Microbial Mediation of Plant-Herbivore Interactions

Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah K. Letourneau Focusing on three trophic levels, this study widens the current understanding of the ecological interactions between plants, herbivores, and their parasitoids and predators. Emphasized are the mediating effects of plant-derived allelochemicals on those interactions. The book also covers microorganisms as mediators of intertrophic and intratrophic interactions; theory and mechanisms: plant effects via allelochemicals on the third trophic level; and key roles of plant allelochemicals in survival strategies of herbivores. 1988 (0 471-83276-6) 362 pp. Plant-Animal Interactions Evolutionary Ecology in Tropical and Temperate Regions Edited by Peter W. Price, Thomas M. Lewinsohn, G. Wilson Fernandes and Woodruff W. Benson An outgrowth of an international symposium on Evolutionary Ecology of Tropical Herbivores held at UNICAMP, Brazil, this unique collaborative effort from leading scientists worldwide is the first comparative analysis of the existing ecological systems of temperate and tropical regions. In-depth and timely, the book's manifold analyses includes a discussion of tropical and temperate comparisons; mutualistic relationships between plants and animals; antagonistic relationships between plants and animals; plant-butterfly interactions; specificity in plant utilization; and community patterns in natural and agricultural systems. Amply illustrated with 150 detailed graphics, the book provides a fascinating visual tour of the flora and fauna described. 1991 (0 471-50937-X) 639 pp. Integrated Pest Management Systems and Cotton Production Edited by Raymond E. Frisbie, Kamal M. El-Zik and L. Ted Wilson This work sheds light on the link between the thriving U.S. cotton crop and integrated pest management. It offers a unique theoretical and conceptual framework for studying the cotton-IPM system. Other relevant issues such as the development and use of pest models, quantitative sampling principles in cotton IPM, economic injury levels and thresholds for cotton pests, and strategies and tactics for managing weeds, plant pathogens, nematodes, and insects are also described. Covering every facet of IPM technology, this is a significant contribution to the literature of pest management. 1989 (0 471-81782-1) 437 pp. Partial table of contents:

The mediating influence of microbes in the interplay of plants and herbivores has only recently begun to hold the interest of scientists. Not only is the microbial universe one of immense intricacy, it is one that has large implications for the ultimate welfare of the planet’s ecosystems. Microbial Mediation of Plant-Herbivore Interactions illustrates just how widespread is the mediation of plant-herbivore interactions by microbes and the diverse and significant impacts microbes have on plant-herbivore relationships. Not simply a compendium of microbial mediation, this landmark work provides, instead, a general framework which sheds light on the diversity of microbial effects on plant-herbivore relationships. Using a functional, mechanistic approach, as opposed to a descriptive, taxonomic approach, the text provides a key to understanding the net effects of microbes on plant resource suitability and herbivore utilization. This net effects approach provides a window onto the underlying mechanisms that account for patterns of interaction between microbes, plants, and herbivores. Part I, Interactions Among Insects, Plants and Microorganisms, provides an integrated framework for understanding microbial mediation. Part II, Plant Mutualists, examines many of the diverse interactions between nitrogen fixers, ectomycorrhizal fungi, or fungal endophytes, with various above- and below-ground herbivores. Part III, Plant Pathogens, discusses how plant pathogens alter plant resource suitability to insect herbivores as well as the implications of plant pathogens that are carried by insect herbivores and pathogenic to the insect. Part IV, Insect Mutualists, examines microbial effects on herbivore utilization. Part V, Insect Pathogens, discusses the interactions between plant chemicals and insect pathogens in terms of their effects on the herbivore. Chapters are grouped within parts on the basis of the primary organism with which the microbes are directly, functionally associated. Each part is prefaced by a net effects diagram and an introduction which summarizes key findings and relates them to the major themes of the text.
