Book Description
Insects and non-insect pests are responsible for causing extensive damage to crops in the field and to grains and stored products in the warehouses and godowns, which necessitates their control. In this book, the author has given:- Detailed account of major insect and non-insect pests of economically important field and horticultural crops and possible measures of their control. Information about household pests, which damage human possessions, as well as insect and non-insect pests, which either cause diseases or transmit various diseases in plants, livestock and humans. A list of minor pests of each crop, which may attain the level of major pests when conditions become favorable for them. List of insecticides approved by the Government of India for use as spray chemicals and granular insecticides and the dosage for their use. The text is substantiated with many, fine hand-drawn illustrations, depicting the nature of damage and life cycle of the pests, which is the highlight of this book. The book is intended primarily for the Under Graduate students of Agriculture, but it will be immense use for the Post Graduate students of Agriculture, officials working in the Department of Agriculture, those interested in scientific farming and for the general public.

Book Description
The second edition of this widely used manual has been revised and updated. Some drawings and illustrations have been replaced and new ones added. Suggestions have been made to divide the manual into two separate editions-one, on the study of insects and related forms; the other on the study of plant diseases. However, many of the studies involve both these fields of plant protection. The authors believe that in an applied introductory course their integration gives the students a much broader basis of understanding the problems involved in diagnosing and controlling plant health problems. We therefore, have decided to retain the integrated format.

Book Description
Insects represent over half of the planet’s biological diversity. This popular textbook provides a comprehensive introduction to this extraordinary diversity, and places entomology central to the theory and practice of evolutionary and ecological studies. Fully revised, this fifth edition opens with a chapter concerning the popular side of insect studies, including insects in citizen science, zoos and butterfly houses, and insects as food for humans and animals. Key features of insect structure, function, behaviour, ecology and classification are integrated with appropriate molecular studies. Much of the book is organized around major biological themes: living on the ground, in water, on plants, in colonies, and as predators, parasites/parasitoids and prey insects. A strong evolutionary theme is maintained throughout. There is major revision to the chapter on systematics and a new chapter, Insects in a Changing World, includes insect responses to, and the consequences of, both climate change and human-assisted global alterations to distributions. Updated ‘Taxoboxes’ demonstrate topical issues and provide concise information on all aspects of each of the 28 major groupings (orders) of insects, plus the three orders of non-insect hexapods. New boxes describe a worrying increase in insect threats to landscape and commercial trees (including eucalypts, palms and coffee) and explain the value of genetic data, including evolutionary developmental biology and DNA barcoding, in insect biodiversity studies. The authors maintain the clarity and conciseness of earlier editions, and extend the profuse illustrations with new hand-drawn figures. Over 50 colour photographs, together with the informative text and an accompanying website with links to video clips, appendices, textboxes and further reading lists, encourage a deeper scientific study of insects. The book is intended as the principal text for students studying entomology, as well as a reference text for undergraduate and graduate courses in the fields of ecology, agriculture, fisheries and forestry, palaeontology, zoology, and medical and veterinary science.

Book Description
Contemporary Insect Diagnostics aids entomologists as they negotiate the expectations and potential dangers of the practice. It provides the reader with methods for networking with regulatory agencies, expert laboratories, first detectors, survey specialists, legal and health professionals, landscape managers, crop scouts, farmers and the lay public. This enables the practitioner and advanced student to understand and work within this network, critically important in a time when each submission takes on its own specific set of expectations and potential ramifications. Insect diagnosticians must be knowledgeable on pests that affect human health, stored foods, agriculture, structures, as well as human comfort and the enjoyment of life. The identification and protection of the environment and the non-target animals (especially beneficial insects) in that environment is also considered a part of insect diagnostics. Additionally, Integrated Pest Management recommendations must include any of a variety of management tactics if they are to be effective and sustainable. This greatly needed foundational information covers the current principles of applied insect diagnostics. It serves as a quick study for those who are called upon to provide diagnostics, as well as a helpful reference for those already in the trenches. Includes useful case studies to teach specific points in insect diagnostics Provides problem-solving guidance and recommendations for insect identification, threat potential, and management tactics, while accounting for the varying needs of the affected population or client Contains numerous color photos that enhance both applicability and visual appeal, together with accompanying write-ups of the common pests

Book Description
The 38 chapters of this Field Manual provide the tools required for planning experiments with entomopathogens and their implementation in the field. Basic tools include chapters on the theory and practice of microbial control agents, statistical design of experiments, equipment and application strategies. The major pathogen groups are covered in individual chapters (virus, bacteria, protozoa, fungi, nematodes). Subsequent chapters deal with the impact of naturally occurring and introduced exotic pathogens and inundative application of microbial control agents. The largest section of the Manual is composed of 21 chapters on the application and evaluation of entomopathogens in a wide range of agricultural, forest, domestic and aquatic habitats. Mites and slugs broaden the scope of the book. Supplementary techniques and media for follow-up laboratory studies are described. Three final chapters cover the evaluation of Bt transgenic plants, resistance to insect pathogens and strategies to manage it, and guidelines for evaluating the effects of MCAs on nontarget organisms. Readership: Researchers, graduate students, practitioners of integrated pest management, regulators, those doing environmental impact studies. The book is a stand-alone reference, but is also complementary to the laboratory-oriented Manual of Techniques in Insect Pathology and similar comprehensive texts.
