- Abstract
The olive fruit fly Bactrocera oleae (Rossi, 1790) (Diptera, Tephritidae) is one of the most important and most dangerous insect pests of olives in the Mediterranean region including Syria. The population dynamics of the olive fruit fly was studied at three different geographical locations in Tartous Governorate with an average of three fields in each location (Almtahrea, Safita, Sindyanat Obin) during the years 2016 and 2017, using food traps (McVille) containing protein hydrolysates (1-3%) as an attractive material for olive fruit fly. The traps were placed in May of each year and remained until the end of the season, and readings were made weekly. Peaks of insects captured varied between 4 to 5 according to location and season. The highest value of the olive fruit fly population density was 80.5±58.22 insect/trap/week on 17/10/2016 at the Sindianat Obin location in 2016 and was 18.56±16.28 insect/trap/week on 29/10/2017 in 2017. In Safita location, the highest insect population density was 34.11±33.13 insect/trap/week on 10/10/2016, and the population density decreased in the following year and the highest population density was 13.89±6.62 insect/ trap/week recorded on 5/11/2017. The density of the insect was low in general at the Almtahrea location during the two years, with the highest population density of 7.67±3.28 insects/trap/week on 12/06/2016 and 7.11±1.39 insect/trap/week on 22/10/2017. The correlation between weekly population density of adult olive fruit fly was positive with the average humidity levels and negative with the average temperature. A very positive correlation was also observed between the average population density of adult olive fruit fly and altitude above sea level.
