Damage, biology and natural enemies of the green oak moth, [Tortrix viridana L. 1758 (Lep.; Tortricidae)] in Dinar district oak forests

Abstract

In this study, the distribution of Tortrix viridana in Dinar region, its damage to the host plant stands as well as its biology and natural enemies were explored. Samples were examined and collected in the research area periodically from 2012 to 2014. The harmful insects were found on three oak species in the research area. They were Quercus coccifera, Q. infectoria and Q. pubescens. It was observed that adult insect emergence started in late May and continued decreasingly in June. It was also found that the laying period was in winter and the larvae hatched starting from mid-April and onwards, and the young larvae initially started feeding on the buds of oak trees. The pupa was observed to make a generation in the leaves in a year starting from mid-May. Three bird species that feed on the larvae of T. viridana and that were Phylloscopus boneli (Vieillot) (Passeriformes: Sylviidae), Parus caeruleus L. ve Parus major L. (Paseriformes: Paridae) were observed during the study period. Forficula auricularia L. (Dermaptera: Forficulidae) as a predator species and Itoplectis maculator (Fabr.) (Hym.; Ichneumonidae), Brachymeria tibialis (Walker) (Hym.; Chalcididae), Monodontomerus aereus Walker (Hym.; Torymidae), Pteromalus semotus (Walker) (Hym.; Pteromalidae), Macrocentrus collaris (Spinola) (Hym.; Braconidae) as parasite species were identified. All parasite species except I. maculator were recorded in our country for the first time as the natural enemies of the harmful insects.
