Spidermite [ <em>Tetranychus urticae </em> Koch. (Acar-ina:Tetranychidae)], aphids [ <em>Aphis gossypii </em> Glover, <em>Myzus persicae </em> Sulzer (Hom.: Aphididae)], whiteflies [ <em>Bemisia tabaci </em> Gern and <em>Trialeurodes vaporariorum </em> Westw. (Hom.:Aleyrodidae)], leafhoppers [ <em>Asymmetrasca decedens </em> (Paoli), <em>Empoasca decipiens </em> Paoli (Hom.:Cicadellidae)], thrips [ <em>Haplothrips distingundus Uzel </em> (Thys.:Thripidae)] andleafminers [ <em>Liriomyza bryoniae </em>(Kaltenbach) <em> L.trifolii </em>(Burges), <em>L.huidobrensis Blanchard </em> (Dip.:Agromyzidae)] were found to be the pests on the protected pepper. Aphid and leafminers densities were reach to the maximum at the beginning of the season. Whiteflies,  spidermite and leaf hoppers were high in densities towards the end of the season. The population density of <em>H.distingundus </em> are high at the middle of the season.  There was no treatment against any pests in the plastic tunnels. Therefore the beneficial were conserved and their populations increased at the begining of the season and suppressed the pest populations. Leafminerswere suppressed by the larval parasitoids, <em>Diglyphus </em> <em>isaea </em> (Walker)(Hym.:Eulophidae). The parasited aphids[( <em>Diaretiella rapae </em> (M’ınst) <em>Lysiphlebus fabarum </em> Marshall, <em>Aphidius matricariae </em>Hal., <em>Trioxys angelicae </em> (Hal.) (Hym.:Aphidiidae)] were seen in the early vegetation. After the predators were seen in the plastic tunnels, the parasitism weren’t recorded in the aphid population. <em>Propylea quotuordecimpunctata </em> (Goeze), <em>Adonia variegata </em>(Goeze)(Col.:Coccinellidae), <em>Chrysoperla carnea </em>(Steph.) (Neur.:Chrysopidae), <em>Aphidoletes aphidimyza </em>(Rond.)(Dip.:Cecidomyiidae), <em>Sphaero-phoria scripta </em> (L.)(Dip.:Syrphidae) were effective on aphid population. <em>Stethorus gilvifrons </em> (Muls.), <em>Scymnus rubromaculatus </em> (Goeze), <em>S.apetzi </em> Mulsant, <em>S.interruptus </em>(Goeze), <em>S.frontalis </em> (Fabricius)(Col.:Coccinellidae), <em>C.carnea </em>, <em>Scolothrips longicornis </em>Priesner (Thys.:Thripidae) were effective on spidermite population. <em>Macrolophus </em> <em>caliginosus </em> (Wgn.) (Het.:Miridae) were effective on whiteflies population.}, number={3}, publisher={TARIM VE ORMAN BAKANLIĞI EĞİTİM VE YAYIN DAİRESİ BAŞKANLIĞI}
