First record of the great fir bark beetle Pityokteines curvidens (Germ.) pest in blue spruce (Picea pungens Engelm.) species in Turkey.
The trade of live plants and seeds is becoming one of the important ecological problems in terms of the easy transportation of invasive species of foreign origin to different countries and the access of native invasive species to different food sources. It has been determined that Picea pungens (Engelm), one of the exotic species widely used in landscaping in parks and gardens in the city center of Düzce, has dried up between 2020 and 2021. The damaged trees were examined and the bark parts were removed with the help of a knife in such a way that they were not very deep, and they were placed in locked nylon refrigerator bags and brought to the laboratory. Photographs of the trees damaged during the investigation were taken. The identification processes of the insects brought to the laboratory were carried out by looking at the relevant sources. Picea pungens, In this study, it was detected for the first time in Turkey as the host of the Great fir bark beetle Pityokteines curvidens (Germ.). Pityokteines curvidens has the potential to be an important pest of Picea pungens, which is used as an ornamental plant in parks and gardens. Therefore, screening activities for Pityokteines curvidens should be continued and protective measures should be taken.
