Abstract

ABSTRACT

ABSTRACT

Plant-parasitic nematodes are among the most important nematode groups due to their interactions with plants and their economic impact on various crops. Faunistic studies play a crucial role in accurate species identification, forming the foundation for effective management control strategies. To investigate plant-parasitic nematodes in Damavand County (Tehran Province), 184 soil samples were collected from the rhizosphere of various crops in orchards and fields during 2021-2022. Nematodes were extracted, fixed, and mounted on permanent microscopic slides for morphological and morphometrical analysis. A total of 49 species belonging to 23 genera within the infraorder Tylenchomorpha were identified. The recovered nematodes belong to eight families were including: Anguinidae, Aphelenchoididae, Criconematidae, Dolichodoridae, Hoplolaimidae, Pratylenchidae, Tylenchidae, and Tylenchulidae. Among these, Tylenchidae was the most widely distributed family, with a frequency of 17.1%. Despite their high abundance, these nematodes are often considered non-significant regarding economic crop damage potential. Between important plant-parasitic nematodes (PPNs), the most prevalent species in the Damavand region were Helicotylenchus vulgaris (6%) and Pratylenchus neglectus (5.4%). Among the identified species, Rotylenchus elegans and Paratylenchus aciculus are reported for the first time in Iran, and their morphological descriptions are given in this study. The identification of plant-parasitic nematode species in the Damavand region provides valuable baseline information for understanding their distribution and for developing effective management strategies.
