This study was conducted in the Balcalı location of Adana province in 2022 and 2023 to determine the Thysanoptera fauna on bitter orange trees used for landscaping purposes. Thrips were collected from the flowers and fruits of the trees using the beating method. As a result of the study, 14 species were identified. The most common species, all belonging to the family Thripidae, were: Western flower thrips, Frankliniella occidentalis (Pergande) (33.14%), Oxythrips ajugae Uzel (20.66%), and Rubus thrips, Thrips major Uzel (15.08%). Only a few predatory thrips species from the genus Aeolothrips (Thysanoptera: Aeolothripidae) were found. Thrips were collected mainly from the flowers of the trees. It was recorded that O. ajugae and T. major reproduced in the flowers. The thrips species used the bitter orange trees as temporary habitats and did not cause damage to various organs of the trees.
