A key based on cyst and juvenile characters is given for identification of 12 valid Heterodera species in the H. avenae group. A compendium providing the most important diagnostic characters for use in identification of species is included as a supplement to the key. Cyst characters are most useful for separating species; these include shape, color, cyst wall pattern, fenestration, vulval slit length, and the posterior cone including presence or absence of bullae and underbridge. Also useful… 
Molecular and morphological characterisation of the Heterodera avenae species complex (Tylenchida: Heteroderidae)
Morphometrical and ITS-rDNA sequence analyses revealed that the Chinese cereal cyst nematode is different from other H. avenae populations infecting cereals and is related to H. pratensis.
A reference of identification keys to plant-parasitic nematodes (Nematoda: Tylenchida\ Tylenchomorpha)
The present review has documented a list of keys for identifying plant-parasitic nematodes at different taxonomic levels including superfamily, family, subfamily, genus, and species. It was compiled
Distinguishing Heterodera filipjevi and H. avenae using polymerase chain reaction-restriction fragment length polymorphism and cyst morphology.
Using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) of internal transcribed spacer (ITS)-ribosomal (r)DNA with up to six restriction endonucleases will improve detection and identification efficiencies for cereal cyst nematodes in wheat fields.
Molecular Polymorphism and Morphometrics of Species of the Heterodera avenae Group in Syria and Turkey.
The results showed a clear separation of the three cyst nematode species on cereal using a conventional method for classification and molecular tests, and confirmed the congruence between genetics and morphological traits.
Characterization of cereal cyst nematodes (Heterodera spp.) in Morocco based on morphology, morphometrics and rDNA-ITS sequence analysisis
Morphological and molecular diversity among 11 populations of cereal cyst nematodes from different wheat production areas in Morocco was investigated using light microscopy, species-specific primers,
Morphological and molecular identification of cyst nematode species (Heterodera spp.) in Algerian cereal fields
The results of this study are of great value to breeding programs and extension services, where they will contribute to the design of control measures to keep damaging nematodes in check.
Species-Specific PCR Assays for Differentiating Heterodera filipjevi and H. avenae.
This is the first report of a species-specific ITS PCR assay to detect and identify H. filipjevi and H. avenae, which will enhance diagnosis of cereal cyst nematode species in infested fields.
Nematodes which Challenge Global Wheat Production
Effects of cereal cyst (Heterodera) and rootlesion (Pratylenchus) nematodes on wheat are difficult to identify and control, and molecular markers have been developed to identify genes and quantitative trait loci for resistance in seedlings.
Morphological and molecular characterisation of Heterodera filipjevi (Madzhidov, 1981) from the Slovak Republic
The results of the phylogenetic analysis of the ITS rRNA gene sequences confirmed the species identification and phylogenetic relationship of H. filipjevi with other Heterodera species and showed the close similarity between the Slovakian and Chinese samples, which differed by a single nucleotide and clustered together.


An illustrated key to the cyst-forming genera and species of heteroderidae in the Western hemisphere with species morphometrics and distribution.
Diagnoses of the cyst-forming genera of Heteroderidae and distribution and morphometrics of the 34 known cyst species in the Western Hemisphere are presented along with an illustrated key for the identification of these genera and species.
Heterodera aucklandica sp. n. (Nematoda: Heteroderidae) from a New Zealand native grass, with notes on the species of the H. avenae group
Heterodera aucklandica is described from the New Zealand native grass Microlaena stipoides, a cyst nematode species belongs to the H. avenae group, a heterogeneous group of species characterised by a vulval slit length in the range 4.5–20 μm.
Heterodera pratensis sp. n., a new cyst nematode of the H. avenae complex (Nematoda: Heteroderidae).
A new cyst-forming nematode belonging to the Heterodera avenae complex and specialized on grass hosts is described as H. pratensis sp. n. The species is widely distributed in grassy habitats in
Compendium of Cyst Nematodes in the U.S.S.R
Data on distribution of 37 cyst nematodes of the genera Heterodera, Globodera and Punctodera known in the U.S.S.R. are reviewed including short descriptions, diagnoses and comments on 21 species
Some Problems Posed by the Heterodera avenae Complex1
Application of a multivariate technique, principal co-ordinate analysis, to second-stage juvenile characters indicates that H. avercae pathotype 3 is as distinct from H. avenae as H. arenaria, an accepted species in the Heterodera avenae group.
Morphology and Identification of Cyst Nematodes
Whatever their origin, host, or economic status, accurate identification of cyst nematodes is of paramount importance for any decision making process.
Phylogenetic classification of the family Heteroderidae (Nematoda: Tylenchida)
The family Heteroderidae, its six subfamilies and 17 genera are defined or redefined, and for each of the genera the nominal species and their synonyms are listed.
A redescription of Heterodera arenaria Cooper 1955, a cyst nematode from marram grass
Sununary Helerodera arenana Cooper, 1955 is redescribed from marram grass (Ammophila arenana) from Gibraltar Point, Eastern England. The same species was also found on marram grass from seven other
Morphology of the Terminal Areas of White Females and Cysts of the Genus Heterodera (s.g. Globodera).
Using a scanning electron microscope and an interference contrast microscope, distinct morphological differences were found in the terminal areas of white females and cysts of six species of the
Heterodera spinicauda sp. n. (Nematoda: Heteroderidae) from mud flats in the Netherlands, with a key to the species of the H. avenae group
This new Heterodera species, with its bifenestrate vulval region and short vulval slit, belongs to the H. avenae group and is unique because of: an inconspicuous vulval cone, giving the initial impression that the cysts are spherical.
