Ecdysone is the steroidal prohormone of the major insect moulting hormone 20-hydroxyecdysone. It groups with its homologues the steroidal molting hormones in arthropods, but they also occur in other phyla where they can play different roles. Besides ecdysteroids appear in many plants mostly as protection agents (toxins or antifeedants) against herbivorous insects.

The important developments and achievements in modern ecdysone science since the first edition in 1989 by J. Koolman have led to this new revised, expanded and retitled reference work. New chapters in this edition include RNA interference, the ecdysone receptor crystal structures and structure activity relationships, etc. Each article may also be read independently, as a review of that particular subject.

Complete up-to-date coverage of many important topics - the book is divisible into five conceptual areas: (1) Distribution and diversity of ecdysteroids in the two kingdoms is still basis, (2) In the post-genomic era, ecdysteroid genetic hierarchies in insect growth and reproduction, (3) Role of cross talk of genes and growth factors in ecdysteroid titers and signaling, (4) Ecdysteroids function through nuclear and membrane receptors, and (5) Ecdysteroids in modern agriculture, medicine, doping and ecotoxicology. Each of the 23 chapters is written by scientists active in the reviewed research area and a truly distinguished international team of contributors has been chosen.

Ecdysone, Structures and Functions will be of immense use and contains essential information for scientists, students, and professionals alike in entomology, endocrinology, physiology, chemistry, and agricultural, plant, biomedicine and environmental sciences.

The PhyloCode is a set of principles, rules, and recommendations governing phylogenetic nomenclature, a system for naming taxa by explicit reference to phylogeny. In contrast, the current botanical, zoological, and bacteriological codes define taxa by reference to taxonomic ranks (e.g., family, genus) and types. This code will govern the names of clades; species names will still be governed by traditional codes. The PhyloCode is designed so that it can be used concurrently with the rank-based codes. It is not meant to replace existing names but to provide an alternative system for governing the application of both existing and newly proposed names. Key Features Provides clear regulations for naming clades Based on expressly phylogenetic principles Complements existing codes of nomenclature Eliminates the reliance on taxonomic ranks in favor of phylogenetic relationships Related Titles: Rieppel, O.

The psychological connections between humans and insects are tantalizing and complex. Through both evolutionary associations and cultural representations, insects have deeply infested our minds. They frighten, disgust, and sometimes enchant us. Whatever the case, few of us are ambivalent in the face of wasps, cockroaches, spiders, maggots, crickets or butterflies. They arouse terror, nausea, fascination-but rarely, if ever, indifference. And the costs of fear can be high, both in terms of the quality of individual lives and with regard to our social responses, from soaking our food with insecticides to overlooking our dependence on the ecological roles of insects (including those on the brink of extinction). The book is an examination of what scientists, philosophers, and writers have learned about the human-insect relationship. Jeffrey Lockwood is an entomologist himself and yet still experiences bouts of entomophobia; in fact, his seemingly paradoxical response to certain insects and scenarios is what prompted him to write this book. The book explores the nature of anxiety and phobia and the line between them. It examines entomophobia in the context of the nature-nurture debate, posing the question: how much of our fear of insects can be attributed to our ancestors' predisposition to avoid insects to benefit their own survival, and how much is learned through parents? Using his own and others' experiences with entomophobia as case studies, Lockwood breaks down common reactions to insects, distinguishing between fear and disgust, and inviting the reader to consider his/her own emotional, cognitive, and physiological reactions to insects in a new light.

The book is a taxonomic treatise of the tropical fruit flies of Papua New Guinea, Indonesian Papua, associated islands and Bougainville, the region of the world where speciation in the sub-family Dacinae has been most prolific. The book aims to provide readers with an updated record of all known species of Dacinae that occur in this geographic area including descriptions of 65 new species out of an entire list of 296 known species covered. It provides a discussion on the evolutionary origins of the Dacinae and a key to the genera and sub-genera recorded in the Australian-Pacific Region. Further, the major pest species and their biosecurity risks to other countries are discussed. Extensive field research by the authors and colleagues over many years has resulted in the accumulation of advanced knowledge of the tropical fruit flies in this region. - Records 296 known species - Descriptions and artwork of 65 new species - Discusses the evolutionary origins of the Dacinae - Provides a key to the genera and sub-genera in the Australian-Pacific A key reference for researchers of taxonomy, ecology and pest management in the family Tephritidae worldwide. Useful for biosecurity and horticulture workers in Agriculture Departments within government administration and universities around the world.

In Britain and Ireland there are about ten times more species of solitary bee than bumblebee and honeybee combined, yet the solitary bees tend to be ignored and we know much less about them. They are a fascinating, attractive and diverse group that can be found easily in a wide range of habitats, both urban and rural, and they are important as pollinators. Solitary bees provides an introduction to the natural history, ecology and conservation of solitary bees, together with an easy-to-use key to genera. Chapters cover: Diversity and recognition; Bee lives; Cuckoos in the nest; Bees and flowers; The conservation of solitary bees; Approaches to practical work; Keys to the genera of bees of the British Isles - Females and Males; and References and further reading.

In the English edition of his landmark book Endosymbiosis of Animals with Plant Microorganisms (1965), Professor Paul Buchner, probably the most prominent founder of systematic symbiosis research, wrote: ?I too soon fell victim to the spell of this subject, and from 1911 on devoted myself to it.? Almost half a century later, a growing number of entomologists are recognizing the impact that arthropod-bacteria symbiosis has on virtually all aspects of the biology of both host and symbiont. The discussion of this subject tends to be system based, with primary emphasis on the insect host. However, recent screening studies have revealed that the diversity of bacteria associated with arthropods may not be as wide as initially expected, and some genera are constantly being found in hosts that belong to distantly related taxa.

Manipulative Tenants: Bacteria Associated with Arthropods introduces the fascinating world of bacteria-arthropod associations with an emphasis on the bacterial partner. Written by an interdisciplinary team of international contributors, this book provides an overview of the diversity of bacterial symbionts identified to date as frequent partners of terrestrial arthropods. It discusses primary (obligatory) symbionts as well as the most abundant secondary (facultative) symbionts currently known.

Summarizing the most up-to-date information available on each symbiont, the book presents a synopsis of the field from the bacterial angle. Chapters examine Proteobacteria, including Sodalis and Wigglesworthia in tsetse flies and Stammerula and other symbiotic bacteria in fruit flies, as well as Bacteroidetes such as Blattabacterium and Cardinium. The book also identifies questions that emerge from the study of these systems. This comprehensive reference introduces the topic of bacteria-arthropod associations to researchers who are not familiar with it, enlarges the scope of knowledge of those who are, and provides a textbook for students in microbiology and other branches of biology.

The Atlas of Drosophila Morphology: Wild-type and Classical Mutants is the guide every "Drosophila" researcher wished they had when first learning genetic markers, and the tool they wish they had now as a handy reference in their lab research. Previously, scientists had only poor-quality images or sketches to work with, and then scattered resources online - but no single visual resource quickly at their fingertips when explaining markers to new members of the lab, or selecting flies to do their genetic crosses, or hybrids.

This alphabetized guide to "Drosophila" genetic markers lays flat in the lab for easy referencing. It contains high-resolution images of flies and the appropriate marker on the left side of each page and helpful information for the marker on the facing page, such as symbol, gene name, synonyms, chromosome location, brief informative description of the morphology, and comments on marker reliability. A companion website with updated information, useful links, and additional data provided by the authors complements this extremely valuable resource.

Provides an opening chapter with a well-illustrated introduction to "Drosophila" morphology

Features high-resolution illustrations, including those of the most common markers used by "Drosophila" researchers

Contains brief, practical descriptions and tips for deciphering the phenotype

Includes material relevant for beginners and the most experienced fly pushers

Omnipresent in virtually all terrestrial ecosystems and of undisputed ecological and economical importance, the study of social insects is an area that continues to attract a vast number of researchers. As a consequence, a huge amount of information about their biology and ecology has accumulated. Distilling this scattered information into a highly focused reference, Food Exploitation by Social Insects: Ecological, Behavioral, and Theoretical Approaches unites traditional behavioral and ecological studies with theoretical and mathematical models.

The book covers foraging ecology and behavior of social insects, their communication mechanisms, and theoretical models of important aspects. It examines two different but inseparably interlaced levels of social insect foraging: the macroscopic or colony level and the microscopic or individual level. The chapters include discussions of foraging decisions, patterns and strategies of social insect colonies, and information use and information transfer between workers. The book provides examples of how this biological knowledge can be used as a basis for the construction of mathematical and neural network models that in return may increase understanding of social insect foraging.

The contributors provide a fresh look on their topics, covering a wide range of subjects and recent scientific developments that are unprecedented in breadth and depth. The coverage of ants, bees, and wasps in one resource is a unique feature of the book. This taxonomic content combined with the variety of research approaches, allows the book to provide deeper insight into the subject.

Every science, including the study of insects, may have circumscribed limits, but its deeper principles open up new worlds of possibility. Milward uncovers these hidden principles by examining the daily lives and habits of insects. His studies lead him to fascinating speculations, taking the reader into the realms not only of literature, as suggested by the subtitle, but also of philosophy and theology.

When Milward discusses what everybody knows about insects and what he has personally observed, he relates insects to human life in general. His insights help us feel a certain fellowship with the insects, or at least with some of the more familiar insects. He does not let us forget that there is an important diff erence between human beings and insects. Human beings think. It is our ability to think that makes us what we are, but it is thinking that enables us to discover our affi nity with insects.

"The Secret Life of Insects" does not probe into the hidden lives of insects or treat them as individuals. His main interest is the light insects may throw on our human experience, and the assistance they may lend us as we seek to transcend our human experience. Milward aims at the level of common knowledge. In contrast to entomological scientists, Milward finds shadowy glimpses of hidden meaning in the insect world. Th ese intimations or shadowy glimpses reveal thoughts and possibilities that will extend the human imagination. As a consequence, this work will inspire philosophers, as well as general readers interested in refl ecting on the profundity of ordinary life.

The Leafcutter Ants is the most detailed and authoritative description of any ant species ever produced. With a text suitable for both a lay and a scientific audience, the book provides an unforgettable tour of Earth's most evolved animal societies. Each colony of leafcutters contains as many as five million workers, all the daughters of a single queen that can live over a decade. A gigantic nest can stretch thirty feet across, rise five feet or more above the ground, and consist of hundreds of chambers that reach twenty-five feet below the ground surface. Indeed, the leafcutters have parlayed their instinctive civilization into a virtual domination of forest, grassland, and cropland from Louisiana to Patagonia. Inspired by a section of the authors' acclaimed The Superorganism, this brilliantly illustrated work provides the ultimate explanation of what a social order with a half-billion years of animal evolution has achieved."

This Naturalists' Handbook aims to attract more people to the study of solitary wasps by describing the ecology, distribution and natural history of these insects, including all relevant research in one convenient volume. Contents include an overview of the natural history of the solitary wasp, guidelines on identification, and advice on techniques and approaches to study. Further reading, a systematic checklist of genera and an alphabetical checklist of species and their distributions are included. Detailed keys to the identification of the species form the centre of the book and the text is accompanied by clear illustrations throughout, making this an invaluable practical guide for anyone seeking to broaden their knowledge of these fascinating, diverse creatures. Smaller, gentler and less intimidating than the black and yellow social wasps, the solitary wasps are attractive because of their bright colours and their fascinating behaviour. A female wasp will construct a nest, excavating it from wood or sand or building it from mud. She provisions the nest with prey, hunting down a suitable creature, perhaps a caterpillar or a fly, which she will paralyse before dragging it home to the nest. She lays her egg on the paralysed prey, and the larva when it hatches feeds on the prey. On a sunny day it is easy to observe the apparently purposeful behaviour of female wasps as they prepare their nests and stock them with food for the next generation. This book is a digital reprint of ISBN 0-85546-295-7 (1995). Naturalists' Handbooks encourage and enable those interested in natural history to undertake field study, make accurate identifications and to make original contributions to research.
