In this volume, seven of the chapters deal with feeding and diet, which is reasonable since insects consume an estimated l5-20% of all the world's planted crops. Many insects even have a specialized larval feeding stage that usually occupies a different ecological niche to the adult and so does not compete for the adult's food stock. Other chapters describe the means by which insects maintain their water balance, nitrogen balance and temperature balance under a range of conditions. These involve regulation by hormonal and behavioural systems that are also described here. The l4 chapters are all extensively illustrated and referenced and therefore provide excellent summaries of current knowledge. They will be of great value to entomologists, zoologists and biologists in general.

The digestive and the excretory systems take the food we eat through a marvelous maze. Every bite travels from the mouth to the stomach to the intestines. Food is separated into nutrients and waste products, which both systems expel. Along the way, the digestive system mashes, chops, crushes, dissolves, and breaks down the food into molecules of nutrients. These provide energy to the rest of the body. The excretory system filters the blood and regulates the amount of salt and water in the body. Learn how these remarkable systems work together to bring us life-giving nutrients and rid our bodies of waste. Book jacket.

TO ACCESS THE ARTWORK FROM THE BOOK, PLEASE VISITwww.blackwellpublishing.com/gullan. This established and popular textbook is the definitive guide tothe study of insects; a group of animals that represent over halfof the planet’s biological diversity. Completely updated and expanded, this new edition examines allaspects of insect biology including anatomy and physiology, ecologyand evolution of insects, insect behaviours such as sociality,predation, parasitism and defense, medical and veterinaryentomology and methods of collection, preserving and identifyinginsects. Features new chapters on the methods and results of studies ofinsect phylogeny and a new review of insect evolution andbiogeography. Includes expanded sections on species diversity, socialbehaviour, pest management, aquatic entomology, parasitology andmedical entomology. Successful strategies in insect conservation are also coveredfor the first time, reflecting the increasing threat to naturalecosystems from environmental changes. Boxes highlighting key themes, suggestions for further readingand illustrations, including specially commissioned drawings andcolour plates, are included throughout.

Volume 20 of this series deals with a variety of plant and animal ecology topics.**Despite much recent work on herbivory, little attention has been given to insect herbivores active below ground. Brown and Gange describe the ecological adaptations of insects to this abundant but poor quality food resource, and the responses of plants to this potentially very damaging grazing pressure.**Plants living at high altitude must be able to cope with extreme climatic conditions, low carbon dioxide levels, and high radiation doses. Friend and Woodward describe these adaptations and discuss the degree to which they are genetically determined or merely the product of physiological plasticity.**Thomas presents a modular concept of ecology in which modules contain a resource and its associated consumers, and goes on to examine the general principles which may reflect the various mutualisms between organisms in some example fresh water modular systems.**Finally, West examines the microphytic soil crusts of arid and semi-arid soils. Although information on them is currently limited, they are likely to be important in some ecosystems.

This volume is primarily devoted to the analysis of the integument (epidermis, cuticle), the fat body, the connective tissues, the circulatory and respiratory systems. It discusses the organization and functioning of the insect systems implicated in growth, intermediary metabolism, homeostasis and defence mechanisms. Much of the volume is devoted to anatomical and structural developments, which appear as introductions to corresponding biochemical and physiological aspects. Many diagrams, drawings and photographs accompany the text throughout. Altogether, this volume presents a clear and up-to-date account of the most recent and important discoveries in the fields and shows the extent of progress which is expected in the near future.

Over the past 25 years insect pharmacology has grown from a fledgling subject to one that occupies a major field of science. Volume ll reviews insect pharmacology past and present and effectively captures the growing confidence which imbues the world of the insect pharmacologist. It contains l5 chapters written in authoritative fashion by leading scientists and is fully illustrated and referenced. Insect preparations are proving ideal for resolving problems in pharmacology which have general significance, particularly at the molecular and genetic levels. This volume contains a wealth of data, information and ideas and will therefore be a valuable asset to all in academic or industrial research concerned with the science and control of insects.

Volume 12 is devoted to current and future approaches to insect management and control. The topics discussed cover chemical control, including the use of juvenile hormone analogs, microbiological methods, including viral and fungal agents, biological control, and genetic approaches to insect control. The 20 chapters, all amply referenced and illustrated, well demonstrate the multidisciplinary nature of the subject and the degree of international effort that has led to the present state of knowledge. Fifteen of the chapters are devoted to the action of insecticides, reflecting the immensity of the subject. The past 30 years have witnessed remarkable advances in the scientific basis of insect control and this volume provides a convenient point of entry into the massive amount of literature now available.

The underlying theme of this volume is the understanding of the molecules and processes important in the primary metabolism of insects. The 19 chapters provide both rich historical perspectives and timely reviews of current research, as well as showing the extent of progress to be expected in the near future, including the application of advanced techniques now used for the study of microbial and mammalian processes. The major themes of metabolism, proteins and nucleic acids, and biochemical events in the nervous system each have several chapters devoted to them, but specific topics such as pigments, toxins, and aging are also covered in detail. This extensive volume is therefore an invaluable source of information not only for entomologists but also for all scientists whose work involves insect biochemistry, including zoologists, biochemists, and molecular biologists and geneticists.
