Available in PDF, EPUB and Kindle. Book excerpt: The scientific program for the XVI International Congress of Entomology, held in Kyoto, Japan August 3-9, 1980 included a symposium on the subject of "Energy Metabolism and Its Regulation in Insects." The symposium provided an opportunity to integrate knowledge, and focus attention, on an important and fundamental aspect of insect biochemis try/physiology. The energy metabolism of insects differs from that of other animals in a variety of ways, including the prodigious amounts of energy expended by flying insects, the presence in hemolymph of large concentrations of sugar in the form of the nonreducing disaccharide tre halose, the transport of fat in the form of diacylglycerol, and the periodic mobilization and deposition of cuticular components during development. These differences, together with hormones, neurohormones, and neu rotransmitters that are specific to (or functionally different in) insects, serve to demonstrate the unique nature of energy metabolism in insects. An obvious corollary from the demonstrated uniqueness of insect energy metabolism is that an understanding of the process may lead to the de velopment of new, specific agents or strategies for the suppression of insect pests. The present volume is an expanded version of the Kyoto symposium.

Download or read book Metabolic Aspects Of Lipid Nutrition In Insects written by T. E. Mittler and published by CRC Press. This book was released on 2019-03-01 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the physiological function of insect essential lipids has long been flawed by major uncertainties. It was discovered long ago that dietary sterol is a necessary nutrient for all insects, which radically sets them apart from the vertebrates in terms of qualitative nutrient requirements. Because of the physiological importance of sterol as a molting hormone precursor in insects and the implications of this for the development of new insecticides, a wealth of investigation into insect sterol metabolism followed, covering both the ways in which insects convert diverse food-plant sterols into the major tissue sterols and how these in turn are metabolized into the ecdysone molting hormones. However, for the classes or essential Lipid nutrients required by vertebrates, research dealing with insects has been scant and, more often than not, rather indeterminate. Many, but by no means all, insects studied appear to require essential fatty acids, though virtually nothing has been found out about the metabolism or essential physiological function of these acids. Excepting vitamin A, needed for insect vision, the various vertebrate fat-soluble vitamins appear to have no significance for insect physiology, and results of the occasional attempts to demonstrate functions for them in growth and development have in most cases been tantalizingly equivocal. In recent years some notable advances were made in tne study or essential fatty acids and fat-soluble vitamins in insects, and work on insect sterol nutrition and metabolism continues with ever-increasing sophistication. The contributors to this book summarize, discuss, and speculate on these issues. Their work is based on papers presented at the 1980 World Congress of Entomology at Kyoto, Japan.
Download or read book Energy Metabolism in Animals and Man written by Sir Kenneth Lyon Blaxter and published by CUP Archive. This book was released on 1989-06-29 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This book discusses the factors which affect the heat produced by animals and man and the ways in which the energy of the organic components of their diets are used to support growth and reproduction. The general thermodynamic principles are considered in addition to the physical principles related to heat loss by radiation, convection, conduction and evaporation of water. Major parts of the book deal with the minimal or basal production of heat, with the heat produced during muscular work and as a result of physiological reactions to the climatic environment. The test is intended for undergraduates and postgraduates who are studying energy metabolism in the context of zoology, agriculture, ecology, or medicine.

Download or read book Effect of Juvenile Hormone on Energy Metabolism in the Burying Beetle Nicrophorus Orbicollis written by Joel Hachiya and published by . This book was released on 2015 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many species parental care is an energetically demanding process. This is especially true for species that nurse or feed their offspring. To meet the high energy needs of parental care, individuals often increase their metabolic rate. In insects, juvenile hormone (JH) may be involved in the increase of metabolic rates. To test this hypothesis, I manipulated JH levels in female burying beetles (Nicrophorus orbicollis), an insect which provides parental care and has high levels of JH in the hemolymph during parental care. To manipulate JH levels, fluvastatin or methoprene was applied topically underneath the elytra of each beetle daily after the first egg was observed up until the emerence of the larvae. Fluvastatin was used to reduce JH levels, while methoprene was used to increase JH levels. The control females received acetone underneath the elytra. The metabolic rates while providing parental care did not differ between the JH treatment groups nor did the control female's metabolic rates while being active differ among different stages of reproduction. My results suggest therefore that JH levels may not affect metabolic rates in burying beetles.

This book was released on 2012-12-06 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria 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 instruments are geared to measure in grams, while the forces commonly encountered in stUdying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with 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 laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which may be applicable for use in biology laboratory courses.
Download or read book Insects at Low Temperature written by Richard Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of insects at low temperature is a comparatively new field. Only recently has insect cryobiology begun to mature, as research moves from a descriptive approach to a search for underlying mechanisms at diverse levels of organization ranging from the gene and cell to ecological and evolutionary relationships. Knowledge of insect responses to low temperature is crucial for understanding the biology of insects living in seasonally varying habitats as well as in polar regions. It is not possible to precisely define low temperature. In the tropics exposure to 10-15°C may induce chill coma or death, whereas some insects in temperate and polar regions remain active and indeed even able to fly at O°C or below. In contrast, for persons interested in cryopreservation, low temperature may mean storage in liquid nitrogen at - 196°C. In the last decade, interest in adaptations of invertebrates to low temperature has risen steadily. In part, this book had its origins in a symposium on this subject that was held at the annual meeting of the Entomological Society of America in Louisville, Kentucky, USA in December, 1988. However, the emergence and growth of this area has also been strongly influenced by an informal group of investigators who met in a series of symposia held in Oslo, Norway in 1982, in Victoria, British Columbia, Canada in 1985 and in Cambridge, England in 1988. Another is scheduled for Binghamton, New York, USA (1990).
Download or read book Insect Diapause written by David L. Denlinger and published by Cambridge University Press. This book was released on 2022-02-03 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Available in PDF, EPUB and Kindle. Book excerpt: The publication of the extensive seven-volume work Comprehensive Molecular Insect Science provided a complete reference encompassing important developments and achievements in modern insect science. One of the most swiftly moving areas in entomological and comparative research is endocrinology, and this volume, Insect Endocrinology, is designed for those who desire a comprehensive yet concise work on important aspects of this topic. Because this area has moved quickly since the original publication, articles in this new volume are revised, highlighting developments in the related area since its original publication. Insect Endocrinology covers the mechanism of action of insect hormones during growth and metamorphosis as well as the role of insect hormones in reproduction, diapause and the regulation of metabolism. Contents include articles on the juvenile hormones, circadian organization of the endocrine system, ecdysteroid chemistry and biochemistry, as well as new chapters on insulin-like peptides and the peptide hormone Bursicon. This volume will be of great value to senior investigators, graduate students, post-doctoral fellows and advanced undergraduate research students. It can also be used as a reference for graduate courses and seminars on the topic. Chapters will also be valuable to the applied biologist or entomologist, providing the requisite understanding necessary for probing the more applied research areas. - Articles selected by the known and respected editor-in-chief of the original major reference work, Comprehensive Molecular Insect Science - Newly revised contributions bring together the latest research in the quickly moving field of insect endocrinology - Review of the literature of the past five years is now included, as well as full use of data arising from the application of molecular technologies wherever appropriate
Download or read book Insect Biochemistry and Function written by D. J. Candy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a considerable upsurge in interest in insect bio chemistry and physiology in recent years and this has been reflected in a notable expansion in the number of original papers in this field. Whereas insect physiology has tended to receive ample attention from reviewers, the same has not always been true for the more biochemical aspects of insect research. This book is a venture to help redress the balance. No attempt has been made to cover all aspects of insect biochemistry, but rather a few topics have been selected which seemed to us to merit a review at the present time. One reason for this increased interest in insect biochemistry is perhaps the growing realization that insects can be very useful organisms to act as model systems for the experimental study of general biochemical principles. One remembers, for instance, that Keilin's perceptive observations on the flight muscles of living bees and wax moths led to his discovery of the cytochromes. The fundamental unity of biochemistry has long been accepted as a dogma by the faithful and the insect kingdom provides no exception to it. The main biochemical processes in insects are being revealed as essentially the same as in other life forms but, as so often found in comparative biochemistry, there are interesting variations on the central theme.
