Abstract: The plant-parasitic nematodes Meloidogyne spp. were first reported on tomato plants in 1957 in the Eastern region of Saudi Arabia. Since then, many other plant parasitic nematodes have been reported causing serious losses to many economically important agricultural crops. Until now, several efforts have been made to control these nematodes either in the greenhouse or in the open fields. To achieve a successful control of theses nematodes, comprehensive nematological surveys must be carried out to determine the abundance and the economic importance of the plant-parasitic nematodes. Thus, a total of 30 nematode genera have been reported to be associated with different plant species all over the kingdom. We have classified these genera into three major groups according to their economic importance. The first group included the genera of the highest prevalence and economic impact (e.g. Meloidogyne spp., Heterodera avenae and Tylenchulus semipenetrans). The second group included those genera that have a relatively medium importance and prevalence (e.g. Pratylenchus spp., Tylenchorhynchus spp., Helicotylenchus spp., Trichodorus spp., Criconemella spp., Longidorus spp., Xiphenema spp., Hopolaimus spp., Paratylenchus spp., Hemicycliophora spp. and Ditylenchus spp). While the third group included the nematodes of the least prevalence and economic importance. We believe this information would be of great importance to lay out meaningful control strategies.
