title: Tylenchida associated with field crops in Tehran and central provinces of Iran.
abstract: On a survey of plant parasitic nematodes, belonging to the order Tylenchida, about 500 soil and root samples were collected from different field crops, such as wheat, barley, tomato, potato, corn, beets, eggplants, cuccumber, melon and also other crops cultivated in Tehran and Central Provinces during 1995-2000. All samples were washed and the nematodes were extracted by Centrifugal Flotation Technique. They were fixed and transferred to glycerin, then permanent slides were mounted. Morphological and morphometrical characters of each species were studied. In this study 31 species belonging to 17 genesa of the order Tylenchida were identified as follows. Amplimerlinius macrurus, Anguina tritici, Aphelenchoides centralis, A. limberi, A. parietinus, Aphelenchus avenae, Boleodorus thylactus, Ditylenchus dipsaci, D. destructor, D. kheirii, D. medicaginis, D. myceliophagus, Filenchus cerealis, Irantylenchus clavidorus, Helicotylenchus cavenessi, H. dehystera, H. digonicus, H. pseudodigonicus, H. pseudorobustus, Heterodera avenae, Meloidogyne incognita, M. javanica, Paratylenchus projectus, P. tateae, Pratylenchus neglectus, P. thornei, Psilenchus hilarulus, P. iranicus, Quinisulcius capitatus, Seinura oostenbrink and Zygotylenchus quevarai. The validity of Filenchus cnealis, status of Irantylenchus clavidorus and also distribution of the most economically important species were discussed.
