

open access: yesAgriculture
Greenhouse tomato production is a growing business worldwide, and it is strongly promoted by bumblebee pollination. Although there are over 250 bumblebee species worldwide, very few species have been reared successfully for greenhouse tomato pollination.

Allele specific expression and methylation in the bumblebee, Bombus terrestris

open access: yesPeerJ, 2015
ABSTRACT The social hymenoptera are emerging as models for epigenetics. DNA methylation, the addition of a methyl group, is a common epigenetic marker. In mammals and flowering plants methylation affects allele specific expression.

Colour pattern and DNA-barcoding reveal a wide distribution of the insular endemic bumble bee Bombus xanthopus in the Tuscan Archipelago

open access: yesThe European Zoological Journal
Insular ecosystems, due to their isolation from the mainland and limited areas, are often endemism hotspots. However, the same factors that drive high endemicity also make islands vulnerable to anthropogenic pressure and thus to biodiversity loss.

Buzzing benefits: How multi-species pollination boosts strawberry yield, quality, and nutritional value

open access: yesJournal of Pollination Ecology
A diverse assemblage of insect visitors can provide functional complementarity within plant pollination due to differences in characteristics such as their physical traits, visitation rate and foraging time of day or year.

Identification of cryptic species Bombus lucorum-complex and Bombus terrestris in Penza region using the PCR–RFLP method

open access: yesИзвестия высших учебных заведений. Поволжский регион: Естественные науки
Background. Studying the distribution of cryptic species Bombus lucorum-complex is one of the most difficult tasks in regional entomological research. In Penza region there is information about only two species of bumblebees B. terrestris and B. lucorum,

High-Res Acoustic and Environmental Data to Monitor Bombus dahlbomii Amid Invasive Species, Habitat Loss

open access: yesScientific Data
The decline of the endemic Patagonian bumblebee (Bombus dahlbomii) as a result of invasive species and habitat loss, among other stressors, has raised significant conservation concerns for the species and the ecosystem it inhabits.
