A comprehensive treatise on thrips as crop pests set against a background covering basic biology, ecology, applied science and pest control.

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.

This text provides a scientific introduction to termites, including their behaviour, pest status and control.

Thrips remain a mysterious group of insects because up to now they have been studied by only a few specialists. A factor limiting their appeal has been the problem of identification. Some species are genuinely difficult to separate, but others can be named fairly easily and some can even be recognised alive in the field. The keys in this book have been designed to enable anyone with access to a good microscope to overcome the taxonomic hurdle in order to explore the unusual natural history and behaviour of thrips.

For several decades, Arabidopsis thaliana has been the organism of choice in the laboratories of many plant geneticists, physiologists, developmental biologists, and biochemists around the world. During this time, a huge amount of knowledge has been acquired on the biology of this plant species, which has resulted in the development of molecular tools that account for much more efficient research. The significance that Arabidopsis would attain in biological research may have been difficult to foresee in the 1980s, when its use in the laboratory started. In the meantime, it has become the model plant organism, much the same way as Drosophila, Caenorhabditis, or mouse have for animal systems. Today, it is difficult to envision research at the cutting edge of plant biology without the use of Arabidopsis. Since the first edition of Arabidopsis Protocols appeared, new developments have fostered an impressive advance in plant biology that prompted us to prepare Arabidopsis Protocols, Second Edition. Completion of the Arabidopsis genome sequence offered for the first time the opportunity to have in hand all of the genetic information required for studying plant function. In addition, the development of whole systems approaches that allow global analysis of gene expression and protein and metabolite dynamics has encouraged scientists to explore new scenarios that are extending the limits of our knowledge.

Darwin famously described special difficulties in explaining social evolution in insects. More than a century later, the evolution of sociality - defined broadly as cooperative group living - remains one of the most intriguing problems in biology. Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species, from ants to primates, highlighting key natural and life history data and providing a comparative view across animal societies. In establishing a single framework for a common, trait-based approach towards social synthesis, this volume will enable graduate students and investigators new to the field to systematically compare taxonomic groups and reinvigorate comparative approaches to studying animal social evolution.
