The rose tortrix moth, Archips rosana (L.) (Lepidoptera: Tortricidae), is a pest that causes serious crop losses in apple orchards throughout the world. In this study, the population dynamics of A. rosana and its associated parasitoids were investigated in two provinces of Western Turkey (Denizli and Usak) in 2018 and 2019. A total of 318 egg masses, 300 larvae, and 129 pupae were collected from the survey areas. Although no parasitoids were detected in egg masses, ten parasitoid species belonging to Braconidae, Chalcididae, and Ichneumonidae (Hymenoptera), and Tachinidae (Diptera), were reared from the samples of larvae and pupae. Phytodietus astutus (Gravenhorst) (Ichneumonidae) was the most abundant parasitoid species, with a relative abundance of 35.1%, followed by Itoplectus maculator (Fabricius) (Ichneumonidae) represented by 27% of the recovered parasitoids. Moreover, P. astutus and Scambus inanis (Schrank) (Ichneumonidae) reared from the samples are the first records from Turkey, while Cotesia glomerata (L.) (Braconidae), Exochus sp.(Ichneumonidae), and Nemorilla maculosa (Meigen) (Tachinidae) are the first records from A. rosana. Using pheromone traps in the apple orchards, the first adult of A. rosana was caught on May 24 in Civril (Denizli) and on May 30 in Sivasli (Usak) in 2019.
