Abstract :Fraxinus angustifolia Vahl has fast-growing, valuable wood and the largest forests in the world are in Turkey. Since it is one of the fastest growing species after poplar and alder, new stands are established by planting and it is widely used in urban landscapes and roadside. It has an important place in the urban landscape of Kahramanmaraş, where the study was conducted, and is found on boulevards, main streets, parks and roadsides. In the observations of the species, insect exit holes were observed on the trunk and branches of some individuals and it was determined that there was dark colored discharge from these holes and the presence of skin change parts of the larvae. It was observed that some of the ash trees dried up, and many of them had deformities as a result of the drying of some branches on the trunk, and there was a great decrease in seed yield. In order to determine these damages of the species, insects were examined in the wood samples and Z pyrina L.1761 (Lepidoptera; Cossidae) was identified. The same pest was observed to be very common in walnut (Juglans regia L.) trees in parks and gardens in the city. Approximately 200 trees were visited in the city center using the transect method to determine the level of transmission of the pest. The observations showed that 28% of the ash trees were infected by this pest and based on these findings, it was determined that this moth species is the most important pest of F. angustifolia in Kahramanmaraş province. This research was carried out in Kahramanmaraş city center, located in the Eastern Mediterranean Region, between 12 March and 15 December 2022 to determine the pests of F. angustifolia and to determine the prevalence of Z. pyrina, a polyphagous pest.Keywords : Fraxinus angustifolia, Kahramanmaraş, Peyzaj, Zeuzera pyrina
