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.

Chemical warfare between plants and their herbivores and pathogens was first brought to our attention by the publication 25 years ago of the paper by Fraenkel in Science. There, he pointed out that most plants have similar nutritional characteristics so that the selection of plants by insect herbivores must depend on the relative toxicity of secondary compounds. This led, rather gradually, to a host of papers on plant-herbivore interactions. More or less at the same time, insect physiologists and ecologists were starting to realise the importance of chemical communi cation systems in determining sexual and other characteristics of insect behaviour. Nine years ago the Phytochemical Society of North America published their Symposium on 'Biochemical Interaction Between Plants and Insects' in which the plant apparency theory was expounded by both Paul Feeny and Rex Cates and David Rhoades. This stated that plants which are apparent usually contain secondary components which reduce digestibility (tannins and lignins) while ephemeral plants have more toxic, and perhaps less costly, compounds such as alkaloids. These papers stimulated much research on biochemical ecology. The recognition of the importance of the biochemical factors in such interactions is not just of scientific interest. It is vitally important in programs for the production of new varieties of cultivated plants, especially in tropical countries where about one-third or more of the crops are lost to predation or disease.
This latest volume in Wiley Blackwell’s prestigious Annual Plant Reviews brings together articles that describe the biochemical, genetic, and ecological aspects of plant interactions with insect herbivores.. The biochemistry section of this outstanding volume includes reviews highlighting significant findings in the area of plant signalling cascades, recognition of herbivore-associated molecular patterns, sequestration of plant defensive metabolites and perception of plant semiochemicals by insects. Chapters in the genetics section are focused on genetic mapping of herbivore resistance traits and the analysis of transcriptional responses in both plants and insects. The ecology section includes chapters that describe plant-insect interactions at a higher level, including multitrophic interactions, investigations of the cost-benefit paradigm and the altitudinal niche-breadth hypothesis, and a re-evaluation of co-evolution in the light of recent molecular research. Written by many of the world’s leading researchers in these subjects, and edited by Claudia Voelckel and Georg Jander, this volume is designed for students and researchers with some background in plant molecular biology or ecology, who would like to learn more about recent advances or obtain a more in-depth understanding of this field. This volume will also be of great use and interest to a wide range of plant scientists and entomologists and is an essential purchase for universities and research establishments where biological sciences are studied and taught.

Biochemical interaction between plants and insects discusses about biochemical interaction between plants and insects in a simple yet detailed manner. This book comprises topics such as beneficial insect to plants, the importance of insects in plants pollination process, harmful insect pests of the plants and insect pests that attack specific food crop plants. This book basically explains how plants and insects intervene in a detailed way. Different common beneficial insects are also discussed. Insect and pests that attack specific cash crops, biological association between root-knot nematode species and tubers, process of insects locating their host plants, plant species and their essential oils on some storage insect and pests, impacts of climate change on biological and ecological interaction between insects and plants are some of the topics which are also discussed in this book.
Presents the first efforts to explore ecological interactions between insects and plants across several trophic levels, with special focus on mediation of complex interactions by plant allelochemicals. First section looks at effects of plant allelochemicals on predator-prey and host-parasitoid interactions. Second section reveals the role of microorganisms as mediators of interactions between insects and plants. Third section unifies and extends current theory to examine the effects of allelochemicals on the second and third trophic levels. Final section traces the physiological effects of plant allelochemicals in animal behavior, population regulation, maintenance of mimicry systems, and evolution of host range.
