In 1980, the International Symposium on the Ecology of Bruchids Attacking Legumes (Pulses), organized by Dr. Labeyrie, was held at Tours, France. Since then, there has been tremendous progress in the area of Bruchid and Legume research. At the same time, as we face the problems of world-wide population explosion and food shortage, the importance of legumes as the world's major protein source is rapidly increasing, especial ly in tropical regions. Thus, it seemed appropriate to hold the Second Symposium in order to review the recent progress in the control of Bruchids and in the biology and ecology of Bruchids and legumes. This is an important part of the search for ways to integrate these fields with a common perspective. The Second International Symposium on Bruchids and Legumes (ISBL-II) was held in September 6-9, 1989 at Okayama, Japan under the joint auspices of the Japanese Society of Applied Entomology and Zoology and of the Foundation for Advancement of International Science. Significant contributions have originated in Japan on the study of Bruchid and legumes. Most notably, the study on population ecology by Professor S.

The papers in this book are organized as follows: insect-plant communities, host-plant selection, genetics and evolution, host-plant resistance and application of transgenic plants, and multitrophic interactions. Besides seven invited papers and a paper with concluding remarks, this volume also contains the short communications of all 115 oral presentations and posters. Included, too, are the summaries of four European Science foundation workshops held over the past two years, where European scientists discussed the state of the art and the future of major topics in insect-plant interactions in order to develop better integrated research programmes. The field of insect-plant interactions nowadays includes almost all of biology, as well as parts of chemistry and physics. It takes a central position in biology because insects are the most abundant animal group, half of them are herbivores and they dominate all terrestrial ecosystems. Knowledge of insect-plant interactions is thus fundamental to an understanding of the evolution of life on Earth. Two major topics of world-wide concern give this field an extra dimension.First, large amounts of food crops are still lost due to insect pests. With the increasing concern for environmental pollution and the subsequent plans to drastically reduce pesticides, integrated pest management and development of resistant crops become a major focus in agriculture. The importance of the study of insect-plant relationships is thus continuously augmented. Clearly, successful pest control demands sufficient fundamental knowledge of post-host interactions. Second, such work can contribute towards stopping or even counterbalancing the threatening biodiversity crisis thanks to an understanding of how the interaction of insects and plants has influenced and still influences the diversification and speciation (evolution) of both groups. These problems should, of course, be approached at a multitrophic level.

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.

Skickas inom 10-15 vardagar
Recent studies have shown that genetic polymorphisms play an important role in structuring the seasonal life cycles of insects, complementing an earlier emphasis on the effects of environmental factors. This book presents current ideas and recent research on insect life-cycle polymorphism in a series of chapters, covering the full breadth of the subject in order to give a view of how life-cycles are controlled and how they evolve. By consolidating our view of insect life-cycle polymorphism in this way, the book aims to provide a starting point for further enquiries. The volume should be of interest to a variety of entomologists and other biologists interested in the control and evolution of life cycles and in understanding the complex ecological strategies of insects and other organisms.

This scientific monograph deals with coccinellids (ladybirds), a group of beetles which are beneficial predators of aphids, scale insects and mites, and are also one of the most popular insects. This volume is an updated and modified version of "Biology of Coccinellidae" (1973). While the information goes into enough detail for a researcher or university teacher, the book should also be easily readable for the naturalist who is interested in the background behind the observed phenomena. Extension agriculture specialists should find ths text a friendly guide to the use of coccinellids in integrated pest management and biological control.

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 in mites and ticks, from evolutionary and molecular biologists and from population and community ecologists, has had a strong impetus on the field of acarology. This book contains many chapters that illustrate the recent progress in the mainly evolutionary and ecological aspects of acarology.

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 a platform for scientists from different fields (mainly in biology and chemistry) to meet and discuss the most up-to-date 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. This 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 information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms.

This volume is an updated and modified version of Biology of Coccinellidae (1973) 250 pp. Due to a vast increase in information, the book has become more voluminous (xvi + 464 pp. comprising 133 tables, 95 figures, 11 plates, 1692 references). While the information goes into enough detail for a researcher or university teacher, the book should also be easily readable for the naturalist who is interested in the background behind the observed phenomena. Extension agriculture specialists will find a friendly guide to the use of coccinellids in integrated pest management and biological control. The authors hope that the volume will thus help to make our environment safer both for humans and animals.

In my book Introduction to High Altitude Entomology, published in 1962, I summa rized the results of eight years' studies, mainly on the Himalaya. I have since then had the opportunity of studying the collections of high altitude insects from the Alps, Carpathians, Caucasus, Urals, Alai-Pamirs, Tien Shan, Altai and other im portant mountains of the world in different museums and institutions in Europe. Through the courtesy and generosity of the Academy of Sciences of the Union of Soviet Socialist Republics, I was also able to personally collect insects and make valuable field observations on the Caucasus, the Alai-Pamirs, Ala-Tau and the Tien Shan mountains. Through comparative studies I have tried to synthesize the fundamental principles of high altitude entomology. I have described here the distinctive characters of the high altitude environment, the ecological specializations of the high altitude insects, their ecological inter relations and the outstanding peculiarities of their biogeography. I have also pre sented here an outline of the high altitude entomology of the principal mountains of the world, with brief accounts of their orogeny, geology and vegetation. This book differs from all other contributions in the field in its comparative ecological approach and in the fact that the main emphasis is throughout on the evolution of the high altitude ecosystem as an integral part of the orogeny. High mountains are, in all parts of the world, important and independent centres of origin and differ entiation of distinctive and highly specialized ecosystems and faunas.

The original stimulus which started KENNETH SPENCER on a study of the Agro myzid flies was an invitation, which he accepted, to translate from the German the monograph on Leaf Miners by Professor E. M. HERING. From this developed nearly 20 years of collaboration until Professor HERING's death in 1967. Dr. SPENCER has himself described over 600 new species in the family, many of which he collected and reared from known host plants during his extensive travels to all the five main continents. Largely as a result of his work, the number of species known in Britain has increased from 90 in 1945 to 313 today. He is thus uniquely qualified to write this book about the hundred and fifty or so species which are regularly associated with cultivated plants. Much of the taxonomic detail provided here will be of value primarily to specialists; but with the help of a microscope and the botanical host list (Chapter 2) and the numerous illustrations (mostly prepared by ANN SPENCER) those in agri cultural institutes and elsewhere should now be able to identify the majority of species found attacking crops in any part of the world.

Allen im Vorwort zu Band I und II angefuhrten Damen und Herren danke ich nochmals herzlich und ganz besonders auch wieder der Deutschen Forschungsgemeinschaft fur ihre Hilfe. Ganz besonderen Dank auch wieder meiner lieben Frau, die mir unentwegt zur Seite stand und meinem lieben Freund Dr. Alfred KALTENBACH, der mir die Bearbeitung der Mantodea abnahm und sie vorzuglich durchfuhrte, und meinem verehrten Freund, Prof. Dr. Erwin SCHIMITSCHEK, Wien fur seine Hilfe, sowie meinen lieben Freunden Patricia HOLMES, Bir- mingham, und Michael SAMWAYS, London, fur die Durchsicht der englisc4en Manuskri ptteile. Weil sich die Gelegenheit bot in einer Sammlung Neotypen fur verschollene Typen einzusetzen, habe ich dies getan; naturlich nicht um des Neotypus willen, sondern um einwandfreies Vergleichs- material sicherzustellen, denn es hat sich doch wiederholt ergeben, dass seither als einwandfrei betrachtete Arten mit fortschreitender Untersuchungstechnik und Verhaltensstudien sich plotzlich in einige Arten aufspalten liessen.Selbstverstandlich habe ich mich zuvor in Rundschreiben an viele Kollegen in Europa nach dem Typenverbleib erkundigt und dann Neotypen von einem dem locus typicus moglichst nah liegendem Fundort eingesetzt. Wenn diese Neotypen nicht im- mer "Ausnahmefalle" im Interesse der Stabilitat der Nomenklatur waren, wie sie die "International Commission on Zoological Nomen- dature" vorschreibt, so geschah dies aus dem angefuhrten Grund; eines Tages mogen sie sich doch als nutzlich erweisen.

As editor of this volume I am not going to emphasize the economic im portance of the Bruchids of pulses, nor how necessary it is to know the conditions of infestation of crops in order to achieve an efficient protection; both points are testified by F.A.O.'s sponsorship, as well as of the International Organization for Biological Control. On the other hand I would like to stress the scientific interest of the study of 'domestic' bruchids. It raises questions which require that present basic entomological knowledge be extended. I am not going to review all questions raised but I will emphasize those I am most aware of. Some bruchid species have been able to colonize habitats differing totally; some differing in their latitude, and thus their basic periodicities; others differing in their degree of complexity (stocks of seeds): What are the respective roles played by polymorphism and plasticity in that exceptional capacity? What differences are there between the populations living on wild plants in dispersal areas and those living in stocks? What are the alterations brought about by the drastic selection pressures in populations having later colonized habitats ecologically similar to the original habitats? What factors determine the degree of specificity of trophic relationships, and the possibilities of extension of the niche? What influences are exerted by the other elements of the original bio cenoses upon the behavioural evolution of these species? Such are a few fundamental problems that can be tackled directly through
