Book Synopsis Insect-Plant Biology by : Louis M. Schoonhoven
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.

Available in PDF, EPUB and Kindle. Book excerpt: Harvested Forages deals with the subject of food for domestic animal feeding. Such food is called "forage" and includes things like alfalfa and other plants usually referred to as "hay." Topics include the ways that this forage is produced, how it is harvested, and ways that it should be stored. Other issues that are dealt with include various criteria and measurement procedures for assessing forage nutritive quality, potential health hazards associated with particular plants and plant toxins, and various issues of plant growth, pest control, and soil fertility--among other topics. This book is essential for any institution with a strong program in range sciences, animal sciences, animal feeding and nutrition, and related programs. - Synthesizes and summarizes a vast and widely dispersed literature in animal science - Serves as a reference for managers of harvested forages as well as all those involved with the forage production industry

Book Synopsis Biodiversity and Chemotaxonomy by : Kishan Gopal Ramawat
Download or read book Biodiversity and Chemotaxonomy written by Kishan Gopal Ramawat and published by Springer Nature. This book was released on 2019-11-10 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant classifications are based on morphological characters and it is difficult, particularly in small plants and grasses, to identify these below generic level on the basis of these characters using a dissecting microscope. Plant species have intra- and inter-specific variation in secondary metabolites which can be utilized as marker compounds for identification and classification of plants. Secondary metabolites are produced as a result of primary metabolism and the production of these compounds not only involves several genes but also it is an energy dependent process. Hence these products cannot be considered as insignificant for the plant and the environment. Modern tools of molecular biology and secondary metabolites present in them can definitively decide about classification of plants. Absence of correct identification of plant is associated to many problems of resource utilization. Due to wide availability of these tools, interest has revived in systematics and correct classification of plants based on these parameters for their sustainable utilization and resource management. The purpose of this book is to assess the potential of phytochemical and molecular tools in the systematic and classification of plants. The topics covered include species concept, barcoding and phylogenetic analysis, chemotaxonomy use of polyketides, carotenes, cuticular wax, volatile oils, biodiversity of corals, metazoans, Ruta and Echinocereus. It provides comprehensive and broad subject-based reviews, useful for students, teachers, researchers, and all others interested in the field. The field has been kept wide and general to accommodate the wide-ranging topics. This book will be useful to agriculturists, chemists, botanists, industrialists, and those involved in planning of crop plants.
Book Synopsis Handbook of Biological Control by : T. W. Fisher
Download or read book Handbook of Biological Control written by T. W. Fisher and published by Elsevier. This book was released on 1999-09-20 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years the use of chemical agents such as pesticides and herbicides has been effective in controlling the many varieties of pests that infest both agricultural crops and backyard gardens. However, these pests are gradually becoming resistant to these agents, because the agents themselves are acting as selective factors making the pests better and better able to resist and persist. As a result, the use of biological controlling agents is increasing. This book is a comprehensive and authoritative handbook of biological control.

Book Synopsis Pests and Pathogens by : Peter G. Ayres
Download or read book Pests and Pathogens written by Peter G. Ayres and published by Garland Science. This book was released on 1992 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pests and pathogens cause enormous damage to crops and natural vegetation but their effects are usually studied separately. This new review volume covers both subjects with the aim of establishing where their effects overlap or where there are essential differences. Plant responses to pests are triggered by injury to photosynthetic tissue. The usual physiological response is a modification of growth to minimize damage. In populations of wild plants, a loss of competitive and reproductive fitness normally occurs, whereas crops suffer from a lower harvestably yield. By reviewing areas of commonality it is intended that crop loss assessment models can be refined and improved, particularly since pests and pathogens often affect crops simultaneously. Recent advances in the understanding of basic wound responses, and both intra- and inter-plant signalling, reveal the extent to which the biochemistry of different defence mechanisms may have diverged from common origins in the course of evolution. Understanding the reasons for this divergence will, in the long term, greatly benefit efforts in plant breeding. It is intended for plant researchers; postgraduates and final year undergraduate students in plant biology (particularly plant pathology), agricultural botany and entomology.
