Systematics of the Sheath Nematodes of the Superfamily Hemicycliophoroidea


Book Description

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.

Techniques for Work with Plant and Soil Nematodes


Book Description

Plant-parasitic and free-living nematodes are increasingly important in relation to food security, quarantine measures, ecology (including pollution studies), and research on host-parasite interactions. Being mostly microscopic, nematodes are challenging organisms for research. Techniques for Work with Plant and Soil Nematodes introduces the basic techniques for laboratory and field work with plant-parasitic and free-living soil-dwelling nematodes. Written by an international team of experts, this book is extensively illustrated, and addresses both fundamental traditional techniques and new methodologies. The book covers areas that have become more widespread over recent years, such as techniques used in diagnostic laboratories, including computerized methods to count and identify nematodes. Information on physiological assays, electron microscopy techniques and basic information on current molecular methodologies and their various applications is also included.




Plant Parasitic Nematodes in Sustainable Agriculture of North America


Book Description

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.




Handbook of Invasive Plant-Parasitic Nematodes


Book Description

Plant parasitic nematodes are major pests of agricultural crops and cause huge monetary losses. There is a very high risk of spread of plant-parasitic nematodes from one country to another, with the movement of plants and planting materials such as seeds, bulbs, corms, suckers, tubers, rhizomes, rooted plants, nursery stock and cut flowers. In view of the large quantities and the wide variety of materials being imported and exported, it is important to assess the status of invasive nematodes and their quarantine importance in relation to agricultural trade. This book contains information on around 100 invasive nematodes and their potential threat in different countries. Each nematode entry includes information on authentic identification, geographical distribution, risk of introduction, host ranges, symptoms, biology, ecology, planting material liable to carry the nematode(s), nematode vectors, chance of establishment, likely impact, and phytosanitary measures. There are detailed accounts of diagnosis procedures including sampling, isolation, detection and identification of nematodes based on morphological and molecular characters. The book offers a global perspective on invasive plant-parasitic nematodes and useful for practitioners, professionals, scientists, researchers, students, and government officials working in plant quarantine and biosecurity.




Plant Nematology, 3rd Edition


Book Description

Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.

Systematics of Cyst Nematodes (Nematoda: Heteroderinae), Part A


Book Description

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.
