Flowering forbs for field margins: selecting species that optimize ecosystem services


Abstract: The aim of this study was to assess the attractiveness of flowers to target groups ofbeneficial insects. Water trap samples were taken throughout the entire period of inflorescenceand were accompanied by sweep net sampling in early summer. Samples were assessed for targetinsect groups (predatory beetles, true bugs, aphids, hoverflies and Parasitica) that are known toprovide ecosystem services in farm landscapes (such as pollination, conservation and pestcontrol). Yarrow and Oxeye daisy were the most promising flowering plants, attracting multiplebeneficial target groups. These species seem to be the most promising for use in flowering fieldmargins.
