The study of the population and flight activity of the olive fruit fly using-pheromone and water traps showed five periods of flight activity. The first two small peaks were between mid-March and mid-April, and between mid-June and early July. The third peak occurred between mid-August and mid-September, the fourth peak in early October and the fifth peak between end October and mid-November. The greatest number of males caught was between mid-July and mid-November, while the greatest number of males and females caught by both sex-pheromone and water traps was in October. The number of adults caught at the inner phase of the sex-pheromone trap was more than the outer phase in all periods, except from early September up to mid-October, when the caught numbers in both phases were generally similar. The number of adults caught by water trap was generally less than those in the pheromone trap. The number caught by the water at 0.5 m was twice more than that at the 1.5 m and 3.20 m from the trunk tree in all months of the trapped period
