Determining the Population Fluctuation of the Mediterranean Fruit Fly, Ceratitis capitata (Wiedemann, 1824), in Some Fruit Orchards in Bayramiç (Çanakkale)

This study was conducted in 2021-2022 in the Bayramiç district of Çanakkale province to determine the population development of the Mediterranean fruit fly [Ceratitis capitata (Wiedemann, 1824)] in quince, Bayramiç beyazı (nectarine), apple, fig, cherry, peach, and persimmon orchards. In the selected orchards, one McPhail and delta-type pheromone trap were installed. Additionally, 100 fruits were randomly inspected in the orchards to determine the damage rate. The first adult flights were detected in a peach orchard on August 2, 2021, when the total effective temperature was 1255 degree-days. The following year, on July 29, the first adult flights were observed with a total effective temperature of 1146 degree-days. The highest number of adult individuals in the traps was recorded on November 8, 2021, with 486 individuals (adult/2traps) in a persimmon orchard. Additionally, Bayramiç beyazı was identified as a new host for the pest. The study found the damage rates in the orchards where C. capitata was detected as follows: 15.6% in the persimmon orchard, 14% in the peach orchard, 8.6% in the Bayramiç white orchard, and 6.1% in the quince orchard.
