DOWNLOAD EBOOKIn his preface to early editions of this book, the late Dr. A. D. Imms said that he intended it to be an elementary account of entomology as a branch of general biology. He had especiaHy in mind the needs of university students of zoology and agriculture, as weH as those intending later to specialize in entomology, and he suggested that the book might also interest teachers of advanced biology in schools. These general aims and the balance between the different aspects of the subject have changed linIe in this and in our previous revision. We have, however, tried to bring the present edition up to date on the lines of our revised tenth edition of Imms' General Textbook 0/ Entomology, published in 1977. The text has been entirely re-set and eleven illustrations have been replaced by new figures. The same orders of insects are recognized as in the last edition, but the sequence in which the Endopterygote groups appear has been changed to reflect more accurately their probable evolutionary relationships. Many small changes and some addi tions have been made in the physiological sections, the chapter on the origin and phylogeny of insects has been rewritten, and a new bibliography provides a selection of modern references for the in tending specialist. It has been our object to make these alterations without materially increasing the length of the book or its level of difficulty.

DOWNLOAD EBOOKseem 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.

DOWNLOAD EBOOKThe present edition may be regarded as a descendant, much changed and greatly enlarged, of the late Dr A. D. Imms' Outlines of Entomology, first published in 1942. This went through three further editions without much change, but after the death of the original author a fifth, revised edition by Professor o. W. Richards and myself appeared in 1959 and a sixth in 1978. The book now appears in a considerably extended version in which I have tried to provide a more balanced introduction to the whole field of modern entomology by dealing with several aspects of the subject not discussed at all in previous editions. Thus, in addition to innumerable lesser changes in the sections on insect structure, function, development, classification and phylogeny, I have completely recast the earlier chapter on some important modes of life in insects. This now includes a far wider range of biological topic;s well exemplified by the insects and should, I hope, appeal not only to, those already dedicated to entomology but also to others with more general biological interests. A completely new chapter on the biology of insect populations has also been added and may serve to indicate the debt which modern ecological theory owes to work on insect populations. It should hardly be necessary to apologize for introducing a certain amount of elementary mathematics into this account of a subject which is now among the most highly quantitative of biological disciplines.

DOWNLOAD EBOOKPeriodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland in The Changing Flora and Fauna of Britain, also edited by Professor David L. Hawksworth CBE. Now, in The Changing Wildlife of Great Britain and Ireland, he has gathered together some of the original and also new contributors to review changes since that time and look to the future. Contributions range from viruses, diatoms, fungi, lichens, mites and nematodes; through butterflies, dragonflies, flies and slugs; to flowering plants, ferns, mammals, birds and fish. The state of knowledge in different groups is assessed, and the effectiveness of statutory and other measures taken to safeguard wildlife considered. The picture is far from bleak, ameliorating sulphur dioxide levels have benefited sensitive lichens and mosses in a dramatic way, water quality improvement has been beneficial, there have been few certain extinctions and rediscoveries of species thought to have been lost. Biodiversity Action Plans have also benefited targeted species, but habitat restoration and management for some is not always good for others. But there are worrying trends in declining populations, with an increasing number being regarded as threatened or endangered, especially in agricultural areas, and where woodland management has changed, particular threats from introduced species, and concern over the effects of climate change. Some of the smaller organisms remain poorly known, a situation unlikely to change as expertise in many is scant or being lost. This stock-check and look to the future will be a key source book to conservationists, naturalists, and professional biologists for many years to come.

DOWNLOAD EBOOKGillott’s thorough yet clear writing style continues to keep Entomology near the top of the class as a text for senior undergraduates, and for graduate students and professionals seeking an introduction to specific entomological topics. The author’s long-held belief that an introductory entomology course should present a balanced treatment of the subject is reflected in the continued arrangement of the book in four sections: Evolution and Diversity, Anatomy and Physiology, Reproduction and Development, and Ecology. For the third edition, all chapters have been updated. This includes not only the addition of new information and concepts but also the reduction or exclusion of material no longer considered "mainstream", so as to keep the book at a reasonable size. Based on exciting discoveries made during the previous decade, the topics of insect evolutionary relationships, semiochemicals, gas exchange, immune responses (including those of parasites and parasitoids), flight, and the management of pests have received particular attention in the preparation of the third edition. Overall, more than 30 new or significantly revised figures have been incorporated.

DOWNLOAD EBOOKThe idea of writing this book was conceived when, in the late 1960s, I began teaching a senior undergraduate class in general entomology. I soon realized that there was no suitable text for the class I intended to give. The so-called "general" or "introductory" texts reflected the traditional taxonomic approach to entomology and contained relatively little information on the physiology and ecology of insects. This does not mean that there were no books containing such information. There were several, but these were so specialized and de tailed that their use in an introductory class was limited. I hold a strong belief that an undergraduate general entomology course should provide a balanced treatment of the subject. Thus, although some time should be devoted to taxonomy, including identification (best done in the laboratory, using primar ily material which students themselves have collected, supplemented with specimens from the general collection), appropriate time should be given also to discussion of the evolution, development, physiology, and ecology of in sects. In the latter category I include the interactions between insects and Man because it is important to stress that these interactions follow normal ecological principles. Naturally, the format of this book reflects this belief. The book has been arranged in four sections, each of which necessarily overlaps with the others.
