Organic farming positively affects honeybee colonies in a flower‐poor period in agricultural landscapes

| Type artikkel: Publisert studie

Kategori: Pollinerende insekter, Økologisk landbruk

1. Conventional farming has been implicated in global biodiversity and pollinator declines and organic farming is often regarded as a more ecological alternative. However, the effects of organic farming on honeybees remain elusive, despite honeybees’ importance as pollinators of crops and wild plants.

Wild Pollinators Enhance Fruit Set of Crops Regardless of Honey Bee Abundance

| Type artikkel: Publisert studie

Kategori: Insekter, Pollinerende insekter

The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed pollinators such as honey bees, is unclear. We found universally positive associations of fruit set with flower visitation by wild insects in 41 crop systems worldwide. In contrast, fruit set increased significantly with flower visitation by honey bees in only 14% of the systems surveyed.
