Colour reverse learning and animal personalities: the advantage of behavioural diversity assessed with agent-based simulations [PDF]
, 2012 Foraging bees use colour cues to help identify rewarding from unrewarding flowers, but as conditions change, bees may require behavioural flexibility to reverse their learnt preferences.

Metabolomics-based biomarker discovery for bee health monitoring : a proof of concept study concerning nutritional stress in Bombus terrestris [PDF]
, 2019 Bee pollinators are exposed to multiple natural and anthropogenic stressors. Understanding the effects of a single stressor in the complex environmental context of antagonistic/synergistic interactions is critical to pollinator monitoring and may serve ...

Methods in Ecology and Evolution, EarlyView.Abstract Plant–pollinator interactions are fundamental to the functioning of natural ecosystems and the enhancement of agricultural productivity. An effective support of pollinator communities necessitates a comprehensive understanding of the mechanisms underlying pollinator attraction and nutritional preferences.

Continuous Radar Tracking Illustrates the Development of Multi-destination Routes of Bumblebees
Scientific Reports, 2017 Animals that visit multiple foraging sites face a problem, analogous to the Travelling Salesman Problem, of finding an efficient route. We explored bumblebees’ route development on an array of five artificial flowers in which minimising travel distances ...

Strong diel variation in the activity of insect taxa sampled by Malaise traps
Ecological Entomology, EarlyView.Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

Flower Associations of Mimetic Syrphidae (Diptera) in Northern Michigan [PDF]
, 2017 Collections of specialized (high fidelity) mimetic Syrphidae in northern Michigan revealed 19 species associated with 18 flowering plants. Almost 97% of these syrphids were taken on seven plant species or species groups, all with conspicuous white or ...

EFFICIENCY OF CUCUMBER (Cucumis sativus L.) POLLINATION BY BUMBLEBEES (Bombus terrestris)
Acta Scientiarum Polonorum: Hortorum Cultus, 2011 The cucumber crop size depends not only on the cultivar and agrotechnical conditions but also on proper pollination of flowers. The aim of the work was the investigation of the efficiency of bumblebees used in the cultivation of cucumber on the yield ...

Acta Agrobotanica, 2014 This study was an attempt to show synanthropic phytocoenoses of the city of Lublin which are potentially valuable to pollinating insects such as bumblebees. B. terrestris and B. lapidarius as well as B. lucorum, B. hypnorum and B. pascuorum were found to

A failed invasion? Commercially introduced pollinators in Southern France [PDF]
, 2009 The natural diversity of Bombus terrestris subspecies could be under threat from the commercialisation of bumblebees. Therefore, to determine whether commercially imported bumblebees are able to establish and spread, we carried out
