This book describes the outstanding features of the ecology and bio geography of the Indian region, comprising former British India, Nepal, Bhutan, Ceylon and Burma. It summarizes the results of nearly four decades' studies and field explorations and discussions with students on the distribution of plants and animals, practically throughout this vast area and on the underlying factors. A number of specialists in geology, meteorology, botany, zoology, ecology and anthropology have also actively collaborated with me and have contributed valuable chapters in their respective fields. India has an exceptionally rich and highly diversified flora and fauna, exhibiting complex composition, character and affinities. Although the fauna of the Indian region as a whole is less completely known than its flora, we are nevertheless fairly well acquainted with at least the salient features of its faunal characters to enable us to present a meaningful discussion on some of the outstanding peculiarities of the biogeography of India. A general synthesis of the available, though much scattered, information should prove useful to future students of biogeography throughout the world."

In my book Introduction to High Altitude Entomology, published in 1962, I summa rized the results of eight years' studies, mainly on the Himalaya. I have since then had the opportunity of studying the collections of high altitude insects from the Alps, Carpathians, Caucasus, Urals, Alai-Pamirs, Tien Shan, Altai and other im portant mountains of the world in different museums and institutions in Europe. Through the courtesy and generosity of the Academy of Sciences of the Union of Soviet Socialist Republics, I was also able to personally collect insects and make valuable field observations on the Caucasus, the Alai-Pamirs, Ala-Tau and the Tien Shan mountains. Through comparative studies I have tried to synthesize the fundamental principles of high altitude entomology. I have described here the distinctive characters of the high altitude environment, the ecological specializations of the high altitude insects, their ecological inter relations and the outstanding peculiarities of their biogeography. I have also pre sented here an outline of the high altitude entomology of the principal mountains of the world, with brief accounts of their orogeny, geology and vegetation. This book differs from all other contributions in the field in its comparative ecological approach and in the fact that the main emphasis is throughout on the evolution of the high altitude ecosystem as an integral part of the orogeny. High mountains are, in all parts of the world, important and independent centres of origin and differ entiation of distinctive and highly specialized ecosystems and faunas."

Intensive and extensive cultivation of grapes (Vitis vinifera L.) leads to serious pest problem in vineyards in major grape growing areas of the world. Climatic conditions in India are favorable for high production of table and wine grapes, and thus also for incidence of variety of pests. These include the sucking insect pests namely thrips, hoppers, mealybugs etc., and beetle pests like stem borer, stem girdler, flea beetles, chafer beetles, shot hole borer and several lepidopteron, mites, nematodes and vertebrate pests. Pests of grapes in other countries relevant to Indian conditions are also dealt herewith since they may get introduced in India in future. Up to date information on biology, damage, seasonal development, management practices of the pests are covered in this book. Some of the pest management practices followed in other countries are also given, which will be useful to Indian conditions. Pesticide residue is a serious problem both for export and internal market in grapes. Guideline for pesticide residue management in grapes is also given in this book. The authors have tried to accommodate almost all the important information generated on the grape pests up to 2012. A complete list of grape pests (except disease) occurring in different grape growing regions of the world is also covered in this book which will be ready reckoner for the grape workers. The authors sincerely hope that this book will provide useful information to many entomologists, students working on grapes and the grape growers in the country. It is a pleasure to thank all those people who gave help, suggestions and encouragement in the preparation of our book "The Grape Entomology".

High altitude research is comparatively a recent development. With the notable exceptions of entomology, botany and perhaps some aspects of human acclimatization, our knowledge of high altitude environment is extremely scanty. There is at present no comprehensive handbook on the general ecology of highlands. This book aims at providing such a text for the use of the general scientist, engineer, biologist and university students. It summarizes and critically reviews current developments and focusses atten tion on urgent problems of highland ecology needing future studies. This book has grown out of our explorations and experiences in the highlands of Asia and South America. The results of explorations of the high altitude plants and insects on the Himalaya, Alai-Pamirs, Central Tien Shan and Caucasus by one of us (MSM), discussed in earlier publications, are reviewed here in the light of recent advances. Many years' experience of teaching and research in the University of Sucre (3400 m) and studies at Potosi (4000 m), La Paz and Chacaltaya (5000 m) in Bolivia by the second author (LEG) cover problems in physical chemistry, meteorology, engineer ing and other physical aspects of highland environments."
