Available in PDF, EPUB and Kindle. Book excerpt: Designed to introduce students and research workers to insect herbivore-host dynamics, this book uses the interaction between aphids and trees as a model. Challenging the belief that population dynamics of insect herbivores are heavily influenced by the action of their natural enemies, it demonstrates that tree dwelling species of aphids actually regulate their own population through competition for resources.

Available in PDF, EPUB and Kindle. Book excerpt: Literature on the population dynamics of insect herbivores tends to favour a top-down regulation of abundance, owing much to the action of natural enemies. Originally published in 2005, this volume challenges this paradigm and argues that tree-dwelling species of aphids, through competition for resources, regulate their own abundance. The biology of tree-dwelling aphids is examined, particularly their adaptation to the seasonal development of their host plants. When host-plant quality is favourable, aphids, by telescoping generations, can achieve prodigious rates of increase which their natural enemies are unable to match. Using analyses of long-term population censuses and results of experiments, this book introduces students and research workers to insect herbivore-host dynamics using the interaction between aphids and trees as a model.

Download or read book Specialization Speciation and Radiation written by Kelley Tilmon and published by Univ of California Press. This book was released on 2008-01-03 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intimate associations between plants and the insects that eat them have helped define and shape both groups for millions of years. This pioneering volume is a comprehensive, up-to-date treatment of the evolutionary biology of herbivorous insects, including their relationships with host plants and natural enemies. Chapters focus on the dynamic relationships between insects and plants from the standpoint of evolutionary change at different levels of biological organization—individuals, populations, species, and clades. Written by prominent evolutionary biologists, entomologists, and ecologists, the chapters are organized into three sections: Evolution of Populations and Species; Co- and Macroevolutionary Radiation; and Evolutionary Aspects of Pests, Invasive Species, and the Environment. The volume is unified by the idea that understanding the ecological framework of the interactions between herbivorous insects and their host plants is fundamental to understanding their evolution.

The topics comprise a fascinating and deep coverage of what has been discovered in the prolific recent decades of research with insects on plants. Fascinating chapters provide deep analyses of some of the most interesting research on these interactions. From insect plant chemistry, behavior, and host shifting to phylogenetics, co-evolution, life-history evolution, and invasive plant-insect interaction, one is hard pressed to name a substantial topic not included. This volume will launch a hundred graduate seminars and find itself on the shelf of everyone who is anyone working in this rich landscape of disciplines."--Donald R. Strong, Professor of Evolution and Ecology, University of California, Davis "Seldom have so many excellent authors been brought together to write so many good chapters on so many important topics in organismic evolutionary biology. Tom Wood, always unassuming and inspired by living nature, would have been amazed and pleased by this tribute."--Mary Jane West-Eberhard, Smithsonian Tropical Research Institute
Download or read book Variable plants and herbivores in natural and managed systems written by Robert Denno and published by Elsevier. This book was released on 2012-12-02 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variable Plants and Herbivores in Natural and Managed Systems examines individual, population, species, and community responses of herbivores to plant variation, with emphasis on insects, fungi, bacteria, and viruses. It is divided into five parts encompassing 18 chapters that discuss variability as a mechanism of defense used by plants against their parasites and the effects of variability on herbivores at several different levels of complexity. After a brief discussion on plant-herbivore interactions, the first part of this book considers sources of within-plant variation and effects on the distribution and abundance of herbivores. Part II examines interplant variation, the co-evolutionary problems it poses for herbivores, and the ecological and evolutionary responses of these animals. It discusses the effects of host-plant variability on the fitness of sedentary herbivorous insects. Part III discusses the role of host variability in the evolution of feeding specialization, genetic differentiation, and race formation. The importance of host variation to the organization of herbivore communities and the manipulation of host-plant variability for the management of herbivore pest populations are presented in the remaining parts. This book will be helpful to agriculturists, silviculturists, biologists, and researchers who wish to expand their knowledge in dynamics of plant-herbivore relationships.

The book also presents the first available review on physicochemical conditions of the gut lumen from an ecological perspective.
Download or read book Insect Outbreaks Revisited written by Pedro Barbosa and published by John Wiley & Sons. This book was released on 2012-06-29 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important. This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks. Insect Outbreaks Revisited is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.

This book was released on 2012-12-02 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aimed primarily at advanced graduate students and professional biologists, this book explores the degree to which animal*b1plant interactions are determined by plant and animal variability. Many of the patterns seen in natural communities appear to result from cascading effects up as well as down the trophic system. Variability among primary producers can influence animal and plant population quality and dynamics, community structure, and the evolution of animal*b1plant interations.
Download or read book Herbivorous Insects written by Sami Ahmad and published by Elsevier. This book was released on 2012-12-02 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbivorous Insects: Host-Seeking Behavior and Mechanisms addresses mechanisms of searching behavior leading ultimately to host location of herbivorous insects. It is divided into four sections, wherein the first two sections deal with neurophysiology and the diversity of behavioral induction cues. The third section covers the searching mechanisms as affected by insects' breadth of diet. The last part examines the evolutionary analysis of the behavioral and physiological adaptations in insect/host plant relations. This book starts with an introduction to the chemical sensory system as it relates to host selection in general. This is followed by considerable discussions on host-seeking behavior and allied patterns in behavior. This text also includes the study of oviposition behavior in butterflies belonging to Papilionidae. The third section presents host selection and colonization by three insects within the saprophage-predator continuum, namely, Hylurgopinus rufipes, Scolytus multistriatus, and Pissodes strobi. The behaviors by which certain oligophagous insects locate and select food plants are also considered. The concluding part addresses the unifying theme and the diversity of responses of phytophagous insects to plants. The book provides direction toward developing a unifying theme and improving the ability to unravel the complexities of insect/plant interactions. Behaviorists, ecologists, entomologists, evolutionary biologists, and physiologists will find this book invaluable.
