Book Description
In India, the production to tropical tasar silk remained next to mulberry silk for decades, constituting about 4 per cent of the total silk production. Here is an ever increasing demand for tasar silk owing to its strength, lustre and copper brown colour. The tasar silk production has stagnated and declined in the recent past through the demand is increasing. The important reasons for low production are attributed to traditional method of silkworm rearing on all trees in natural habitat, which exposes the larvae to a number of predators, parasites and diseases apart from natural vagaries. The wild sericigenous insects like tasar silkworms have in due course of time came to stay as semi domestic for the regular efforts and interests that revolved round its economic utility. Age-old craft lived with the age-old practices linked with the culture and tradition of the aboriginals; has not allowed the industry to take a commercial shape and spread. However, due stress on the application of 4 Ms, viz., man, material, machine and management need to be emphasized towards enhancing quality linked production. Considering the overall potentiality of wild silkmoths in India, the technology perfection and its adoption could go a long way in harnessing the available flora for rearing tasar silkworms which in turn can be expected to increase the cocoon productivity. In this book emphasis has been given on the types of cocoon, quality and quantum of cocoon production and introduction of improvised seed technology package. This is expected to help the readers a systematic and scientific way of cultivating the tasar. Discussion has been made as to the significance of tropical tasar culture for sustainable development. Relevant detailed references, illustrations and tables with exhaustive index had an enduring appeal for the sericulturists, biotechnologists, technocrats and students of sericulture background. Contents Chapter 1: Introduction; Chapter 2: Silk Scenario; Chapter 3: Taxonomic Profile of Silkworms; Chapter 4: Development and Biometry; Chapter 5: Biometry and Typology; Chapter 6: The Future Scenario.

Book Description
Mulberry (Morus spp.) is an important horticultural plant in the sericulture industry. It belongs to the family Moraceae. The leaf of mulberry is used to feed the silkworm Bombyx mori L. It is also used as a fodder. Due to its economic and agricultural importance, mulberry is cultivated in many parts of the world. An estimated 60% of the total cost of silk cocoon production is for production and maintenance of mulberry plants. Therefore, much attention is needed to improve the quality and quantity of mulberry leaves. It is vital to increase the production of superior quality mulberry leaves with high nutritive value for the sericulture industry. Although a lot of research is going on in mulberry, very little effort has been made to compile the results of this research in a single book. This book provides an update of recent research works going on in this plant. It describes the taxonomy, conservation of germplasm, genetic diversity of various mulberry species, application of breeding techniques to improve the quality of mulberry, in vitro conservation, application of tissue culture techniques to improve mulberry species, production of haploids and triploids in mulberry and improvement of abiotic stress adaptive traits in mulberry with relevance to adaptiveness to global warming.

Book Description
Organisms are continually challenged to regulate and maintain functional capacities as their thermal environment changes. Adjustment to temperature change is evident both phenotypically in individual organisms and genotypically in the evolution of species. This volume addresses thermal adaptation by bringing together many of the leading researchers in thermal biology, with backgrounds spanning the disciplines of molecular biology, cell biology, physiology, zoology, ecology and evolutionary biology. The responses of many species to temperature are discussed in depth, through the molecular, cellular, organismal, population, and ecosystem levels. This text stands as an important contribution to the study of temperature adaptation.

Book Description
This book is a compilation of writings focused on conventional and unconventional insect products. Some of these products are commercials successes, while others are waiting to be launched and are the potential produce of the future. In addition to the well known products honey, mulberry silk, and lac, the book primarily concentrates on silk producing insects other than the mulberry silkworm, insects as food, as sources of medicines, pest and weed managers, and as pollinators. The book highlights the all pervasive role of insects in improving human lives at multiple levels. Accordingly, while most books on insects concentrate on how to limit growth in their population, it instead focuses on how to propagate them. In each chapter, the book brings to the fore how insects are far more beneficial to us than their well publicised harmful roles. This book approaches both unconventional and conventional insect products, such as honey, silk and lac in much more depth than the available literature. It investigates different aspects of the production of these insects, such as the related processes, problems and utilities, in dedicated chapters. Because this book deals with the production of insects or their produce, it has been named Industrial Entomology, perhaps the only book that truly reveals the tremendous potential of insects to help humans live better lives. Based on the research and working experience of the contributors, who are global experts in their respective fields, it provides authentic, authoritative and updated information on these topics. The book offers a unique guide for students, teachers, policy planners, small scale industrialists, and government ministries of agriculture and industry across the globe. It will provide a much required stimulus to insect appreciation and generate enthusiasm for research and the broader acceptance for insect produce. Hopefully, it will also present the Indian perspective on these topics to a global readership.
