<p>The cherry slugworm, <i>Caliroa cerasi</i> (L.) (Hymenoptera: Tenthredinidae), is a foliar pest of economic importance in temperate sour cherry (<i>Prunus cerasus</i> L.) orchards. While its damage symptoms are well documented, directional feeding preferences - defined here as the non-uniform distribution of larval feeding damage across different canopy orientations within trees and orchard directions - with in tree canopies and orchard orientataion have not previously been investigated. This study examined the spatial distribution of <i>C. cerasi</i> damage in 11 sour cherry orchards in Erzincan Province, Türkiye, during the 2021 and 2022 growing seasons. Feeding damage was assessed by sampling leaves from the four cardinal canopy directions in multiple orchards. Feeding damage was assessed under a stereomicroscope and analyzed in relation to canopy direction, orchards orientation and their interaction. Larval damage was significantly higher on the eastern sides of tree canopies and in orchards oriented to the southeast in both study years. The interaction between canopy direction and orchard orientation was also significant, with the east × southeast combination consistently exhibiting the highest damage levels. These findings indicated that <i>C. cerasi</i> exhibits non-uniform spatial feeding damage pattern influenced by canopy and orchard orientation. Incorporating directional damage patterns into monitoring and control strategies may improve the efficiency of integrated pest management (IPM) programs, particularly in systems where targeted interventions are preferred.</p>
