Technical Abstract: A preliminary survey of plant-parasitic nematodes associated with olive was performed in Al-Jouf region, north Saudi Arabia. Olive is a newly introduced crop in this region, and is cultivated in the agricultural enterprises of some of the biggest Saudi agricultural companies. Seedlings are mostly imported from Syria, Italy and Spain. The dominant cultivars are Arbequina, Arbosana, Cornicabra, Manzanillo, Nepali, Picual and Sorani. A total of 216 soil and root samples were collected, and nematodes were extracted using a centrifugal flotation method. Nematodes were identified based on the morphological features. Additional nematode samples were kept in 2% formalin and/or DESS solution, and were sent for further identification at the USDA ARS Nematology Laboratory, Beltsville, MD, USA. A total of nine nematode genera were identified. These nematode genera/species include: Aphelenchoides sp., Aphelenchus sp., Ditylenchus sp., Helicotylenchus digonicus, H. pseudorobustus, Meloidogyne javanica, Paratylenchus nainianus, Pratylenchus vulnus, Tylenchorhynchus goffarti, and Tylenchus sp. These nematode species are recorded in the rhizosphere of olive for the first time in Saudi Arabia.
