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.

Social insects are among the most successful and ecologically important animals on earth. The lifestyle of these insects has fascinated humans since prehistoric times. These species evolved a caste of workers that in most cases have no progeny. Some social insects have worker sub-castes that are morphologically specialized for discrete tasks. The organization of the social insect colony has been compared to the metazoan body. Males in the order Hymenoptera (bees, ants and wasps) are haploid, a situation which results in higher relatedness between female siblings. Sociality evolved many times within the Hymenoptera, perhaps spurred in part by increased relatedness that increases inclusive fitness benefits to workers cooperating to raise their sisters and brothers rather than reproducing themselves. But epigenetic processes may also have contributed to the evolution of sociality. The Hymenoptera provide opportunities for comparative study of species ranging from solitary to highly social. A more ancient clade of social insects, the termites (infraorder Isoptera) provide an opportunity to study alternative mechanisms of caste determination and lifestyles that are aided by an array of endosymbionts. This research topic explores the use of genome sequence data and genomic techniques to help us explore how sociality evolved in insects, how epigenetic processes enable phenotypic plasticity, and the mechanisms behind whether a female will become a queen or a worker.

Arthropods are important to worldwide agriculture, food safety, human health, and energy production. Besides their practical significance, various species represent excellent model systems for biological investigations of evolution, development, physiology, reproduction, and social interaction. For these reasons, arthropod genomics is receiving increasing attention from researchers around the globe. Protocols for Cytogenetic Mapping of Arthropod Genomes is a collection of up-to-date, detailed protocols for physical chromosome mapping and their applications for studying genome organization and evolution in insects and ticks. This book brings together the expertise of cytogeneticists working on diverse groups of arthropods. Each chapter demonstrates approaches to tissue dissection, chromosome preparation, fluorescence in situ hybridization, and imaging. The book is a timely and complementary effort to the i5K initiative, which will obtain whole-genome sequences for 5,000 insect and related arthropod species. This comprehensive resource provides cytogeneticists with the necessary background and protocols to understand and develop chromosome-based genome assemblies from such whole-genome sequence data.

Entomology is a super science, embracing interdisciplinary approaches in genomics, proteomics, and interdependent fields of biochemistry, physiology, molecular entomology, and biotechnology. An urgent need to manage available resources for the benefit of the planet and humankind has led to remarkable progress since publication of the fruit fly genome in 2000. “Short Views on Insect Genomics and Proteomics” presents multiple perspectives of recognized experts from around the world in genomics, bioinformatics, molecular biology, biochemistry, physiology, and immunology, emphasizing fast-moving areas of current research on insects and other arthropods. Concise, accessible, topical reviews include body lice and white fly genome projects, aphid phenotypic plasticity, insect regulatory genomics, the complex tick sialome, protein expression systems, therapeutic potential of insect antimicrobial peptides, nanoparticle insecticides, and novel uses for recombinant and synthetic spider silks.

The Saccharinae clade of the Poaceae (grass) family of flowering plants includes several important crops with a rich history of contributions to humanity and the promise of still-greater contributions, as a result of some of the highest biomass productivity levels known, resilience to drought and other environmental challenges that are likely to increase, amenability to production systems that may mitigate or even reverse losses of ecological capital such as topsoil erosion, and the recent blossoming of sorghum as a botanical and genomic model for the clade. In Genomics of the Saccharinae, advances of the past decade and earlier are summarized and synthesized to elucidate the current state of knowledge of the structure, function, and evolution of the Sorghum, Saccharum, and Miscanthus genera, and progress in the application of this knowledge to crop improvement. As a backdrop, it is important to understand the naturally occurring diversity in each genus, its organization and distribution, and its evolutionary history. Genomic tools and methods for Saccharinae biology and improvement have improved dramatically in the past few years – a detailed summary of these tools and their applications is a central element of this book. Application of genomic tools to priorities in crop improvement, including understanding and manipulating plant growth and development, composition, and defense, as well as increasing the quality and productivity of seed/grain, sugar, biomass, and other value-added products under a range of conditions and inputs, are addressed. In particular, as the first native African crop to emerge as a genomic model, sorghum offers an excellent case study of challenges and opportunities in linking new advances in biosciences to solving some of Africa’s major agricultural problems. Several members of the clade, exemplified by Sorghum halepense (Johnsongrass) offer insights into weediness and invasion biology. The first sequence for a member of the clade, sorghum, as well as progress and challenges toward sequencing of additional members and the new opportunities that this will create, are also explored. Indeed, the very complexities that have hindered study of some clade members also offer intriguing opportunities to gain insight into fundamental questions such as roles of polyploidy in agricultural productivity and post-polyploidy evolution.

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.
