Host Detection by Cuckoo Bumblebees: Choice Experiments Reveal Non‐Visual Cues Support Host Detection, but Accuracy Is Low

Entomologia Experimentalis et Applicata, EarlyView.
Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

Bombus terrestris Linnaeus 1758

, 2017
Bombus terrestris (Linnaeus, 1758) Species almost cosmopolitan, with a distribution that extends from northern Europe to north Africa and from central Asia to the Macaronesia, naturally distributed from 0 to 3000 m (Ornosa & Ortiz-Sánchez 2004). It has become increasingly important commercially for its pollination services to agriculture.

Assessing the acute toxicity of insecticides to the buff-tailed bumblebee (Bombus terrestris audax) [PDF]

, 2020
The buff-tailed bumblebee, Bombus terrestris audax is an important pollinator within both landscape ecosystems and agricultural crops. During their lifetime bumblebees are regularly challenged by various environmental stressors including insecticides ...

Floral richness drives flower–insect networks in city gardens and allotments

Ecological Entomology, EarlyView.
Floral richness was the main driver of flower visits within green spaces whilst green space in the surrounding landscape influenced flower visits by amplifying the effects of floral richness. Native plants received more visits than non‐native plants, although flower visitor richness to non‐native plants increased later in the season as non‐native plant

Honeybees directly outcompete other flower visitors through interference competition on shared resource

Ecological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

RNA editing is abundant and correlates with task performance in a social bumblebee

Nature Communications, 2019
Bumblebee workers are genetically highly similar but they show different behaviors such as brood care and foraging. Here the authors report a high level of ADAR-mediated RNA editing in the bumblebee Bombus terrestris and its weak correlation to task ...

Urban habitat fragmentation and floral resources shape the occurrence of gut parasites in two bumblebee species

Ecology and Evolution, 2023
Urbanization and the expansion of human activities foster radical ecosystem changes with cascading effects also involving host‐pathogen interactions. Urban pollinator insects face several stressors related to landscape and local scale features such as ...

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...
