Download or read book Insect Diapause written by David L. Denlinger and published by Cambridge University Press. This book was released on 2022-02-03 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Download or read book Insect Resistance Management written by David W. Onstad and published by Academic Press. This book was released on 2013-10-08 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM. - Provides insights from the history of insect resistance management (IRM) to the latest science - Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues - Offers biochemistry and molecular genetics of insecticides presented with an emphasis on recent research - Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions

Download or read book A Handbook of Statistical Graphics Using SAS ODS written by Geoff Der and published by CRC Press. This book was released on 2014-08-15 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Easily Use SAS to Produce Your Graphics Diagrams, plots, and other types of graphics are indispensable components in nearly all phases of statistical analysis, from the initial assessment of the data to the selection of appropriate statistical models to the diagnosis of the chosen models once they have been fitted to the data. Harnessing the full graphics capabilities of SAS, A Handbook of Statistical Graphics Using SAS ODS covers essential graphical methods needed in every statistician’s toolkit. It explains how to implement the methods using SAS 9.4. The handbook shows how to use SAS to create many types of statistical graphics for exploring data and diagnosing fitted models. It uses SAS’s newer ODS graphics throughout as this system offers a number of advantages, including ease of use, high quality of results, consistent appearance, and convenient semiautomatic graphs from the statistical procedures. Each chapter deals graphically with several sets of example data from a wide variety of areas, such as epidemiology, medicine, and psychology. These examples illustrate the use of graphic displays to give an overview of data, to suggest possible hypotheses for testing new data, and to interpret fitted statistical models. The SAS programs and data sets are available online.
Download or read book Toxic Substances in Crop Plants written by J. P. Felix D'Mello and published by Woodhead Publishing. This book was released on 1991 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews current knowledge of toxic substances in crop plants with particular reference to their anti-nutritional effects in animals and man and the potential for detoxification. The distribution and ecological significance of these compounds is also addressed. Continuing disquiet over the use of animal by-products in livestock nutrition has provided renewed impetus for the greater exploitation of conventional and novel crop plants both as food and as industrial raw materials. However, a major factor restricting the utilisation of such crops in animal nutrition is the presence of a diverse array of toxic substances capable of inducing effects ranging from loss of hair and wool to severe neurological disorders and even death. Significant advances have been made to establish the nature of these compounds and to assess their effects in animals and man. As in other branches of biomedical research, these developments have been achieved through the multidisciplinary efforts of chemists, biochemists, toxicologists, nutritionists and molecular geneticists. This volume reviews current knowledge of toxic substances in crop plants with particular reference to their anti-nutritional effects in animals and man and the potential for detoxification. The distribution and ecological significance of these compounds is also addressed.
Download or read book Genetically modified crops in Africa written by Falck-Zepeda, José Benjamin and published by Intl Food Policy Res Inst. This book was released on 2013-10-02 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variable climate, political instability, and other constraints have limited agricultural development in African countries south of the Sahara. Genetically modified (GM) crops are one tool for enhancing agricultural productivity and food security despite such constraints. Genetically Modified Crops in Africa: Economic and Policy Lessons from Countries South of the Sahara investigates how this tool might be effectively used by evaluating the benefits, costs, and risks for African countries of adopting GM crops. The authors gather together studies on GM crops economic effects and impact on trade, how consumers view such crops, and other issues. They find that GM crops have had, on average, a positive economic effect in the nations where they were used and identify future steps for enhancing GM crop adoptions positive effects. Promising policy initiatives include making biosafety regulations that do not make GM crop development prohibitively expensive, fostering intraregional trade in GM crops, and providing more and better information about GM crops to consumers who might currently be skeptical of them. These and other findings in Genetically Modified Crops in Africa indicate ways biotechnology can contribute to economic development in Africa south of the Sahara.

Available in PDF, EPUB and Kindle. Book excerpt: This Reference Work is devoted to plant secondary metabolites and their evolutionary adaptation to different hosts and pests. Secondary metabolites play an important biological role in plants’ defence against herbivores, abiotic stresses and pathogens, and they also attract beneficial organisms such as pollinators. In this work, readers will find a comprehensive review of the phytochemical diversity, modification and adaptation of secondary metabolites, and the consequences of their co-evolution with plant parasites, pollinators, and herbivores. Chapters from expert contributors are organised into twelve sections that collate the current knowledge in intra-/inter-specific diversity in plant secondary metabolites, changes in secondary metabolites during plants’ adaptation to different environmental conditions, and co-evolution of host-parasite metabolites. Among the twelve themed parts, readers will also discover expert analysis on the genetics and chemical ecology evolution of secondary metabolites, and particular attention is also given to allelochemicals, bioactive molecules in plant defence and the evolution of sensory perception in vertebrates. This reference work will appeal to students, researchers and professionals interested in the field of plant pathology, plant breeding, biotechnology, agriculture and phytochemistry.

Download or read book Field Crop Arthropod Pests of Economic Importance written by Peter A. Edde and published by Academic Press. This book was released on 2021-08-21 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. - Includes insect synonyms, common names, and geographic distribution - Provides information on natural enemies - Is thoroughly referenced for future research

Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
