Although locusts are a type of grasshopper, they differ physiologically and in their behaviour. When environmental conditions allow, locusts multiply rapidly so that billions of them can aggregate and migrate vast distances devouring every growing green thing in their path. Plagues of locusts have occured for a long time and are even referenced in the Old Testament of the Bible. The magnitude of damage and crop loss that they can cause is enormous and beyond imagination. They have been the cause of starvation across continents in the past. The desert locust, Schistocerca gregaria (Forskål) is the most widespread and destructive of all locust species. When they invade they can cover about 30 million square kilometres and can include all or parts of 64 countries in the northwest and east of Africa, the Arabian Peninsula and central Asia, including Afghanistan, India, the Islamic Republic of Iran and Pakistan, among others.

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.

"In addition to assessing existing conditions and knowledge, the IAASTD uses a simple set of model projections to look at the future, based on knowledge from past events and existing trends such as population growth, rural/urban food and poverty dynamics, loss of agricultural land, water availability, and climate change effects. This set of volumes comprises the findings of the IAASTD. It consists of a Global Report, a brief Synthesis Report, and 5 subglobal reports. Taken as a whole, the IAASTD reports are an indispensable reference for anyone working in the field of agriculture and rural development, whether at the level of basic research, policy, or practice."--BOOK JACKET.

This book describes an array of power tools for data analysis that are based on nonparametric regression and smoothing techniques. These methods relax the linear assumption of many standard models and allow analysts to uncover structure in the data that might otherwise have been missed. While McCullagh and Nelder's Generalized Linear Models shows how to extend the usual linear methodology to cover analysis of a range of data types, Generalized Additive Models enhances this methodology even further by incorporating the flexibility of nonparametric regression. Clear prose, exercises in each chapter, and case studies enhance this popular text.

Throughout the nineteenth century, swarms of locusts regularly swept across the continent, turning noon into dusk, demolishing farm communities, and bringing trains to a halt as the crushed bodies of insects greased the rails. In 1876, the U.S. Congress declared the locust "the single greatest impediment to the settlement of the country." From the Dakotas to Texas, from California to Iowa, the swarms pushed thousands of settlers to the brink of starvation, prompting the federal government to enlist some of the greatest scientific minds of the day and thereby jumpstarting the fledgling science of entomology. Over the next few decades, the Rocky Mountain locust suddenly -- and mysteriously -- vanished. A century later, Jeffrey Lockwood set out to discover why. Unconvinced by the reigning theories, he searched for new evidence in musty books, crumbling maps, and crevassed glaciers, eventually piecing together the elusive answer: A group of early settlers unwittingly destroyed the locust's sanctuaries just as the insect was experiencing a natural population crash. Drawing on historical accounts and modern science, Locust brings to life the cultural, economic, and political forces at work in America in the late-nineteenth century, even as it solves one of the greatest ecological mysteries of our time.

Insect protein production through ‘mini-livestock farming’ has enormous potential to reduce the level of malnutrition in critical areas across the world. It has been estimated that insect eating is practised regularly by over two billion people, mostly in China and in most tropical countries in Africa, South America, and Asia. However, eating insects has been taboo in many western nations. Reasons for this are discussed in this book with examples from Finland and the UK. The enormous boom of insect farming in Finland started in September 2017 when the business type was legalized. However, a large part of the population found the insect food too expensive and exotic. UK research outlines a multitude of promising strategies to overcome ‘western’ resistance to eating insects. This book also includes a chapter on the potential of insect farming to increase global food security. It shows that Africa is a hotspot of edible insect biodiversity and there more than 500 species consumed daily. We have several examples of viable insect farming businesses that can fight poverty and malnutrition in developing countries and provide profit and wealth to rural farmers. The chapters of the book cover countries such as Cameroon, Ecuador, Finland, Ghana, India, Mexico, the UK, and the US.

This book provides stimulating and timely suggestions about expanding the world food supply to include a variety of minilivestock. It suggests a wide variety of small animals as nutritious food. These animals include arthropods (insects, earthworms, snails, frogs), and various rodents. The major advantage of minilivestock is that they do not have to be fed on grains thus saving many crop species for human consump-tion. The book suggests technologies for harvesting these small livestock.

A book of national and international importance, Fruit Fly Pests is an exhaustive compendium of information (with data provided by more than 100 contributors) that will appeal to a wide variety of readers. With huge losses experienced annually from fruit fly devastation, information on these high-profile insects is important to commercial fruit and vegetable growers, marketing exporters, government regulatory agencies, and the scientific community. Fruit flies impose a considerable resource tax, and the ones who suffer range from shippers to end users. The demand for world-wide plant protection requires up-to-date research information. This book meets that need. This book contains the proceedings from the most recent International Symposium on Fruit Flies of Economic Importance. Here you will find the major presentations given at the symposium, with an added feature - overviews from experts on topics not covered directly by participants in the symposium, filling in gaps in the current literature. The resulting publication is the most up-to-date and readable text to be found anywhere on the subject of tephritids.
