Abstract
The current study aimed to determine parasitoids of Yponomeuta malinellus Zeller, 1838 (Lepidoptera: Yponomeutidae) in apple trees in the Çoruh Valley, Erzurum Province, Türkiye during 2019-2020 summer. The parasitoids associated with Y. malinellus were reared in a laboratory, with a total of 137 individual parasitoids emerging from family Ichneumonidae (Hymenoptera). Among the identified species Trieces facialis (Thomson, 1887), Itoplectis tunetana (Schmiedeknecht, 1914) and Pimpla turionellae (Linnaeus, 1758) were determined as pupal parasitoid. Of these, Trieces facialis has been obtained from Y. malinellus our country first time and also is new for the Turkish Ichneumonidae fauna. In this study of the Çoruh Valley, the mean parasitism rate was %27.4.
