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. Putting the spotlight on the second most numerous order of insects living today, this book provides a summary of cutting-edge studies of the Lepidoptera as an organism in and of itself and as model systems. Leading researchers discuss symbiosis, genomes, sex determination, natural products, ecophysiology, sensory systems, pest control, the sterile insect technique, immunity, and evolution development. 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 pest control and the sterile insect technique extremely important.

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.

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.

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 contains seven chapters divided into two sections. The first section is "Lepidoptera Systematics." It covers introduction classification and external and internal morphology. It also includes the importance and modern approaches of Lepidoptera collection curation and data management. It also describes molecular phylogeny and taxonomy of Lepidoptera for ecological and evolutionary studies. The second section, "Lepidoptera as a Model for Research," describes eyespot color pattern formation mechanism in the peacock pansy, Junonia almana (L.). The complete mitochondrial genome of the American potato tuberworm, Tecia solanivora (Povolny), is presented to study a mitogenome in insects. Lepidoptera are sensitive to physical and climatic changes. Therefore, their taxocenotic and biocenotic study was conducted in three environments, i.e., the grassland, forest, and ecotone of Rucamanque, a forest remnant.
