Book Description
Our objective in compiling a series of chapters on the chemical ecology of insects has been to delineate the major concepts of this discipline. The fine line between presenting a few topics in great detail or many topics in veneer has been carefully drawn, such that the book contains sufficient diversity to cover the field and a few topics in some depth. After the reader has penetrated the crust of what has been learned about chemical ecology of insects, the deficiencies in our understanding of this field should become evident. These deficiencies, to which no chapter topic is immune, indicate the youthful state of chemical ecology and the need for further investigations, especially those with potential for integrating elements that are presently isolated from each other. At the outset of this volume it becomes evident that, although we are beginning to decipher how receptor cells work, virtually nothing is known of how sensory information is coded to become relevant to the insect and to control the behavior of the insect. This problem is exacerbated by the state of our knowledge of how chemicals are distributed in nature, especially in complex habitats. And finally, we have been unable to understand the significance of orientation pathways of insects, in part because of the two previous problems: orientation seems to depend on patterns of distri bution of chemicals, the coding of these patterns by the central nervous system, and the generation of motor output based on the resulting motor commands.

Book Description
This fully revised and updated second edition of Insect Pests of Potato now includes an opening section with a basic overview of agronomic and economic issues as they relate to potato production. It also features a new section that reviews potato production, as well as problems caused by insect pests and solutions to these problems, in all major potato-growing regions of the world. Further, a new section discusses theoretical foundations of potato pest management and includes chapters on ecological theory, evolutionary theory, and a case study on their applications to elucidate differences between Eastern and Western populations of Colorado potato beetle in North America. There is also a new chapter on the foundations of integrated pest management and their applications in controlling insect pests. The sections on the biology of main pests and on control methods now feature the latest information, including emphasis on recent advances in molecular biology and genomics. Information on the use of dsRNA technology for pest control is also included, as are new chapters on potato ladybirds and on hemipterous pests other than aphids and psyllids. This second edition provides improved integration and logical connections among chapters and expanded geographic scope of coverage making it the ideal reference on the topic. - Fully revised and updated with new sections on potato-growing regions and theoretical foundations of potato pest management using ecological theory, evolutionary theory and relevant case study insights - Contains improved integration and logical connections among chapters, expanded geographic scope of coverage, and scientific advances - Emphasizes recent advances in molecular biology and genomics, including the use of dsRNA technology for pest control

Book Description
"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.

Book Description
Potato (Solanum tuberosum L.) is the fourth-largest food crop produced in the world with approximately 370 million tonnes. This product is a staple in many diets throughout the world and the underground swollen tubers of the plant are rich sources of proteins, carbohydrates, minerals (K, Mn, Mg, Fe, Cu and P), and vitamins (C, B1, B3, B6, K, folate, pantothenic acid). Improvement of new potato cultivars resistant to biotic and abiotic factors is extremely important, as these are the main reasons for decreased potato production. Seed tuber production and tuber storage under healthy conditions after harvest are two important issues in potato cultivation. As such, this book discusses the importance of the potato plant and examines ways to increase its production and develop new cultivars resistant to stress factors via conventional and biotechnological methods.

Book Description
Sustainable Management of Arthropod Pests of Tomato provides insight into the proper and appropriate application of pesticides and the integration of alternative pest management methods. The basis of good crop management decisions is a better understanding of the crop ecosystem, including the pests, their natural enemies, and the crop itself. This book provides a global overview of the biology and management of key arthropod pests of tomatoes, including arthropod-vectored diseases. It includes information that places tomatoes in terms of global food production and food security, with each pest chapter including the predators and parasitoids that have specifically been found to have the greatest impact on reducing that particular pest. In-depth coverage of the development of resistance in tomato plants and the biotic and abiotic elicitors of resistance and detailed information about the sustainable management of tomato pests is also presented. - Provides basic biological and management information for arthropod pests of tomato from a global perspective, encompassing all production types (field, protected, organic) - Includes chapters on integrated management of tomato pests and specific aspects of tomato pest management, including within protected structures and in organic production - Presents management systems that have been tested in the real-world by the authors of each chapter - Fully illustrated throughout with line drawings and color plates that illustrate key pest and beneficial arthropods associated with tomato production around the world
