Homing ability of the bumblebee bombus terrestris (hymenoptera: apidae)
, 2001 The ability of bumblebees to locate their nest site following artificial displacement was investigated. Bombus terrestris (Hymenoptera: Apidae) workers were marked with numbered tags and displaced up to 15 km from their nest. Bees returned from distances

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 ...

Rapid disruption of pollination function by the invasive plant Impatiens glandulifera
Plant Biology, EarlyView.Invasion by Impatiens glandulifera rapidly disrupts pollination of the native plant Stachys sylvatica by altering pollen transport by shared bumblebee pollinators. A short‐term field introduction revealed a dramatic decline in conspecific pollen deposition within 4 days, showing that pollination function can collapse quickly following invasion, even ...

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.

Plant Biology, EarlyView.Expression of genetic differences depends on the experimental environment as seen in flowering time differences between ancestors and descendants that emerge in climate chambers but not in greenhouse or garden conditions. Abstract Common‐environment experiments are important to study genetically based phenotypic variation within and among plant ...

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 ...
