Book Description
Peritrophic membranes are secretion products of the midgut. For long they have been related only to insects, but they occur widely in the animal kingdom. They effect a part of the gut lumen and function not only as a mechanical protection barrier, but also as an ultrafilter, a barrier to parasites, and as envelopes for fecal pellets. Such peritrophic envelopes are of great ecological importance in marine environments. The book is divided into the following themes: - Occurrence - Formation and Structure - Degradation - Chemical Composition - Functions. It is the first comprehensive compilation of all data concerning peritrophic membranes and will provide a basis for future researches in this up to now often neglected field.

Book Description
Entomological research benefits from a great diversity of technical approaches - from the molecular to the descriptive - and these are applied to an even greater diversity of insect species. As a consequence, common themes and trends in entomological research can often be overlooked as each researcher focuses on his or her own area of interest. The purpose of this volume is to bring together diverse areas of research under one common theme. The book is divisible into four conceptual areas: the structural biology of the midgut; digestion and transport; the insect midgut as a target for control strategies; and the idgut as an environment for other organisms. Each chapter is written by scientists active in the reviewed research area and a truly international team of contributors has been chosen by the editors. Biology of the Insect Midgut will be of immense use to advanced undergraduate and postgraduate students, and researchers in entomology, physiology and pest control.

Book Description
Emphasis is placed on the elaborate cuticular matrices in insects and crustaceans, spider and insect silks, sialomes of phytophagous and blood-feeding arthropods as well as on secretions of male and female accessory glands. Focus is placed largely on insects, due to the extensive body of published research that in part is the result of available whole genome sequences of several model species (in particular Drosophila melanogaster) and accessible ESTs for other species. Such advances have facilitated fundamental insights into genomic, proteomic and molecular biology-based physiology. This new volume contains comprehensive contributions on extracellular composite matrices in arthropods. The building blocks of such matrices are formed in and secreted by single layered epithelial cells into exterior domains where their final assembly takes place.Additionally, the unique mechanical properties of natural biocomposites like chitin/chitosan, the crustacean mineralized exoskeleton, the pliant protein resilin or insect and spider silks, have inspired basic and applied research that yield sophistical biomimetics and structural biocomposite hybrids important for future industrial and biomedical use. In summary, this book provides an invaluable vast source of basic and applied information for a plethora of scientists as well as textbook for graduate and advanced undergraduate students.

Book Description
Physiology of the Cladocera, Second Edition, is a much-needed summary of foundational information on these increasingly important model organisms. This unique and valuable review is based on the world’s literature, including Russian research not previously widely available, and offers systematically arranged data on the physiology of Cladocera, assisting with explanation of their life and distribution. It features the addition of new sections and a vast amount of new information, such as the latest data on feeding, nutrition, pathological physiology, chemical composition, neurosecretion, and behavior, as well as hormonal regulation, antioxidants, and the biochemical background of effects of natural and anthropogenic factors. Additional expertly updated contributions in genetics and cytology, and a new chapter in embryology, round out the physiological chapters, and provide comprehensive insight into the state of knowledge of Cladocera and their underlying mechanisms. Cladocera crustaceans have become globally studied for many purposes, including genetic, molecular, ecological, environmental, water quality, systematics, and evolutionary biology research. Since the genome of Daphnia was sequenced and published, that system has gained much wider exposure, also leading to a rapidly growing awareness of the importance of understanding physiological processes as they relate to evolutionary and ecological genomics as well as ecogenomic toxicology. However, the physiological background on Cladocera has been fragmentary (including on the other 700 known species besides Daphnia), despite the extensive literature on species identification and morphology. This work addresses this issue by collecting and synthesizing from the literature the state of knowledge of cladoceran physiology, including discussion on both adequately and inadequately investigated fields, and thus directions of future research. Summarizes fundamental information obtained in recent years, including on steroids, antioxidants, hormones, nanoparticles, and impact of wastewater of pharmaceutical industries Provides the foundational information needed for scientists and practitioners from a variety of fields, including conservation and evolutionary biology, genomics, ecology, ecotoxicology, comparative physiology, limnology, zoology–carcinology, and water quality assessment Features coverage of both Daphniids and representatives of other families, with attention drawn to little-studied aspects of their physiology, especially of those living in the litt oral zone Includes guidance to the literature on cladoceran physiology in four languages Discusses advantages and shortcomings of Cladocera as experimental animals and indicators of water quality

Book Description
The opportunity to explore a developing new technology in a single biological system, chitin, from the molecular basis and with the inter relationship of the utilization of benzoylphenyl ureas in effective pest agroecosystem management strategies, represents a new evolution for integration of knowledge in this highly complex area. The degree of great progress and interest in the understanding of the interaction of chitin uItrastructures, biochemistry, and the unique ben zoylphenyl ureas attest to the timeliness of this effort. The purpose of the book that follows is to provide up-to-date and well illustrated details of current research knowledge including the latest of research results. The combination of the basic to the applied aspects rarely occurs specifically at the levels presented by the international contributors within. The original contributions composed the symposium "Chitin and Ben zoylphenyl Urea" organized by the co-editors at the International Con gress of Entomology in Hamberg, Germany, August 1984. We extend our appreciation to everyone who made the conference an outstanding success and highlight of the Congress, as well as making this book possible. We thank the authors, especially for their excellent international presenta tions, discussions, and preparation of the manuscripts. The knowledge evolved from many areas in chitin research, as well as the intricate com plexity of successful utilization of specific knowledge involving benzoylp henyl ureas in system management strategies for insects will continue to be in the forefront throughout the world's agroecosystems; and hopefully this book will enhance further research and development.
