İzmir ilinde örtü altında yetiştirilen patlıcanda bulunan zararlılar ile bunların doğal düşmanları ve popülasyon gelişmeleri üzerinde çalışmalar.

Abstract

The pests and the natural enemies were determined on protected eggplant in 1997 in Izmir province of Turkiye. Tetranychus urticae Koch. (Acarina:Tetranychidae), and Myzus persicae (Sulzer) (Hom.:Aphididae) were found to be the major pests. Bemisia tabaci Gern (Hom.:Aleyrodidae), Asymmetrasca decedens Paoli, Empoasca decipiens Paoli (Hom.:Cicadellidae), Trips tabaci Lindeman and Frankliniella occidentalis (Pergande) (Thy.:Thripidae), Liriomyza bryoniae (Kaltenbach) (Dip.:Agromyzidae) were found to be the secondary pests. Eristalodes taeniops Wiedeman (Dip.:Syrphidae) and Epitrix hirtipennis (Melsh) (Col.:Chrysomelidae) were found very rarely on protected eggplant. Natural enemies suppressed the secondary pests if there was no disturbance of the natural balance. L. bryoniae were suppressed by the larval parasitoids, Diglyphus isaea ( Walker) (Hym.:Eulophidae). The parasitoid of M. persicae , Diaretiella rapae (M'inst) , parasited M. persicae in the early vegetation. However, after the predators were seen in the plastic tunnels, the parasitism was not recorded. Propylea quotuordecimpunctata (Goeze) and Adonia variegata (Goeze) (Col.:Coccinellidae); Chrysoperla carnea (Steph.) (Neur.: Chrysopidae); Aphidoletes aphidimyza (Rond.) (Dip.:Cecidomyiidae); Sphaerophoria scripta (L.) (Dip.:Syrphidae) were effective on M.persicae population. Stethorus gilvifrons (Muls), Scymnus rubromaculatus (Goeze), S.apetzi Mulsant, S.interruptus (Goeze), S. frontalis (Fabricius) (Col.:Coccinellidae); C.carnea ; Deraeocoris serenus D.Sc., Orius niger (W.) (Het.:Miridae) were effective on T.urticea population. O.niger and Aelothrips collaris Priesner (Thy.:Thripidae) were effective on T.tabaci and F.occidentalis populations. Macrolophus caliginosus (Wgn.) (Het.:Miridae) were effective on whitefly population. O.niger, C.carnea were effective on Cicadellidae species.
