Leaf-pest insects, biology and population changes in Antalya eucalyptus trees

This study was performed from 2017 to 2018 as "Master's Thesis" at Isparta University of Applied Sciences, The Institute for Graduate Education, Department of Forest Engineering on the purpose identification of leaf-pest insects, biology and population changes in Antalya eucalyptus trees. For this purpose, it was detected the areas of distribution of eucalyptus have been identified and were recorded pest species and parasitoids of pests seen in the leaf parts of the trees in these areas, the damage situation in trees and information of areas. As a result, five leaf pest species and six parasitoid species were found in eucalyptus trees in Antalya. Pest species are Leptocybe invasa (Fisher & La Salle, 2004), Ophelimus maskelli (Ashmead, 1900) (Hymenoptera: Eulophidae), Glycaspis brimblecombei (Moore, 1964), Platyobria biemani (Taylor, 1987) (Hemiptera: Psyllidae) and Aphis gossypii Glover, 1877 (Hemiptera: Aphididae). Platyobria biemani for Turkey eucalyptus pest fauna and Glycaspis brimblecombei for the Antalya region were identified as new records. Parasitoid species from galls of Leptocybe invasa are Selitrichodes kryceri Kim & La Salle, 2008 (Hymenoptera: Eulophidae: Tetrastichinae), Quadrastichus mendeli Kim & La Salle, 2008 (Hymenoptera: Eulophidae: Tetrastichinae) and Megastigmus sp. (Hymenoptera: Torymidae). We found that larvae and pupa parasitoid of Ophelimus maskelli was Closterocerus chamaeleon (Girault, 1922) (Hymenoptera: Eulophidae), larvae parasitoid of O. maskelli was Stethynium ophelimi Huber, 2006 (Hymenoptera: Mymaridae), and larvae parasitoid of Glycaspis brimblecombei was Psyllaephagus bliteus Riek, 1962 (Hymenoptera: Encyrtidae). S. kryceri, Q. mendeli and S. ophelimi were determined as new records for Turkish fauna. Keywords: Eucalyptus, leaf pest, biology, natural enemy, Antalya.
