Book Description
Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

Book Description
Here are over 1,000 pages of authoritative information on the archaeology of Greek and Roman civilization. The sites discussed in the more than 2,800 entries are scattered from Britain to India and from the shores of the Black Sea to the coast of North Africa and up the Nile. They are located on sixteen area maps, keyed to the entries. The entries were written by 375 scholars from sixteen nations, many of whom have worked at the sites they describe. Until now our knowledge of the Classical period has been scattered in hundreds of sources dating from antiquity to our own times. This volume provides essential information on work accomplished, in progress, and still to be undertaken. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
"According to one myth, the first Athenian citizen was born from the earth after the sperm of a rejected lover, the god Hephaistos, dripped off the virgin goddess Athena's leg and onto fertile soil. Henceforth Athenian citizens could claim to be truly indigenous to their city and to have divine origins that bypassed maternity. In these essays, the renowned French Hellenist Nicole Loraux examines the implication of this and other Greek origin myths as she explores how Athenians in the fifth century forged and maintained a collective identity."--Publisher's description.

Book Description
In Greco-Roman society the typical labourer was a peasant, not a slave. Yet, while specialized studies of ancient slavery abound, the subject of free labour, its incidence, status and economic significance, has received little attention. This volume of essays provides a summary of the available evidence for non-slave labour in antiquity and a bibliographical guide, but in addition advances novel interpretations concerning, for example, the composition of the 'labouring class', the relation between slave and peasant systems of production, and the importance of free dependent labour in the Western Roman provinces.
