Book Description
This book has been produced with the aim of stimulating the general naturalist to take a closer look at the bumps and lumps that make up the fascinating world of plant galls. Induced by a variety of insects and other organisms and ranging from tiny pimples to bizarre and often very attractive and exquisitely sculptured growths, plant galls are mystery to many people, but they offer a fascinating field of study for both botanists and zoologists. Galls can be found on a very wide range of both woody and herbaceous plants, with over 50 different kinds occurring on Britain's oak trees alone, and there is still much to be learned about even the commonest examples. An introduction to the nature of plant galls and their formation Brief descriptions of some of the organisms that cause or induce galls Superb photographs of just over 200 of the commonest or most conspicuous of Britain's 1,000 or so plant galls, arranged according to their host plants to aid field identification Descriptions of these galls and the life histories of the organisms that cause them

Book Description
A much-needed new study on plant galls growths on plants formed of plant tissue that are caused by other organisms. Most naturalists have come across oak apples, robin s pincushions, marble galls and witches brooms, a few of the more familiar examples of the strange growths that are plant galls. They are beautiful, often bizarre and colourful, and amazingly diverse in structure and in the organisms which cause them. They have been known since ancient times and have attracted superstitions and folk customs. Both the ancient Greeks and the Chinese used them in herbal medicine, and until well into the nineteenth century, they had a variety of commercial uses: important for dyeing cloth, tanning leather and for making ink. Knowledge of gall types increased during the late nineteenth century and throughout the twentieth century as more species were described and their structure became more clearly understood, and yet even today, little is known about the mechanisms that cause gall formation as well as the life cycles of the organisms that initiate gall growth. Since most galls do not cause any economic damage to crop plants, research funding has traditionally been sparse in this area. However, the insect cycles and gall structures are amazing examples of the complexity of nature. Margaret Redfern explores these fascinating complexities in this latest New Naturalist volume, providing much-needed insight into the variety of galls of different types caused by a wide range of organisms including fungi, insects and mites. She discusses the ecology of galls more generally and focuses on communities of organisms within galls, the evolution and distribution of galls, as well as human and historical perspectives."

Book Description
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.

Book Description
Ornamental trees, shrubs and flowers have always been extremely popular and in large demand. Whether in gardens or parks, common usage of alpines, bedding plants, cacti, cut flowers, house plants and pot plants, as well as herbaceous plants, ornamental grasses, shrubs and trees makes a definitive volume on their pests of essential value to entomologists and plant scientists. The fully revised and updated second edition of Pests of Ornamental Trees, Shrubs and Flowers follows up the successful previous edition with coverage of many new pests and highly detailed color photographs. The book opens with a review of the main features of insects, mites and other major pest groups. . Each major order and family of pests is considered in turn, with details of their status, host range, world distribution, diagnostic features and biology. Descriptions of the characteristic damage caused are also given. Contains coverage of more than 60 new pests and nearly 90 additional color photographs Discusses principles of pest control of ornamental plants, followed by sections on the various pests
