Abstract

In order to identify the plant-parasitic nematodes associated with medicinal plants in Boyer-Ahmad region, Iran, 84 soil and root samples were collected during 2015-2016. The nematodes were extracted from soil samples, according to the sieving-centrifugal flotation method, and then fixed and transferred to glycerin according to the modified De Grisse’s method. Identification of the nematodes insides the roots was also done with the Hooper’s staining technique. After microscopic observations of the permanent slides, the necessary measurements were made. Finally, the extracted nematodes were identified at species level using available diagnostic keys. In this study, 28 species belong to 14 genera were identified as follow:
Amplimerlinius globigerus, Aphelenchoides cyrtus, A. haguei, A. varicaudatus, Helicotylenchus digitiformis, H. digonicus, H. exallus, H. pseudorobustus, H. varicaudatus, H. vulgaris, Longidorus africanus, Meloidogyne hapla, M. javanica, Merlinius brevidens, Mesocriconema antipolitanum, M. lobellum, Nagelus obscurus, Pratylenchoides ritteri, Pratylenchus cruciferus, P. curvicauda, P. delattrei, P. neglectus, P. sefaensis, P. sudanensis, P. thornei, Rotylenchus cypriensis, Scutylenchus rugosus, Xiphinema pachtaicum, Zygotylenchus guevarai.
Mesocriconema lobellum and Pratylenchus sudanensis were recovered from the rhizosphere of marsh-mallow and horehound plants, respectively and are reported for the first time from Iran here.
