Abstract: This study was carried out between 2020-2021 to determine the relationships between the number of larvae and yield parameters of Cimbex quadrimaculata Müller, 1766 (Hymenoptera: Cimbicidae) in wild and cultivated almond cultivars in Diyarbakır and Elazığ provinces. It has been determined that the pest has a higher population in wild almonds than cultivated almonds, and the yield of almond trees decreases as the number of pests increases. However, it has been determined that this change is different according to tree age and crown projection. When the damage degrees of the pest were examined among the locations, it was determined that the yield of wild almond trees in Keban location in 2020 was less affected by the number of pests than other locations. It was determined that the number of larvae affected the yield parameters more than the other varieties in the cultivated almonds in the Keban location in 2021. It is thought that the pest affects the yield parameters in all locations, regardless of species, and this study will form the basis for model studies on the Economic Damage Threshold (EZE) of this pest.
