This research aimed to investigate the prevalence of olive fruit midge Prolasioptera berlesiana and its relation to both the olive fruit fly Bactrocera oleae (Gmel.) and the olive rot diseaseCamarosporium dalmaticum (Thüm.) and its population dynamics. Field survey was carried out on olive groves in Lattakia over the seasons 2015 and 2016. The results revealed presence of olive fruit midge correlated with the olive fly and olive rot disease on all survey sites. The highest percentage of fruits containing the predator was recorded in Qardaha22.5٪   while   it was 20٪   and 17.33٪  in Al-Haffah and Jableh respectively in 2016. In addition, the results showed that the olive fruit midge has three-generation compatible with the olive fruit fly generations, tow generations in the Sumer and  one in  the Fall.
