Both volumes of Parasites and Pathogens of Insects provide in-depth coverage of the interface between insect parasites and pathogens and hosts, and explore the relationships between these partners. They emphasize biochemical and molecular interactions, basic biology, and the roles of hormones, receptors, and other cellular components in modulating interactions between host insects and attacking agents. These topics also are assessed in relation to biotechnology and biological control. In the short term, these volumes fill a void in current literature by emphasizing basic interactions at the biochemical and molecular levels. In the long term, these interactions may provide avenues for exploitation to enhance the rate of "beneficial" parasitism or to reduce the rates of disease transmission and infection of vertebrate hosts. Presents the latest information on insect parasites and pathogens Describes biochemical and molecular host-parasite and host-pathogen relationships Covers mechanisms of insect pathogenicity and resistance Provides exceptional breadth of coverage and authoritative reviews Special topics Transposable elements in insect pathogens Co-evolution and gene transfer between hosts and invaders Biological control

This volume contains the invited lectures presented in a symposium entitled "Evolutionary strategies of parasitic insects and mites" at the national meeting of the Entomological Society of America in Minneapolis, Minnesota, 2-5 December, 1974. The intent was to bring together biologists who have worked on arthropods that are either plant or animal parasites in order to foster consideration of general aspects of the parasitic way of life. There seems to be a deficiency of ecological and evolutionary concepts relating to parasitism, in contrast to the burgeoning literature on predation, and it appeared that an amalgamation of studies on plant and animal parasites might help development of some generalities. Since parasities are far more numerous than predators in the world fauna, or in any particular community, emphasis on their study is justified. I freely admit that para sitoids have been usefully regarded as predators by ecologists, and many concepts on predation have been derived from their study. Also, in whichever category one places the parasitoids, that is the one which contains the most species. However, from an evolu tionary point of view they show many characteristics that must be regarded as those of a parasite. Notably, they are small, highly specific to their host, highly coevolved with it, as a result many species can coexist, and their adaptive radiation has produced the majority of the species diversity seen on Earth today.

WASPS is the first full-color, illustrated guide featuring approximately 150 species of flower-visiting wasps that occur in eastern North America, and the specific native plants and habitat each species depends upon. Written with an ecological lens, this richly-illustrated book details wasp diversity and has full-page profiles for each wasp species that include identification tips, geographic range maps, biology, prey, natural history and habitat. Five introductory chapters cover wasp taxonomy, nesting biology, prey-hunting behaviors, diet, anatomy, as well as wasp habitat enhancement and management, and the ecosystem services provided by wasps-insect pest population control and pollination. Profiles of each wasp species comprise the major part of the book and are organized by family, showcasing twelve families and sixty-eight wasp genera. Also included are eastern North American regional native plant guides, tips on wasp observation, and over 1000 stunning photographs. This is an essential book for conservationists, naturalists, insect enthusiasts, biologists, nature photographers, native plant aficionados, and anyone interested in beneficial insects and pollinators.

This book analyzes for the first time how parasites shape the biology of social insects: the ants, wasps, bees, and termites. Paul Schmid-Hempel provides an overview of the existing knowledge of parasites in social insects. Current ideas are evaluated using a broad database, and the role of parasites for the evolution and maintenance of the social organization and biology of insects is carefully scrutinized. In addition, the author develops new insights, especially in his examination of the intricate relationships between parasites and their social hosts through the rigorous use of evolutionary and ecological concepts. Schmid-Hempel identifies gaps in our knowledge about parasites in social insects and uses models to develop new questions for future research. In addition, issues that are usually considered separately--such as division of labor, genetics, immunology, and epidemiology--are placed in a common framework to analyze two of the most successful adaptations of life: parasitism and sociality. This work will appeal not only to practitioners in the fields of behavioral ecology and sociobiology, but also to others interested in host-parasite relationships or in social organisms, such as apiculturists struggling to overcome the problems arising from mite infestations of honeybee colonies.

Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i
