The function of the central nervous system as a coordinator and regulator of cellular processes in multicellular organisms is unequivocal. Until recently, however, the chemical evidence necessary for validating speculations on neurophysiological function in inverte brates has been lacking. In insects, because of their small size, heroic efforts were needed to collect the millions of tissues or organs necessary for isolation and identification of neurochemicals. With the spec tacular advances in physical and analytical technology within the last decade and with significant advances in radiochemical, radioimmunological and neurophysiological assays, researchers are, for the first time, able to handle microgram and nanogram quantities of complex biological substances. More recent developments in immunology promise to lower these levels further. It is not surprising that these new opportunities accelerated progress in insect neuroscience and that the time was right for a rapid and personal exchange of ideas and information on techniques. These considerations were the primary impetus for convening the International Conference on Insect Neurochemistry and Neurophysiology (ICINN) at the University of Maryland, College Park, MD, on August 1-3, 1983."

Borkovec and Masler's timely new volume-Insect Neurochemistry and Neurophysiology * 1989-provides a wide-ranging survey of forefront research in every key area of insect neuroscience by contributors who are internationally renowned authorities in their fields.Divided into three main sections- Neuroanatomy, Neurochemistry, and Neurophysiology, this vanguard collection of original research papers and reviews presented here cover a broad spectrum of topics, including: * neuropeptides * neurodevelopment * neuroendocrinology * blood-brain barrier * eclosion hormone gene * neuroparsins * hypertrehalosemic hormone * oostatic hormone * sex pheromone biosynthesis * corpora allata activity * ecdysiotropins * protein kinase C * ecdysteroid production * precocene II * hypolipemic hormone * neuroanatomy * serotonergic modulation * neurosecretory cells * octopaminergic modulation* tyramine-b-hydroxylase * metabolism of inositol phosphates * genetically engineered baculovirus pesticides * juvenile hormone production * endocrinology of embyrogenesis * molt inhibition by azadirachtin * prothoracicotropic hormone * metabolic changes in nerve tissue * regulation of vitellogenesis * uptake and binding of ponasterone A * gene expression during pupal-adult neurogenesis * chemical regulators of female reproductive muscle function * proctolin and female reproductive tissue immunochemistry.Insect Neurochemistry and Neurophysiology * 1989 is an indispensable resource and reference for all workers in the neurosciences, entomology, pesticide research, and related areas.

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."
