Fatemi E. and Charehgani H. 2018. Root lesion nematode Pratylenchus thornei. Plant Pathology Science 7(1):28-39.

Root lesion nematodes are one of the most important and fatal plant parasites. They often move between soil and host plants roots, during all stages of their life. Root lesion nematodes migrate and feed within the roots, therefore they cause necrotic lesions on the surface and throughout the cortex of infected roots. Their attack to the root can result stunting of plant root system as well as reduction in plants growth and eventually host kill. Different management methods such as the planting of resistant genotypes, crop rotation, fallow periods and use of biological control agents are successfully practiced against these nematodes. In this paper a brief discussion of economic damages, importance, taxonomy, biology and symptoms of Pratylenchus thornei attack and the most efficient management methods are presented.

Sharify Rostam-Abadi S, Rostami M,  Jahanshahi Afshar F, Ardeshir F (2023) Report of six plant parasitic nematodes from the orchards of Rafsanjan region, Kerman Province, Iran. Plant Pathology Science 12(2):41-52.
Introduction: In the suburban area of Rafsanjan city in Kerman Province, Iran, there are many orchards infested with plant parasitic nematodes. Therefore, it was necessary to identify the plant parasitic nematodes in the orchards of this region. Materials and Methods: In 2018 and 2019, some soil samples were taken around the roots of apricot, peach, pomegranate, apple, cherry and persimmon trees in this area. Nematodes were extracted by two methods, tray and sieve-centrifuge, and after fixation, they were transferred to pure glycerin. Permanent slides were examined with a bright field microscope and extracted nematodes were identified using diagnostic keys and original descriptions. Results: Seven nematodes from the infraorder Tylenchomorpha, belonging to five families including: Tylenchidae, Pratylenchidae, Tylenchulidae, Criconematidae and Anguinidae were identified. Root-lesion nematode (Pratylenchus penetrans), pin-nematode (Paratylenchus neoamblycephalus) and Criconematid (Mesocriconema xenoplax) were the most important plant parasitic nematodes in fruit orchards of this region. Conclusion: Due to the presence of some important and damaging nematodes in the orchards of Rafsanjan, it is recommended to implement appropriate management methods and monitor the population of important plant parasitic nematodes.

Abstract
Yarahmadi F, Darvishnia M, Azizi K (2023) Root-lesion and cyst nematodes of vegetable and cucurbits fields in the suburbs of Rumeshkan city, Lorestan province, Iran. Plant Pathology Science 12(2):53-65.
Introduction: Root lesions and cyst nematodes can cause serious damage and loss in vegetable and squash production. This research aimed to identify these important plant parasitic nematodes in the fields of these plants in the suburbs of Rumeshkan city, Lorestan province, Iran. Materials and Methods: Forty-five soil and root samples were collected from vegetable and squash fields in the region, in 2021. The nematodes were extracted using the tray method and fixed using the modified de Grisse method and transferred to glycerol. After the permanent microscopic slides were prepared, the morphological characteristics of each nematode were examined using a bright-field microscope equipped with a digital camera and then identified using valid keys. Results: The lesion nematodes were identified as Pratylenchus speijeri, P. neglectus and P. thornei and the cyst nematode as Heterodera schachtii. This is the first report and description of P. speijeri from Iran and also the first report of H. schachtii from lettuce in Iran. Conclusion: Due to the presence of these important plant parasitic nematodes on these plants in this region, appropriate management practices need to be implemented.
