Handbook of Agricultural Entomology by Helmut van Emden is a landmark publication for students and practitioners of entomology applied to agriculture and horticulture. It can be used as a reference and as a general textbook. The book opens with a general introduction to entomology and includes coverage of the major insects (and mites) that cause harm to crops, livestock and humans. The important beneficial species are also included. Organisms are described in a classification of insect Orders and Families. The emphasis is on morphological characters of major taxonomic divisions, “spot characters” for the recognition of Families, and the life histories, damage symptoms and economic importance of the various pest species. The book is beautifully illustrated in full colour with more than 400 figures showing both the organisms and the damage caused to plants with diagnostic characters indicated by arrows. Coverage is world-wide and includes much material stemming from the vast personal experience of the author. A companion website with additional resources is available at www.wiley.com/go/vanemden/agriculturalentomology

Excerpt from A d104-Book of Agricultural Entomology: Being a Guide to Methods of Insect Life and Means of Prevention of Insect Ravage; For the Use of Agriculturists and Agricultural Students The first edition of this little volume consisted of ten lectures delivered in 1883 at the Institute of Agriculture of South Kensington, in compliance with the request of the Director that I would prepare some simple and plain information regarding the methods of life of crop insects, and means of prevention of their ravages, such as might be of service to school teachers. At that time there appeared to he but little call for such a compilation, but I complied with the request in the hope that the work might be useful for farm service; and that in its published form it might he carried to the field, or taken up at an odd minute, and give a little information without burdening the reader with a need of looking elsewhere for explanations.

Agricultural Entomology presents a global view of the insect groups that are of major significance to human resources. "Agriculture" in this broad sense includes plants grown for food, horticultural field crops, and other ornamentals. Information is also included on insect pests of stored products, forest resources, and livestock, although in less detail. The book is intended for use as a college text and reference and assumes a basic knowledge of entomology but is also of great value outside the classroom for its comprehensive and detailed approach. There is a chapter on beneficial insects, including pollinators, honeybees, silkworms, and insects from which shellac and cochineal are made. Hundreds of high-quality line drawings and black-and-white photographs illustrate the insects, and an illustrated glossary and indexes of scientific and common names are provided. Almost all countries of the world are undergoing agricultural diversification programs with the introduction of new and exotic crops. Yet most books on insect pests restrict coverage to one country or region or to the tropics or temperate zones. The global approach of Agricultural Entomology emphasizes the similarities and important differences between insect pests of the major continents. It thus brings attention to insect species that might well spread as pests to new geographical areas. Closely related species are also treated, highlighting problems of control that could result from unsubstantiated identifications. Agricultural Entomology is a valuable resource for growers and gardeners interested in the developing field of integrated pest management. With copious information on the biology of insects around the globe, this authoritative and comprehensive book is an essential tool for anyone interested in understanding both the foes and allies of the insect world.

Entomology as a branch of biological science has undergone rapid expansion and development in recent decades. Greater emphasis is now placed on topics such as modelling and biochemical techniques, with new approaches to the study of insect behavior and insecticide efficacy making inroads into traditional approaches. Aimed at advanced undergraduate and postgraduate students in entomology and pest management, this book aims to integrate the new approaches and technologies with traditional and well-proven methods. It provides a critical analysis and evaluation of methods available, through reference to general principles, but emphasis is also placed on providing detailed descriptions of methods and their applications.
