Field-level clothianidin exposure affects bumblebees but generally not their pathogens
Nature Communications, 2018 The potential impact of neonicotinoid field exposure on bumblebee microbiota remains unclear. In a landscape—scale study, Wintermantel et al. show that whilst exposure to clothianidin impacts Bombus terrestris performance, it does not affect levels of ...

BumbleBEEP: A Sensor System for Bumblebee Colony Monitoring
Entomologia Experimentalis et Applicata, EarlyView.We present a bumblebee colony monitoring system, BumbleBEEP. The system is fitted with thermometers and a custom weight sensor. These record data up to every 15 min, recording bumblebee brood nest temperature, environmental ambient temperature, and colony growth.

Sweet connections: the role of honeydew in supporting wild Bombus terrestris populations (Hymenoptera, Apidae) – a case study from Türkiye [PDF]
Journal of Hymenoptera ResearchHoneydew is a sugary excretion produced by sap-feeding hemipterans, such as scale insects and aphids. It has been regarded predominantly as a food resource for predators and omnivores insects.

Entomologia Experimentalis et Applicata, EarlyView.Application of the fungicide Switch 62.5 WG in garden strawberry (Fragaria × ananassa), targeting Botrytis cinerea, reduced sawfly (Cladius spp.) herbivory by up to 94% and improved fruit quality. This non‐target effect also spilled over to neighbouring untreated plants, lowering damage by 46%.

Measurement of electric charges on foraging bumblebees (Bombus terrestris)
Journal of Physics: Conference Series, 2019 Abstract Bumblebees carry electric charge. Almost always positive, this charge facilitates pollen transfer between bumblebee and flower during pollination and is likely to play a role in the detection of electric fields. Models of the Coulomb forces acting on pollen grains during pollination are predominantly based upon laboratory ...

Ecological Entomology, EarlyView.In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Ecological Entomology, EarlyView.Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.
