Parasitoids of the apple ermine moth, Yponomeuta malinellus Zeller, 1838 (Lepidoptera: Yponomeutidae), in the Coruh Valley, Erzurum Province, Turkey

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.
