Abstract


This study was carried out at the coastal area in Syria, to determine the geographic distribution of fig stem borer Batocera rufomaculata, infestation, host suscepility and the human factor for dispersal of the borer, The results showed that the borer is presented in all the locations and The infestation ranged from 70.2% to 85.34%. The mortality of trees was the highest in the Thorah- nursery (47.61%) and just 13.3% in Wadi-alshater location. Our findings demonstrated that, the number of dead tress with diameter more than 20cm increased significantly toward that tress with less diameter. The results accounted that, the human factor had a big role to dispersal of the borer, wherever no control managements against the pest were used. Our results indicated that, B. rufomaculata was the main reason for reduce of fig production, therefore further researches are required to find the best ways to control this destructive pest.
