Semi-natural habitats and structural elements such as hedgerows, forest edges or permanent grassland offer habitats for beneficial insects such as wild bees and predators of pests. How semi-natural habitats influence pollinators and other beneficials, and how knowledge of this can be used to promote pollinators and beneficials, thereby supporting pollination services and natural pest control, is currently being investigated in the EU FP7 Project QuESSA, with the involvement of Agroscope.
