This dataset describes the effects of three neonicotinoid seed treatments (clothianidin, thiamethoxam and a control) applied to winter sown oilseed rape in Hungary, Germany and the UK on wild pollinators. This dataset focuses on two wild pollinator model systems, specifically the solitary bee Osmia bicornis and bumblebee Bombus terrestris. The data describes population responses in terms of reproductive cell production (O. bicornis), numbers of different developmental stages in colonies (B. terrestris) as well as the presence of neonicotinoid residues in pollen and nectar collected by both species. This research was undertaken in 2015 using funding from the Natural Environmental Research Council on an experimental platform funded by Syngenta Ltd. and Bayer CropScience.

Microsatellite data for five species of common and declining bumblebee (Bombus terrestris, B. lapidarius, B. pascuorum, B. hortorum and B. ruderatus) collected across the Hillesden Estate, Buckinghamshire, UK, in summer 2011. Worker genotypes were determined from individuals sampled across an agricultural landscape and queen genotypes were reconstructed from sampled worker offspring. Data were collected as part of a project led by the Centre for Ecology & Hydrology, funded under the Insect Pollinators Initiative.

This dataset contains locations of worker bumblebees of five species (Bombus terrestris, B. lapidarius, B. pascuorum, B. hortorum, B. ruderatus) across an agricultural landscape centred on the Hillesden Estate, Buckinghamshire, UK. Locations were recorded in the field using a handheld GPS unit. Workers were non-lethally DNA sampled between June and August 2011, and genetic analysis used to confirm species and assign individuals to full-sib groups (colonies). Data were collected as part of a project led by the Centre for Ecology & Hydrology, funded under the Insect Pollinators Initiative.

This dataset describes an experimental test of potential over yielding effects on fruit set and average fruit size for tomato plants grown in the presence of three pollinator combinations: (1) the bumblebee Bombus terrestris (2) Lasioglossum spp. and (3) and additive combination of B. terrestris and Lasioglossum spp. The experimental design includes no pollinator controls nested within individual tomato plants exposed to the above pollinator species treatment combinations. This research was undertaken in 2017 and funded though a CEH Commercial Innovation Fund (National Capability) project supported by the Natural Environmental Research Council (Project NEC06344).
