Experimental viral spillover can harm Bombus terrestris workers under field conditions

open access: yesEcological Entomology, 2022
Deformed wing virus (DWV), notorious for its virulence in the western honey bee (Apis mellifera) when vectored by the ectoparasitic mite Varroa destructor, is also widespread among wild bumble bee species, presumably through spillover from honey bees ...

Searching for Molecular Markers to Differentiate Bombus terrestris (Linnaeus) Subspecies in the Iberian Peninsula

open access: yesSociobiology, 2018
Bumblebees (genus Bombus Latreille) are pollinator insects of great ecological and economic importance, which commercial use for pollination has increased since the 80s.

Interspecific Variation in Bumblebee Performance on Pollen Diet: New Insights for Mitigation Strategies. [PDF]

open access: yesPLoS ONE, 2016
Bumblebees (i.e. Bombus genus) are major pollinators of flowering wild plants and crops. Although many species are currently in decline, a number of them remain stable or are even expanding.

Characterizing the Mitogenome of the Endemic Bumblebee Subspecies from the Canary Islands for Conservation Purposes

open access: yesSociobiology, 2021
The taxonomic status of Bombus terrestris subspecies is complex and has deep implications in the management of commercial bumblebees for crop pollination as well as in the establishment of appropriate conservation plans.

The genomes of two key bumblebee species with primitive eusocial organization [PDF]

open access: yes, 2015
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

Review of the methods to determine the hazard and toxicity of pesticides to bumblebees [PDF]

open access: yes, 2001
Methods to determine the impact of pesticides on bumblebees are described. They are classified into laboratory tests to determine the acute toxicity and the hazard to bumblebees, (semi) field tests, and brood tests.

Laboratory phase‐contrast nanotomography of unstained Bombus terrestris compound eyes

open access: yesJournal of Microscopy, 2021
Imaging the visual systems of bumblebees and other pollinating insects may increase understanding of their dependence on specific habitats and how they will be affected by climate change.

Effects of habitat composition and landscape structure on worker foraging distances of five bumblebee species [PDF]

open access: yes, 2016
Bumblebees (Bombus spp.) are important pollinators of both crops and wild flowers. Their contribution to this essential ecosystem service has been threatened over recent decades by changes in land use, which have led to declines in their populations.

Negative Effects of the Neonicotinoid Clothianidin on Foraging Behavior and Antennal Sensitivity in Two Common Pollinator Species, Osmia bicornis and Bombus terrestris

open access: yesFrontiers in Ecology and Evolution, 2021
Insect species richness and abundance has declined rapidly over the last few decades. Various stressors, such as the conversion of natural habitats, climate change, land-use intensification, agrochemicals and pathogens, are thought to be major factors in

Sex ratio variation in the bumblebee Bombus terrestris [PDF]

open access: yesBehavioral Ecology, 2004
Patterns of sex allocation in bumblebees have been enigmatic and difficult to interpret in either a Fisherian context or in a kinselection perspective. We gathered data on several hundred laboratory-reared colonies of the bumblebee Bombus terrestris and analyzed sex allocation as a function of diapause duration and a series of variables describing ...
