East African forests, among the world’s most biologically rich and diverse, are subject to multiple pressures, including insects. As the first work to focus exclusively on East African forest insects, this monograph distils 135 years of scientific and historical literature extending from before the colonial era to the present into an authoritative survey of this region’s major pests of trees and wood, as well as their antagonists.

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.

Invasive species, generally, affect economically important crops, thus affecting the livelihoods of millions of people along crop value chains. Typically, invasive species have high migratory capabilities and, because of plant material exchanges made during trade, they cannot be contained by one country. Usually, African countries react after a pest has invaded and established itself in the country, making the cost of mitigating the pest even more expensive. This book presents a pan-African view of the impacts of invasive insect pests on agriculture and of how invasive species impact on productivity in Africa. It not only describes their importance, but also presents a diversity of research findings in the field, ranging from the use of early warning and monitoring systems for quarantine purposes, agricultural extension, all the way to control strategies. The IPM arsenal presented in this book includes the use of botanical bioactive compounds, semiochemicals, resistant varieties, biological control agents such as entomopathogens, endophytes, predators, and natural enemies. Aspects of technology transfer strategies, regional coordination, and farmers’ perceptions have not been overlooked, because these affect the adoption of mitigation strategies. The book also presents measures that would help agricultural research services to estimate the damage and take actions for preparedness and readiness to face invasive insect pests. This starts with a basic knowledge of taxonomy to enable concerned persons to describe the insects and the vast inventory of affected crops. Physiological and ecological aspects of invasive pests are strongly highlighted to strengthen Integrated Pest Management Strategies. The threat of invasive species will remain permanent; therefore, the book encourages knowledge exchange and collaboration between researchers and scientists on the continent, while encouraging the establishment of a platform or a fund for preparedness and rapid response.

In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.
