| Abstract | ||
| A survey study was conducted to identify the current status of the plant nematode community associated with growing trees in northwestern of Egypt. About 1839 soil and root samples were collected, during the period from 2021 to 2022 at the entire costal districts besides the Siwa district of Marsa Matrouh governorate. Root- knot nematode, Meloidogyne spp < em>. was the most abundant and dominant genus in all nine surveyed regions viz., Al Hammam, Al Alameen, El Moghra,Al Daba, Matrouh, Al Nigela, Sidi Barrani, Al Salloum, andSiwa. Results showed that 12 plant parasitic nematodes (PPNs) genera were recovered from all locations and identified as; Criconema, Hoplolaimus, Helicotylenchus, Meloidogyne, Rotylenchulus, Pratylenchus, Pratylenchus, Tetylenchus, Trichodorus, Tylenchorhynchus, Tylenchus and Xiphinema. Nematode genera were more diverse in Siwa district than others, since it possessed 10 genera (all recorded genera except Pratylenchus, Pratylenchus). The density of PPNs was affected with soil type as the fine sand texture favored nematode population, soil pH not greatly influenced nematode reproduction, but the host type significantly affects nematode population.Also, this study will pay the attention to consider nematode occurrence to prevent contamination of new reclaimed farms as well as manage their population in infested fields in these desert areas.
