The study was conducted with the purpose of determining the population fluctuation of tomato leafminer, Tuta absoluta in Çanakkale Province in 2016-2017. The study was conducted on open field tomato in Batakovası of Central District and Delta pheromone traps were used to determine the fluctuation. Pheromone traps with E3, Z8, Z11-Tetradecatrienil were placed in plots in March, before tomato seedlings were planted, and the phenological development stages of plants were recorded throughout the study. The males of the pest were captured in the traps on 15ᵗʰ of March in 2016 and on 20ᵗʰ of March in 2017. Throughout the study, the number of T. absoluta adults was high through July, August, September and October for 4 months and the pest was present in nature for 9 months. With tomato plant development stages considered, the number of the adults caught in traps was low in seedling and pre-flowering stages, but was determined as higher in harvest season. Because the fields were not plowed after harvest season, there were adults in traps and the pest was present in nature. In open field tomato production, T. absoluta has a total of 6 generations in a year, with 5 generations in tomato production period.
