Abstract

iiiÖZETÇalisma 2002-2004 yillari arasinda, Isparta ili ve ilçelerindeki meyve agaçlarindazararli Aphidoidea (Homoptera) türleri ve dogal düsmanlarini saptamak amaciylayürütülmüstür.Bölgede; Aphidoidea üstfamilyasina bagli, 3 familyaya ait 8 cins ve bu cinslere bagli14 yaprakbiti türü saptanmistir, türlerden biri ancak cins düzeyinde teshisedilebilmistir. Bu türler; Callaphididae familyasindan Myzocallis coryli (Goetze),Aphididae familyasindan Aphis pomi De Geer, Brachycaudus cardui (Linneus),Bracycaudus helichrysi (Kaltenbach), Dysaphis devecta (Walker), Dysaphisplantaginea (Passerini), Dysaphis pyri (Boyer de Fons.), Dysaphis sp., Hyalopterusamygdali (Blanchard), Hyalopterus pruni (Geoffroy), Corylobium avellanae(Schrank), Myzus cerasi (Fabricius), Myzus persicae (Sulzer) ve Pemphigidaefamilyasindan Eriosoma lanigerum (Hausmann)' dur. Dysaphis plantaginea, Aphispomi ve Dysaphis devecta elmada zararli olmalari ve bölgede yogun elma üretimiyapilmasi nedeniyle sirasi ile en yaygin türler olarak saptanmistir.Yaprakbitlerinin dogal düsmani olarak toplam 20 tür bulunmus olup, Coccinellidae(Coleoptera) familyasindan 8, Syrphidae (Diptera) familyasindan 3, Forficulidae(Dermaptera) familyasindan 1 tür predatör olarak saptanmistir. Hymenopteratakimindan Pachyneuron aphidis Bouché (Pteromalidae), Aphelinus mali(Haldeman) (Aphelinidae), Lipolexis gracilis Foerster, Ephedrus sp., Ephedruspersicae Froggatt, Aphidius matricariae Haliday, Praon volucre (Haliday),Binodoxys angelicae (Haliday) (Braconidae; Aphidiidae) türleri ise parazitoit olarakbelirlenmistir. Dysaphis devecta 8 predatör ve 3 parazitoit tür ile en fazla dogaldüsmana sahip olan tür olmustur.ANAHTAR KELIMELER: Aphidoidea, Isparta, meyve agaçlari, dogal düsman

ivABSTRACTThe study was conducted in fruit trees of Isparta and adjacent areas between 2002and 2004, in order to determine harmful aphid (Homoptera: Aphidoidea) species andtheir natural enemies.In region, 14 aphid species belonging to 8 genera and 3 families of the superfamilyAphidoidea were presented from the research area, one of the species wasdetermined only as genus. The species are; Myzocallis coryli (Goetze) from thefamily Callaphididae, Aphis pomi De Geer, Brachycaudus cardui (Linneus),Bracycaudus helichrysi (Kaltenbach), Dysaphis devecta (Walker), Dysaphisplantaginea (Passerini), Dysaphis pyri (Boyer de Fons.), Dysaphis sp., Hyalopterusamygdali (Blanchard), Hyalopterus pruni (Geoffroy), Corylobium avellanae(Schrank), Myzus cerasi (Fabricius), Myzus persicae (Sulzer) from the familyAphididae, and Eriosoma lanigerum (Hausmann) from the family Pemphigidae.Among the species Dysaphis plantaginea, Aphis pomi and Dysaphis devecta whichare harmful on apples, are the most common species in the area respectively becauseof the high amount of apple production.A total of 20 species were detected as natural enemies of aphids. 8 species from thefamily Coccinellidae (Coleoptera), 3 from Syrphidae (Diptera), and 1 species fromForficulidae (Dermaptera) were found as predators. In addition, Pachyneuron aphidisBouché (Pteromalidae), Aphelinus mali (Haldeman) (Aphelinidae), Lipolexis gracilisFoerster, Ephedrus sp., Ephedrus persicae Froggatt, Aphidius matricariae Haliday,Praon volucre (Haliday) and Binodoxys angelicae (Haliday) (Braconidae;Aphidiidae) were determined as parasitoids belonging to the order Hymenoptera.Dysaphis devecta has the largest number of natural enemies with 8 predators and 3parasitoids.KEY WORDS: Aphidoidea, Isparta, fruit trees, natural enemies
