Available in PDF, EPUB and Kindle. Book excerpt: Most people know of aphids as garden pests, infesting the soft green tissues of plants in vast numbers and killing them by sucking out the sap. Indeed, among the 4000 or so known species of aphids about 250 are pests, and in temperate regions several are economically important agricultural pests that damage crops directly during feeding or act as vectors for plant pathogens. But aphids are also important model organisms in evolutionary biology and ecology because they combine a number of unique features such as complex life cycles involving the development of morphological distinct phenotypes (polyphenism), sexual and asexual reproduction strategies and changes of host plants. Aphids can also be regarded as holobionts because they are colonized by obligate and facultative microbes which enable them to feed exclusively on phloem sap and influence their resistance against pathogens, parasitoids or environmental stress. This book combines fundamental information about aphids with chapters addressing state-of-the-art research in topics such as aphid-related phylogeny, genome biology, epigenetics and chemical ecology.

Download or read book Aphid Biodiversity under Environmental Change written by Pavel Kindlmann and published by Springer. This book was released on 2014-11-07 with total page 0 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: Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.

Download or read book Comparative Social Evolution written by Dustin R. Rubenstein and published by Cambridge University Press. This book was released on 2017-03-24 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin famously described special difficulties in explaining social evolution in insects. More than a century later, the evolution of sociality - defined broadly as cooperative group living - remains one of the most intriguing problems in biology. Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species, from ants to primates, highlighting key natural and life history data and providing a comparative view across animal societies. In establishing a single framework for a common, trait-based approach towards social synthesis, this volume will enable graduate students and investigators new to the field to systematically compare taxonomic groups and reinvigorate comparative approaches to studying animal social evolution.

Download or read book Chemical Ecology of Insects written by William J. Bell and published by Springer. This book was released on 2013-11-27 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective in compiling a series of chapters on the chemical ecology of insects has been to delineate the major concepts of this discipline. The fine line between presenting a few topics in great detail or many topics in veneer has been carefully drawn, such that the book contains sufficient diversity to cover the field and a few topics in some depth. After the reader has penetrated the crust of what has been learned about chemical ecology of insects, the deficiencies in our understanding of this field should become evident. These deficiencies, to which no chapter topic is immune, indicate the youthful state of chemical ecology and the need for further investigations, especially those with potential for integrating elements that are presently isolated from each other. At the outset of this volume it becomes evident that, although we are beginning to decipher how receptor cells work, virtually nothing is known of how sensory information is coded to become relevant to the insect and to control the behavior of the insect. This problem is exacerbated by the state of our knowledge of how chemicals are distributed in nature, especially in complex habitats. And finally, we have been unable to understand the significance of orientation pathways of insects, in part because of the two previous problems: orientation seems to depend on patterns of distri bution of chemicals, the coding of these patterns by the central nervous system, and the generation of motor output based on the resulting motor commands.
Download or read book Ecology and Behaviour of the Ladybird Beetles Coccinellidae written by Ivo Hodek and published by John Wiley & Sons. This book was released on 2012-04-19 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ladybirds are probably the best known predators of aphids and coccids in the world, though this greatly underestimates the diversity of their biology. Maximising their impact on their prey is an important element in modern conservation biological control of indigenous natural enemies in contrast to the classical approach of releasing alien species. Ivo Hodek is one of the most internationally respected experts on coccinellids who has researched these insects for his entire career. He has now brought together 14 scientists of international standing to author 12 chapters, making this book the definitive treatment of coccinellid biology and ecology. This volume covers the rapid scientific developments of recent years in the understanding of coccinellid phylogeny, the semiochemicals influencing their behaviour and of molecular genetics. Recent insights in relation to intraguild predation and the assessment of the predatory impact of coccinellids are also covered. Other special features of the volume are the extensive references covering the literature from both East and West and a taxonomic glossary of the up-to-date nomenclature for species of coccinellids as well as of other organisms mentioned in the text. While aimed at researchers, university teachers and agricultural entomologists, the book is readable and appropriate for others who just have a liking for these interesting and attractive insects.
