Plant galls may be produced by a wide variety of organisms, from fungi to parasitic insects, on an equally wide variety of hosts. Their taxonomy is highly complex, as are the life cycles of the organisms associated with them. Yet, common as they are, plant galls are often poorly understood. This book brings together information from the diverse disciplines involved in the study of plant galls: ecology, evolution, molecular biology, physiology, and developmental biology. The work considers the latest issues, covering questions of classification, coevolution, ecology, physiology, and plant genetic engineering. As an up-to-date resource in an area of immense interest and debate, the book will enhance the quality of discussion surrounding these phenomena, across all disciplinary perspectives.

The Encyclopedia of Insects is a comprehensive work devoted to all aspects of insects, including their anatomy, physiology, evolution, behavior, reproduction, ecology, and disease, as well as issues of exploitation, conservation, and management. Articles provide definitive facts about all insects from aphids, beetles and butterflies to weevils and yellowjackets. Insects are beautiful and dreadful, ravenous pests and devastating disease vectors, resilient and resistant to eradication, and the source of great benefit and great loss for civilization. Important for ecosystem health, they have influenced the evolution of other life forms on our planet including humans. Anyone interested in insects, from university professors and researchers to high school students preparing a report, will find The Encyclopedia of Insects an indispensable volume for insect information.* An unprecedented collection in 1,276 pages covering every important aspect of insects * Presents 270 original articles, thoroughly peer reviewed and edited for consistency * Features 1,000 figures and tables, including 500 full-color photographs* Includes the latest information contributed by 250 experts in 17 countries * Designed to save research time with a full glossary, 1,700 cross-references, and 3,000 bibliographic entries

Plants, Chemicals and Growth focuses on chemicals that regulate the growth and development of plants. It explores the problems of growth and growth regulation by looking at the roles of chemical substances, natural and synthetic, which affect the behavior of the cells of flowering plants. It also describes the variety of responses triggered by such chemicals, which include herbicides, those that stimulate the rooting of cuttings or cause leaf or fruit abscission, and those associated with fruit setting and artificial parthenocarpy. Comprised of 10 chapters, this volume begins with an overview of examples of chemical regulators and the biological responses they induce in plants, from tropism and chemotropism to nastic responses; rhythmic phenomena in growth and development; initiation of lateral organs and problems of phyllotaxy; periodicities in growth; and effects on the balance between vegetative growth, flowering, and fruiting. It discusses the totipotency and exogenous regulation of cells, history and modern concepts of plant growth regulators, the ways chemicals induce growth in quiescent cells, and growth-regulating effects in free cell systems. The reader is also introduced to biologically active compounds, such as indolyl and triazine compounds; how plant-regulating substances work; concepts and interpretations of plant growth regulation; and problems and prospects of chemical regulation of plant growth and development. This book will be of interest to teachers, biology students, agriculturalists, and researchers.

Perspectives in Urban Entomology is a collection of papers presented at the "Ecology and Management of Insect Populations in Urban Environments" held in Washington, D.C. in 1976. This collection deals with urban entomology with emphasis on insects, insect-plant relationships, and arthropods in the urban environments. One paper examines the causes why certain species manage to survive in an urban environment while others do not. The book cites one example—the Rothamsted insect survey—and analyzes the pressures of development in the surrounding land area. One paper addresses the educational and esthetic value of an insect-plant relationship in an ever expanding development of urban spaces. Another paper shows the value and benefit of a scientific investment in urban agriculture—defined as small-scale agriculture in urban areas—as contributing to food crops. Some papers also examine the use of insecticides and technology transfer in the management of urban pest control. This book will be valuable for entomologists, urban planners and developers, environmentalists, and for general readers residing in metropolitan areas.

Plants, Chemicals and Growth investigates natural and synthetic chemicals that control plant growth and development. It examines how plant growth regulators, such as 2,4-D, 2,4-dichlorophenoxyacetic acid, 2,4,5-T, 2,4,5-trichlorophenoxyacetic acid, ammonium sulfamate, indole-3-butyric acid, disodium 3,6-endoxohexahydrophthalate, gibberellic acid, and 2-chloroethyltrimethylammonium chloride, induce biological responses in plants. These responses range from tropism and chemotropism to growth of organs by cell division and enlargement, rhythmic phenomena in growth and development, initiation of lateral organs and problems of phyllotaxy, and the regulatory effects of light and temperature on growth and form. Comprised of 10 chapters, this volume begins with an overview of chemical regulators and the ways in which they elicit biological responses in plants; how chemical regulation of plants is related to the growth and development of flowering plants; cell growth and cell division; cell cycle; and cellular ontogeny. It then looks at the history and modern concepts of growth-regulating compounds, such as auxins, cytokinins, and gibberellins. The book introduces readers to how chemicals induce growth in quiescent cells; natural sources of growth stimulatory substances; synergisms and interactions of growth regulatory systems; growth-regulating effects in free cell systems; examples of biologically active compounds; the mechanisms of action of plant growth regulators; concepts and interpretations of plant growth regulation; and prospects and problems associated with chemical regulation of plant growth and behavior. Teachers, biology students, agriculturalists, and researchers will find this book extremely useful.
