Originally published in 1954, this book argues that the metamorphosis of insects is just a 'particularly striking example of the polymorphism which is universal among animals'. Wrigglesworth includes a number of black and white photographic plates of insects in various stages of growth and metamorphosis to illustrate key points in his argument. This book will be of value to anyone with an interest in the history of entomology.

The present work deals with the diseases of nematodes. Although the term disease implies a pathological condition brought about by an infectious agent, a broader concept is used here.

First published in 1921, this book is the second of a three-part study on Diptera, or two-winged flies. Pearce includes advice on the capture and study of entomological samples, and the majority of the volume is made up of detailed photos of various species of two-winged flies, both male and female, as well as the eggs and habitats of certain breeds. This book will be of value to anyone with an interest in scientific photography or the history of entomology.

Bees are flying insects of the order Hymenoptera closely related to wasps and ants. The ancestors of bees are assumed to be predatory wasps, which switched to pollen consumption. Further, bees co-evolved with flowering plants and divided into several species according to climatic conditions. Widely known bees are western bees Apis mellifera, and eastern bees Apis cerana. This book sheds light on features of evolution, phylogenesis, speciation, adaptation to environment, and taxonomy of bees. It will be of particular relevance to evolutionists, geneticists, taxonomists, ecologists, population geneticist, and breeders.

This book is a snapshot of the current state of the art of research and development on the properties and characteristics of silk and their use in medicine and industry. The field encompasses backyard silk production from ancient time to industrial methods in the modern era and includes an example of efforts to maintain silk production on Madagascar. Once revered as worth its weight in gold, silk has captured the imagination from its mythical origins onwards. The latest methods in molecular biology have opened new descriptions of the underlying properties of silk. Advances in technological innovation have created silk production by microbes as the latest breakthrough in the saga of silk research and development. The application of silk to biomaterials is now very active on the basis of excellent properties of silks including recombinant silks for biomaterials and the accumulated structural information.

This classic work by F. W. L. Sladen (1876 1921) was published in 1912. Captivated by the bees in the grounds of his home, he produced his first essay on them in 1892, and later began to keep bees and produce honey as a livelihood, at the same time studying and breeding honeybees. Moving in 1912 to Canada, he eventually received the title of Dominion Apiarist, but unfortunately his work was cut short by his sudden death in 1921. When this book was published, there were no detailed accounts of the life cycles of the humble-bee (or bumblebee) species. Sladen provides these, with a guide to distinguishing the different British species (with colour plates which can be viewed at http: //www.cambridge.org/9781108075725), and instructions on how to domesticate these important pollinators. Combining the enthusiasm of a naturalist with the precision of a scientist, this work is of continuing interest and importance in environmental studies."

Cephalopods are generally regarded as the most intelligent group among the invertebrates. Despite their popularity, relatively little is known about the range and function of their cognitive abilities. This book fills that gap, accentuating the varied and fascinating aspects of cognition across the group. Starting with the brain, learning and memory, Part I looks at early learning, memory acquisition and cognitive development in modern cephalopods. An analysis of the chambered nautilus, a living fossil, is included, providing insight into the evolution of behavioural complexity. Part II surveys environmental responses, especially within the active and learning-dependent coleoids. The ever-intriguing camouflage abilities of octopus and cuttlefish are highlighted, alongside bioluminescence, navigation and other aspects of visual and cognitive competence. Covering the range of cognitive function, this text underscores the importance of the cephalopods within the field of comparative cognition generally. It will be highly valuable for researchers, graduates and senior undergraduate students.

Recent research has focused attention on the importance of intrinsic antiviral immunity, i.e. immunity mediated by factors that are constitutively expressed in many cells. In this volume, leading experts provide a comprehensive overview of this relatively new and rapidly evolving field. They cover intrinsic proteinaceous antiviral immune effectors, such as the APOBEC3 and TRIM protein families as well as Tetherin and SAMHD1, which were initially discovered by researchers studying HIV-1. Furthermore, the role of RNA interference in antiviral defense in plants and invertebrates, as well as the interplay between microRNAs and viruses in mammalian cells, are analysed. One chapter discusses how intrinsic immunity and viral countermeasures to intrinsic immune effectors drive both pathogen and host evolution, and finally the emerging evidence that DNA damage response proteins restrict infection by DNA viruses is highlighted.

This volume provides a comprehensive selection of recent studies addressing insect hearing and acoustic communication. The variety of signalling behaviours and hearing organs makes insects highly suitable animals for exploring and analysing signal generation and hearing in the context of neural processing, ecology, evolution and genetics. Across a variety of hearing species like moths, crickets, bush-crickets, grasshoppers, cicadas and flies, the leading researchers in the field cover recent scientific progress and address key points in current research, such as: - How can we approach the evolution of hearing in insects and what is the developmental and neural origin of the auditory organs? - How are hearing and sound production embedded in the natural lifestyle of the animals, allowing intraspecific communication but also predator avoidance and even predation? - What are the functional properties of hearing organs and how are they achieved at the molecular, biophysical and neural levels? - What are the neural mechanisms of central auditory processing and signal generation? The book is intended for students and researchers both inside and outside of the fascinating field of bioacoustics and aims to foster understanding of hearing and acoustic communication in insects.

Originally published in 1914 as part of the Cambridge Nature Study Series, and intended as a guide for teachers and students, this book examines the types of animals found in British ponds. The text is illustrated by photographs and illustrations of aquatic insects and the necessary equipment for fieldwork, and includes suggested experiments and questions for discussion. This book will be of value to anyone with an interest in the history of education or British fauna.

First published in 1923, as the second edition of a 1916 original, this book presents a practical introduction to farm and garden pests. The text was was written to provide a guide to the more common pests affecting crops so that market gardeners and farmers could increase their yields. Numerous illustrative figures are included, together with appendices. This book will be of value to anyone with an interest in insects, agriculture and the history of science.

This atlas contains 189 coloured images taken from transversal, horizontal and sagittal sections of eleven organisms widely used in university teaching. Six invertebrate and five vertebrate species – from the nematode worm (Ascaris suum) to mammals (Rattus norvegicus) – are shown in detailed images. Studying the macrosections with unaided eyes, with a simple magnifier or binocular microscope might be of great help to accomplish traditional anatomical studies and to establish a certain spatial experience/space perception. This volume will be of great interest for biology students, researchers and teachers of comparative anatomy. It might act as supporting material of practical courses. Furthermore, medical practitioners, agricultural specialists and researchers having an interest in comparative anatomy might also benefit from it.

Machine learning is a novel discipline concerned with the analysis of large and multiple variables data. It involves computationally intensive methods, like factor analysis, cluster analysis, and discriminant analysis. It is currently mainly the domain of computer scientists, and is already commonly used in social sciences, marketing research, operational research and applied sciences. It is virtually unused in clinical research. This is probably due to the traditional belief of clinicians in clinical trials where multiple variables are equally balanced by the randomization process and are not further taken into account. In contrast, modern computer data files often involve hundreds of variables like genes and other laboratory values, and computationally intensive methods are required. This book was written as a hand-hold presentation accessible to clinicians, and as a must-read publication for those new to the methods.

For the first time in limnofaunistic bibliography, the present taxonomic knowledge about the different clades of chelicerata having adapted to an aquatic or amphibious lifestyle along various evolutionary pathways is brought together in an overview for the Central-European fauna. A total number of 746 taxa is covered, over 99 % of these at species level. In Volume 7/2-1 altogether 211 species are treated - 70 species of spiders, 7 species of Astigmata (3 of which to be identified only at family, genus, resp. species group level), 17 species of Oribatida, 27 species and one subspecies of Halacaridae, 45 species of terrestrial Parasitengona (4 of which to be identified only at genus level) and 45 species of Hydrachnidia (4 Stygothrombioidea, 3 Hydrovolzioidea, 16 Hydrachnoidea and 22 Eylaoidea). Volume 7/2-2 deals with 179 species of Hydrachnidia (58 Hydryphantoidea and 121 Lebertioidea). This third volume (Volume 7/2-3) includes taxonomic keys and ecological information for 355 species of the two highly diverse Hydrachnidia superfamilies Hygrobatoidea (241 species and one subspecies) and Arrenuroidea (113 species). The chelicerata volumes of this series are a basic tool for all limnologists interested in diversity and ecology - in particular for biologists investigating the ecotones between ground and surface water, between bottom substrata and open water, and between water and land.

First published in 1948 as the second edition of a 1931 original, this book deals with the main types of insects found on British farms, the damage they can cause and the various weeds that can harbour them. The text is richly illustrated with photographs and drawings of the insects, their eggs and the symptoms of their attack on common farm plants. This book will be of value to anyone with an interest in the history of entomology.

This book will be of value to anyone with an interest in entomology.

Insect Metamorphosis: From Natural History to Regulation of Development and Evolution explores the origin of metamorphosis, how it evolved, and how it is it regulated. The book discusses insect metamorphosis as a key innovation in insect evolution. With most of the present biodiversity on Earth composed of metamorphosing insects-approximately 1 million species currently described, with another 10-30 million still waiting to be discovered, the book delves into misconceptions and past treatments. In addition, the topic of integrating insect metamorphosis into the theory of evolution by natural selection as noted by Darwin in his On the Origin of Species is also discussed. Users will find this to be a comprehensive and updated review on insect metamorphosis, covering biological, physiological and molecular facets, with an emphasis on evolutionary aspects.

Global warming and globalization are the buzzwords of our time. They have nearly reached a religious status and those who deny their existence are considered modern heretics. Nevertheless, the earth has become an overcrowded village, traversable within a single day. Thus it is hardly surprising that besides persons and goods also agents of disease are easily transported daily from one end of the world to the other, threatening the health and lives of billions of humans and their animals. Agents of diseases (prions, viruses, bacteria, fungi and parasites) are not only transmitted by body contact or direct exchange of bodily fluids, but also by means of vectors which belong to the groups of licking or blood-sucking arthropods (mites, ticks, insects) that live close to humans and their houses. Without a doubt the recently accelerating globalization supports the import of agents of disease into countries where they never had been or where they had long since been eradicated, leading to a false sense of living on a "safe island." These newly imported or reintroduced diseases - called "emerging diseases" - may lead to severe outbreaks in cases where the countries are not prepared to combat them, or in cases where viruses are introduced that cannot be controlled by medications or vaccines. Arthropods are well known vectors for the spread of diseases. Thus their invasion from foreign countries and their spreading close to human dwellings must be blocked everywhere (in donor and receptor countries) using safe and effective measures. This book presents reviews on examples of such arthropod-borne emerging diseases that lurk on the fringes of our crowded megacities. The following topics show that there is an ongoing invasion of potential vectors and that control measures must be used now in order to avoid disastrous outbreaks of mass diseases.

The book consists of multiple chapters by leading experts on the different aspects in the unique relationship between arthropods and plants, the underlying mechanisms, realized successes and failures of interactions and application for IPM, and future lines of research and perspectives. Interesting is the availability of the current genomes of different insects, mites and nematodes and different important plants and agricultural crops to bring better insights in the cross talk mechanisms and interacting players. This book will be the first one that integrates all this fascinating and newest (from the last 5 years) information from different leading research laboratories in the world and with perspectives from academia, government and industry.

Fleas are one of the most interesting and fascinating taxa of ectoparasites. All species in this relatively small order are obligatory haematophagous (blood-feeding) parasites of higher vertebrates. This book examines how functional, ecological and evolutionary patterns and processes of host-parasite relationships are realized in this particular system. As such it provides an in-depth case study of a host-parasite system, demonstrating how fleas can be used as a model taxon for testing ecological and evolutionary hypotheses. The book moves from basic descriptive aspects, to functional issues and finally to evolutionary explanations. It extracts several general principles that apply equally well to other host-parasite systems, so it appeals not only to flea biologists but also to 'mainstream' parasitologists and ecologists.
