The increasing use of integrated crop management often requiring a reduction in the reliance upon chemical control means that the need to rapidly identify pest nematodes has never been greater. This second edition of this standard reference work familiar to all plant nematologists is therefore even more useful than its predecessor published in 1986. The in-depth description of the life histories of the genera of the Tylenchida have been retained and brought up-to-date through the inclusion of all the research carried out between the publication of the last edition and this new edition. This expanded edition includes detailed diagnoses of well over 200 genera and familial and ordinal groups and is well-illustrated with drawings of type or representative species. These together with comprehensive lists of species and genera and their synonymies provide the foundation for the status and validation of each taxon within the Tylenchida. A considerable amount of information is provided regarding the biology ecology and pathogenicity of these parasites. Language: English
