Plants on karst that attract predatory insects

Abstract: One of the main problems in vineyards and olive orchards on karst is very scarce source of plants useful for conservation biological control which can survive high temperatures and lack of water during the summer months. The aim of this research was to choose plants as potential elements of ecological infrastructure which could play important role in attracting of beneficial insects in particular predators. This research was conducted on the island of Pašman (Zadar County – Croatia) from 2015 to 2016. The following plants were selected; Arbutus unedo L., Dittrichia viscosa (L.) Greuter, Dorycnium hirsutum (L.) Ser, Helichrysum italicum (Roth) G. Don, Salvia officinalis L., Spartium junceum L., Origanum vulgare L. Between predator species Deraeocoris scach Fabricius, Deraeocoris ruber L., Geocoris erytrocephalus Lepeletier & Serville, Scymnus spp. and Rhynocoris rubricus Germar were found.
