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.

In sericulturally advanced countries, the seed production technologies have been perfected to its highest level. Though, in India silkworm seed production is practiced since decades, it is yet to be standardized to its perfection. To meet the requirement of seed to Indian sericulture farmers, the country requires more than 30 crore disease free commercial silkworm seed. However, all the agencies in the country together produce only 24 crore disease free layings (Dfls) and thus there is production shortage of some six crore disease free layings. In this backdrop, this book is prepared with the objective to explain the various strategies to be adopted in the production of better quality and higher quantity of silkworm eggs. The book "Silkworm Egg Science: Principles & Protocols" tries to motivate and assist in its efforts to unveil secrete of the various existing problems related to silkworm egg to increase production, productivity and quality of cocoons. Spread over ten chapters, the book has wide coverage on disinfection and hygiene, egg production technologies, embryonic development, egg diapause and biochemical modulations, preservation of eggs, hibernation schedules, artificial hatching of eggs for rearing of silkworm in appropriate season, methods of incubation, adaptation to changing environment besides prevention and control of pebrine disease of eggs and pests to achieve sustained and quality silkworm eggs and stable cocoon crop. The technical components are meticulously incorporated in this book to make it fairly comprehensive reference material. The book is designed to address wide range of readers, experts, university teachers, students, researchers, technologists, policy makers and fulfill the hopes and aspirations of all those engaged in sericulture in general and egg production in particular. The information furnished in this book will be of immense importance not only to Indian sericulture but also to South Asian and African countries and will find an application at all levels of sericulture.

The main criteria of consolidation of this book "Guide for Insect Morphology" (Objective based) is to fulfil the need of the students those who are appearing for JRF, SRF, ARS, NET, Civils and several other competitive exams. To consolidate this book it has taken several days to collect, edit and update the vast literatures from various reference books, journals and different websites. Due to compilation of all the topics into one books it may be chance of missing some of the things which will be most useful to the students, so we try to consolidate the basic subject (Insect Morphology) which are at most important in the entomology which will give a vast knowledge within a short period of time instead reading several books and wasting the precious time. It is one of the most useful book to the aspirants those who are appearing for different competitive exams. This book consists of total 4 parts. Part- I dealing with Insect Morphology, consisting 12 Chapters, each chapter will give the vast knowledge about the subject, Part- II deals with the Different Institutions in India, Journals and Magazines present worldwide, it consists of 7 Chapters. Part -III consists of Tables in which classification and differences are present. Part-IV deals with the Previous year question papers.
