DOWNLOAD EBOOKSucking pests are most notorious group of pests for agricultural crops. Unlike most pests with chewing mouth parts, sucking pests cause more severe damage to the crops and are complex to get identified until advanced stages of infection. Not only is this late detection detrimental to their effective control, sucking pests also often cause fungal growth and virus transmission. The book emphasizes on sucking pests of most major crops of India. It aims to reflect Indian scenario before the international readership. This book complies comprehensive information on sucking pests of crops and brings the attention of the readers to this multiple damage causing insect complex. The chapters are contributed by highly experienced Indigenous experts from Universities & ICAR institutes, and book collates useful content for students and young researchers in plant pathology, entomology and agriculture.

DOWNLOAD EBOOK"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 EBOOKThe major temperate forage legumes are of global importance in the sustainable productivity of ruminant feed in the developed world. This book brings together in one volume all aspects of their basic biology and associated production practices. Emphasis is placed on the importance of understanding plant characteristics and their consequences in terms of forage output, quality and utilization by livestock. Recent research advances are reviewed and put into context and several recently commercialised species are also covered. The introduction considers the history, current extent, benefits and limits of temperate forage legume usage. Subsequent chapters are dedicated to a comprehensive examination of each forage species in turn, dealing with their origin, morphology, physiology, ecology, nitrogen-fixing capability, cultivars, seed production, nutritive value and productivity. The key factors for optimal management are identified and the prospects for the future outlined, including the potential arising from the use of biotechnology. This book is essential reading for degree and postgraduate students of plant science, agronomy and animal production. Additionally, students and researchers in ecology and environmental science will also find it a valuable resource. The management sections will be of particular value to grassland advisers, consultants and progressive land users.

DOWNLOAD EBOOKThis timely book provides an overview of the anatomical, chemical, and developmental features contributing to plant defense, with an emphasis on plant responses that are induced by wounding or herbivore attack. The book first introduces general concepts of direct and indirect defenses, followed by a focused review of the different resistance traits. Finally, signal perception and transduction mechanism for the activation of plant defense responses are discussed.
