Insects are ubiquitous and are found all over the world, in the Lithosphere, Hydrosphere and Biosphere. According to evidences insects appeared on this planet Earth some 440 million years ago, long before the appearance of man in this world. Because of their dynamic adaptational traits insects have escaped extinction all these years.Insects have the innate ability to adapt themselves to any kind of adverse environmental conditions. The morphology and anatomy of insects, as well as their mode of life are quite important factors that help in the development of traits for adaptation.In this book the authors have given a detailed account of the general aspects of insects, as well as morphology and anatomy of insects. Studies on such aspects about insects are ultimately aimed at devising and adopting physical, mechanical, chemical or biological control measures to combat the insects, which have turned into pests and pose a serious problem to mankind.The text is substantiated with many fine, hand-drawn figures that will help better understanding of the book and make the reading more interesting.
