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.
