Volume 8 in the series, appearing in two parts, A and B, deals with the systematics of cyst nematodes of the subfamily Heteroderinae. Cyst nematodes are important pathogens causing extensive damage and significant yield loss to many crops in both temperate and tropical regions. Part A presents summarised information on various aspects of morphology, biology, ecology, pathology, biogeography, control measures and diagnostics of these nematodes. Molecular diagnostic tables and comprehensive tabular and dichotomous keys for species identification, together with descriptions of protocols for extraction, light and electron microscopy studies, and molecular diagnostics are also included. The taxonomic section of part A provides diagnoses for six genera, viz., Globodera, Punctodera, Cactodera, Dolichodera, Betulodera and Paradolichodera, and includes descriptions and morphometrics of 30 valid species. The work is illustrated by 101 drawings and photos. The genus Heterodera is mainly covered in part B, complete descriptions and morphometrics of the 80 known valid species being provided and the species illustrated by 159 line drawings and photos. Identification of the species using morphological and molecular techniques is also covered. Each part includes an extensive bibliography.

When Franklin published her book on cyst nematodes in 1951, the 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. Now a total of 105 species (including those that are considered as synonyms or species inquirende by some or all) within six genera of cyst nematodes have been described from temperate, tropical, and subtropical regions and at least five species are important constraints to crop produc tion in tropical agriculture. The previous impression of localization of cyst nematodes in the temperate region was seemingly an artifact due to a greater concentration of nematologists in the temperate regions. Based on my own experience of working in several Asian and African countries, I believe that many more undescribed species are present in the tropical countries of Asia and Africa, and probably in other tropical regions. Most growers, extension workers, and research managers in these regions are still not aware of the possible harm of presence of these nematodes in their agricultural soils. The cyst nematodes are perhaps smaller than the smallest available computer chip but they are very well programmed to survive and pro pagate despite severe hardships. These nematodes are very selective in their choice of food; about 50% of known species are parasites of plants mainly in the families Poaceae and Fabaceae.

This book is a compendium of current information on all aspects of these economically important parasites. It provides comprehensive coverage of their biology, management, morphology and diagnostics, in addition to up-to-date information on molecular aspects of taxonomy, host-parasitic relationships and resistance. Written by a team of international experts, Cyst Nematodes will be invaluable to all researchers, lecturers and students in nematology, parasitology, agriculture and agronomy, industries with an interest in chemical and biological control products for management of plant-parasitic nematodes, and any courses, quarantine and advisory services.

This book is the first complete illustrated compendium of root-knot nematode species from the genus Meloidogyne including 97 species descriptions with comprehensive diagnoses, information on biology, plant-hosts, pathogenicity, symptoms, distribution and biochemical and molecular diagnostics.

The sheath nematodes belonging to the superfamily Hemicycliophoroidea are unique amongst all plant parasitic nematodes known to man due to the presence of an extra cuticular covering or sheath over the inner cuticle and body of all juvenile and adult life stages. These plant-parasitic nematodes include species of agricultural and quarantine importance. In Systematics of the Sheath Nematodes of the Superfamily Hemicycliophoroidea John Chitambar and Sergei Subbotin provide a detailed review of the taxonomy and diagnosis of the superfamily, its member genera and 153 related species based on their morphological and molecular analyses, as well as a further understanding of the relationships within the superfamily using molecular phylogenetics. In addition, Chitambar and Subbotin also give detailed information on the global distribution, biology, host-parasite relationships and ecology of sheath nematodes.
