The study was conducted in eight different peach orchards in central, lapseki and bayramiç districts of canakkale province. the adult population change of oriental fruit moth, grapholita molesta busck, was studied using pheromone traps. the species g. molesta was abundant in all sampling orchards between 2008 and 2009. the emergence of adults started from middle of april through november in both years. there was positive correlation between daily average temperature and the number of adults caught in the traps. four to five flight periods were observed, throughout the season, in april, june, july, august and october. the adult population development curves suggest that the pest has four to five generations per year depending on the daily temperatures in early spring. we concluded that late cultivars would be more vulnerable to the pest because of the high number of adult moths in august and september.
