Chrysomelidae, along with Curculionidae and Bruchidae, are the most important phytophagous Coleoptera. At least 37,000 species of leaf beetles belonging to 19 subfamilies have now been described, and more probably remain to be discovered, especially in the tropics. Many species are familiar agricultural pests. The Colorado potato beetle, the cereal beetle, flea beetle and the corn root worms are but a few of the well known pests. Because of the economic importance and biological diversity, chrysomelids are an important taxonomic group for scientific inquiry. This book is divided into eight parts, entitled palaeontology, larvae and larval biology, trophic selection, genetics and evolution defence mechanisms, anatomy and reproduction, pathogens and natural enemies, and general studies in biology. The biologies of agricultural and forestry pests, Leptinotarsa, Plagiodera, Entomoscelis, Paropsis, Mecistomela and Aspidomorpha are dealt with in detail. Others, such as Timarcha and those in the poorly known Megalopodinae, are covered in Part VIII. In this volume the American, European, Asian and Australian fauna occupy the greatest part. This volume, together with Biology of Chrysomelidae (1988), provides a comprehensive coverage and helps to complete the picture of chrysomelid biology.

As in most groups of insects, scientific research on the Chrysomelidae began in Europe in 1758, with the description of a few genera and species by the Scandinavian entomologists C. von Linne, I.C. Fabricius, and others. As the 19th century dawned, many systematic entomologists took up the study of chrysomelid beetles, together with other groups of beetles, and many new species and genera were described from all parts of the world. This trend has, of course, continued down to the present time. However, researches on the Chrysomelidae did not remain restricted to systematics, and many new lines of study have been followed, especially in the present century, by workers who have benefitted from the advances made in related fields of pure and applied entomology. Much has been achieved in the study of the Chrysomelidae, as elsewhere, and it is the aim of the present book to provide a summary and guide to these achievements. It is also to be expected that this book will provide a stimulus for further studies on the Chrysomelidae, so that we can anticipate continuing progress in our knowledge and understanding of this group through the endeavours of an ever-increasing number of scientists. I offer my congratulations to all concerned in the preparation of this book and my best wishes for its success.

This book summarizes what is actually known about the biology of Leaf Beetles. It is the most recent study in the field. As we are well aware, Chrysomelidae, one of the three largest families of beetles, are of great economic importance since they can be a serious pest to crops or, on the other hand, can be used to destroy imported weeds. This is due to the selectivity of their feeding preferences. In this way, Chrysomelidae are an invaluable tool for studying plant selection mechanisms. The many and varied topics dealt with in this book cover almost all aspects of phylogeny, classification, paleontology, parasitology, biogeography, defenses, population biology, genetics and biological control as well as many other subjects. The most renowned specialists in these fields have been chosen to put together a diverse, state-of-the-art publication. Few beetle families have been studied in such detail as the Chrysomelids. This is not only due to their economic importance, but also to their incredible variety of forms and behaviors. There are no less than 40,000 species currently in existence worldwide, but probably 100,000 species have existed since the Jurassic, when they first came into being with the Cycadoids and other primitive plant families, later to diversify during the Cretaceous with the advent of flowering plants.

There are an estimated 40,000 species of chrysomelids, or leaf beetles, worldwide. These biologically interesting and often colorful organisms, such as the tortoise beetles, have a broad range of life histories and fascinating adaptations. For example, there are chrysomelids with shortened wings (brachypterous) and elytra (brachelytrous), other species are viviparous, and yet other leaf beetles have complicated anti predator-parasitoid defenses. Some species, such as corn rootworms (several species in the genus Diabrotica) constitute major agricultural crop pests. Research on Chrysomelidae 1 is a the first of an intended series of volumes on the Chrysomelidae edited by Jolivet, Santiago-Blay, and Schmitt.

This book, intended for the scientific community involved in biological control and integrated pest management, commercial companies producing biological control agents, risk assessors and regulatory authorities, compiles the current methodologies used for assessing the environmental impacts of invertebrate biological control agents and guidelines in performing science-based risk assessments required for the future regulation of such organisms.

"Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

"This book provides a comprehensive review of current knowledge of this insect pest and how it might be managed both in North America and in Europe. Comparisons are drawn between plant protection techniques currently applied in North America and their potential application in Europe. Cultural, biotechnical and biological control measures are also addressed, as are ecological baseline data such as population dynamics of the pest in North America and Europe, economic thresholds and aspects of its behaviour. This book will be of significant interest to those working in the areas of entomology and integrated crop protection throughout the world."--BOOK JACKET.

In the past years, much work has been carried out on either life-history evolu tion or structure and function of food webs. However, most studies dealt with only one of these areas and often touched upon the other only marginally. In this volume, we try to synthesize aspects of both disciplines and will concen trate on how the interactions between organisms depend on their life-history strategies. Since this is a very comprehensive topic, this volume will focus on vertical interactions to remain within a clearly arranged field. We present some scenaria based on life-history variation of resource and consumer, and show how particular patterns of life-history combinations will lead to particular patterns in trophic relationships. We want to deal with the selective forces underlying these patterns: the degree of specificity of the consumers deter mines the dependence on its resource, and its adaptation to the spatial and temporal availability of the resource. In this respect, the spatial structure of the resource and its "quality" may play an important role. The impact of natural enemies is another important selective force which may influence the evolu tion of interactions between species and the structure of communities. Here, the acquirement of an enemy-free space may provide selective adavantages. The importance of the impact of enemies is also expressed by the development of numerous and sometimes very subtle defense strategies. This will be dem onstrated especially for various aspects of chemical ecology.

One of the world's most insightful writers on the subject brings together an array of important and readable information on the ways in which insects and plants coexist in nature. Interrelationship Between Insects and Plants is a rare and expansive look at the intertwining of these two vastly different species. Its aim is to summarize in a simple a
