Book Description
The new series "Microbiology Monographs" begins with two volumes on intracellular components in prokaryotes. In this first volume, "Inclusions in Prokaryotes", the components, labeled inclusions, are defined as discrete bodies resulting from synthesis of a metabolic product. Research on the biosynthesis and reutilization of the accumulated materials is still in progress, and interest in the inclusions is growing. This comprehensive volume provides historical background and comprehensive reviews of eight well-known prokaryotic inclusions.

Book Description
Nature helps... of course at first itself by developing measures that give bacteria, fungi, plants and animals a chance to be successful in their struggle for life. As a latecomer on Earth, Homo sapiens was gifted with some droplets of the divine spirit of recognition and thus became able to observe, to analyse and recombine skills of other living beings and to use them for his overwhelming career over the last 10,000 years. Of course fungi, plants, animals and even bacteria were primarily used by mankind as food or as lifestyle products such as beer, but soon it became clear that there was much more potential hidden in these organisms and that they could be used for other purposes, too. Extracts of plants and fungi were recognized as powerful remedies, as medicines, as insecticides or acarizides, as repellents against parasites or even as weapons, e.g. when poisonous compounds from frogs or plants were applied to arrowheads. Over the last 110 years the pharmaceutical industry has often simulated nature by analyzing complex organic substances taken from living organisms and then producing by synthesis absolutely pure compounds, which mostly consisted of only one single active substance. These products had the advantage of acting against precisely one target and thus produced fewer possible side effects than the complex plant extracts. However, the more serious side effect was that disease agents could develop resistances to pure medicinal products much more easily. Thus after 70 years of excellent prospects for chemotherapy, some dark clouds appeared and quickly gathered, so that several therapeutic remedies now no longer work. Therefore in many countries - especially in those where the pure chemotherapeutics are too expensive for the poor population - the cry “back to nature” is becoming louder and louder. This has led to an enormous increase of studies that again use natural extracts as remedies in the fight against diseases. The present book summarizes examples of promising aspects in a broad spectrum of applications and shows how extracts derived from bacteria, marine organisms, plants or even animals may help to treat infectious diseases, how such organisms may keep away parasites and pests from the bodies of plants or animals, including humans, and how they can be used directly to aid in diagnosis, promote wound healing and even to help catch criminals. These 15 chapters offer not only basic research on these different fields, but also show how useful and effective products can be developed from research.

Book Description
With the ever-increasing resistance of pests to pesticides and the growing concern over environmental pollution, it becomes evident that the problem of pest attack on crops cannot be solved by any one system. Separate controls need to be integrated into a complex measure, of which biological control would be one component. A rapidly growing factor in biological control is the harnessing of pathogens, showing particular progress have been selected from the major taxonomic divisions, as subjects for a series of compact chapters about their identification, practical use and toxins. Other chapters investigate the potential of genetic engineering; aspects of technology and integration such as formulation, application machinery, ecology and biostatistical modelling; safety and the insects' defence mechanisms; and impressions of use and research in the People's Republic of China. Each of the sixty authors and co-authors is a specialist, writing closely around his own field. Microbial Control of Insects and Mites the 1971 forbear of this book, assessed the subject up to 1970. As a broadly-based reference work, it revealed almost as many problems as solutions, and left inevitable gaps in coverage. This new work is a sequel and a supplement to the now critically-acclaimed initial work and not a revision or new edition: repetition of that material is stringently avoided. The present work covers new material appearing since 1970 and fills some of the gaps. In particular, the scope has been widened to include the use of competitors, inhibitors and diseases of plant pathogens as alternatives to chemical fungicides and bactericides. Although essentially a practical book, it delves deeply into fundamental information when an understanding of the subject is necessary to the reader. Each chapter attempts to probe the future, while the final chapter provides an analysis of the decade's strategy and progress. A painstaking conciseness exercised by contributors and editors has enabled this vast subject to be encompassed in a single volume. The work is aimed at a wide readership of pest control practitioners, research workers, students and lecturers seeking new information on advanced topics. It will interest insect pathologists, entomologists, plant pathologists, ecologists, biochemists and virologists as well as microbiologists generally. Those who have benefitted from its forbear will find this an essential complement to that work.

Book Description
This volume is a revision of Biological Control by R. van den Bosch and P. S. Messenger, originally published by Intext Publishers. In the revision, I have attempted to keep the original theme, and to update it with current research findings and new chapters or sections on insect pathology, microbial control of weeds and plant pathogens, population dynamics, integrated pest management, and economics. The book was written as an undergraduate text, and not as a complete review of the subject area. Various more comprehen sive volumes have been written to serve as handbooks for the experts. This book is designed to provide a concise overview of the complex and valuable field of biological control and to show the relationships to the developing concepts of integrated pest management. Population regulation of pests by natural enemies is the major theme of the book, but other biological methods of pest control are also discussed. The chapter on population dynamics assumes a precalculus-level knowledge of mathematics. Author names of species are listed only once in the text, but all are listed in the Appendix. Any errors or omissions in this volume are my sole responsibility. A. P. Gutierrez Professor of Entomology Division of Biological Control University of California, Berkeley vii Acknowledgments Very special thanks must be given to my colleagues, Professors C. B. Huffaker and L. E. Caltagirone, for the very thorough review they provided and for the many positive suggestions they gave. Dr.
