This book was released on 1995-11-30 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family Trichodoridae was established by Thorne in 1935 but it remained of limited taxonomie interest until 1951 when Christie and Perry associated Trichodorus christie (now Paratrichodorus minor) with a "stubby root disease" that affected certain crops in Florida, USA and interest further increased from 1960 when P. pachydermus was implicated as a vector of the economically important tobacco raule virus. Such discoveries gave an impetus to studies on many aspects of the biology of trichodorid nematodes with a consequent proliferation of new species described from different parts of the world. The number of species increased from twelve in 1957 to a present day total exceeding eighty. This rapid expansion in the number of species was accompanied by several reappraisals of the taxonomy and systematies of the family, the most notable changes being the creation of the genus Paratrichodorus by Siddiqi in 1974 and the recognition of the monodelphic genera Monotrichodorus and Allotrichodorus respectively by Andrassy in 1976 and Rodriguez-M, Sher and Siddiqi in 1978. Reliable and unambiguous identification of taxa is dependent on the known reliability of a range of characters, whieh remains of paramount importance in taxonomy even when biochemical and molecular methodology is available. In this book each of the species, including synonyms and species inquirenda, that comprise the family Trichodoridae is re-described from meticulous mieroscopie examination of type specimens, material from official nematode collections and populations in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Although nematodes had long been suspected as vectors of soil borne plant diseases, unequivocal proof of their implication was not forthcoming until 1958 when Professor William Hewitt and his colleagues in California demonstrated experimentally that Xiphinema ~ was the vector of grapevine fanleaf virus. This opened up a new and exciting field in plant pathology and discoveries quickly followed of other nematode species associated with soil-borne diseases of many different crops and in several countries. After the initial enthusiasm of discovering new vectors and new viruses there followed a period of consolidation in which research workers sought answers to tantalising questions about the location of the virus within the nematode, the factors governing the close speci ficity between virus and vector; and more mundane but equally important and compelling questions about life cycles, geographical distribution, host relations, morphology and taxonomy. No other group of nematodes has attracted such a concentrated effort involv ing many different scientific specialisations and yielding so much progress in a relatively short time. The NATO Advanced Study Institute held at Riva dei Tessali, Italy, during 19 May to 2 June, 1974, provided the forum for a critical discussion of all aspects of biology of virus vector nema todes.
Download or read book Plant Parasitic Nematodes written by Bert Zuckerman and published by Elsevier. This book was released on 2012-12-02 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Nematoda written by Andreas Schmidt-Rhaesa and published by Walter de Gruyter. This book was released on 2013-12-18 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.

Download or read book Plant Parasitic Nematodes in Sustainable Agriculture of North America written by Sergei A. Subbotin and published by Springer. This book was released on 2018-12-17 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are recognized as one of the greatest threats to crop production throughout the world. Estimated annual crop losses of $8 billion in the United States and $78 billion worldwide are attributed to plant parasitic nematodes. Plant parasitic nematodes not only cause damage individually but form disease-complexes with other microorganisms thereby increasing crop loss. Nematode diseases of crops are difficult to control because of their insidious nature and lack of specific diagnostic symptoms which closely resemble those caused by other plant pathogens and abiotic diseases. Future developments of sustainable management systems for preventing major economical agricultural losses due to nematodes is focused on strategies that limit production costs, enhance crop yields, and protect the environment. This book presents a first compendium and overview for nematode problems and their management across North America. Each chapter provides essential information on the occurrence and distribution of plant parasitic nematodes, their major crop hosts, impact on crop production and sustainable management strategies for each region of the continent including, Canada, Mexico and all states of the USA. For each region, a thematic overview of changes in crop production affected by plant parasitic nematodes and their management strategies over time will provide invaluable information on the important role of plant parasitic nematodes in sustainable agriculture.

Download or read book Dorylaimida written by M. Shamim Jairajpuri and published by BRILL. This book was released on 2023-11-27 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dorylaimida represent a large and very important group of soil and freshwater inhabiting nematodes of great agricultural importance. Both in appearance and mode of life they represent a wide diversity and as a consequence the number of species and higher taxa that have been described hitherto is the highest within Nematoda. The identification of species, genera, families, etc. of Dorylaimida is very difficult and at times causes problems for the specialist too. The large number of species on the one hand and often the meagre descriptions on the other make even well-known taxonomists to look at Dorylaimida with great hesitation and desperation. M. Shamim Jairajpuri and Wasim Ahmad have undertaken a great task in summarizing, evaluating and systematizing all the knowledge that has been published so far.

Available in PDF, EPUB and Kindle. Book excerpt: The present book is a novel attempt to make available the students an exhaustive, interesting and valuable information on the subject of Economic Zoology. All kinds of animal pathogens such as protozoans, helminths, nematodes, mites and ticks and household insects, directly or indirectly causing diseases in other animals including humans, have been described in detail covering every aspect of their life history along with the symptoms appearing on the hosts, and their prevention, control and cure. Furthermore, along with the animal pathogens mentioned above, plant pathogens, such as insects, acting as pests of a variety of crops have also been described in full detail. Apart from the harmful effects, animals are also beneficial to mankind. This seems to be justified when we go through the chapters relating to apiculture, lac culture and sericulture along with fisheries, prawn culture, pearl culture, cattle farming, pig farming and poultry farming. Key Features • Chapters enriched with photomicrographs present a realistic description. • Exclusive life cycle diagrams of pathogens are helpful in understanding important events of their life. • Exhaustive coverage of the subject matter helps students to understand the concepts with clarity and provide a wide range of information in a single volume. • Chapter-end review questions help students to prepare for the examinations and assess their subject knowledge.

Book excerpt: Pepper Virome: Molecular Biology, Diagnostics and Management presents detailed information about the plant viruses that infect pepper worldwide, providing crucial insights for both the scientific community and producers. Understanding the nature of the viruses, their transmission methods and possible sources of resistance in order to minimize the yield losses as well as to reduce the spread of these viruses to new locations or countries is of global importance.Pepper is an important commodity worldwide. It is cultivated for both fresh produce and for processing industry as a spice. However, various diseases affect pepper production and cause significant yield losses in pepper yield. The increasing outbreaks of virus species infecting Capsicum spp. have become a major problem for growers. A combination of factors, including expansion and intensification of pepper cultivation, availability of volunteer hosts, abundance of insect vectors and climate change have all contributed to the issue. Pepper Virome provides in-depth information on both the viruses infecting peppers, and eco-friendly management measures to decrease the rate of spread of viruses. Addressing the need for increased international collaboration and exchange of pepper germplasm, these insights will also facilitate the selection and breeding for improved Capsicum spp. adapted to local conditions and uses. - Focuses on symptomatology, transmission, and epidemiology of pepper viruses - Reveals the impact on host, yield, and virus-vector interactions - Evaluates management strategies against viruses and how they have evolved
