| چکیده | ||
| نماتدهای انگل گیاهی به دلیل تعامل با گیاهان و تاثیر اقتصادی بر محصولات مختلف از مهمترین گروههای نماتدی محسوب میشوند. مطالعات فون نقش مهمی در شناسایی دقیق گونه ها ایفا می کند و پایه و اساس استراتژی های مدیریت کنترل موثر را تشکیل می دهد. برای بررسی نماتدهای انگل گیاهی در شهرستان دماوند (استان تهران)، 184 نمونه خاک از ریزوسفر محصولات مختلف باغات و مزارع طی سالهای 1401-1402 جمعآوری شد. نماتدها استخراج، تثبیت و بر روی اسلایدهای میکروسکوپی دائمی برای تجزیه و تحلیل ریختشناسی و ریختسنجی ایجاد و مورد بررسی قرار گرفتند. در مجموع 49 گونه متعلق به 23 جنس از فوق بالاخانواده Tylenchomorpha شناسایی شد. نماتدهای شناسایی شده متعلق به هشت خانواده شامل Anguinidae، Aphelenchoididae، Criconematidae، Dolichodoridae، Hoplolaimidae، Pratylenchidae، Tylenchidae و Tylenchulidae بودند. در میان این خانوادهها، Tylenchidae با فراوانی 1/17٪، گستردهترین خانواده بود که با وجود فراوانی بالای آنها، این نماتدها از لحاظ خسارت اقتصادی اهمیت چندانی ندارند. در بین نماتدهای انگل گیاهی مهم، شایع ترین گونهها در منطقه دماوند Helicotylenchus vulgaris (6 درصد) و Pratylenchus neglectus (4/5 درصد) بودند. از بین گونههای شناسایی شده، Rotylenchus elegans و Paratylenchus aciculus برای اولین بار در ایران گزارش شدهاند که در این مطالعه توصیف ریخت شناسی آنها ارائه شده است. شناسایی گونههای نماتدهای انگل گیاهی در منطقه دماوند، اطلاعات پایه و ارزشمندی برای درک پراکنش آنها و تدوین راهکارهای مدیریتی مؤثر فراهم میکند. | ||

| چکیده [English] | ||
| Plant-parasitic nematodes are among the most important groups of nematodes due to their interactions with plants and their economic consequences for a wide range of crops. Faunistic survies play a crucial role in accurate species identification, forming the foundation for effective management and 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 morphometric analysis. A total of 49 species belonging to 23 genera within the infraorder Tylenchomorpha were identified. The nematodes recovered belonged to eight families: Anguinidae, Aphelenchoididae, Criconematidae, Dolichodoridae, Hoplolaimidae, Pratylenchidae, Tylenchidae, and Tylenchulidae. Among these, Tylenchidae was the most widely distributed family, with a frequency of 17.1%. Although they were highly abundant, these nematodes are often considered to have limited direct economic crop damage potential. Among the notable plant-parasitic nematodes (PPNs), in the Damavand region, Helicotylenchus vulgaris (6%) and Pratylenchus neglectus (5.4%) were the most prevalent species. Of the identified species, Rotylenchus elegans and Paratylenchus aciculus are reported for the first time in Iran, and their morphological descriptions are provided 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. | ||
