Neurohormonal Techniques in Insects Excerpt :

Insects as a group occupy a middle ground in the biosphere between bac teria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available in struments are geared to measure in grams, while the forces commonly en countered in studying insects are in the milligram range. Therefore, tech the study of insects or in those fields concerned with niques developed in the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been sufficiently ironed out to permit students to master the manipulations in a few laboratory periods. Many specialized techniques are confined to one specific research labo ratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save con siderable time. It is the purpose of this series (1) to report new develop ments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe ex periments which might be applicable for use in biology laboratory courses.

Recent Developments in Insect Neurohormones 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.

Neurochemical Techniques in Insect Research Excerpt :

Neurochemical Techniques in Insect Research properly emphasizes the insect. It only scratches the surface of the exploding repertoire of general neuro chemical techniques that can be applied to insect research in 1985. But it al so presents the advantages of using insects for studying certain biological questions that are approachable by neurochemical techniques. Even more so, it summarizes the long list of unique problems encountered in attempting to study insects by neurochemical techniques. As in other volumes of this series, the contributors to this volume are the authorities in the field. They themselves have developed much of the material presented. Thus the sum effort provides a true description of the state of the art; and, pleasantly, it does so in a very complete and clear manner. Readers of this series will not need to be reminded that, despite the fact that vertebrates make up only about 3% of all animal species, research in in vertebrates such as insects has lagged behind that on vertebrates, at least in the neurochemistry area; the relative simplicity and large cell size of the in sect nervous system has always provided incentive for work in neurophysiol ogy and neuroanatomy. Toxicology interests will always stimulate a certain amount of work on insect neuropharmacology, and insects are extremely suitable for several areas of toxin research. Last but not least, the insects are beautiful organisms for which the applications of genetics can be made to the study of nervous system function.

Environmental Physiology and Biochemistry of Insects Excerpt :

Of all the zoological classes the insects are the most numerous in species and the most varied in structure. Estimates of the number 18 of species vary from 1 to 10 million, and 10 individuals are es timated to be alive at any given moment. In their evolution, in sects are relatively ancient and, therefore, they have proved to be a phenomenally successful biological design which has survived unchanged in its basic winged form during the last 300 m. y. In sects were the first small animals to colonize the land with full suc cess. Their small size opened many more ecological niches to them and permitted a greater diversification than the vertebrates. What is it about this design that has made insects so successful in habitats stretching from arid deserts to the Arctic and Antarctic and from freshwater brooks to hot springs and salines? Is it due to the adapta bility of their behavior, physiology, and biochemistry to changing environmental conditions? Three features of insects are of particular importance in determin ing their physiological relationship with the environment: their small size, as mentioned above, the impermeability and rigidity of their exoskeleton, and their poikilothermy. Of course, as with any other animals, the insects' success in its environment depends on its ability to maintain its internal state within certain tolerable limits of temperature, osmotic pressure, pH or oxygen concentra tion (homoeostasis).

Insect Neurochemistry and Neurophysiology 1986 Excerpt :

The nature and diversity of presentations at the second International Conference on Insect Neurochemistry and Neurophysiology (ICINN--86) held at the University of Maryland on August 4-6. 1986, attest to the vital ity and broad scope of research in insect neuroscience. The present vol ume is a written account of the invited lectures, contributed papers, and posters presented at the conference, and as such, serves as a fair indica tor of the trends in current research in this field here and abroad. The principal portion of this book consists of seven review papers that were presented by invited speakers. Although the topics vary wide ly, they reflect on and emphasize the main theme of the conference, i. e. , the nature and function of molecular messengers that communicate be meen the central nervous system and organs or tissues involved in the growth, development, reproduction, and behavior of insects. This empha sis is continued in the following three sections on neurochemistry, neuro physiology, and neuroanatomy, although no conscious effort was made by the organizers to highlight these particular fields of neuroscience. It is evident that the recent advances in both physical and chemical analyti cal techniques have made possible the acquisition of structurally defined probes, the long sought-after tools for unraveling the secrets of endogen ous communication. Each section of short papers derived from the oral and poster presentations at the conference is prefaced by an overview that highlights and summarizes the section's content.

Insect Hormones Excerpt :

Although insect endocrinology is one of the oldest and most active branches of insect physiology, its classic general texts are long out of date, while its abundant primary literature provides little biological context in which to make sense of the discipline as a whole. In this book, H. Frederik Nijhout's goal is to provide a complete, concise, and up-to-date source for students and nonspecialists seeking an overview of the dynamic and wide-ranging science that insect endocrinology has become since its beginnings nearly eighty years ago in the study of insect metamorphosis. The author offers a comprehensive survey of the many roles that hormones play in the biology of insects. Among the topics discussed are the control of molting, metamorphosis, reproduction, caste determination in social insects, diapause, migration, carbohydrate and lipid metabolism, diuresis, and behavior. The account features a summary of the most current and accurate thinking on the complex roles of ecdysone and juvenile hormone in the control of metamorphosis, a process still misunderstood and misrepresented in biological textbooks and many professional reviews. Throughout, the book's emphasis is on the biology of the organism and the ways in which physiological and developmental regulatory mechanisms are integrated into the insect's life cycle.

Insect Neurohormones Excerpt :

The discovery of insect neurohormones dates from the earliest experimental in vestigations in insect endocrines, and the matter cannot be discussed without evoking the names of its pioneers-Kopec, Wigglesworth, Fraenkel. Whereas the experiments demonstrated the existence of the first known neurohormones, the formulation of the concept of neurosecretion was of fundamental importance to further progress, and tribute must be paid to Ernst and Berta Scharrer. The recent proliferation of investigations into insect neurohormones has cre ated the need for an overall review of the data. Our knowledge of the subject is voluminous, and the evidence clearly demonstrates that neurohormones playa part in most insect regulatory processes. This book analyzes and synthesizes the data, starting from neurosecretion (i.e., source sites and release modes of neurohormones) and continuing through the various functions in which neurohormones have been shown to be involved: endocrine gland activity; diapause; reproduction; visceral muscle functioning; color change; behavior; water and ion balance; protein, sugar, and lipid metabo lism; and tanning and other processes occurring at the cuticle level. In each chapter, besides the experimental information, technical procedures as well as recent information concerning purification of the particular neurohor mones and their mode of action are reported. Numerous exhaustive tables allow the reader to get an overview of the matter while the major findings of the mo ment are presented in the conclusion of each chapter.
