Some thysanopteran (thrips) species are recognized as pests of ornamentals. They cause typical feeding damageby scarring petals, flowers buds or leaves; thus resulting in a decrease at market values of ornamentals.However, thrips composition and importance on ornamental plants in Turkey are not well-understood.Thysanopteran species on ornamentals grown in the parks, home gardens and greenhouses in the Çukurovaregion of Turkey were investigated during years 2013-2014. Thrips were collected by shaking the plants onto thewhite tray. Thrips were slide-mounted and identified. In this work, 62 plant species belonging to 35 plant familieswere investigated for thrips. A total of 1875 thrips adults were extracted from a total 256 plant samples. A total of23 thysanopteran species belonged to 3 families of order Thysanoptera were determined: Aeolothripidae (6species), Phlaeothripidae (5 species) and Thripidae (12 species). Haplothrips tamaricinus Priesner was the firsttime detected in Turkey. Ornamentals belonged to family Asteraceae were more attractive to thrips, bearingrelatively high species numbers and high numbers of adult thrips. Majority of thrips were collected from multiflowering ornamentals. Only Frankliniella occidentalis (Pergande) was recorded on the ornamentals growncommercially in greenhouses, infesting most of herbaceous plant species with flowers. The most notable specieswere in descending order F. occidentalis, Neohydathothrips samayunkur (Kudo) and Thrips tabaci Lind. Thethrips fauna was dominated by F. occidentalis, this thrips being found in 51.17% of the samples and consisting81.47 % of the specimens. The second major species N. samayunkur comprised 5.07% of the samples andaccounted for 7.72% of the specimens.
