Download or read book Aphid Biodiversity under Environmental Change written by Pavel Kindlmann and published by Springer Science & Business Media. This book was released on 2010-07-01 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings out the world record of various predatory insects and their role in pestiferous insect management in a safer manner. The main focus of the book is to address the ecological and environmentally safe methods of managing pests of various crops. The utilization of various types of chemical pesticides for our crop protection and food production leads to environmental concerns and health hazards to plants and animals. This book mainly focuses on the distribution and diversity of various predatory insects in different crops. It also sellout the bionomics, biological control potential at a laboratory, controlled fields and natural conditions. Moreover, mass production technology and environmental safety aspects are also highlighted in various chapters. This book is of interest and useful to undergraduates, post-graduates, research scholars and doctoral candidates, extension workers, and agricultural professionals, and also a valuable source of reference to the relevant researchers and students in the region.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i
