Abstract: 

This research was conducted during the period (2017 – 2021), in accordance with decision No. 488/16/16/2017 issued by the Minister of Agriculture and Agrarian Reform, which includes the formation of a committee, whose task is to prepare a map of the region of the spread of diseases and insects that affect olive trees, maps of environmental factors and areas suitable for olive spread, and the map of convenient olive varieties in Syria, based on GIS programs. According to the steps of preparing the maps and representing the required data, data related to the dominant variety and the most important pests spread by altitude were collected and verified during the field tours of the work team in Aleppo Governorate, and detection of the accuracy of the results with the concerned departments in the Directorate of Agriculture, and accordingly, the required maps were completed in the two governorates. The implemented GIS maps showed clarity in the extrapolation and analysis of some information about the governorates of Aleppo and Idleb, such as the altitude above sea level, minimum and maximum temperatures, which showed the topographic and climatic diversity of the two governorates, and the environmental resilience of the prevalent varieties of olive that dominates most of the cultivated areas there. The spread of pests that affect the olive tree was associated with the variety and its sensitivity sometimes, such as infestation by the stalk borer, and with climatic conditions at other times, such as the spread of the peacock’s eye disease in wet areas and near-surface water, and the maps showed also that the dominant varieties in Aleppo governorate are Zayti, Sourani and Qaisi, while the Sourani variety spread in most areas of Idleb governorate.

Keywords: olive, GIS maps, probability pests, dominant variety.
