Interpretive Summary:

Technical Abstract: During 2019-2022 cropping seasons, a survey was conducted in El-Behera Governorates in northern Egypt to study the occurrence, population density, host association, and distribution of phytoparasitic nematodes associated with 7 plant crops. A mixed population of 21 genera and 25 species of phytoparasitic nematodes were recovered while analyzing a total of 604 soil and root samples. The citrus nematode (Tylenchulus semipenetrans) showed 94% frequency of occurrence on the surveyed citrus trees, while the golden potato cyst nematode (Globodera rostochiensis) had a high (54%) frequency of occurrence on potato crop in El-Behera governorate. Root-knot nematodes (Meloidogyne incognita and M. javanica) with 36-62% frequency of occurrences was the most frequently encountered group of nematodes found on most of the surveyed plant crops. Criconema spp., Hemicriconemoides spp., Longidorus spp., Merlinius spp., Mesocriconema spp., Paratylenchus spp., Psilenchus spp., and Rotylenchus spp. were less common and showed low levels (8-12%) of frequency of occurrence.
