Çoruh Vadisi’nde (Erzurum, Türkiye) elma ağ kurdu [Yponomeuta malinellus Zeller, 1838 (Lepidoptera: Yponomeutidae)]’nun parazitoidleri

Parasitoids of the apple ermine moth, Yponomeuta malinellus Zeller1838 (Lepidoptera: Yponomeutidae), in the Çoruh Valley, Erzurum Province, Turkey

Abstract

Parasitoids of Yponomeuta malinellus Zeller, 1838 (Lepidoptera: Yponomeutidae), in various host plants (especially apple) were investigated in the Coruh Valley, Erzurum Province, Turkey, during 2015 and 2016. The parasitoids associated with Y. malinellus were reared in a laboratory, with a total of 255 individual parasitoids emerging from three families, Braconidae, Ichneumonidae (Hymenoptera), and Tachinidae (Diptera). Six parasitoid species, Habrobracon concolorans (Marshall, 1900) (Hymenoptera: Braconidae), Diadegma armillatum (Gravenhorst, 1829), Trieces tricarinatus (Holmgren, 1858), Itoplectis tunetana (Schmiedeckneckt, 1914), Itoplectis maculator (Fabricius, 1775) (Hymenoptera: Ichneumonidae) and Bessa parallela (Meigen, 1824) (Diptera: Tachinidae), were determined. Of these, H. concolorans was reared from Y. malinellus for the first time. Apple ermine moth is therefore a new host for this parasitoid. The combined contribution of the parasitoids in parasitizing apple ermine was 25.5%, with D. armillatum being the most numerous accounting for 5.5% of all parasitoids reared

Özet

Çoruh Vadisi'nde 2015-2016 yıllarında yürütülen bu çalışma, özellikle elma ağaçlarında konukçu olan, elma ağ kurdu [Yponomeuta malinellus Zeller, 1838 (Lepidoptera: Yponomeutidae)]'nun parazitoidlerini belirlemek amacıyla yapılmıştır. Braconidae, Ichneumonidae ve Tachinidae familyalarına bağlı toplam 255 parazitoid örneğinin laboratuvarda çıkışı sağlanmıştır. Habrobracon concolorans (Marshall, 1900) (Hymenoptera: Braconidae); Diadegma armillatum (Gravenhorst, 1829), Trieces tricarinatus (Holmgren, 1858), Itoplectis tunetana (Schmiedeckneckt, 1914), Itoplectis maculator (Fabricius, 1775) (Hymenoptera: Ichneumonidae) ve Bessa parallela (Meigen, 1824) (Diptera: Tachinidae) olmak üzere belirlenen 6 parazitoid tür içerisinde, H. concolorans için elma ağ kurdu yeni bir konukçudur. %25.5 oranında parazitlenmenin görüldüğü çalışmada, en fazla çıkış %5.5 ile D. armillatum'da görülmüştür
