Studies on the pests, their natural enemies and population developments on protected eggplant in İzmir province.

Abstract

Pests and their natural enemies were determined on protected aubergine in 1997 in İzmir province of Turkey. Tetranychus urticae and Myzus persicae were the major pests. Bemisia tabaci, Asymmetrasca decedens, Empoasca decipiens, Thrips tabaci, Frankliniella occidentalis and Liriomyza bryoniae were the secondary pests. Eristalodes taeniops and Epitrix hirtipennis were very rarely found on protected aubergine. The natural enemies suppressed the secondary pests provided that the natural balance is undisturbed. L. bryoniae was suppressed by the larval parasitoid, Diglyphus isaea. The parasitoid, Diaretiella rapae [Diaeretiella rapae] parasitized M. persicae in the early vegetation. However, parasitism was no longer recorded after the detection of predators in the plastic tunnels. Propylea quatuordecimpunctata, Adonia variegata [Hippodamia variegata], Chrysoperla carnea, Aphidoletes aphidimyza and Sphaerophoria scripta were effective parasitoids of M. persicae. Stethorus gilvifrons, Scymnus rubromaculatus, S. apetzi, S. interruptus, S. frontalis, C. carnea, Deraeocoris serenus and Orius niger were effective on T. urticae population. O. niger and Aelothrips collaris [Aeolothrips collaris] were effective on T. tabaci and F. occidentalis populations. Macrolophus caliginosus were effective on whitefly population. O. niger and C. carnea were effective on Cicadellidae species.
