One of the world's most insightful writers on the subject brings together an array of important and readable information on the ways in which insects and plants coexist in nature. Interrelationship Between Insects and Plants is a rare and expansive look at the intertwining of these two vastly different species. Its aim is to summarize in a simple and understandable way the basis of food selection among insects, and to review the various sides of their relationships with plants.

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.

Botanists and zoologists have recognized for centuries the specificity of various insects for plants, and entomolo gists have long been aware that insects defend themselves from predators by emitting repulsive odors. Only recently have chemists and biologists established a joint endeavor for studying the chemical relationships between plants and insects. The present symposium volume of the Phytochemical Society of North America's RECENT ADVANCES IN PHYTOCHEMISTRY consists of eight papers dealing with phytochemical relation ships between plants and their insect herbivores. The fifteenth P.S.N.A. annual symposium and meeting was held in August, 1975, on the campus of The University of South Florida, Tampa. The chemical defenses of apparent and unapparent plants were contrasted by Feeny. Rodreguiz and Levin illustrated parallel defense mechanisms of plants and insects and then Hendry, Kostelc, Hindenlang, Wichmann, Fix and Koreniowski discussed chemical messengers for both plants and insects. Subsequently Beck and Reese reviewed plant contributions to insect nutrition and metabolism. Indepth studies for the monarch butterfly-milkweed interaction were presented by Roeske, Seiber, Brower, and Moffitt and for the cotton boll weevil-cotton plant relationship by Hedin, Thompson, and Gueldner. In the latter portion of the symposium Rhoades and Cates presented a general theory concerning the coevolu tion of insects and plant antiherbivore chemistry.

Insects have evolved very unique and interesting tactics using chemical signals to survive. Chemical ecology illustrates the working of the biological network by means of chemical analyses. Recent advances in analytical technology have opened the way to a better understanding of the more complicated and abyssal interactions of insects with other organisms including plants and microbes. This book covers recent research on insects and chemical communications and presents the current status about challenges faced by chemical ecologists for the management of pests in agriculture and human health.

For more than 20 years insect/plant relations have been a focus for studies in ecology and evolution. The importance of insects as crop pests, and the great potential of insects for the biological control of weeds, have provided further impetus for work in this area. All this attention has resulted in books on various aspects of the topic, and reviews and research papers are abundant. So why write another book? It seems to us that, in the midst of all this activity, behavior has been neglected. We do not mean to suggest that there have not been admirable papers on behavior. The fact that we can write this book attests to that. But we feel that, too often, behavior is relegated to a back seat. In comparison to the major ecological and evolutionary questions, it may seem trivial. Yet the whole process of host-plant selection and host-plant specificity amongst insects depends on behavior, and selection for behavioral differences must be a prime factor in the evolution of host-plant specificity. In writing this book, we hope to draw attention to this central role of behavior and, hopefully, encourage a few students to attack some of the very difficult questions that remain unanswered.

This book explains the natural chemical compounds that determine the fascinating interactions between plants and insects providing a gentle and absorbing introduction to organic chemistry.
