The Coccinellidae are a family of beetles, known variously as ladybirds or ladybugs. In Britain alone, some 46 species belong to the Coccinellidae family, although only 26 of these are recognisably ladybirds. Composed largely of Professor Michael Majerus' lifetime work, and updated by two leading experts in the field, this book reveals intriguing insights into ladybird biology from a global perspective. The popularity of this insect group has been captured through societal and cultural considerations, coupled with detailed descriptions of complex scientific processes, to provide a comprehensive and accessible overview of these charismatic insects. Bringing together many studies on ladybirds, this book has been organised into themes, ranging from anatomy and physiology to ecology and evolution. This book is suitable for interested amateur enthusiasts, and researchers involved with ladybirds, entomology and biological control.

Bogland habitat, which is often threatened by peat extraction, has enormous natural history value. As well as the better-known plants, dragonflies and birds, it supports a unique community of microscopic animals and plants inhabiting the leaves and crevices of Sphagnum, the moss that dominates bog vegetation. Under the microscope, a single drop of water squeezed from bog moss reveals a wonderful diversity of complex and distinctive organisms. The peculiar characteristics of this bog moss habitat are described, and the book introduces the natural history and ecological interrelationships of its microscopic organisms, focusing in particular on the more obvious and elegant groups: the desmids, diatoms, shelled amoebae and rotifers or wheel animalcules. Identification is assisted by numerous detailed line illustrations and by the coloured plates. User-friendly keys will help the reader to allocate specimens to a group, and to name the more conspicuous genera of flagellates, desmids, diatoms, shelled amoebae and rotifers, as well as some species of Sphagnum itself. This is digital reprint of 0855462914 (1993).

Insects display a staggering diversity of behaviors. Studying these systems provides insights into a wide range of ecological, evolutionary, and behavioral questions including the genetics of behavior, phenotypic plasticity, chemical communication, and the evolution of life-history traits. This accessible text offers a new approach that provides the reader with the necessary theoretical and conceptual foundations, at different hierarchical levels, to understand insect behavior. The book is divided into three main sections: mechanisms, ecological and evolutionary consequences, and applied issues. The final section places the preceding chapters within a framework of current threats to human survival - climate change, disease, and food security - before providing suggestions and insights as to how we can utilize an understanding of insect behavior to control and/or ameliorate them. Each chapter provides a concise, authoritative review of the conceptual, theoretical, and methodological foundations of each topic.

Comprising a substantial part of living biomass on earth, ants are integral to the functioning of terrestrial ecosystems. More than 12,500 species have been described to date, and it is estimated that perhaps as many still await classification.
Ant Ecology explores key ecological issues and new developments in myrmecology across a range of scales. The book begins with a global perspective on species diversity in time and space, and examines interactions at the community level before describing the population ecology of these social insects. The final section covers the recent ecological phenomenon of invasive ants: how they move across the globe, invade, affect ecosystems, and are managed by humans. Each chapter links ant ecology to broader ecological principles, provides a succinct summary, and discusses future research directions. Practical aspects of myrmecology, applications of ant ecology, debates, and novel discoveries are highlighted in text boxes throughout the volume. The book concludes with a synthesis of the current state of the field and a look at exciting future research directions. The extensive reference list and full glossary are invaluable for researchers, and those new to the field.

Under continual attack from both microbial pathogens and multicellular parasites, insects must cope with immune challenges every day of their lives. However, this has not prevented them from becoming the most successful group of animals on the planet. Insects possess highly-developed innate immune systems which have been fine-tuned by an arms race with pathogens spanning hundreds of millions of years of evolutionary history. Recent discoveries are revealing both an unexpected degree of specificity and an indication of immunological memory - the functional hallmark of vertebrate immunity. The study of insect immune systems has accelerated rapidly in recent years and is now becoming an important interdisciplinary field. Furthermore, insects are a phenomenally rich and diverse source of antimicrobial chemicals. Some of these are already being seriously considered as potential therapeutic agents to control microbes such as MRSA. Despite a burgeoning interest in the field, this is the first book to provide a coherent synthesis and is clearly structured around two broadly themed sections: mechanisms of immunity and evolutionary ecology. This novel text adopts an interdisciplinary and concept-driven approach, integrating insights from immunology, molecular biology, ecology, evolutionary biology, parasitology, and epidemiology. It features contributions from an international team of leading experts. Insect Infection and Immunity is suitable for both graduate students and researchers interested in insect immunity from either an evolutionary, genetical, physiological or molecular perspective. Due to its interdisciplinary and concept-driven approach, it will also appeal to a broader audience of immunologists, parasitologists and evolutionary biologists requiring a concise overview.

'Brilliant, Fantastic and Significant' - Dr George McGavin Ants are seemingly everywhere, and this familiarity has led to some contemptuous and less than helpful stereotypes. In this compelling insight into the natural and cultural history of ants, Richard Jones helps to unravel some of the myths and misunderstanding surrounding their remarkable behaviours. Ant aggregations in large (often mind-bogglingly huge) nests are a complex mix of genetics, chemistry, geography and higher social interaction. Their forage trails - usually to aphid colonies but occasionally into the larder - are maintained by a wondrous alchemy of molecular scents and markers. Their social colony structure confused natural philosophers of old and still taxes the modern biologist today. Beginning the book with a straightforward look at ant morphology, Jones then explores the ant species found in the British Isles and parts of nearby mainland Europe, their foraging, nesting, navigating and battle instincts, how ants interact with the landscape, their evolution, and their place in our understanding of how life on earth works. Alongside this, he explores the complex relationship between humans and ants, and how ants went from being the subject of fables and moral storytelling to become popular research tools. Drawing on up-to-date science and featuring striking colour photographs throughout, this book presents a convincing case for why ants are worth our greater recognition and respect.

This volume is an account of the scientific and social responses made to the discovery of an invasive forest insect - the emerald ash borer or EAB (Agrilus planipennis Fairmaire, 1888) - in North America, that was formally announced in July 2002. Since its recognition, this wood-boring beetle has become one of the most destructive and costly exotic species ever encountered. More than $300 million in federal USDA-APHIS funds (alone) have been devoted to battling this pest, which has killed some tens of millions of ash trees, chiefly within southeastern Michigan and surrounding states. EAB has now been found in 28 states and two Canadian provinces. But those numbers are almost certain to keep growing in coming years. While primarily a case study, this work nonetheless examines larger issues concerning invasive species as a whole, their inadvertent transport and worldwide spread through the rise of globalization, regulations that have been adopted to prevent their introduction, and the successes or failures of state and federal agencies to try and enforce those regulations. It offers the first general work of its kind to appear on the ash borer that is directed towards a broad audience including the public, entomologists and foresters, environmentalists and ecologists, researchers, regulators, and indeed anyone who wishes to learn more about this important and timely topic. No previous knowledge of EAB or invasion biology is assumed. This book covers all of the major aspects of scientific research and management that have occurred since EAB was recognized in 2002. It is thoroughly researched and draws from the best available data and sources, which represent (a) archival materials; (b) scholarly publications and conference proceedings; (c) interviews conducted with leading participants in the EAB program; (d) selected newspaper/magazine articles; and (e) reputable sources found on the Internet (e.g., USDA-APHIS).

"In this enormously useful book, a profound need is met by a profound contribution, the first such comprehensive work in over fifty years. While brief, "Ants of North America" is the distillation of a vast amount of study and practice. It is a joy to browse and read, and will have an important impact on the study of ants."--Edward O. Wilson, University Research Professor Emeritus, Harvard University
"Two of the most prolific ant faunists have produced a marvelous taxonomic guide to the ant genera of North America. The keys and genus descriptions are succinct and easy to read, the illustrations superb. This book is a must for entomologists, ecologists, and particularly all who study ants."--Bert Holldobler, Foundation Professor of Life Sciences, Arizona State University
"This book represents a bold advance in the study of North American ants. It provides, for the first time, an accessible and lavishly illustrated guide to all the ant genera occurring in the United States and Canada. It will greatly enhance both public interest in ants and scientific investigation of their ecology, behavior and evolution."--Philip S. Ward, Department of Entomology and Center for Population Biology, University of California at Davis

This book provides an overview of our current understanding of polyembryony in insects. The study of polyembronic insects has advanced considerably over the last several decades.The book shows the exciting potential of polyembryonic insects and their impact on life sciences. It describes the mechanisms of polyembryogenesis; tissue-compatible invasion of the host, which is the first case of compatible cellular interaction between phylogenetically distant organisms without rejection; the sex differences in defense; and the environmental regulation of caste structure. The first book devoted to polyembryony in insects, it draws on the author's research on polyembryonic wasps from 1990 to the present day, covering various topics such as polyembryogenesis in vitro, host-parasite interaction, sex differences in soldier function/humoral toxic factor, and the transcription analysis of polyembryogenesis.It is intended not only for researchers in the field of entomology, parasitology, ontogeny, reproductive biology, developmental biology, sociobiology, and evolutionary developmental biology (Evo-Devo), but also for postgraduate students in these fields.

This book provides an in-depth review and analysis of the biology of adults and larvae of the Family "Oestridae" (commonly known as botflies, or warble flies). Oestrid flies cause myiasis (invasion of living tissue by the larvae), and are a major pest of both domestic and wild animals worldwide. The book presents a comparative investigation of the life histories and adaptation to parasitism exhibited by this unique family of flies. It also gives a detailed survey of each genus and provides a synopsis of the taxonomy of the family. It contains chapters on morphology, life history, host-parasite relationships, taxonomy and behavior.

Many international forums have identified the need for comprehensive, scientific methods for the pre-release testing and post-release monitoring of transgenic plants to ensure their environmental safety and sustainable use. In response to this requirement, a GMO Guidelines Project was established under the aegis of the International Organization for Biological Control, to develop biosafety testing guidelines for transgenic plants. This second volume focuses on transgenic cotton in Brazil and addresses both environmental and agricultural impacts. It draws out some general risk assessment guidelines and demonstrates the need for case-by-case analysis.

In many ecosystems dung beetles play a crucial role--both ecologically and economically--in the decomposition of large herbivore dung. Their activities provide scientists with an excellent opportunity to explore biological community dynamics. This collection of essays offers a concise account of the population and community ecology of dung beetles worldwide, with an emphasis on comparisons between arctic, temperate, and tropical species assemblages. Useful insights arise from relating the vast differences in species' life histories to their population and community-level consequences. The authors also discuss changes in dung beetle faunas due to human-caused habitat alteration and examine the possible effects of introducing dung beetles to cattle-breeding areas that lack efficient native species. "With the expansion of cattle breeding areas, the ecology of dung beetles is a subject of great economic concern as well as one of intense theoretical interest. This excellent book represents an up-to-date ecological study covering important aspects of the dung beetle never before presented."--Gonzalo Halffter, Instituto de Ecologia, Mexico City Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Charles Darwin struggled to explain how forty thousand bees working in the dark, seemingly by instinct alone, could organize themselves to construct something as perfect as a honey comb. How do bees accomplish such incredible tasks? Synthesizing the findings of decades of experiments, The Spirit of the Hive presents a comprehensive picture of the genetic and physiological mechanisms underlying the division of labor in honey bee colonies and explains how bees' complex social behavior has evolved over millions of years. Robert Page, one of the foremost honey bee geneticists in the world, sheds light on how the coordinated activity of hives arises naturally when worker bees respond to stimuli in their environment. The actions they take in turn alter the environment and so change the stimuli for their nestmates. For example, a bee detecting ample stores of pollen in the hive is inhibited from foraging for more, whereas detecting the presence of hungry young larvae will stimulate pollen gathering. Division of labor, Page shows, is an inevitable product of group living, because individual bees vary genetically and physiologically in their sensitivities to stimuli and have different probabilities of encountering and responding to them. A fascinating window into self-organizing regulatory networks of honey bees, The Spirit of the Hive applies genomics, evolution, and behavior to elucidate the details of social structure and advance our understanding of complex adaptive systems in nature.

It is also essential reading for physicians, health officials and community health workers.

Ripercorrere la storia della logopedia in Italia consente di inquadrare la scienza e gli interventi sanitari nel campo della comunicazione e della deglutizione. Le radici, le premesse e i primi tentativi di cura si ritrovano gia nelle antiche civilta, ma la nascita della comunicologia moderna risale a tempi molto piu recenti. Verso la fine dell Ottocento, in zona mitteleuropea, fanno la loro comparsa informale i primi adepti medici, i foniatri, e non medici, i logopedisti, ma bisognera aspettare la fine del secolo per trovare in questo campo posizioni accademiche e professionali definite. Il volume, oltre ad esporre la cronologia di fatti e avvenimenti, vuole percorrere sistematicamente la straordinaria evoluzione scientifico-epistemologica della logopedia, che a sua volta ha provocato importanti ricadute nei metodi di intervento sulla patologia. Una parte consistente riguarda poi gli attuali aspetti legati alle norme, la formazione e l esercizio della professione.

We shriek about them, slap and spray them, and generally think of insects (when we think of them at all) as pests. Yet, if all insects, or even a critical few, were to disappear--if there were none to pollinate plants, serve as food for other animals, dispose of dead organisms, and perform other ecologically essential tasks--virtually all the ecosystems on earth, the webs of life, would unravel. This book, the first to catalogue ecologically important insects by their roles, gives us an enlightening look at how insects work in ecosystems--what they do, how they live, and how they make life as we know it possible.

In "What Good Are Bugs?" Gilbert Waldbauer combines anecdotes from entomological history with insights into the intimate workings of the natural world, describing the intriguing and sometimes amazing behavior of these tiny creatures. He weaves a colorful, richly textured picture of beneficial insect life on earth, from ants sowing their "hanging gardens" on Amazonian shrubs and trees to the sacred scarab of ancient Egypt burying balls of cattle dung full of undigested seeds, from the cactus-eating caterpillar (aptly called "Cactoblastis") controlling the spread of the prickly pear to the prodigious honey bee and the "sanitary officers of the field"--the fly maggots, ants, beetles, and caterpillars that help decompose and recycle dung, carrion, and dead plants. As entertaining as it is informative, this charmingly illustrated volume captures the full sweep of insects' integral place in the web of life.

Combining breadth of coverage with detail, this logical and cohesive introduction to insect ecology couples concepts with a broad range of examples and practical applications. It explores cutting-edge topics in the field, drawing on and highlighting the links between theory and the latest empirical studies. The sections are structured around a series of key topics, including behavioral ecology; species interactions; population ecology; food webs, communities and ecosystems; and broad patterns in nature. Chapters progress logically from the small scale to the large; from individual species through to species interactions, populations and communities. Application sections at the end of each chapter outline the practicality of ecological concepts and show how ecological information and concepts can be useful in agriculture, horticulture and forestry. Each chapter ends with a summary, providing a brief recap, followed by a set of questions and discussion topics designed to encourage independent and creative thinking.

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.

Spiders are often underestimated as suitable behavioural models because of the general belief that due to their small brains their behaviour is innate and mostly invariable. Challenging this assumption, this fascinating book shows that rather than having a limited behavioural repertoire, spiders show surprising cognitive abilities, changing their behaviour to suit their situational needs. The team of authors unravels the considerable intra-specific as well as intra-individual variability and plasticity in different behaviours ranging from foraging and web building to communication and courtship. An introductory chapter on spider biology, systematics and evolution provides the reader with the necessary background information to understand the discussed behaviours and helps to place them into an evolutionary context. Highlighting an under-explored area of behaviour, this book will provide new ideas for behavioural researchers and students unfamiliar with spiders as well as a valuable resource for those already working in this intriguing field.

In Six-Legged Soldiers, Jeffrey A. Lockwood paints a brilliant portrait of the many weirdly creative, truly frightening, and ultimately powerful ways in which insects have been used as weapons of war, terror, and torture. He concludes with a critical analysis of today's defenses--and homeland security's dangerous shortcomings--with respect to entomological attacks.
Beginning in prehistoric times and building toward a near and disturbing future, the reader is taken on a journey of innovation and depravity. Lockwood, an award-winning science writer, begins with the use of "bee bombs" in the ancient world and explores the role of insect-borne disease in changing the course of major battles, from Napoleon's military campaigns to the trenches of World War I. He explores the horrific programs of insect weaponization during World War II: airplanes designed to drop plague-infested fleas, facilities rearing tens of millions of crop-devouring beetles, and prison camps where doctors tested disease-carrying lice on inmates. The Cold War saw secret government operations involving the mass release of specially developed strains of mosquitoes on an unsuspecting American public--along with the alleged use of disease-carrying and crop-eating pests against North Korea and Cuba. Lockwood reveals how easy it would be to use insects in warfare and terrorism today, pointing to how domestic eco-terrorists in 1989 extorted government officials and wreaked economic and political havoc by threatening to release the notorious Medfly into California's crops.
A remarkable story of human ingenuity--and brutality--Six-Legged Soldiers is the first comprehensive look at the use of insects as weapons of war, from ancient times to the present day.

A unique and critical analysis of the wealth of research conducted on the biology, biochemistry and chemical ecology of the rapidly growing field of insect cuticular hydrocarbons. Authored by leading experts in their respective fields, the twenty chapters show the complexity that has been discovered in the nature and role of hydrocarbons in entomology. Covers, in great depth, aspects of chemistry (structures, qualitative and quantitative analysis), biochemistry (biosynthesis, molecular biology, genetics, evolution), physiology, taxonomy, and ecology. Clearly presents to the reader the array of data, ideas, insights and historical disagreements that have been accumulated during the past half century. An emphasis is placed on the role of insect hydrocarbons in chemical communication, especially among the social insects. Includes the first review on the chemical synthesis of insect hydrocarbons. The material presented is a major resource for current researchers and a source of ideas for new researchers.
