In order to identify plant–parasitic nematodes (family Tylenchidae Örley 1880) associated with Ziziphus zizyphus in Iran, 360 soil and root samples were collected from South Khorasan province during 2012–2014. Herein, a new species of Basiria several known members the family are reported. B. birjandiensis n. sp. is characterized by short body length (584–748 µm [660.6±72.3]), lip region flat apex, stylet 11–12 (11.3±0.5), excretory pore position varying isthmus level middle basal bulb (78–91...

Ektaphelenchus berbericus n. sp. was recovered from soil samples collected in eastern Iran and is described illustrated based on morphological, morphometric molecular data. The new species characterised by having female body 512-691 μ m long, lip region separated rest of a shallow depression, lips equally sized, 19-22 long stylet with wide lumen lacking knobs or swellings at its base, cuticle fine, but distinct transverse annuli three lines lateral field, excretory pore located base...

Abstract Root‐knot nematodes (RKNs) are one of the most serious pests carrot plants. Resistance cultivars a cost‐effective and ecofriendly management strategy for nematodes. To develop these, it is essential to understand genetic, molecular biochemical aspects underpinning RKN infection. Here, Meloidogyne javanica penetration development, defence reactions antioxidant enzyme activity were investigated in resistant cultivar (TN‐99‐129) compared susceptible TN‐99‐62. No significant difference...

The infectivity of three species entomopathogenic nematodes (EPNs) such as Steinernema carpocapsae Weiser (Rhabditida: Steinernematidae), Heterorhabditis bacteriophora Poinar Heterorhabditidae), and H. (IRQ.1 strain) were examined against subterranean termite Microcerotermes diversus (Silvestri) (Blattodea: Termitidae) that is the most economically destructive in Iraq. Laboratory field efficacy these strains evaluated to test feasibility indigenous EPNs be used a biological control program....

A survey was conducted in three main regions of Iraq to isolate and identify entomopathogenic insect parasitic nematodes. Soil samples were collected from 15 sites across 3 provinces grassland, date palm, citrus fields, tested for the presence Out 100 collected, 2 isolates nematodes recognized. The specimens characterized first morphologically then by molecular studies characterize based on ITS 18S rDNA genes. Both recovered soil palm orchards located city Baghdad. identified analyzing...

In order to identify the plant-parasitic nematodes associated with Berberis vulgaris, Crocus sativus, and Ziziphus zizyphus, 360 soil samples were collected from rhizosphere of these plants in South Khorasan Province Iran during 2012-2014. Among identified species, Tylenchorhynchus zeae Sethi Swarup, 1968 Telotylenchidae Siddiqi, 1960 is a new record isolate described illustrated based on morphological, morphometric, molecular characteristics. The phylogenetic tree inferred partial sequences...

Abstract The Aspergillus flavus population structure from maize kernels was examined. During 2011, samples were collected two main grain production areas in Iran (Fars and Ardebil provinces), shortly before harvest. One-hundred nine A. isolates recovered on Dichloran Rose Bengal Chloramphenicole (DRBC) agar flavus/parasiticus medium (AFPA) grouped into morphotypes Vegetative Compatibility Groups (VCGs) based morphological (e.g. sclerotia production), physiological aflatoxin-producing...

The present study was conducted to evaluate 28 commercial cultivars and two promising breeding lines of barley in terms resistance Meloidogyne javanica nematode investigate the synthesis level peroxidase, superoxide dismutase, catalase polyphenol oxidase enzymes different days after inoculation greenhouse condition. Based on results evaluation, Jolge Nimrouz were highly resistant, Rihan Zarjow very susceptible. rest ranked between these groups moderately resistant susceptible groups....

The Family Pratylenchidae comprises nematodes that are capable of penetrating and feeding on internal root tissues. list species known from Iran is presented. updated provides information their morphometrics, referring to full or partial descriptions, associated plants, geographical distribution references. includes 37 belonging five genera. Two Pratylenchus (P. sensillatus P. wescolagricus) new records for the Iranian nematofauna. Some these two other also provided.

Summary During a survey in Iran, two known species of plant-parasitic nematodes the families Tylenchidae and Criconematidae were reported for first time. The morphological morphometric characters Iranian populations recovered are discussed illustrated based on morphometrics data. population Filenchus orientalis is characterized by having 601-755μm body length, stylet length 9.0-11.3 μm, lateral field with four incisures, tail 100-118 μm males 15-21 long spicules. Hemicriconemoides...

Knowledge of the molecular changes in resistant and susceptible cultivars during nematode attack is essential for developing plant resistance. Increased expression genes related to synthesis signaling salicylic acid, jasmonic ethylene known induce defense against parasitic nematodes. Here, we inoculated approximately 3000 s-stage juveniles (J2s) Meloidogyne javanica moderately highly tomato (ALYSTE F-1 Dutch Mobil, respectively) compare developmental disease stages. The roots each cultivar...

Pistachio yield is annually reduced due to root-knot nematode infections. In order evaluate its resistance Meloidogyne javanica, three domestic pistachio rootstocks, namely, Badami, Ghazvini and Sarakhs, a wild pistachio, Baneh (Pistacia atlantica subsp. mutica), were selected. Their response the infection was evaluated based on different plant indexes, 120 days post-inoculation (dpi). The penetration development rate of in roots these four rootstocks at time points by acid fuchsin staining....
