Book Description
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 carefully prepared chapters by international experts, covering the full breadth of the subject in order to give an up-to-date 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 provides a staging point for further enquiries. The volume will be of interest to a wide variety of entomologists and other biologists interested in the control and evolution of life cycles and in understanding the extraordinarily complex ecological strategies of insects and other organisms.

Book Description
This book was developed out of a symposium at the XVII International Congress of Entomology held in Hamburg, Germany, on August 21, 1984. This symposium was organized by Drs. William Bradshaw and Hugh Dingle, who subsequently asked us to edit the proceedings. The chapters represent, for the most part, papers that were read in Hamburg but have been expanded and updated. The goal of this volume is to provide a comprehensive view of current research on insect life cycles, including field and laboratory studies, broad comparisons among species or local populations, and intensive studies of single populations, as well as theoretical research. Of necessity, given the magnitude of research now being carried out on insects, some important research programs are not included, and therein lie the makings of future volumes. This volume is divided into three parts. The first part, Geographical Patterns in Insect Life Cycles, explores various applications of a comparative method that has been valuable in investigating the potential for variability in life history parameters and the relation of these parameters to important variables in the environment.

Book Description
No International Congress of Entomology would now be complete without a symposium on insect life-cycles. The latest Congress, held at Vancouver, BC (Canada), in July 1988, was no exception, with a symposium on the genetics, evolution, and coordination of insect life cycles organized by Bill Bradshaw and Valerie Brown. The present volume arose from papers contributed by most of the speakers at the symposium, together with papers from other invited authors. In editing the book, I have been assisted greatly by the other authors, particularly Bill Bradshaw, Val Brown and Fritz Taylor. All contributors agreed to referee two other chapters, a system that worked efficiently and effectively: I thank all authors for performing this task in the face of other demands on their time. I would also like to thank Philip Corbet, John Greenslade, Bryan Clarke, and Gillian Thompson of Springer for their help.

Book Description
This volume results from a symposium entitled "Species and Ufe History Patterns: Geographic and Habitat Variation", held during the National Meeting of the Entomo logical Society of America in Denver, Colorado, USA in November, 1979. The stimu lus to assemble papers on this theme emerged from continuing discussions with col leagues concerning controversies in ecology and evolutionary biology, namely those associated with plant-herbivore interactions, life history theory, and the equilibrium status of communities. The study organisms used in this series of reports are all either herbivorous insects or those intimately associated with plants. In this volume we stress the variation found in life history traits and address some of the problems inherent in current life history theory. We include as life history traits not only traditional variables such as fecundity, size of young, and age to first and peak reproduction, but also diapause and migration, traits that synchronize reproduction with favorable plant resources. Because life history traits of phytophagous insects are influenced in part by spatial and temporal variation in the quality and availability of their host plants, we also consider the role that dis continuities in plant quality play in reducing insect fitness. Lastly, much of the tra ditional life history theory concerns itself with differences between the evolution of traits or constellations of traits when populations incur primarily density-independent, compared to density-dependent, mortality. Consequently, we address this issue and attempt to shed light on the equilibrium status of several phytophagous insect com munities.

Book Description
This textbook contains important, comprehensive and in-depth account of all aspects of insect physiology, providing wherever necessary also the fundamental knowledge of the various systems. Although it is aimed as a resource material for postgraduate students of entomology, it would serve as an essential reference source for invertebrate physiologists and neurologists, entomologists, zoologists and insect biochemists. To achieve this goal, extensive references have been made to several textbooks and reviews, to a few research papers dealing with applied aspects of insect physiology and the resources available over the net. The first chapter deals with the anatomical and physiological attributes of the integument conferring insect success with a discussion on the use of the chemical properties of the cuticle to design novel molecules to control insect pests. The chapter also indicates that the structural design of the cuticle could itself be applied in the field of material science to develop hard structures which can withstand the harshness of the environment. Chapter two discusses the diversity in growth and life cycle patterns in insects. Chapters three and six deals with the digestive and excretory systems as potential targets for pest management. Aspects of the circulatory system of insects are presented along with an account on the new frontiers in insect immunity in chapter four. This would appraise the reader on the possible improved use of entomopathogens in biological control, in the discovery of antimicrobial molecules that can be exploited by humans, and of new strategies for management of insect vectors of human and animal disease. While the dynamism of the respiratory system (Chapter five) is presented as a key to their success, the use of the knowledge thus gained in fluid dynamics and biomechanical research is mentioned. An up to date account on the insect nervous system is presented in Chapter seven, together with a note on learning, memory and intelligence in insects. Chapter eight deals with the reproductive system of insects while chapter nine deals with hormones and regulation of metabolism, moulting and diapause. General protein, carbohydrate and lipid metabolism and their energetic are presented in chapter ten along with the physiology of regulation in cold hardiness and flight. Chapter eleven deals with muscular coordination while an in depth account on the sensory physiology and behaviour is presented in chapter twelve.

Book Description
Research on Chrysomelidae vol. 3 continues a series which began under Brill Academic Publishers, Leiden, with volume 1 in 2008. Volume 2 appeared in 2009 and had four regularly submitted papers and the Proceedings of the 7th International Symposium on the Chrysomelidae (held 6-8 July, 2008 at Durban, South Africa) with nine papers based on presentations to this meeting. The present volume also combines a number of regular papers with the proceedings of a symposium. In 2010, the European Symposium on the Biology of the Chrysomelidae was held within the frame of the IXth European Congress of Entomology (ECE) at Budapest, Hungary, on August 23. Hungary ? as the host country of the congress - has a long tradition of entomological research and always had a marked bridging role in the social life of entomologists of Europe. The ECE has been co-organized by the Hungarian Entomological Society which celebrated its 100th anniversary in 2010. The Hungarian Entomological Society is one of the oldest scientific societies in Hungary with continuous activity, including the 1950s, when most Hungarian societies were dissolved by the communist government. This congress offered an important opportunity for entomologist to exchange ideas, results, and social matters. On top of all, the city of Budapest provided a beautiful background to this memorable scientific and social event. We, the organisers of the Symposium on Chrysomelidae, are proud and happy to see our conference represented by five papers based on contributions to it in vol. 157 of ZooKeys (Research on Chrysomelidae vol. 3). Four more papers on leaf beetles complete this volume. We thank authors and publishers for helping to make research on leaf beetles more visible and easier to access.

Book Description
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 2 is a the second volume of a series of volumes on the Chrysomelidae edited by Jolivet, Santiago-Blay, and Schmitt.

Book Description
Insects provide excellent model systems for understanding evolutionary ecology. They are abundant, small, and relatively easy to rear, and these traits facilitate both field and laboratory experiments. This book has been developed from the Royal Entomological Society's 22nd international symposium, held in Reading in 2003. Topics include speciation and adaptation; life history, phenotype plasticity and genetics; sexual selection and reproductive biology; insect-plant interactions; insect-natural enemy interactions; and social insects.
