Book Description
In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Book Description
Deforestation, soil erosion, desertification, air and water pollution, loss of wildlife habitat, and declining biodiversity are interrelated manifestations of a growing environmental crisis in North Africa that has received relatively little attention from government policymakers and is poorly understood by North African peoples, the international development community, and scholars. In this book a multidisciplinary group of scholars explores the broad range of human activities causing the deterioration of North Africa’s fragile environment, including population pressure and poverty, rapid urbanization, intense competition for land and water, and mismanagement of natural resources. The contributors examine in particular the conflict between economic development and environmental sustainability. They analyze the historical roots of current environmental problems, the underlying socioeconomic causes, potential solutions, and differences in environmental policies among various countries. This is an insightful portrait of a developing region attempting to reconcile traditional methods of land use with growing demands for resources, the exigencies of economic development, and the limitations of its natural resource base.

Book Description
Here is a comprehensive resource on the devastating effect of locust outbreaks on crop production along with valuable coverage of traditional as well as new and emerging control and mitigation strategies. Begining with an introduction to and history of locust attacks, the volume describes the deleterious effects of locusts on crops and delves into both traditional and state-of-the art control and management technologies to combat locust outbreaks, including such advanced technologies as geographical information systems (GIS) and global positioning systems (GPS) and methods such as employing entomopathogenic fungi as a pest control measure. The book also evaluates how climate change has exacerbated the damage from locusts and the environmental ramifications. The book considers the scientific aspect of the role of pheromones on the reproduction of locusts and discusses the culture of using locusts as a food source in some countries. Topically, the volume also considers the influence of the COVID-19 pandemic on locust outbreaks on the world’s economy. This important and unique volume is a highly valuable resource for those working on meeting the challenges of locust invasions and their terrible consequences on crops, societies, and economies.

Book Description
Biological control is the suppression of pest populations using predators, parasitoids and pathogens. Historically, biological control has largely been on a trial-and-error basis, and has failed more often than it has succeeded. However by developing theories based upon fundamental population principles and the biological characteristics of the pest and agent, we can gain a much better understanding of when and how to use biological control. This book gathers together recent theoretical developments and provides a balanced guide to the important issues that need to be considered in applying ecological theory to biological control. It will be a source of productive and stimulating thought for all those interested in pest management, theoretical ecology and population biology.
