Agricultural crops suffers a collosal loss due to ravages of insects and diseases thus causing a serious threat to our agricultural production. The insects and diseases cause over Rs. 29000 crores crops loss per annum and Helicoverpa insect alone cause losses around Rs. 35,00 crores. This situation has been caused by indiscriminate use of synthetic poisonous chemicals resulting in development of resistance problem among insects to insecticides, residue hazards of pesticides, upsetting of balance in nature and resurgence of treated populations. Considering all these drawbacks, many components of the IPM concept were developed in the late nineteenth and early twentieth centuries and biopesticides and bioagents were placed as an important tool in pest management strategies which are practical, economical, eco-friendly and protective for both public health and the environment. It is in this context the editor has tried to consolidate all available upto date information on biopesticides and bioagents in the form of a book "Biopesticides and Bioagents in Integrated Pest Management of Agricultural Crops" which deals with current status of the views of significant informations and crucial advances made by the scientific community in all areas of research. For systematic presentation, this compendium has been divided into 17 chapters covering all aspects of biopesticides and bioagents (i.e. parasites, predators, insect pathogens and sex pheromones) and plant products including neem. The purpose of the present treatise before you is only to bring together the basic and applied facts available and to re-evaluate and review the past researches and the new and current discoveries. This book is therefore very timely and with great significance in view of encouragement given to organic farming for sustainable agriculture. It is hoped that this book would be very useful to teachers, researchers and students etc.
