Reduced nest development of reared Bombus terrestris within apiary dense human-modified landscapes

open access: yesScientific Reports, 2021
Wild bees are in decline on a local to global scale. The presence of managed honey bees can lead to competition for resources with wild bee species, which has not been investigated so far for human-modified landscapes.

Infection and transmission of Nosema bombi in Bombus terrestris colonies and its effect on hibernation, mating and colony founding [PDF]

open access: yes, 2008
The impact of the microsporidium Nosema bombi on Bombus terrestris was studied by recording mating, hibernation success, protein titre in haemolymph, weight change during hibernation, and colony founding of queens that were inoculated with N.

Urbanization is associated with shifts in bumblebee body size, with cascading effects on pollination

open access: yesEvolutionary Applications, 2021
Urbanization is a global phenomenon with major effects on species, the structure of community functional traits and ecological interactions. Body size is a key species trait linked to metabolism, life‐history and dispersal as well as a major determinant ...

Observations on Colony Size in Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]

open access: yes, 2017
(excerpt) One factor to consider when attempting to rear bumblebees (Bombus spp.) for pollination of crops is potential colony size. Species which emerge from hibernation early and continue to produce workers late in the summer or early fall are likely ...

BumbleKey: an interactive key for the identification of bumblebees of Italy and Corsica (Hymenoptera, Apidae) [PDF]

open access: yes, 2018
BumbleKey is a matrix-based, interactive key to all 45 species of bumblebees of Italy and Corsica. The key allows to identify adult males and females (queens and workers) using morphological characters. The key is published online, open-access, at http://

Effects of Heat Stress on Mating Behavior and Colony Development in Bombus terrestris (Hymenoptera: Apidae)

open access: yesFrontiers in Ecology and Evolution, 2021
Climate change is related to an increase in the frequency and intensity of extreme events such as heatwaves. In insect pollinators, heat exposure is associated with direct physiological perturbations, and in several species, could lead to a decrease of ...

A Test of Bombus terrestris Cocoon and other Common Methods for Nest Initiation in B. lapidarius and B. hortorum

open access: yesJournal of Apicultural Science, 2012
Porównano kilka metod stymulacji zakładania gniazd (ze szczególnym uwzględnieniem wykorzystania kokonów Bombus terrestris) przez matki B. lapidarius i B. hortorum. Stwierdzono, że procent matek B. lapidarius, które wybudowały pierwszą miseczkę na jaja na

Consequences of the high abundance of Bombus terrestris on the pollination of Vicia faba

open access: yesJournal of Pollination Ecology, 2021
One of the main visitors to Fabia bean crops (Vicia faba) in South America is the invasive bumblebee species Bombus terrestris. This is particularly true in Chile, where B.

Queen control of a key life-history event in a eusocial insect [PDF]

open access: yes, 2013
In eusocial insects, inclusive fitness theory predicts potential queen–worker conflict over the timing of events in colony life history. Whether queens or workers control the timing of these events is poorly understood.
