Abstract:

In the 1997 studies in the Balçova and Bornova districts of Izmir, from harmful species in pepper greenhouses; two-point red spider [( Tetranychus urticae Koch. Aphis gossypii Glover, Myzus persicae Sulzer (Hom.Aphididae), grain tripsi (Haplothrips distingundus Uzel) (Thys.Thripidae, Liriomyza bryoniae (Kaltenbach) L.trifolii (Burges), L.huidobrensis Blanchard (Dip.:Agromyzidae), Tobacco white-sine ( Bemisia tabaci Gern) and Sera white ( Trialeurodes vaporariorum Westw.) (Hom.:Aleyrodidae), leaf pires [ Asymmetrasca decedens (Paoli), Empoasca decipiens Paoli (Hom.Cicadellidaae) is determined. The results of the studies were found that at the beginning of the vegetation of the Leaf gallery and the leaf beans, the tobacco beans, the two-point red spider, the leaf beans at the end of the vegetation, the grain tripsi reached the maximum in the middle of the vegetation. There was no medication in the water. As a result, natural enemies were preserved and their intensity increased at the beginning of the season and under pressure the harmful. Sheet gallery populations larva parasitoitis, Diglyphus isaea (Walker) (Hym.Eulophidae is under pressure. Diaretiella rapae (M'ınst) in the population of leaves (Hym.:Aphidiidae), Aphidius matricariae Hal., Lysiphlebus fabarum Marshall, Trioxys angelicae (Hal.) and Hym. Aphidiidae) was determined at the beginning of the cultivation period, but no parasitization was recorded after the occurrence of predators. The populations of leaves are under pressure by Propylaea quatuordecimpunctata (L.), Adonia variegata (Goeze) (Col.:Coccinellidae), Sphaerophoria scripta (L.) (Dip.Syphidae and Chrysoperla carnea (Steph.) and Neur.It is found that Chrysopidae is effective. Stethorus gilvifrons (Muls.Scymnus rubromaculatus (Goeze), S. apetzi Mulsant, S.interruptus (Goeze), S.frontalis (Fabricius) (Col.:Coccinellidae), Chrysoperla carnea (Steph.) and Neur.Chrysopidae, Scolothrips longicornis Priesner (Thy.Thripidae and Typhlodromus pyri (Scheuten) (Acarina:Phytoseiidae) It has been concluded that caliginosus plays an important role in the remaining under pressure of the white populous population.
