USE OF Orius laevigatus TO CONTROL Frankliniella occidentalis (THYSANOPTERA: THRIPIDAE) POPULATION IN GREENHOUSE PEPPER

Although chemical pesticides play a vital role in controlling the number of harmful insects, they also contribute to accelerate pollution soil, air and water. Due frequent use, insects become resistant active ingredients very quickly; destroy natural enemies pests, have effect on humans. Accordingly, application biological protection, that is, use living organisms (predators parasites) plant protection programs protected areas, takes larger scale worldwide rather than pesticides. The aim our research was determining effectiveness pirate bug Orius laevigatus (Hemiptera: Anthocoridae) reducing population Western flower thrips (Frankliniella occidentalis). Experiment set commercial greenhouses (3 unheated plastic tunnels, ca. 125 m2, each), located area Dabilje, Republic Macedonia, during 2019 2020. results obtained correspond expectation trips.
