This volume presents an up-to-date account of armored scale insects (Homoptera: Diaspididas), a family of highly specialized insects, many of which are important agricultural pests. Being sedentary, colonial and rather cryptic, many species have invaded new countries with important host plants. This has made them prime targets for biological control by natural enemies.

No other book has attempted to present such a rounded picture of this important group. It covers all aspects: morphology, systematics, phylogeny, biology, ecology, natural enemies (pathogens, predators, parasites), pest...

Chromatography - A Century of Discovery 1900-2000 represents the combined thinking and contributions of many chromatographers. It includes several in-depth feature chapters covering the Beginnings of Chromatography, which highlights M.S. Tswett, the inventor of chromatography, and several other early pioneers. Included are the contributions of several Nobel Laureates, and 125 Chromatography Award Winners and contributors, an extensive bibliography of publications on the History of the Evolution of Chromatography; a presentation of Major International Symposia supporting chromatography and as...

This first part presents chapters on models of computation, complexity theory, data structures, and efficient computation in many recognized sub-disciplines of Theoretical Computer Science.

Novel asymmetric synthetic methods are a vital strategem in the armoury of the organic chemist, particularly for those involved in the preparation or application of chiral organic molecules. this series is devoted to presenting the latest advances in the field of asymmetric synthesis, drawing contributions on emerging areas and articles providing authoritative perspectives on more developed synthetic stategies from leading researchers in the field. ranging from the preparation and application of chiral cylopentadienes, the synthesis of non-racemic amines, diketones and -keto esters and...
