Orchards in natural habitats draw bee diversity, improve apple production

Cornell University – Apple orchards surrounded by agricultural lands are visited by a less diverse collection of bee species than orchards surrounded by natural habitats, according to a new Cornell University-led study, published in the journal Science. In turn, apple production suffers when fewer, more closely-related species of bees pollinate an orchard. Production improves in orchards […]

Fungicides emerge as improbable villain against bees

Cornell University – When a Cornell-led team of scientists analyzed two dozen environmental factors to understand bumblebee population declines and range contractions, they expected to find stressors like changes in land use, geography or insecticides. Instead, they found a shocker: fungicides, commonly thought to have no impact. “Insecticides work; they kill insects. Fungicides have been […]

Field tests show sustained neonicotinoid exposure negatively affects bees

American Association for the Advancement of Science – In two of the first large-scale, field-realistic studies to date, researchers in Europe and Canada have affirmed what’s been hypothesized about neonicotinoids — that prolonged exposure to these insecticides negatively affects bees. Their results reveal that local environment and species influence the impact of these widely used […]
