Aphid Biodiversity under Environmental Change
Author: Pavel KindlmannPublisher: Springer Science & Business Media
ISBN: 9048186013
Category : Science
Languages : en
Pages : 197
Book Description
This book presents the results of recent research on aphid population dynamics and ecology relevant to current environmental changes resulting from global wa- ing. It incorporates a selection of the contributions presented at the International Symposium on Aphids in Fremantle, Australia, in October 2005, plus some ad- tional invited chapters. The objective was to incorporate the major issues in the ?eld and simultaneously create a closely interrelated and integrated volume. The ?rst chapter sets the scene. Kindlmann and Dixon present a critical review of existing models of aphid population dynamics, examine the biological assumptions that are incorporated in the models and present one of the latest models of aphid metapopulation dynamics. They conclude that natural enemies are unlikely to affect aphid population dynamics late in a season, but in some years may have an effect very early in the season, when aphid colonies are still small and predators might be able to reduce the numbers of colonies. The question, whether aphids will move to different locations, adapt to the change in conditions in their current habitat or go extinct is discussed by Ameixa. She concludes that the distributions of aphids are most likely to change, with the distribution of each species moving globally as their preferred habitat moves in response to changes in the climate, which may be more dif?cult than in the past because of habitat fragmentation and habitat loss.

Theory and Practice of Biological Control
Author: C.B. HuffakerPublisher: Elsevier
ISBN: 0323142443
Category : Technology & Engineering
Languages : en
Pages : 811
Book Description
The Theory and Practice of Biological Control covers conventional biological control achievement in the major crop types and in public health problems. Composed of five sections encompassing 28 chapters, this book discusses the basic information concerning developments in other biologically based alternatives to chemical pesticides. The first two sections discuss the philosophy, theory, scope, history, and the biological and ecological bases of biological control. These sections also deal with the impact of predators and the host relationships of parasitoids and pathogens. The following section presents the methodological aspects of biological control. Discussions on the variability of natural enemies as encountered in biological control work; the fitness of individuals and populations; the ways fitness is being or can be influenced by importation procedures; and the ability of imported natural enemies to adapt to the new environment are included. The fourth section outlines the accomplishments of conventional biological control in various types of crops, forests, and public health areas. Lastly, the various components of integrated pest control other than conventional biological control that forms the essential ways used in the integrated control approach are covered in the last section of the book. This book is an ideal source for plant pathologists and researchers, microbiologists, parasitologists, and public health professionals.
