Does the waggle dance help honey bees to forage at greater distances than expected for their body size? [PDF]

open access: yes, 2015
A honey bee colony has been likened to an oil company. Some members of the company or colony prospect for valuable liquid resources. When these are discovered other group members can be recruited to exploit the resource. The recruitment of nestmates to a

Convergent Loss of Prothoracicotropic Hormone, A Canonical Regulator of Development, in Social Bee Evolution

open access: yesFrontiers in Physiology, 2022
The evolution of insect sociality has repeatedly involved changes in developmental events and their timing. Here, we propose the hypothesis that loss of a canonical regulator of moulting and metamorphosis, prothoracicotropic hormone (PTTH), and its ...

Functional resin use in solitary bees [PDF]

open access: yesEcological Entomology, 2021
1. Overall, more than 30% of bee species depend on non‐floral resources, such as resin. However, the importance of resin in bee ecology, particularly for solitary bees, has received very little attention thus far. 2. A plethora of loose natural history observations, inferences, and author opinions hint towards a striking range of uses

Unbiased RNA shotgun metagenomics in social and solitary wild bees detects associations with eukaryote parasites and new viruses [PDF]

open access: yes, 2016
The diversity of eukaryote organisms and viruses associated with wild bees remains poorly characterized in contrast to the well-documented pathosphere of the western honey bee, Apis mellifera.

Calcareous grassland fragments as sources of bee pollinators for the surrounding agricultural landscape

open access: yesGlobal Ecology and Conservation, 2021
In Central Europe, agricultural intensification has led to increasing fragmentation and loss of semi-natural habitats. In turn, ecosystem services such as pollination are being lost when insect pollinators depend on semi-natural habitats.

Limited social plasticity in the socially polymorphic sweat bee Lasioglossum calceatum [PDF]

open access: yes, 2018
This is the final version of the article. Available from the publisher via the DOI in this record.Eusociality is characterised by a reproductive division of labour, where some individuals forgo direct reproduction to instead help raise kin.

Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

open access: yes, 2015
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

Survival rate and changes in foraging performances of solitary bees exposed to a novel insecticide

open access: yesEcotoxicology and Environmental Safety, 2021
Solitary bees are among the most important pollinators worldwide however population declines especially in croplands has been noticed. The novel pesticide sulfoxaflor is a competitive modulator of nicotinic acetylcholine receptors (nAChR) in insects ...

Scientific Opinion on the science behind the development of a risk assessment of Plant Protection Products on bees (Apis mellifera, Bombus spp. and solitary bees)

open access: yesEFSA Journal, 2012
The PPR Panel was asked to deliver a scientific opinion on the science behind the development of a risk assessment of plant protection products on bees (Apis mellifera, Bombus spp. and solitary bees).

Numerical cognition in bees and other insects [PDF]

open access: yes, 2016
The ability to perceive the number of objects has been known to exist in vertebrates for a few decades, but recent behavioral investigations have demonstrated that several invertebrate species can also be placed on the continuum of numerical abilities ...
