Download or read book Plant Pest Interactions From Molecular Mechanisms to Chemical Ecology written by Indrakant K. Singh and published by Springer Nature. This book was released on 2021-01-18 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: As food producers, plants are constantly under attack by insects. Over the course of evolution, plants have not only developed a sophisticated defense apparatus but have also refined biochemical defense mechanisms to protect themselves, thereby maintaining the ecological balance. Plant-pest interactions induce an elaborate array of reactions involving the release of volatile compounds, effector and signaling molecules, trans-membrane proteins, and a variety of enzymes and hormones. This book offers a comprehensive guide to the strategies that plants employ against insects and other pests to ensure their continued survival. Addressing an important gap in the literature, it shares the latest findings in the field of plant–pest interactions for a broad audience. Providing an overview of the current state of knowledge on plant-pest interactions and their role in the genetic improvement of crops, it offers an essential guide for researchers and professionals in the fields of agriculture, plant pathology, entomology, cell biology, molecular biology and genetics.
Download or read book Thrips Biology and Management written by Bruce L. Parker and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this book are organized as follows: insect-plant communities, host-plant selection, genetics and evolution, host-plant resistance and application of transgenic plants, and multitrophic interactions. Besides seven invited papers and a paper with concluding remarks, this volume also contains the short communications of all 115 oral presentations and posters. Included too, are the summaries of four European Science Foundation workshops held over the past two years, where European scientists discussed the state-of-the-art and the future of major topics in insect-plant interactions in order to develop better integrated research programs. The field of insect-plant interactions nowadays includes almost all of biology, as well as parts of chemistry and physics. It takes a central position in biology because insects are the most abundant animal group, half of them are herbivores and they dominate all terrestrial ecosystems. Knowledge of insect-plant interactions is thus fundamental to an understanding of the evolution of life on Earth. Two major topics of worldwide concern give this field an extra dimension. First, large amounts of food crops are still lost due to insect pests. With the increasing concern for environmental pollution and the subsequent plans to drastically reduce pesticides, integrated pest management and development of resistant crops become a major focus in agriculture. The importance of the study of insect-plant relationships is thus continuously augmented. Clearly, successful pest control demands sufficient fundamental knowledge of pest-host interactions. Second, such work can contribute towards stopping or even counterbalancing the threatening biodiversity crisis thanks to an understanding of how the interaction of insects and plants has influenced and still influences the diversification and speciation (evolution) of both groups. These problems should, of course, be approached at a multitrophic level.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims at an understanding of diverse mutualistic interactions, with all individuals tending to display their own adaptational ranges. In view of different species using different kinds of microhabitats, the diversity of assemblages goes a long way towards a better appreciation of the adaptive trends of the species involved therein. Insect assemblages and communities are shaped by the compositional, structural and trophic interactions which hold together ecological communities.

Download or read book Comparative Social Evolution written by Dustin R. Rubenstein and published by Cambridge University Press. This book was released on 2017-03-24 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin famously described special difficulties in explaining social evolution in insects. More than a century later, the evolution of sociality - defined broadly as cooperative group living - remains one of the most intriguing problems in biology. Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species, from ants to primates, highlighting key natural and life history data and providing a comparative view across animal societies. In establishing a single framework for a common, trait-based approach towards social synthesis, this volume will enable graduate students and investigators new to the field to systematically compare taxonomic groups and reinvigorate comparative approaches to studying animal social evolution.

This book was released on 2017-03-01 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid depletion and degradation of species in diverse ecosystems and the implications of this for human welfare have the cause for increasing concern. Biodiversity or variability among living organisms and the ecological complexes of which they are a part, is essential for ensuring the basic ecological services and resources necessary for sustaining human welfare. The loss of biodiversity is therefore, considered one of the most serious problem threatening the world today. An understanding of the ecological implications of the increasing loss of bodiversity, not to mention of the economic implications, has therefore, became vital. A biodiversity loss is irreversible. A calls for increased caution in our efforts to convert and exploit natural resources. Some minimal level of biodiversity is necessary to main ecological functioning, which in turn is necessary for generating the biological resources on which human welfare depends. Needless to emphasive that substantial biodiversity loss occurs due to forest clearing and degradation, leading to the need for assessing biodiversity in different ecosystems. Keeping these aspects in mind, the present volume highlights biodiversity in different cropping systems besides that the impact of cold and hot deserts. Selection of the topics in the various chapters is essentially because of the experience of the authors in the field of biodiversity.
Download or read book Insect Plant Biology written by Louis M. Schoonhoven and published by Oxford University Press. This book was released on 2005-12 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Vertical Food Web Interactions written by Konrad Dettner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past years, much work has been carried out on either life-history evolu tion or structure and function of food webs. However, most studies dealt with only one of these areas and often touched upon the other only marginally. In this volume, we try to synthesize aspects of both disciplines and will concen trate on how the interactions between organisms depend on their life-history strategies. Since this is a very comprehensive topic, this volume will focus on vertical interactions to remain within a clearly arranged field. We present some scenaria based on life-history variation of resource and consumer, and show how particular patterns of life-history combinations will lead to particular patterns in trophic relationships. We want to deal with the selective forces underlying these patterns: the degree of specificity of the consumers deter mines the dependence on its resource, and its adaptation to the spatial and temporal availability of the resource. In this respect, the spatial structure of the resource and its "quality" may play an important role. The impact of natural enemies is another important selective force which may influence the evolu tion of interactions between species and the structure of communities. Here, the acquirement of an enemy-free space may provide selective adavantages. The importance of the impact of enemies is also expressed by the development of numerous and sometimes very subtle defense strategies. This will be dem onstrated especially for various aspects of chemical ecology.

Download or read book Chemical Ecology of Insect Parasitoids written by Eric Wajnberg and published by John Wiley & Sons. This book was released on 2013-03-15 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect parasitoids are a fascinating group of animals in many respects. Perhaps the most fascinating point is that these insects, in the course of the evolutionary time, have developed an impressive way to use chemical compounds to dialogue with the different protagonists of their environment (i.e., conspecifics, their hosts and the plants on which their hosts are living). Unravelling the evolutionary meaning of such chemical communication networks can give new insights into the ecology of these insects and especially on how to improve their use for the control of noxious pests in biological control programmes. Chemical Ecology of Insect Parasitoids is a timely publication, with organised chapters to present the most important knowledge and discoveries that have taken place over the last decade, and their potential use in pest control strategy. Specific relevant case studies are presented to enhance the reader's experience. Suited to graduate students and professional researchers and practitioners in pest management, entomology, evolutionary biology, behavioural ecology, and chemical ecology, this book is essential for anyone needing information on this important group of insects.
