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.

History of Entomology in India Entomology is a biological science dealing with a specific group of organisms, the insects. Man originated about a million years ago, and insects at least 500 million years ago. Insects constitute the largest Class of the whole living organisms and about 72 per cent of all living animals are insects with 9-15 lakh known species. Insects are omnipresent and each crop we cultivate is being attacked by at least a dozen of insect species called as pests. Apart from the pest insects there are several productive and useful insects. Insects are considered as one of the major constrain in increasing agricultural productivity. Hence it is important to understand about the insects, their biology, classification and management. Our earliest knowledge about insects dates back to 6000 yrs. as our Indian ancestors were well versed in the art of rearing silk worms and weaving silk cloth. Even during 3870 BC an Indian king sent various silken materials as presents to a Persian king.

Mites pose a serious problem to plants worldwide, attacking crops and spreading disease. When mites damage crops of economic importance the impacts can be felt globally. Mites are among the most diverse and successful of invertebrates, with over 45,000 described species, with many more thousands to be discovered. They are responsible for a significant portion of the losses of crops for food, fibre, industry and other purposes, and require expensive and often controversial pest control measures. Understanding these mites is vital for entomologists, pest researchers, agronomists and food producers. Knowledge of mite pests helps to inform control strategies and optimize the production of economic plants and the agrarian economy. This encyclopedia provides a thorough coverage of the mites and the problems they cause to crops, yet it is easily searchable, organised by mite species and subdivided into helpful headings. It takes a worldwide view of the issue of mites injurious to economic plants, describing mites prevalent in different regions and discussing control methods appropriate in different environments. This book provides an encyclopaedic reference to the major mites, described by family in terms of their internal and external morphology, bio-ecology and family systematics. Methods of mite collection and laboratory study is described, as well as species diagnostic characteristics, worldwide distribution, host plants, identification by the type of damage they cause and control strategies, including chemical and biological intervention and integrated pest management measures. Mites of the following families are included: (Eriophyoidea, Tarsonemidae, Tuckerellidae, Tenuipalpidae, Tetranychidae, Acaridae, Penthaleidae). Mites of Economic Plants is an important resource for students of entomology and crop production, and as a thorough reference guide for researchers and field workers involved with mites, crop damage and food production.
