Anatolia, with a deep-rooted fruiting culture, is the center of biological diversity for many fruits, including apples and walnuts. This study was conducted in Hakkari province, located in the Southeastern Region of Türkiye, in 2023–2024. Cydia pomonella is one of the most important pest causing economic losses in apple and walnut orchards. The primary objective of this study was to (i) monitor population dynamics of the pest, (ii) determine the infestation rate in apples and walnuts, and (iii) molecular characterization of C. pomonella by using the partial mitochondrial Cytochrome Oxidase subunit I (COI) gene. The results showed that the pest exhibits an active flight period of approximately six months, spanning from May to October, and it produces three to four generations. The average infestation rates for both years in apple orchards were found to be 21.5%, 15%, 9% in Çığlı, Yeşilçeşme, Köprülü locations, respectively. Whereas it was detected as 20%, 18.5%, and 6.5% in wllnut orchards in Çığlı, Yeşilçeşme, and Emirşaban, respectively. When the COI gene sequences of C. pomonella collected in this study were analyzed using the Basic Local Alignment Search Tool (BLAST) analysis, it was determined that all samples showed high similarity. Phylogenetic analysis revealed that all specimens in the present study formed a single clade, indicating they were closely related to each other, and no differences were observed in the host-based insects collected from apple and walnut. However, the samples collected from Hakkari showed the closest relationship with the insects collected from Bursa, Erzurum, and İzmir in previous studies. Within the scope of this study, It was determined that although the samples obtained from Hakkari province were grouped together in a different clade, they were closely related with other invasive and adaptive populations in Türkiye. To our knowledge, this is the first report on the prevalence, damage status and molecular characterization of this pest in Hakkari province.
