This study was carried out during 2006-2007 in Isparta province, to determine harmful and beneficial species and to reveal important species in Oil-bearing rose production areas. In the study, population fluctuations of economically harmful species known as Tetranychus urticae Koch. (Acarina: Tetranychidae), Rhodococcus perrornatus Cockerell & Parrott (Hemiptera: Coccidae), Macrosiphum rosae (L.) (Hemiptera: Aphididae), Thrips meridionalis Priesner (Thysanoptera: Thripidae), Oxythyrea cinctella Schaum, Tropinota hirta Poda (Coleoptera: Cetoniidae), Perotis chlorana Castelnau & Gory (Coleoptera: Buprestidae), Rhynchites hungaricus Herbst (Coleoptera: Attelabidae), Cnaemidophorus rhododactyla (Denis & Schiffermller) (Lepidoptera: Pterophoridae), Syrista parreyssii Spinola (Hymenoptera: Cephidae) and important natural enemies of these pests known as Anthribus fasciatus Forster (Coleoptera: Anthribidae), Adalia fasciatopunctata revelierei (Mulsant), Coccinella septempunctata (L.), Exochomus quadripustulatus (L.), Hippodamia variegata Goeze (Coleoptera: Coccinellidae) were determined. The results of this study demonstrate that R. perornatus and M. rosae are the two most economically harmful pests at the Oil-bearing rose orchards.
