Investigations were undertaken in to estimate yield losses of carrot, sugarbeet, wheat, and potato caused by cyst-forming nematodes (Heterodera and Globodera species) in several provinces of Italy. Soil samples were collected at planting in ha sampling areas distributed in each crop's major production area. Yield loss estimates were based on nematode population estimates and on. Among the species identified, Meloidogyne sp., R. similis, and P. coffeae are the ones which are economically important (Ayyar, ).The root knot nematode Heterodera radicicola (Greef) Muller was first reported on turmeric by Ayyar ().Two species of root knot nematodes, namely M. incognita (Kofoid & White, ) Chitwood and M. javanica (Treub, ) Chitwood, , have been.
HETERODERA ROSII (HETERODERIDAE), A NEW SPECIES OF CYST-FORMING NEMATODE FROM CURLED DOCK (Rumex crispus L.) J. J. Duggan An Foras Taluntais, Nematology Department, Kinsealy, Malahide, Co. Dublin P. A. Brennan Agricultural Zoology Department, University College, Dublin ABSTRACT Hererodera rosii n. sp. is described and illustrated. Additional differentiation between species using biological tests on suitable host plants may be useful, but can take 6–8 weeks. Cysts of H. glycines can be differentiated from other Heterodera species by polyacrylamide gel electrophoresis of the enzyme .

Although there has been a considerable amount of research on various aspects of the biology and control of economically important cyst-forming species of Heterodera, publications have so far remained widely scattered.
The comparatively recent splitting of the species H. schachin, however, formed a stimulus for the collation of literature, resulting in the present review of most of the published Cited by: The cyst-forming species of Heterodera. [Mary T Franklin] Home. WorldCat Home About WorldCat Help. Search.

Heterodera is a genus of nematodes in the family s of the genus are obligate parasites and different species attack different crops, often causing great economic damage.
The genus is unique among nematode genera because of the ability of the female to transform into a tough, brown, cyst which protects the eggs which have been formed within her : Secernentea. The cyst-forming eelworms are to-day giving rise to wide-spread anxiety on account of the serious economic losses they are causing, especially to growers of potatoes, sugar-beet, brassicas, cereals and other major food crops.
In this authoritative manual, Dr. Mary T. Franklin describes the morphological characteristics, diagnosis and life histories of the various species, the role of weeds in Cited by: A new species of cyst-forming nematode, Cactodera solani n.
sp., from Mexico is described. The new species was found in a glasshouse in Mexico City parasitising tomato and common lambsquarter. This cyst nematode has light brown to almost black cysts, presents a small vulval cone with circumfenestra and morphologically it most resembles C.

Detailed examination of the cysts of 39 of the 53 described species of Heterodera, a cyst-forming nematode, was undertaken to provide an adequate basis for identification of these mic keys, based on information gained from studies of cone top and terminal areas of the cyst, are presented.

When Franklin () published her book on “The cyst-forming species of Heterodera”, cyst nematodes were already a major concern and were known to cause serious yield losses in important food crops such as potatoes, cereals, brassicas, tomatoes and sugar beet.
When Franklin () published her book on “The cyst-forming species of Heterodera”, cyst nematodes were already a major concern and were known. The carrot cyst nematode Heterodera carotae is a highly specialized parasite infecting only wild and cultivated carrots (Daucus carota L.) and an herbaceous plant known as the hedge parsley (Torilis leptophylla L.) (Jones, b; Mugniery and Bossis, ).This nematode might cause serious problem in the carrot growing areas in Italy leading to yield loss around 20% to 90% in carrots (Greco.
An account is given of observations made between and on beet eelworm and related species of Heterodera. The host ranges of beet‐, potato‐, pea‐, carrot‐ and Galeopsis‐root eelworms were studied in the field, on sites where previous information had been obtained of the species of Heterodera present.

ELIA 1 Abstract: Investigations were undertaken in to estimate yield losses of carrot, sugarbeet, wheat, and potato caused by cyst-forming nematodes (Heterodera and Globodera species) in.
Diagnoses of the cyst-forming genera of Heteroderidae (viz., Heterodera, Sarisodera, Globodera, Punctodera, Cactodera, and Dolichodera) 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 key is based mainly on cysts and larvae, and important morphological.
Abstract. Cereals and grasses are damaged by several species of cyst forming nematodes. One species, Heterodera avenae Woll. (the oat nematode = cereal root eelworm), is common in countries in Northwest Europe, and is found in Canada, North Africa, India and Australia. Heterodera sp.; some of these may correspond to new -one new sequences from Iranian cyst-formingnematodes and 36 known sequences were used for the phylogenetic analyses.
The cyst-forming nematodes formed several clades correspondingto. This book is an in-depth study of plant nematodes and discusses agrotechnical, physical, and chemical measures for the control of parasitic nematodes.
The most harmful pests (cyst-forming, gall, stem, and other nematodes) are described individually. In addition, contemporary methods for the study of nematodes are detailed. A comprehensive bibliography is included.5/5(1). The genera Heterodera and Globodera have comprised the most economically important species of the cyst nematode for several decades.
When Franklin published her book on “The cyst-forming species of Heterodera” inthe cyst nematodes were already a major concern and. Bymore than 40 species of the genus Heterodera had been molecularly characterized by sequencing the ITS-rRNA genes and by PCR-RFLP profiles.
These tools are so far the best available for identifying cyst-forming nematodes. By restricting the lTS amplicons with one or a combination of seven restrietion enzymes (AIuI, Aval, BshBsuRI, C/ol, MvaI, and Rsal), h most of the.
Abstract. The internal transcribed spacer 2 (ITS2) of the ribosomal RNA gene is a double-edged tool for eukaryote evolutionary comparison. In this paper, we re-evaluate the putative ITS2 secondary structures proposed for 29 species of cyst-forming nematodes in the genus Heterodera.
The plant-parasitic cyst-forming nematodes of the genus Heterodera Schmidt, (Heteroderidae, Tylenchida) comprise more than 60 species parasitizing herbaceous and woody plants. Some species are considered as highly pathogenic and as important nematode pests to cereals, legumes, sugar beet, cabbage, carrot, and other crops (Baldwin and Mundo.
A new species of the genus Heterodera A. Schmidt, parasitic on river birch, Betula nigra L., is described and illustrated.
Females and cysts are lemon-shaped to almost spherical with slight vulval protrusion. Female cuticles have a thick subcrystalline layer. The average cyst size is by [mu].Nematode diseases caused by Hirschmanniella spp.
are becoming a major threat to lotus production in Tokushima Prefecture, a primary production area in Japan. The objectives of this study were: i) to design specific primers to Hirschmanniella spp. causing damage to lotus; ii) to evaluate the relationship between pre-plant density of Hirschmanniella spp.
in soil and damage index of lotus; and.When Franklin published her book on cyst nematodes inthe cyst nematodes were already known as serious pests of brassicas, cereals, potatoes and sugar beets. However, at that time this group of nematode, with about 12 species, was considered tobe largely temperate in distribu tion.
