Book Description
Poisoning due to Cucurbitaceous vegetables seems to be linked to intake of immensely bitter vegetables. The bitter and toxic compounds in these vegetables are cucurbitacins, which are well known in wild varieties of these food plants and their related species. The cultivated forms, on the other hand, have during cultivation been selected for being free of the bitter and toxic compounds. Occasionally, cultivars of cucurbitaceous food plants (e.g. squash) back-mutate and regain the ability to produce toxic amounts of cucurbitacins. This review summarises the information available on cucurbitacins in food plants of the family Cucurbitaceae, with the aim to lay down background information required to evaluate the potential risk of being intoxicated by cucurbitacins as a part of the safety assessment of cucurbitaceous food plants, and especially in relation to genetically modified Cucurbitaceous plants.

Book Description
Food safety is important and consumers have a right to expect that those who supply the food that they buy have taken every care to manufacture products that will do them no harm. Those with a responsibility for the regulation of the global food industry recognise this principle and legislate accordingly and the business of managing and regulating the safety of the food supply chain has come a long way in the last 25 years or so. Prompted by the emergence of new food safety hazards, such as the bacterial pathogens Listeria monocytogenes and E. coli O157, powerful new techniques for evaluating and managing the risks presented by these threats have been developed. For example, hazard analysis critical control point, or HACCP, has now become the food safety management system of choice worldwide. Although the food safety management tools are now widely available, they are still virtually useless unless they are supported by adequate and accurate information. HACCP does not work unless its practitioners have access to enough data and scientific knowledge to enable them to understand hazards and how to control them effectively. The Food Safety Hazard Guidebook is an attempt to address the problem of accessing the available information by distilling the key facts about a wide range of individual food safety hazards into a single text. The result is a guidebook, rather than an encyclopaedia, which acts as a portal for the immense and ever expanding body of scientific knowledge that exists for food safety. It is an easy-to-use information resource for anyone with a professional interest in the safety of the food supply. The book is easy to navigate and presents concise and carefully researched factual information on a wide range of biological and chemical hazards in a clear format that is designed to support risk analysis exercises and HACCP studies. It covers a broad range of established and emerging food safety hazards and includes details of authoritative sources of further information (many web-based) for those seeking to examine a topic in greater depth. The section on food allergens is a particularly valuable component of the book, the chapters on fish toxins are also useful and unusual in a book of this kind and bacterial pathogens are comprehensively covered. One of the most important features of the book is the wide scope of the content and the highly structured format designed to help the reader find information quickly. Other key benefits to the reader are: -The wide range of biological and chemical hazards covered in a single book -Written specifically with food industry professionals in mind -Easy to navigate and accessible for the non-expert -Clear and concise presentation of factual information presented in a format that lends itself to use in risk assessment exercises -Inclusion of references and web links to reliable sources of further information on each chapter -specifically designed for practical use by a professional readership.

Book Description
This volume presents the latest research on herbivores, aquatic and terrestrial mammals and insects. The Second Edition, written almost entirely by new authors, effectively complements the initial work. It includes advances in molecular biology and microbiology, ecology, and evolutionary theory that have been achieved since the first edition was published in 1979. The book also incorporates relatively new methodologies in the area of molecular biology, like protein purification and gene cloning. Volume II, Ecological and Evolutionary Processes, also opens up entirely new subjects: The discussions of interactions have expanded to include phenomena at higher trophic levels, such as predation and microbial processing and other environmental influences. Both this and Volume I, The Chemical Participants, will be of interest to chemists, biochemists, plant and insect ecologists, evolutionary biologists, physiologists, entomologists, and agroecologists interested in both crop and animal science. - Presents coevolution of herbivores and host plants - Examines resource availability and its effects on secondary metabolism and herbivores - Studies physiology and biochemistry of adaptation to hosts - Includes tri-trophic interactions involving predators and microbes

Book Description
Plant-parasitic nematodes (PPNs) devastate many crop plants, causing billions of dollars in agricultural losses each year. Effective management methods to combat PPNs are synthetic nematicides, but most are non-specific and notoriously toxic and threaten the soil ecosystem, groundwater and human health. The plant by-products, such as oilseed cakes, are sources of bioactive compounds with nematicidal potential. Oilseed cakes are an excellent organic fertilizer, and their bioactive compounds are now gaining importance as they are safe for the environment. This book provides the most comprehensive and up-to-date review of research on the use of oilseed cakes against PPNs. The complete knowledge of better uses of oilseed cakes for nematode management is necessary for developing effective nematode control options to reduce yield loss. Key features: • Describes plant by-products such as oilseed cakes and their potential applications • Explores bioactive compounds from oilseed cakes for agricultural biofertilization and nematicidal activity • Discusses nematode management in vegetable, fruit and legume crops • Covers the use of oilseed cakes and management of the associated challenges This volume is designed and edited to serve as an invaluable resource text for readers associated with plant nematology, plant pathology, plant protection and agricultural science, including researchers, teachers, advanced undergraduates and graduate students and even agricultural extension agents and farmers.

Book Description
For more than 20 years insect/plant relations have been a focus for studies in ecology and evolution. The importance of insects as crop pests, and the great potential of insects for the biological control of weeds, have provided further impetus for work in this area. All this attention has resulted in books on various aspects of the topic, and reviews and research papers are abundant. So why write another book? It seems to us that, in the midst of all this activity, behavior has been neglected. We do not mean to suggest that there have not been admirable papers on behavior. The fact that we can write this book attests to that. But we feel that, too often, behavior is relegated to a back seat. In comparison to the major ecological and evolutionary questions, it may seem trivial. Yet the whole process of host-plant selection and host-plant specificity amongst insects depends on behavior, and selection for behavioral differences must be a prime factor in the evolution of host-plant specificity. In writing this book, we hope to draw attention to this central role of behavior and, hopefully, encourage a few students to attack some of the very difficult questions that remain unanswered.
