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
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 photographic guide to 536 species of plant galls found west of the Rockies Beautiful and bizarre, plant galls are growths of various shapes, sizes, and colors produced in response to invading organisms. Describing 536 species of galls and their causative agents, Plant Galls of the Western United States explores this unique realm with stunning photos and fascinating information about the life cycles of the organisms involved. Often species-specific, plant galls can be shaped like stars, baskets, clubs, wigs, bowls, and cups, with colors and combinations that stagger the imagination. This richly illustrated field guide examines how galls develop, and their uses, seasonal appearance and growth rate, predators, and defense mechanisms. The “architects” of galls—bacteria, fungi, mites, moths, beetles, flies, midges, and wasps—are explored in depth, and descriptions are paired with illustrations of these gall-inducing organisms and their typical galls. Gall accounts are divided into those that occur on trees, shrubs, and miscellaneous hosts, including native and ornamental plants. The guide contains a useful glossary and a bibliography. Features 536 gall species—including 120 new to science and 232 that have never appeared in a field guide before Examines for the first time more than 90 species from southwestern oak trees Contains more than 150 species from most of the deserts of the western states

Book Description
Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Book Description
Medical and Veterinary Entomology, Second Edition, has been fully updated and revised to provide the latest information on developments in entomology relating to public health and veterinary importance. Each chapter is structured with the student in mind, organized by the major headings of Taxonomy, Morphology, Life History, Behavior and Ecology, Public Health and Veterinary Importance, and Prevention and Control. This second edition includes separate chapters devoted to each of the taxonomic groups of insects and arachnids of medical or veterinary concern, including spiders, scorpions, mites, and ticks. Internationally recognized editors Mullen and Durden include extensive coverage of both medical and veterinary entomological importance. This book is designed for teaching and research faculty in medical and veterinary schools that provide a course in vector borne diseases and medical entomology; parasitologists, entomologists, and government scientists responsible for oversight and monitoring of insect vector borne diseases; and medical and veterinary school libraries and libraries at institutions with strong programs in entomology. Follows in the tradition of Herm's Medical and Veterinary Entomology The latest information on developments in entomology relating to public health and veterinary importance Two separate indexes for enhanced searchability: Taxonomic and Subject New to this edition: Three new chapters Morphological Adaptations of Parasitic Arthropods Forensic Entomology Molecular Tools in Medical and Veterinary Entomology 1700 word glossary Appendix of Arthropod-Related Viruses of Medical-Veterinary Importance Numerous new full-color images, illustrations and maps throughout
