'Darwin cleared: official' This 1982 Times (7 January) head line of a first leader, reporting the astonishing case brought in Arkansas against compulsory teaching of a biblical account of creation, hopefully set at rest doubts about Darwin in the minds of a public confused by media presentations of such unfamiliar concepts as punctuated equilibria, cladism and phenetics. Mud sticks, but Darwin's perturbed ghost may have found some consolation in the concurrent celebrations at Grange-over-Sands, a modest township in Cumbria, UK, of the centenary of the publication of his less controversial book The Formation of Vegetable Mould through the Action of Worms. In the form of a symposium on earthworm ecology, this attracted some 150 participants, predominantly adrenalin-charged research workers in the full heat of peer-group interaction. This book comprises a selection of the more ecologically oriented papers contributed to the symposium, brutally edited in the interests of brevity and thematic continuity. The book opens with an appraisal of Darwin's earthworm work in its historical and philosophical context and relates his views on 'vegetable mould' to current concepts of humus formation. Thereafter, quotations from Darwin made out of piety have been rigorously excluded. Subsequent sections each comprise a review chapter and two or three 'case studies' presenting new data on a related topic."

The brown recluse is a fascinating spider very well adapted to dwelling in houses and other buildings. Because of this very quality and the ghastly reputation associated with the medical consequences of its bite, it has become infamous throughout North America. Although recluse spiders can cause serious skin injuries and, in very rare cases, death, the danger posed by this spider is often exaggerated as a result of arachnophobia and the misdiagnosis of non-spider-related conditions as brown recluse bites. These misdiagnoses often occur in areas of North America where the spider does not exist, making legitimate bites improbable. One of the greatest factors that keeps the myths alive is misidentification of common (and harmless) spiders as brown recluses. With this book, Richard S. Vetter hopes to educate readers regarding the biology of the spider and medical aspects of its bites, to reduce the incidence of misdiagnoses, and to quell misplaced anxiety. In The Brown Recluse Spider, Vetter covers topics such as taxonomy, identification, misidentification, life history characteristics and biology, medical aspects of envenomations, medical conditions misdiagnosed as brown recluse bites, other spider species of medical consideration (several of which have been wrongly implicated as threats to human health), and the psychology behind the entrenched reasons why people believe so deeply in the presence of the spider in the face of strong, contradictory information. Vetter also makes recommendations for control of the spider for households in areas where the spiders are found and describes other species of recluse spiders in North America. Although The Brown Recluse Spider was written for a general audience, it is also a valuable source of information for arachnologists and medical personnel.

Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been sufficiently ironed out to permit students to master the manipulations in a few laboratory periods. Many specialized techniques are confined to one specific research labo ratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save con siderable time. It is the purpose of this series (1) to report new develop ments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe ex periments which might be applicable for use in biology laboratory courses."

Mention the words 'arthropod cuticle' to most biologists and they usually provoke a glazed expression. This is because the cuticle is commonly regarded as an inert substance. It is hoped that this book will dispel this fallacy. The study of cuticle in its proper context now involves many of the wider aspects of biology which are currently in vogue (e. g. how a hormone like ecdyson induces a specific enzyme like dopa decarboxylase; the unsolved major problem of cell gradient and polarity; the involvement of cyclic AMP in hormonal mechanisms; the extra cellular control of cuticular enzymes, of the mechanical proper ties of cuticle structural proteins, and of the orientation of fibrous molecules; and the relation of chromosome puffing to the synthesis of specific proteins). Studies on cuticle demand a variety of techniques, and examples of the following are illustrated in this book (fluorescence, phase contrast, polariza tion and Nomarski interference microscopy; infrared absorp tion; transmission and scanning electron microscopy; autora diography analyzed by electron microscopy; negative staining in the electron microscope; optical diffraction, high angle X-ray diffraction, low angle X -ray diffraction and selected area electron diffraction). I am well aware that the biophysical parts of this book are less incomplete than other aspects. A developmental biologist or a biochemist would have further elaborated other parts ofthe subject matter. Only one previous author, RICHARDS (1951)hasdevoted a book to arthropod cuticle."

The subject area embraced by the term "biological control" in its classical sense is very broad indeed. The term itself was apparently first used in 1919 by the late Harry S. Smith, and was then used specifically in reference to the suppression of insect populations by the actions of their indigenous or introduced natural enemies. The California school of biological control specialists who followed in Smith's footsteps have traditionally differentiated "natural" biological control (by indigenous natural enemies) and "applied" biological control (by man-introduced natural enemies). Subsequently, the philosophy broadened beyond the original narrow concern with population suppression of insects (and especially pest insects), to embrace directed activities against mites or other arthropod pests, various invertebrate and vertebrate pests, weeds, and organisms producing disease in humans or their domestic animals and plants. The techniques used in these activities also multiplied beyond the original concern with natural enemies. The subjects area discussed in this book is, at the same time, broader and more restricted than that covered in other books on "biological control. " On the one hand, the treatment here is restrictive in that, with rare exception, we have limited ourselves to dealing only with ideas and examples involving the suppression of insect pests through human activity or intervention in the environment.

In the comparative physiology of photoreception by the Protista and the invertebrates two aspects are emphasized: (1) the diversity of visual processes in these groups and (2) their bearing upon general mechanisms of photoreception. Invertebrates have evolved a far greater variety of adaptations than vertebrates modifications aiding survival in the remarkably different biotopes they occupy. The number of species in itself suggests this multiformity; each of them has peculiarities of its own, in morphology as well as in physiology and behavior. But these special adaptations are variations on a few great themes. Although the catalogue of invertebrate species is immense, the literature concerning them nearly rivals it in extent-even if one considers only that fraction dealing with visual physiology. Taxonomy proceeds by grouping the species, categorizing them in genera, families, orders, and progressively larger units. Similarly, comparative physiology aims at an analogous, more or less compre hensive, classification. This Part A of Volume VII/6, like Part B that follows it, emphasizes the broad questions that concern groups larger than the individual species; in some cases these questions have general applicability. The middle course between approaches that are too specialized and those that are too general is often elusive, but here we attempt to follow it. The vast number of special adaptations-probably, as we have said, as large as the number of species-is beyond the range even of a handbook."

The idea of holding an Advanced Study Institute (ASI) and getting a volume out, on the Nervous Systems in Invertebrates first cropped up in the summer of 1977 at the ASI on Sensory Ecology. I had prepared a review of the nervous systems in coelomates and noticed how much we depended on Bullock and Horridge's treatise on the one hand and how much new material and requirements has cropped up since 1965, when this classical work was published. Interest in the concerted study of pollution and environmental toxicology was growing in geometrical proportions and the use of invertebrates as indices was growing. As a teacher of a course on the biology of invertebrates since the beginning of my career I had also noticed how the interest of the students and the content of my course was shifting gradually and steadily from the traditional morphology-taxonomy type to the physiology-ecology-embryology orientation. Students were demanding to know the relevency of what they had to learn. Thus, after the ASI on Photoreception and Vision in Invertebrates held in 1982 the question of one on nervous systems was raised by a number of colleagues. It appeared then that the consensus was that the time was ripe to hold one and that it will be worthwhile. Therefore, as usual arrangements had to begin at least two years in advance. Most of the persons I contacted to lecture and write chapters on selected topics agreed enthusiastically.

Historecognition, broadly defined, spans the processes responsible for the regulation of the genetic integrity of self in the face of conspecific (allogeneic) and heterospecific (xenogeneic) nonself. The existence of precise historecognition systems in the invertebrates can be traced back to Bancroft's discovery in 1903 of, strain specific regulation of colony fusion in the compound ascidian Botryllus schlosseri, and Wilson's report in 1907 of species-specific sponge re-aggregation. Despite this provocative history, invertebrate historecognition remained largely unexplored for over half a century, while studies of vertebrate immune systems prospered. Then, in the 1970's, interest in invertebrate his tore cognition grew once again, this time cast largely in terms of understanding the mechanisms and evolutionary history of vertebrate immunity. From our current understanding of vertebrate immunity and invertebrate historecognition, three generalizations about their relationships can be drawn. First, despite substantial knowledge about the genetics and molecular biology of cell recognition in the context of vertebrate immunity and to a lesser extent of invertebrate historecognition, the evolutionary relationships between invertebrate self/nonself recognition and vertebrate immune systems remain obscure. Second, although vertebrate allograft recognition is of dubious functional significance itself (because intergenotypic cellular contacts are unusual, except during fertilization and pregnancy), natural allografts occur frequently as sedentary invertebrates grow and compete for living space. It is now known that the operation of invertebrate his tore cognition systems can profoundly affect the outcomes of competitive interactions by mediating allogeneic aggressive behavior and somatic fusion."

The literature is still one of our biggest frustrations to-day. There is, in one sense, too much of it, and in another not enough - for there are insufficient and inadequate published guidelines through this jungle. Last year two excellent books for students of ecological chemistry were published, one in France and one in England. The concordance of the references was a mere overall 3% rising to 7% in the chapters on pheromones. Even in the computer age, the channel remains a formidable barrier to the rapid exchange of biological information. At the present time we are in urgent need of compilations similar to John Feltwell's "The Large White Butterfly"; since the literature has become virtually unmanageable. This insect is now a demonstration object in the sixth form schoolroom; an experimental "rabbit" in the University laboratory; a test animal in virus and bacterial research projects; a tool for the study of flight mechanisms, migration, plant biochemistry, hormones, genetics, allergies, pigments, mimicry, etc. , etc. John Feltwell has, by this massive compilation, rendered us a great service - in fact he has given us a present of 4,000 hours of library time spent in 50 different libraries in seven countries. In the process he has collected 8000 references to the Large White. Of these, 4000 have been selected, and we are given a brief indication of their contents.

Most neurobiological research is performed on vertebrates, and it is only natural that most texts describing neuroanatomical methods refer almost exclusively to this Phylum. Nevertheless, in recent years insects have been studied intensively and are becoming even more popular in some areas of research. They have advantages over vertebrates with respect to studying genetics of neuronal development and with respect to studying many aspects of integration by uniquely identifiable nerve cells. Insect central nervous system is characterized by its compactness and the rather large number of nerve cells in a structure so small. But despite their size, parts of the insect eNS bear structural comparisons with parts of vertebrate eNS. This applies particularly to the organization of the thoracic ganglia (and spinal cord), to the insect and vertebrate visual sys tems and, possibly, to parts of the olfactory neuropils. The neurons that make up these areas in insects are often large enough to be impaled by microelectrodes and can be injected with dyes. Added to advantages of using a small eNS, into which the sensory periphery is precisely mapped, are the many aspects of insect behaviour whose components can be quan titized and which may find both structural and functional correlates within clearly defined regions of neuropil. Together, these various features make the insect eNS a rewarding object for study. This volume is the first of two that describe both classic and recent methods for neuroanatomical research on insect eNS."

The Sirex woodwasp, Sirex noctilio, is the most important invasive alien insect pest of Pinus plantations in the Southern Hemisphere. It now also threatens pines in North America. This book brings together the worldwide knowledge of researchers from Universities and Government institutions, as well as forest industry practitioners that have worked on the pest. Importantly, it is the first comprehensive treatment of the subject since S. noctilio was discovered outside its native range around 1900. The book covers all aspects of the biology and management of S. noctilio, including aspects of the insects' taxonomy, general life history, host-plant relationships, population dynamics, chemical ecology and symbiosis with the fungus Amylostereum areolatum. The book also contains a comprehensive synthesis of the history and current status of the pest and worldwide efforts to control it, including biological control, silviculture and quarantine.

This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Annelida, mainly consisting of marine Polychaeta and in faunal and partly parasitic Clitellata, is one the most significant metazoan taxa. Its more than 20.000 described species invade nearly all habitats and play a central role in marine benthic systems as well as in terrestrial soil communities. Annelids include all soft-bodied segmented worm-like organisms and have been recognized as a separate "phylum" for almost 200 years.

Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships.

The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.

In his preface to early editions of this book, the late Dr. A. D. Imms said that he intended it to be an elementary account of entomology as a branch of general biology. He had especially in mind the needs of university students of zoology and agriculture, as well as those intending later to specialize in entomology, and he suggested that the book might also interest teachers of advanced biology'in schools. These general aims and the balance between the different aspects of the subject have changed little in this and in our previous revision. We have, however, tried to bring the present edition up to date on the lines of our revised tenth edition of Imms' General Textbook of Entomology, published in 1977. The text has been entirely re-set and eleven illustrations have been replaced by new figures. The same orders . of insects are recognized as in the last edition, but the sequence in which the Endopterygote groups appear has been changed to reflect more accurately their probable evolutionary relationships. Many small changes and some addi tions have been made in the physiological sections, the chapter on the origin and phylogeny of insects has been rewritten, and a new bibliography provides a selection of modern references for the in tending specialist. It has been our object to make these alterations without materially increasing the length of the book or its level of difficulty."

The words pronounced by Serge Kreiter during the meeting come to mind. They could record exactly the situation of Acarology in Europe and in the World: "I think that in many European countries there are very few full time acarologists. It is very rare to have new positions available . . . . And public money, from the European Community but also from national countries, is very hard to get when you want to work on mites . . . . Could two acarological associations in Europe (Eur. A. Ac. and S. I. A. L. F) work together or, better, get married?" So, the fourth symposium of the European Acarologists has not only been the occasion to have an idea on which direction the research is addressed today, but also it pointed out the difficulties of our "scientific hranch." On the basis of the presentations and invited papers we had evidences of a "new" Acarology based on modern techniques and methods of investigations but also the importance, often sheltered even if of relevant value, of the "old" Acarology made on the alpha taxonomy and basic studies. So, a "new" Acarology needs the "old" one. In this context, the hope to put together the European acarologists has been coming up. This fact, of political meaning, can surely improve the acarological movement and the discussion on this point showed clearly the importance of several other activities and efforts in this direction. We hope that the meeting in Siena will represent a significative stone for the progress of Acarology.

In aquatic ecosystems, the oligochaetes are often a major component of the community. Their relevance in sediment quality assessment is largely related to their benthic and detritivorous life habit. In this book, we aim to present the state of the art of Pollution Biology using oligochaete worms in laboratory and field studies. Future research will require the combination of a variety of methodological approaches and the integration of the resulting information, avoiding fragmented and often conflicting visions of the relationships of the species with their environment. Current approaches to ecotoxicology and bioaccumulation using ecological risk assessment provide the opportunity to relate community studies with probability of effects. This book addresses three main themes: Ecological and Field Studies using the composition and structure of oligochaete communities, Toxicology and Laboratory Studies, and Bioaccumulation and Trophic Transfer Studies. Two appendices list values of toxicological parameters (LC50, EC50) and several bioaccumulation variables (bioaccumulation factors, biological half-life, toxicokinetic coefficients, and critical body residues) for different oligochaete species. Additional information is provided on Methodological Issues and on the Taxonomy of several oligochaete families, with information on the most recent taxonomic debates. Each chapter includes a critical view, based on the authors experience, of a number of current issues which have been raised in the literature.

Lacewings are predatory insects which attack and kill large numbers of insect pests. Lacewings in the Crop Environment addresses both the theoretical and practical aspects of lacewing biology and their use in crop protection. The book opens with a section on lacewing systematics and ecology. Next, lacewings as predators in a wide variety of commercially important crops are reviewed and this is followed by a section on the principles of using lacewings in pest control. The possible impact of genetically modified crops on lacewing populations is also discussed. Finally, a fascinating array of case studies of lacewing use in many crops from around the world is presented, and future uses of lacewings speculated upon. Lacewings in the Crop Environment is an essential reference work and practical handbook for students, researchers of biological control, integrated pest management and agricultural science, and for field workers using lacewings in pest management programmes worldwide.

Insect Conservation: A Global Synthesis is a landmark, field-defining work written by Professor Michael Samways, one of the founding fathers of this burgeoning discipline of conservation science. This book presents a state-of-the-art, comprehensive review of the entire field of insect conservation, from single-species conservation to whole-ecosystem approaches, and from natural ecosystems to the urban landscape. The variety and number of insects are truly vast. They are the most speciose group of organisms on Earth, with the majority barely known to science or still not described at all. They are a vital component in all terrestrial ecosystems, which would fail to function normally without them. Insect populations worldwide, however, are under threat. Human-mediated degradation of natural habitats, pollution, over-use of pesticides, and the spread of urbanization has led to the collapse of insect populations in many areas of the world. A growing recognition of the importance of insects in natural and agricultural systems has stimulated the development of an entire discipline dedicated to their conservation. Insect Conservation: A Global Synthesis is designed to be used by students of conservation biology and ecology, but also serves as an essential overview for professional entomologists with an interest in conservation, and for conservationists interested in insects. The book communicates on three levels: (i) through the text, with extensive references providing a gateway to the ever-increasing primary literature; (ii) through the extensive use of carefully constructed illustrations, with detailed captions which act to summarize the text and are complete in their own right; and (iii) through focused key points at the end of every chapter, which summarise the main learning points for students.

This is a comprehensive account of centipede biology providing a critical review of the work covering anatomy, behaviour, reproduction and life history, predators and parasites, physiology, ecology and taxonomy. It is an important source-book of particular value to scientists working directly with this group and to soil ecologists and those more generally interested in arthropods, arthropod affinities and their evolution. This is a book from an internationally respected scientist and includes many first-hand accounts of his own work both on temperate and tropical species.

Hemiptera - Heteroptera encompasses the three well-defined suborders of the true bugs which are adapted to an aquatic or littoral habitat. The book begins with a section on the biology these insects and provides illustrations of the basic features of their morphology and outlines the larval development. Brief outlines of the ecological and zoogeographical peculiarities of the three aquatic suborders are presented individually, and various methods for observing, collecting, preserving, rearing, and examining specimens are discussed.

Most of the book is devoted to keys for the identification of adults to species, and notes are provided that will help recognize the known larvae. Unlike most other aquatic insects, the larval instars of the heteropteran species closely resemble the adults in their morphology, preferred habitats, and feeding habits. Therefore, distinguishing features of those relatively few larvae which have been described in detail are usually mentioned in the keys to the adults rather than being included in separate keys. In addition to the most important features for determining the individual species, many keys include additional notes on the morphology, which is intended to give the user a better chance of recognizing specimens of species not yet known to science. After the currently recognized name of each species, the known range is provided. Regions of the world outside of South America, South American countries, and the states of Brazil from which the species has been reported are listed. Following the range information, major synonyms previously used for the species in the literature are provided. If subspecies have been described and are still recognized as such, they are also discussed. Finally, if the status of the species is regarded as uncertain because of a poor description, strong resemblance to another species, or any other reason, a note is added that a detailed study will be necessary to clarify the status of the taxon. Taxonomic revisions in the book itself are strictly avoided.

To provide the user of the keys with maximum assistance in making reliable identifications, the book is richly illustrated with pen and ink drawings of thousands of individual morphological structures arranged in 820 figures. The book is intended to make a significant impact toward popularizing the study of South American water bugs by assembling and condensing the information in hundreds of individual publications on the group, which appeared in many books and journals published in many different countries over the past 200 years. Some of these works are very difficult to obtain in South America, and their lack creates serious impediments to systematic, ecological, and zoogeographical research. In the more than 730 titles appearing in the bibliography, the original descriptions and revisions of almost all South American species can be found.

The most up-to-date and authoritative resource on the biology and evolution of solitary bees While social bees such as honey bees and bumble bees are familiar to most people, they comprise less than 10 percent of all bee species in the world. The vast majority of bees lead solitary lives, surviving without the help of a hive and using their own resources to fend off danger and protect their offspring. This book draws on new research to provide a comprehensive and authoritative overview of solitary bee biology, offering an unparalleled look at these remarkable insects. The Solitary Bees uses a modern phylogenetic framework to shed new light on the life histories and evolution of solitary bees. It explains the foraging behavior of solitary bees, their development, and competitive mating tactics. The book describes how they construct complex nests using an amazing variety of substrates and materials, and how solitary bees have co-opted beneficial mites, nematodes, and fungi to provide safe environments for their brood. It looks at how they have evolved intimate partnerships with flowering plants and examines their associations with predators, parasites, microbes, and other bees. This up-to-date synthesis of solitary bee biology is an essential resource for students and researchers, one that paves the way for future scholarship on the subject. Beautifully illustrated throughout, The Solitary Bees also documents the critical role solitary bees play as crop pollinators, and raises awareness of the dire threats they face, from habitat loss and climate change to pesticides, pathogens, parasites, and invasive species.

Designed as an introduction to the intriguing world of insect biology, this book examines familiar entomological topics in nontraditional ways. Author David B. Rivers gives important concepts relatable context through a pop culture lens, and he covers subjects that are not typical for entomology textbooks, including the impact of insects on the human condition, the sex lives of insects, why insects are phat but not fat, forensic entomology, and the threats that some insects pose to humanity. Each chapter presents clear and concise key concepts, chapter reviews, review questions following Bloom's taxonomy of learning, web links to videos and other resources, and breakout boxes (called Fly Spots) that capture student interest with unique and entertaining facts related to entomology. Focusing on both traditional and cutting-edge aspects of insect biology and packed with extensive learning resources, Insects covers a wide range of topics suitable for life science majors, as well as non-science students, including: * the positive and negative influences of insects on everyday human life* insect abundance* insect classification (here presented in the context of social media)* insect feeding, communication, defense, and sex* how insects are responding to climate change* forensic entomology* how insects can be used as weapons of war* how insects relate to national security* why insects have wings* how to read pesticide labels

Biocontrol is among the most promising methods for a safe, environmentally benign and sustainable crop protection. Microbial pesticides offer a great potential, and it is anticipated that they will become a substantial part of the use of all crop protection products. Their development and commercialization, however, has been difficult and with many failures. For the first time, a rational and structured roadmap has been designed for the development and commercialization of microbial pest control products, based on entomopathogenic bacteria, fungi, viruses and nematodes, for the control of arthropod pests. The emphasis lies on strain screening, product development, up to successful commercialization, from a bio-industry's viewpoint. The building blocks of the entire process are identified. The selection criteria for a microbial pest control agent are defined as well as critical parameters for the development of the product. Implementation of the product into an integrated pest management programme is pivotal for a substantial market uptake. Three phases are distinguished for successful adoption in the market: an appropriate application strategy, an optimal implementation strategy, and an effective adoption strategy. Key success and failure factors are identified. Registration is a major hurdle for biopesticides. Salient registration issues are treated and useful information presented. The road to a successful microbial pest control product is designed. Diagrams illustrate the stepwise approach of the entire process. A future perspective on the biopesticide market is presented with limiting and promotional factors and trends. The significant drivers for success are food safety concern, new research and technology, changes in the regulatory climate, and the occurrence of new invasive pests. This systematic roadmap with a strong focus on economics and market introduction will assist academic researchers and industrial developers of bi

Large parts of the continents are covered by a green blanket of living plants. From an insect's point of view this green blanket is not uniform, but consists of a mosaic of resources of variable quality and with various levels of noxious secondary compounds. It is the challenge of phytophagous insects to orientate and reproduce within this mosaic of resources and among hostile competitors and natural enemies. The International Symposia on Insect-Plant Relationships (SIP) provides fora where scientists from different fields (mainly in biology and chemistry) meet and discuss the most recent findings which contribute to our understanding of the complex interactions between plants and insects. The meetings seek to unravel basic mechanisms as well as applied aspects. It is recognized that human activities now have major influence on virtually all the world's ecosystems, and a better understanding of the dynamics of insect-plant interactions may be useful for development of new crop protection strategies and for coping with the threatening loss of biodiversity.

The 11th International Symposium on Insect-Plant Relationships (SIP11), held on August 4-10, 2001, in Helsingor, Denmark, followed the tradition of previous SIP meetings and covered topics of different levels from chemistry, physiology, and ethology to ecology, genetics, and evolution of insect-plant relationships. The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms. "

Acarology is on the move For a long time the development of Acarology as a field of biological science has been dominated by systematists and applied scientists. In the last 15 years, however, Acari have been increasingly recognized as highly suitable for the testing of theories in ecological and evolutionary sciences. The growing interest from evolutionary and molecular biologists and from population and community ecologists in mites and ticks has a strong impetus on the field of Acarology, and has already led to significant progress. This book contains many chapters that illustrate the recent progress in - mainly evolutionary and ecological aspects of - Acarology.
