Molecular Biology And Genetics Of The Lepidoptera

Numerous and charismatic, the Lepidoptera is one of the most widely studied groups of invertebrates. Advances in molecular tools and genomic techniques have reduced the need for large sizes and mass-rearing, and lepidopteran model systems are increasingly used to illuminate broad-based experimental questions as well as those peculiar to butterflies and moths. Molecular Biology and Genetics of the Lepidoptera presents a wide-ranging collection of studies on the Lepidoptera, treating them as specialized insects with distinctive features and as model systems for carrying out cutting-edge research. Leading researchers provide an evolutionary framework for placing moths and butterflies on the Tree of Life. The book covers progress in deciphering the silkworm genome and unraveling lepidopteran sex chromosomes. It features new information on sex determination, evolution, and the development of butterfly wing patterns, eyes, vision, circadian clocks, chemoreceptors, and sexual communication. The contributors discuss the genetics and molecular biology of plant host range and prospects for controlling the major crop pest genus Helicoverpa. They also explore the rise of insecticide resistance, the innate immune response, lepidopteran minihosts for testing human pathogens and antibiotics, and the use of intrahemocoelic toxins for control. The book concludes with coverage of polyDNA virus-carrying parasitoid wasps, and the cloning of the first virus resistance gene in the silkworm. Understanding the biology and genetics of butterflies and moths may lead to new species-selective methods of control, saving billions of dollars in pesticide use and protecting environmental and human health—making the sections on strategies for pest management extremely important. This book will open up new paths to the research literature for a broad audience, including entomologists, evolutionary and systematic biologists, geneticists, physiologists, biochemists, and molecular biologists.

This book presents a diverse collection of chapters on basic research at the molecular level using Lepidoptera as model systems. This volume, however, is more than just a compendium of information about insect systems in general, or the Lepidoptera in particular. Each chapter is a self-contained treatment of a broad subject area, providing sufficient background information to give readers a sense of the guiding principles and central questions associated with each topic, in addition to major methodologies and findings. Comparisons with other major model systems are emphasized, with special attention given to the fruit fly, Drosophila melanogaster. Topics include: genetics, mobile elements, embryogenesis, silk gland and chorion gene regulation, hormone action, neurobiology, the immune response and engineered baculoviruses. Molecular and developmental biologists at graduate and researcher levels will find this book of great interest.

Lepidoptera Genetics provides a systematic account of the genetics and karyology of Lepidoptera. Topics covered include the use of biometry in genetic studies; population genetics and polymorphism; the rise of industrial melanism; and the evolution of mimicry. The genetics of Rhopalocera and Heterocera is also discussed. This book is comprised of eight chapters and begins with an overview of Lepidoptera species and their genetics, paying particular attention to color and pigmentation, breeding, and resistance to insecticides, as well as the effect of seasonal variations and the environment on Lepidoptera. The next chapter outlines the tenets of genetics that are of value for Lepidoptera research, including particulate heredity, random assortment, sex-linked inheritance, maternal inheritance, and mosaicism. The reader is methodically introduced to the application of biometry to the study of Lepidoptera genetics; the evolution of mimicry in Lepidoptera; and the known heredity of Rhopalocera and Heterocera. The final chapter examines the karyology of Lepidoptera, focusing on the haploid karyotype, polyploidy, chiasmata frequency, supernumerary chromosomes, and sex chromatin. This monograph will be a useful resource for entomologists, geneticists, and biologists.

Developed as an introduction to new molecular genetic techniques, Insect Molecular Genetics also provides literature, terminology, and additional sources of information to students, researchers, and professional entomologists. Although most molecular genetics studies have employed Drosophila, this book applies the same techniques to other insects, including pest insects of economic importance. As a text, as a reference, as a primer, and as a review of a vast and growing literature, Insect Molecular Genetics is a valuable addition to the libraries of entomologists, geneticists, and molecular biologists.

This book provides an overview on the basics in insect molecular biology and presents the most recent developments in several fields such as insect genomics and proteomics, insect pathology and applications of insect derived compounds in modern research. The book aims to provide a common platform for the molecular entomologist to stimulate further research in insect molecular biology and biotechnology. Insects are one of the most versatile groups of the animal kingdom. Due to their large population sizes and adaptability since long they attract researchers’ interest as efficient resource for agricultural and biotechnological purposes. Several economically important insects such as Silkworms, Honey Bee, Lac and Drosophila or Termites were established as invertebrate model organisms. Starting with the era of genetic engineering, a broad range of molecular and genetic tools have been developed to study the molecular biology of these insects in detail and thus opened up a new horizon for multidisciplinary research. Nowadays, insect derived products are widely used in biomedical and biotechnology industries. The book targets researchers from both academia and industry, professors and graduate students working in molecular biology, biotechnology and entomology.

Entomology as a science of inter-depended branches like molecular entomology, insect biotechnology, has made rapid progress. This also implies that there is an urgent need to manage the available resources. In the past five decades, entomology has taken giant steps ahead. The aim of this work is to integrate perspectives across molecular and biochemistry, physiology, reproduction, developmental biology, molecular evolution, genetics and RNAi applications. This century is proclaimed as the Era of Biotechnology and it consists of all types of Mol-Bio-Gen applications, which is an essential component for a thorough understanding of the insect biology. The aim of this work is to provide the comprehensive review of recent research from various geographic areas around the world and contributing authors that are recognized experts in their respective field of Genomic entomology. This Volume emphasizes upon the need for and relevance of studying molecular aspects of entomology in Universities, Agricultural Universities and other centers of molecular research. It will also serve as a landmark source for Insect advance science technology.

The beauty and grace of butterflies have long captivated people around the world, but their diversity and complexity have drawn the special attention of amateur and professional scientists since at least the time of Darwin. Thanks to this long history of research, more is known about butterflies than is known about almost any other group of insects. experts synthesize current knowledge of butterflies to show how the study of these fascinating creatures as model systems can lead to deeper understanding of ecological and evolutionary patterns and processes in general. The 26 chapters are organized into broad functional areas, covering the uses of butterflies in the study of behaviour, ecology, genetics and evolution, systematics, and conservation biology. Especially in the context of the current biodiversity crisis, this book shows how results found with butterflies can help us understand large, rapid changes in the world we share with them - for example, geographic distributions of some butterflies have begun to shift in response to global warming, giving early evidence of climate change that scientists, politicians and citizens alike should heed. Butterflies: Ecology and Evolution Taking Flight offers students, scientists and amateur naturalists a concise overview of the latest developments in the field. Furthermore, it articulates an exciting new perspective of the whole group of approximately 15,000 species of butterflies as a comprehensive model system for all the sciences concerned with biodiversity and its preservation.

This book facilitates an integrative understanding of the development, genetics and evolution of butterfly wing patterns. To develop a deep and realistic understanding of the diversity and evolution of butterfly wing patterns, it is essential and necessary to approach the problem from various kinds of key research fields such as “evo-devo,” “eco-devo,” ”developmental genetics,” “ecology and adaptation,” “food plants,” and “theoretical modeling.” The past decade-and-a-half has seen a veritable revolution in our understanding of the development, genetics and evolution of butterfly wing patterns. In addition, studies of how environmental and climatic factors affect the expression of color patterns has led to increasingly deeper understanding of the pervasiveness and underlying mechanisms of phenotypic plasticity. In recognition of the great progress in research on the biology, an international meeting titled “Integrative Approach to Understanding the Diversity of Butterfly Wing Patterns (IABP-2016)” was held at Chubu University, Japan in August 2016. This book consists of selected contributions from the meeting. Authors include main active researchers of new findings of corresponding genes as well as world leaders in both experimental and theoretical approaches to wing color patterns. The book provides excellent case studies for graduate and undergraduate classes in evolution, genetics/genomics, developmental biology, ecology, biochemistry, and also theoretical biology, opening the door to a new era in the integrative approach to the analysis of biological problems.
