An introduction to all aspects of modern entomology, this text provides the student with a basic understanding of insect structure, function, development, classification and phylogeny. Chapters have been revised in this edition to take account of developments such as pheromones, thermoregulation and views on cladistics. The book also introduces readers to the ways in which insects exemplify many phenomena of general biological interest. All major insect modes of life are discussed, including the relations of insects to plants and micro-organisms, their role as predators and parasitoids, and their adaptations to aquatic and social lifestyles. In a chapter new to this edition, the biology of insect populations is considered in some detail, with special emphasis on quantitative aspects of population dynamics and predator-prey interactions, together with related subjects such as competition density regulation and the stability, diversity and succession of insect populations. The book is suitable for undergraduate students of entomology and other biological science courses, such as zoology, agriculture and horticulture.

seem as appropriate now as the original balance was when Dr A. D. Imms' textbook was first published over fifty years ago. There are 35 new figures, all based on published illustrations, the sources of which are acknowledged in the captions. We are grateful to the authors concerned and also to Miss K. Priest of Messrs Chapman & Hall, who saved us from many errors and omissions, and to Mrs R. G. Davies for substantial help in preparing the bibliographies and checking references. London O. W. R. R. G. D. May 1976 Part III THEORDERSOFINSECTS THE CLASSIFICATION AND PHYLOGENY OF INSECTS The classification of insects has passed through many changes and with the growth of detailed knowledge an increasing number of orders has come to be recognized. Handlirsch (1908) and Wilson and Doner (1937) have reviewed the earlier attempts at classification, among which the schemes of Brauer (1885), Sharp (1899) and Borner (1904) did much to define the more distinctive recent orders. In 1908 Handlirsch published a more revolutionary system, incorporating recent and fossil forms, which gave the Collembola, Thysanura and Diplura the status of three independent Arthropodan classes and considered as separate orders such groups as the Sialoidea, Raphidioidea, Heteroptera and Homoptera. He also split up the old order Orthoptera, gave its components ordinal rank and regrouped them with some of the other orders into a subclass Orthopteroidea and another subclass Blattaeformia.
