We are studying how non-crop plants, planted in the margins of wineyards and pomegrenate orchards, affect local natural enemies of crop pests. These studies are conducted in collaboration with Drs. Avi Bar-Massada, Elad Chiel, Efrat Gavish-Regev, Ally Harari, Yael Lubin, Arik Rosenfeld, Rakefet Sharon and Tirtzah Zahavi. They are funded by Nekudat Hen Foundation, by the Israeli Ministry of Enviromental Protection and by the Israeli Ministry of Agriculture.
