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 ...

The abundance and pollen foraging behaviour of bumble bees in relation to population size of whortleberry (Vaccinium uliginosum). [PDF]
PLoS ONE, 2012 Habitat fragmentation can have severe effects on plant pollinator interactions, for example changing the foraging behaviour of pollinators. To date, the impact of plant population size on pollen collection by pollinators has not yet been investigated ...

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%.

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.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.

A larval hunger signal in the bumblebee Bombus terrestris
Insectes Sociaux, 2006 Larvae of Bombus terrestris, a pollen-storing bumblebee, are dependent on progressive provisioning by workers. We test the hypothesis that larval cuticular chemicals can act as a hunger signal. We first show with a new classical conditioning experiment, using a Y-shaped tube, that workers can be trained to prefer the extracts of normally fed larvae ...

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

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 ...
