Download or read book Prothoracicotropic Hormone Cyclic Nucleotides and Proctolin in Insect Central Nervous System written by Timothy Gilmore Kingan and published by . This book was released on 1980 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prothoracicotropic hormone has been partially purified from whole heads of tobacco hornworm larvae, Manduca sexta. Activity was followed with a larval bioassay. Activity was purified 4400 fold from crude extracts. The hormone was found to be a heat-stable polypeptide with an approximate molecular weight of 25,000 Daltons. The hormone has an isoelectric point in the range pH 5.25-5.50. The most purified preparations were shown to possess activity in vitro with a prothoracic gland culture system. Cyclic AMP and cyclic GMP were quantitated in the central nervous system of Manduca sexta during the pre-metamorphic endocrine activity that leads to a change from feeding to wandering behavior and to the commitment to pupal development. Cyclic AMP and cyclic GMP accumulated in the brain in tandem during this period. Cyclic nucleotide levels remained unchanged in abdominal and thoracic ganglia and in the subesophageal ganglion. Proctolin was quantitated by radioimmunoassay in the central nervous system of the Maderae cockroach, Leucophaea maderae. Proctolin RIA activity was found throughout the CNS, with the sixth abdominal and thoracic ganglia being the richest sources. RIA activity was also found in the cockroach hindgut.

Download or read book Recent Developments in Insect Neurohormones written by M. Raabe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most striking fact revealed by investigations of insect neurohormones is that insects are as well supplied with neurohormones as mammals, since neurohor mones regulate not only the functioning of the endocrine glands, prothoracic gland, and corpora allata, but also most physiological processes. Our knowledge of neurohormones developed originally from anat omocytological investigations and experimental studies. Today, accurate bio assays have been devised for studying both in vivo and in vitro physiological processes, and RIA determination has yielded knowledge of titer modifications of humoral factors. Much is also known about neurohormone purification, and several neurohormones have even been identified in different species. Immunocytochemistry has made it possible to demonstrate in their origin and release sites the presence of insect neurohormones whose structure has been elucidated. Moreover, the presence of vertebrate and invertebrate neuropeptides has been demonstrated in insects. As regards biogenic amines, methods of detection have been greatly refined and it is now possible to identify the cell bodies and axons of the main biogenic amines. Other new methods, such as cobalt chloride impregnation or Lucifer yellow staining, have revealed the axonal pathways and the location of particular neurons. The mechanisms of action of neurohormones have been investigated in several cases and the results of these investigations will be related in the chapters which follow.

Download or read book Endocrinology II written by G. A. Kerkut and published by Elsevier. This book was released on 2013-10-22 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocrinology II concerns the actions of hormones in insects, complementing Volume 7 which is concerned with the production and chemistry of insect hormones. While the preceding volume is directed mainly towards the insect endocrinologist, this volume has much of intrinsic interest to the general physiologist. It deals with the regulation of metabolism, reproduction, cuticle properties, and certain aspects of behaviour from a systems point of view and amply documents how hormones have provided basic insights into the functioning of such systems. Interference in endocrine regulation could provide future systems for insect control and this volume will provide the foundation on which the future formulation of these strategies is based. More information on diverse aspects of insect hormone action is brought together here than in any previous single work and this volume will therefore be a valuable reference source for many years to come.

Book excerpt: Advances in Insect Physiology, Volume 59, examines the molecular and developmental origins of insect extended phenotypes, their diverse physiological functions, their consequences for the ecology and evolution of insects, and their biotic partners. Chapters cover recent ideas about the significance and roles of extended phenotypes and provide overviews of the latest advances. Written for a broad audience of researchers and students, the book's chapters establish extended phenotypes as focal structures for understanding genotype-to-phenotype maps, the origins and consequences of complex traits among multiple interacting partners, and the roles they may play in providing resilience against climate change. Compiles and synthesizes the latest advances in understanding extended phenotypes Provides detailed information on molecular and cellular mechanisms underpinning formation and control of extended phenotypes Gives comprehensive implications of extended phenotypes for ecology, evolution and applied systems
Download or read book Neuropeptide Systems as Targets for Parasite and Pest Control written by Timothy G. Geary and published by Springer Science & Business Media. This book was released on 2011-01-13 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to continually discover new agents for the control or treatment of invertebrate pests and pathogens is undeniable. Agriculture, both animal and plant, succeeds only to the extent that arthropod and helminth consumers, vectors and pathogens can be kept at bay. Humans and their companion animals are also plagued by invertebrate parasites. The deployment of chemical agents for these purposes inevitably elicits the selection of resistant populations of the targets of control, necessitating a regular introduction of new kinds of molecules. Experience in other areas of chemotherapy has shown that a thorough understanding of the biology of disease is an essential platform upon which to build a discovery program. Unfortunately, investment of research resources into understanding the basic physiology of invertebrates as a strategy to illuminate new molecular targets for pesticide and parasiticide discovery has been scarce, and the pace of introduction of new molecules for these indications has been slowed as a result. An exciting and so far unexploited area to explore in this regard is invertebrate neuropeptide physiology. This book was assembled to focus attention on this promising field by compiling a comprehensive review of recent research on neuropeptides in arthropods and helminths, with contributions from many of the leading laboratories working on these systems.
