Book Description
The connection between the study of insects. their development. behaviour and biochemistry. and chromatography is perhaps not immediately obvious. However. this connection exists and it is of fundamental importance to our understanding of many areas of insect physiology. Insects range in size from small to minute and consequently the amounts of hormones or pheromones they produce are equally minute. Ultimately any attempt at understanding the processes which control development, social behaviour or the biochemistry of insects requires some means of isolating the tiny quantities of the hormones and pheromones responsible in sufficient quantity and purity for identification. The ability to devise novel techniques to separate these materials from frequently complex biological mixtures including precursors and metabolites and to devise detection systems for them is vital. Methods for the quantification of these substances at different stages in the life cycle. or in response to environmental change or stress. are then essential. Chromatography. both as a means for isolation and as a method for quantitative analysis. has "been an essential tool in these studies. This volume represents the outcome of a joint international symposium organized by the Chromatographic and Royal Entomological Societies at the University of Reading between the 21st and 23rd March 1989 aimed specifically at discussing the chromatography and isolation of insect hormones. pheromones and related substances.The papers presented at that meeting. and collected together here. covered many aspects of the subject including the chromatography of juvenile hormones. ecdysteroids. peptides. pheromones and semio chemicals.

Book Description
NEUROTOX '91 was the fourth meeting in a series which started in 1979. The '91 meeting, like its predecessors, was held under the patronage of the Society of Chemical Industry, and despite the unfortunate proximity of hostilities in the Arabian Gulf attracted a truly international mix of industrial and academic pesticide scientists. This volume contains the text of invited papers read at the meeting and presents the dramatic developments which so excited those who attended. The potential of molecular neurobiology for gaining knowledge of target sites for neurotoxicants is now starting to be realised. These studies, in conjunction with developments in molecular imaging and modelling, provide new oppor tunities for chemists and biologists to gain insights into molecular interactions underlying intoxication. Molecular techniques have also enabled rapid ad vances on a second front, where the cloning of genes controlling pesticide resistance should have a profound impact on our understanding of this commercially important problem. The understanding of molecular events will undoubtedly be vital in future developments in chemical control of pests; however, the value of understand ing the way in which the nervous system controls behaviour and how behaviour can be modified by chemicals of bath synthetic and natural origins was highlighted. Natural products and their synthetic analogues have continued to provide new and interesting molecules which are already proving their worth as tools for the neuroscientist and may offer leads for commercial synthesis.

Book Description
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 programs. 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 worldwide 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 pest-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.

Book Description
This book contains the proceedings of the "First International Symposium on Insect Pheromones," which was held at Wageningen, The Netherlands, from March 6 to March 11, 1994. Eighty participants from 17 countries attended the symposium, which turned out to be a unique forum for the exchange of the latest worldwide findings on insect pheromones, an opportunity to discuss and debate unsettled issues, and a mechanism to define new directions in pheromone research and foster interdisciplinary collaborations. The meeting comprised five sessions representing the breadth of disciplinary interest in pheromones, a typical charac teristic of this research area. In the sessions the following topics were presented: (1) control of pheromone production (organized by W. L. Roelofs), (2) sensory processing of pheromone signals (T. L. Payne), (3) neuroethology of pheromone mediated responses (T. C. Baker), (4) use of pheromones in direct control (A. K. Minks and R. T. Card6), and (5) evolution of pheromone communication (c. LOfstedt). All sessions started with a series of 30-minute lectures, after which ample time was reserved for discussion. In each session some participants were asked to serve as discussants and to initiate and stimulate discussion, and a rapporteur was recruited to make notes of these discussions and to summarize the general trends emerging from the session. The general program ming of the symposium was in the hands of R. T. Carde, A. K. Minks, and T. L. Payne.

Book Description
Advances in Invertebrate (Neuro)Endocrinology: A Collection of Reviews in the Post-Genomic Era (2-volume set) provides an informative series of reviews from expert scientists who are at the forefront of their research into the endocrinology of invertebrates. These two volumes are timely and appropriate in this post-genomic era because of the rapid pace of change brought about by genome projects, functional genomics, and genetics (omics technologies). The volume shows the rich history and strong tradition of cutting-edge research using invertebrates that has opened up our broader understanding of comparative endocrinology and the evolution of regulatory pathways and systems. These reviews set the scene and context for this exciting new era of understanding that has come from this post-genomic revolution. This book undertakes the daunting task of covering most of the diverse endocrine systems that exist among invertebrates. The papers in this book will advance our knowledge of invertebrate endocrinology but also of endocrinology in general, making the book will be valuable to researchers and students.
