Chromatography and Isolation of Insect Hormones and Pheromones


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.







Neurobiology of Chemical Communication


Book Description

Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.




Advances in Invertebrate (Neuro)Endocrinology


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.




Handbook of Major Palm Pests


Book Description

Handbook of Major Palm Pests: Biology and Management contains the most comprehensive and up-to-date information on the red palm weevil and the palm borer moth, two newly emergent invasive palm pests which are adversely affecting palm trees around the world. It provides state-of-the-art scientific information on the ecology, biology, and management of palm pests from a global group of experts in the field. An essential compendium for anyone working with or studying palms, it is dedicated to the detection, eradication, and containment of these invasive species, which threaten the health and very existence of global palm crops.




Insect Reproduction


Book Description

This book consisting of ten review chapters contributed by leading workers in their respective fields, from around the world, covers the whole subject of insect reproduction.It begins with the basic physiological questions of insect reproduction, moves on to discuss the new advances seen in the fields of behavioural and ecological mechanisms, and culminates by examining the recent work on evolutionary biology and its application in the field. Each chapter, although including a brief review of the basic seminal work, focuses mainly on the advances made within the last ten years and highlights those areas in which the respective authors see the greatest scope for further important advances




International Review of Cytology


Book Description

International Review of Cytology presents current advances and comprehensive reviews in cell biology--both plant and animal. Articles in this volume address such topics as cytoskeleton-dependent transport and localization of nRNA, special cytochemistry in cell biology, plasticity and stabilization of neuromuscular and CNS synapses, adipokinetic hormones of insects, and iron metabolism in mammalian cells. Authored by some of the foremost scientists in the field, each volume provides up-to-date information and directions for future research.




Olfaction in Mosquito-Host Interactions


Book Description

This new work contains the first integrated discussion of the role of olfaction in mosquito-host interactions. It covers the practical applications of this knowledge in attempting to control malaria as a problem for world health. The volume begins with a general overview of mosquito life cycle styles and how odour-mediated host location fits into the repertoire of behaviours that a specific species may exhibit. Certain aspects of insect olfaction and its underlying physiological mechanisms are incorporated within the book.




Insect Repellents
