This book presents a broad review of the biology of grasshoppers and plague locusts, as well as katydids, crickets, mantises and other economically important orthopteroid insects. While grasshopper and locust plagues have decreased recently in North America, they continue unabated in many other parts of the world, including South America, Australia, the Middle East, Africa and western and southern Asia. Similarly, katydids attack cereals, orchards and other cultivated vegetation, and crickets damage tea, coffee and tuber crops among other plants. There have been considerable advances in our knowledge of these groups since other books addressing this subject were published. These other books have also focused on a more limited range of taxa. This book is written from a broad, comparative biological, behavioral and evolutionary approach best expressed by the neglected term bionomics. It thus covers systematics, distribution, behavior, physiology and genetics, as well as pest control and conservation. Written by authorities from the USA, Canada, UK, Spain, Israel, South Africa, India and Russia, it represents a major work for entomologists and those concerned with crop protection from pest Orthoptera.

Katydids are among the most commonly seen Australian insects. They range in size from about 5 mm to well over 90 mm and occur in many habitats all over Australia. Katydids are masters of deception, imitating twigs, bark, leaves and stems, as well as other insects. A few are brightly coloured and are distasteful to predators. They continue to be research subjects in many university curricula, where students study their behaviour, acoustical physiology and ecology. A Guide to the Katydids of Australia explores this diverse group of insects from the family Tettigoniidae, which comprises more than 1000 species in Australia, including Norfolk and Lord Howe islands. It highlights their relationships to plants, humans and the environment, and includes colour photographs of many species. 2011 Whitley Award Commendation for Field Guide.

Acridids (grasshoppers and locusts) can range from being rare curiosities to abundant menaces. Some are threatened with extinction and become subjects of intensive conservation efforts, while others are devastating pests and become the objects of massive control programmes. Even within a species, there are times when the animal is so abundant that its crushed masses cause the wheels of trains to skid (the Rocky Mountain grasshopper, Melanoplus spretus Walsh in western North America in the 1860s and I 870s), while at other times the animal is alarmingly scarce (the Rocky Mountain grasshopper went extinct in the early 1900s). Why are there these extremes in one insect family, and even in a single species? The NATO workshop examined this paradox and its implications for Environmental Security, which must address both the elements of land use (agricultural production and pest management) and conservation of biodiversity. The reconciliation of these objectives clearly demands a critical assessment of current knowledge and policies, identification of future research, and close working relationships among scientists. Insects can present two clear faces, as well as the intervening gradation. These extremes require us to respond in two ways: conservation of scarce species and suppression of abundant (harmful) species. But perhaps most important, these opposite poles also provide the opportunity for an exchange of information and insight.

Most of the 170 species of grasshoppers and crickets included in this book can be identified instantly by their songs – and often more reliably than from their appearance. Orthopterans have recently become important subjects in evolutionary biological studies and are also increasingly used in the field of conservation as indicators of undisturbed habitat. The book comprises the following chapters: Introduction; Acoustic Methods; Sound Production and Reception of European Orthoptera; The Nature and Function of the Songs; The Value of the Songs in Taxonomy and Identification; Key to the singing Orthoptera of Western Europe, based primarily on their Songs; and other Animal Sounds that could be confused with Orthoptera Songs – illustrated with over 1600 oscillograms; three Appendixes (Check-list of the species included; Summary of Nomenclatural Changes; Data for the Song Recordings); Glossary; References; Index to Vernacular Names; and General Index.

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.
