Book Description
Great progress has been made in the past decade in the field of sericulture research. Sericulture technique covering various aspects has also advanced greatly. Like agriculture, sericulture, as an industry, requires greater development in research and technology aimed at increased production. This text covers the complete range of subjects with current data relating to mulberry and silkworm. Particular emphasis has been laid on the basic aspects of stable crop of silkworm and various preventive measures against adverse factors. Topics covered include the sericulture industry and its future; mulberry cultivation; silkworm and its strains; silkworm eggs; morphology, physiology, ecology and genetics of the silkworm; diseases of silkworms; rearing of silkworms; cocoon; silkmoth and egg production; and utility of byproducts.

Book Description
While silk derived from silkworm has been of economic importance for centuries, more recently silkworm has been found to have utility in biomedicine. This has attracted attention for expressing eukaryotic recombinant proteins, which require post-translational modifications. In 1985 Dr. Susumu Maeda demonstrated that silkworm larvae could produce a functional human-interferon. Since then various techniques have been developed to express recombinant proteins in silkworm. With the development of the Bombyx mori nucleopolyhedrovirus (BmNPV) bacmid system, which is capable of replicating in both Escherichia coli and Bombyx mori derived cell lines or silkworm, silkworm larvae or pupae have been used for the expression system for recombinant protein production. This method has the advantage of a bacmid, in that it can be easily prepared for sufficient bacmid DNA for subsequent expression in silkworm. It is potentially a big breakthrough in production of recombinant eukaryotic proteins and viruses, which will be a powerful tool in a new proteome era. This volume contributes to the advancement of our knowledge in the subject, for example gene expression systems and silkworm research, and focuses on silkworm biofactories for the recombinant protein production and commercial applications of proteins.

Book Description
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).

Book Description
The pesticide should cause effect on the target pests and be selective enough to spare the non-target beneficial. The book deals with the pesticide toxicity to predators, parasitoids and microbes which are used for pest management in the agroecosystem. The other beneficials exposed to pesticides are pollinators, earthworms, silkworm and fishes. The book contains information on the modes of pesticide exposure and toxicity to the organisms, sub-lethal effects of insecticides and method of toxicity assessment, risk assessment of pesticidal application in the field. The purpose of the work is to compile and present the different procedures to assess pesticide poising in organisms related to the agroecosystem along with discussions on risk assessment procedures with clear comparison of toxicity of pesticides to target pests and non target beneficial organisms.

Book Description
This volume is primarily devoted to the analysis of the integument (epidermis, cuticle), the fat body, the connective tissues, the circulatory and respiratory systems. It discusses the organization and functioning of the insect systems implicated in growth, intermediary metabolism, homeostasis and defence mechanisms. Much of the volume is devoted to anatomical and structural developments, which appear as introductions to corresponding biochemical and physiological aspects. Many diagrams, drawings and photographs accompany the text throughout. Altogether, this volume presents a clear and up-to-date account of the most recent and important discoveries in the fields and shows the extent of progress which is expected in the near future.

Book Description
The Silk Road: A Very Short Introduction is a new look at an ancient subject: the silk road that linked China, India, Persia and the Mediterranean across the expanses of Central Asia. James A. Millward highlights unusual but important biological, technological and cultural exchanges over the silk roads that stimulated development across Eurasia and underpin civilization in our modern, globalized world.

Book Description
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.
