The wild honeybee population of Europe is in decline: Evidence from monitoring studies

Conservation Science and Practice, EarlyView.
Studying the population trends of wild honeybees is possible when considering that managed and wild colonies form different subpopulations within regional honeybee metapopualtions. Abstract Populations of wild western honeybees (Apis mellifera) have been neglected because the species has been considered to consist of managed colonies only.

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.

Fungicide Non‐Target Effects Cause Reduced Sawfly Herbivory in Treated and Neighbouring Strawberry Plants

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%.

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.

Methylation and worker reproduction in the bumble-bee (Bombus terrestris) [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2014
Insects are at the dawn of an epigenetics era. Numerous social insect species have been found to possess a functioning methylation system, previously not thought to exist in insects. Methylation, an epigenetic tag, may be vital for the sociality and division of labour for which social insects are renowned.

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

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 ...

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 ...

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

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.
