Abstract

The Olive moth, Prays oleae (Bern) is the most abundant pest of olive trees throughout the Mediterranean and the Black Sea, the Middle East and Canary Islands. The damage caused by this insect can reduce the olive production by 49 to 63%. Yellow sticky traps were preferred to monitor the population of Olive moth. For this purpose, to determine the population dynamics of adult Olive moth, 6 yellow sticky traps were placed haphazardly within the tree canopies (approximately 1.5 m in height) of each olive grove between the months of July and December during 2015 and 2016 in Güzelyurt and Girne regions where olive growing is intensely cultivated and traps were positioned on the southern side of each tree. The traps were renewed every week on same day periodically. In Güzelyurt region, the highest population rate was found in Lefke on 2015 and in Doğancı on 2016. In Girne region, the highest population was found during October in Zeytinlik village on 2015. On 2016, the highest population was observed during August in Karakum village. Basically, the reason for the high population was the application time of chemicals in the first and second generations of Olive moth. During this study, the effective management method against the Olive moth was observed determination the correct period of insecticide application.
