The fruit cultivation is very important for Turkey export. Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is an important pest of many fruit and vegetables. For this reason, the population of C. capitata was followed on three fruit orchard during 2013-2015. Studies have been carried out at avocado, peach and fig orchards by McPhail type trap which contain trimedlure feromone capsule. In the result of study, the highest population of C. capitata was determined on avocado orchard on October 2013 (499 adult/trap). C. capitata adults were obtained by the culturing of the sturdy-looking fruits from the avocado trees, under laboratory condition; however, flesh flies members had been obtained when fruits which were fallen of the ground and became decayed were collected. Although the first individuals were caught in the peach orchard at the beginning of May, the infected fruit were observed in the middle of June, at the remaining fruit on tree after harvesting. Mediterranean fruit fly did not constitute as a threat for early peach varieties which harvesting started at the beginning of May in the Çukurova Region, but it is threat for late maturing varieties, which was harvesting time started at middle of the June. Although first individuals were caught at the beginning of May, the highest population was observed within August (297 adult/trap), flight activity of C. capitata has been sustained untill end of October. In contrast to other fruit trees, fig trees do not fail its fruit which is infested with C. capitata and, Pycnonotus xanthopgos Hemprich & Ehrenberg (Pycnonotidae: Passeriformes) and Vespula spp. (Hymenoptera: Vespidae) become predators of the larvae in the infested fruit were observed.
