Tylenchida


Book Description

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.




Functional and detailed Morphology of the Tylenchida (Nematoda)


Book Description

This is the first and so far the one and only treatise on the morphology of the Tylenchs. Tylenchs are economically important Nematodes that live in huge numbers in the soil. They are microscopic and they show a constant number of cells, a characteristic in Nematodes. The cell count in Tylenchs, undertaken here for the first time, resulted in an estimate of fewer than a thousand cells. All the different cell types are described in great detail, and some of them are rather unusual in the Animal Kingdom. The internal pressure system (typical for Nematodes) in conjunction with the presence of a hollow stylet (typical for Tylenchs), results in rigorous but functional relations among the several body parts. Throughout the book functional morphology is a key topic and an entire chapter is devoted to it. The book is amply illustrated with line drawings that are based on microscopic and sub-microscopic observations.




The Plant-Parasitic Nematode Genus Meloidogyne Göldi, 1892 (Tylenchida) in Europe


Book Description

The genus Meloidogyne Göldi, 1892, or root-knot nematodes, represent a relatively small but economically important group of obligate plant pathogens. They are distributed worldwide and parasitize on almost every higher plant species. While reproducing and feeding within roots, they induce galls or root-knots and disorder the physiology of the infected plant, reducing crop yield and product quality. More than eighty nominal species have been described worldwide, while twenty species have been detected in Europe so far. This book includes a historical review on the genus, followed by a revision of the European species, and completed with a study on one of the most characteristic morphological structures within the genus: the perineal pattern.

The Agronomy and Economy of Turmeric and Ginger


Book Description

Turmeric has been used as a medicine, a condiment, and a dye since at least 600 B.C., while ginger has been used extensively throughout history for its medicinal purposes. The Agronomy and Economy of Turmeric and Ginger brings these two important plants together in one reference book, explaining their history, production techniques, and nutritional and medicinal properties in detail. This book is intuitively organized by plant and use, allowing quick access to information. It puts the uniquely Indian use and history of turmeric and ginger plants into a global context of production and economic aspects. It explores the plants from a botanical perspective, and goes into details of their chemical composition as well. Rounding out the book are chapters on disease and pest control issues. The book is a valuable resource for those involved in the production and marketing of these plants, as well as those looking for more information on the medicinal and nutritional properties of turmeric and ginger. - The first book to bring together extensive information about turmeric and ginger - Incorporates medicinal, nutritional and agricultural aspects of the two plants - Offers a global perspective




Turmeric (Curcuma longa L.) and Ginger (Zingiber officinale Rosc.) - World's Invaluable Medicinal Spices


Book Description

This book discusses the various aspects, from production to marketing of turmeric and ginger, the world’s two most important and invaluable medicinal spice crops. The book begins with their origin and history, global spread, and goes on to describe the botany, production agronomy, fertilizer practices, pest management, post-harvest technology, pharmacology and nutraceutical uses. The book presents the economy, import-export and world markets involved with reference to turmeric and ginger. It would be a benchmark and an important reference source for scientists, students, both undergraduate and post graduate, studying agriculture and food sciences and policy makers. It would be of great interest to professionals and industry involved in spice trade.




Criconematina (Nematoda: Tylenchida)


Book Description

Criconematina are nematodes, or unsegmented roundworms, belonging to the group Tylenchida. Tylenchids are plant parasitic nematodes with a hardened mouth piece which they use to puncture plant cells, and many tylenchids cause damage to agricultural crops. This is especially true in monocultures where their population numbers can build up to high levels when favoured crops are replanted in quick succession. Criconematina are microscopic and transparent nematodes, generally feeding on tree roots. Their damage is restricted to commercial orchards planted with infested plant material or replanted in infested soil. In their native habitat they generally cause no damage. There are 68 species of criconematids known to be present in New Zealand, and 47 of these are endemic. This fauna covers all 68 species, 16 of which are new to science, and includes detailed descriptions for the female of each species, including morphometrics and illustrations, supplemented by SEM micrographs of morphological details. Details of males and juveniles are given if available. A diagnosis is presented to distinguish each species from other New Zealand species.Locations and plant species associations of each species are indicated and the significance of each species as a taxonomic unit is commented upon. Lists of nematode species present at various localities and associated with individual plant species are given in appendices, and keys to all taxa covered are provided."




Plant Parasitic Nematodes


Book Description

Plant Parasitic Nematodes, Volume III provides a comprehensive discussion of the different advances in plant nematology. This includes biochemical techniques to taxonomy and innovation in transmission and scanning electron microscopy technology. It explains a broadened basis for understanding nematode physiology and behavior and the sensory mechanisms that govern nematode actions and plant host-nematode interactions. The book discusses the development of modern approaches to the evaluation and reduction of crop losses. The emphasis of this volume is on plant parasites and insights gained through research on other nematodes. In particular, the book explains the anatomical, developmental, behavioral, and genetic studies on the free-living nematode Cenorhabditis elegans, which is a widely used laboratory model for examining various biological problems. The information provided by various researches on C. elegans increases our understanding about the relevance of nematodes to general biological processes in higher organisms, including man. The book is divided into 19 chapters which cover the following concepts of plant nematology: biochemistry, cytochemistry, and genetics; morphology and function; host-parasite relations; and evaluation and control of crop losses. The present volume is an excellent reference for students, lecturers, and research professionals in plant parasitology and related fields.







Catalog of the Order Tylenchida (Nematoda)


Book Description

This guide provides a consolidated list of nematode taxa for the order Tylenchida, which includes most of the plant parasitic nematodes pertinent to worldwide agriculture. Within each family, the type genus is first considered, then other genera are listed alphabetically. Species are similarly listed for each genus. Where applicable, species inquirendae are indicated. Nomina nuda are not included in the text as these are not taxonomically available. The Alphelenchina is organized along similar grounds but all subfamilies were excluded. The guide includes all available taxa to June 1, 1991.
