The Olive Fruit Fly (Bactrocera oleae Gmel.) is one of the most important economic pests of the olive tree which can cause very serious damages with its high population in years. This results in reduced yield and lower quality of olive oil. This paper shows the appearance and abundance of Olive Fruit Fly in the coastal area of Zadar County. The flight dynamics was monitored using a combination of yellow sticky plates type Chromotrap, ammonium salts and pheromones. This experiment was conducted during 2003 and 2004 in the period from July to October at sites Bibinje, Biograd and Ljubač. Monitoring results of fly dynamics show a certain influence of meteorological conditions (air temperature, relative humidity and precipitation) that marked that period with the seize of the adult fly population. It was found that the highest population of adult flies occurred in late September and in October, which is associated with the decrease of temperature values and the increase of relative humidity and precipitation.
