A propos du livre

Présentation de l'éditeur

During recent years there has been increasing demand for short courses in elementary entomology. For several years past the authors have been endeavoring to present such courses to their students, but have encountered the difficulty that no textbook was available which met their needs. This book is, therefore, the authors effort to furnish such a text for beginners, and if it is found useful to them and to the increasing number of teachers who are endeavoring to instruct them in the subject, the authors will feel well repaid. The work is confessedly very largely a compilation from the works of others (as, indeed, any such work must be), and it is obvious that many errors and defects may have been overlooked, although the authors have spared no pains to eliminate them. To those who observe such shortcomings, or who may be able to offer suggestions for the improvement of the book when revised, the authors will be under great obligation. It was originally intended to include several chapters treating of the various insect pests affecting crops and domestic animals, but it was found that such a work would be too cumbersome; indeed, it is usually not possible to cover both elementary and economic entomology in a single course. The economic side of the subject has, however, been made the dominant note in the following pages, and the forms discussed are mostly those of economic importance. There is a popular belief, often held by young agricultural students, that the chief subject matter of a course in entomology should be a discussion of the common injurious insects. Experience has shown that such an idea is fallacious, and that, from the standpoint of practical utility as well as from that of general culture, a knowledge of the structure, habits, and classes of insects in general is much the more important phase of entomology for academic study.
