The 11th International Symposium on Insect-Plant Relationships (SIP11), held on August 4-10, 2001, in Helsingør, Denmark, followed the tradition of previous SIP meetings and covered topics of different levels from chemistry, physiology, and ethology to ecology, genetics, and evolution of insect-plant relationships. The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms.

Evidence has been mounting for some time that intensive row-crop agriculture as practiced in developed countries may not be environmentally sustainable, with concerns increasingly being raised about climate change, implications for water quantity and quality, and soil degradation. This volume synthesizes two decades of research on the sustainability of temperate, row-crop ecosystems of the Midwestern United States. The overarching hypothesis guiding this work has been that more biologically based management practices could greatly reduce negative impacts while maintaining sufficient productivity to meet demands for food, fiber and fuel, but that roadblocks to their adoption persist because we lack a comprehensive understanding of their benefits and drawbacks. The research behind this book, based at the Kellogg Biological Station (Michigan State University) and conducted under the aegis of the Long-term Ecological Research network, is structured on a foundation of large-scale field experiments that explore alternatives to conventional, chemical-intensive agriculture. Studies have explored the biophysical underpinnings of crop productivity, the interactions of crop ecosystems with the hydrology and biodiversity of the broader landscapes in which they lie, farmers' views about alternative practices, economic valuation of ecosystem services, and global impacts such as greenhouse gas exchanges with the atmosphere. In contrast to most research projects, the long-term design of this research enables identification of slow or delayed processes of change in response to management regimes, and allows examination of responses across a broader range of climatic variability. This volume synthesizes this comprehensive inquiry into the ecology of alternative cropping systems, identifying future steps needed on the path to sustainability.

Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.

In 1984, a new research working party on mechanismsofwoody plant resistance against insects and pathogens(lUFROS2. 05-06) was formed in the International Union ofForestryResearchOrganizations. Thepurposeofthisworkingparty istostimulate and facilitate research progress in this areathroughenhancedcommunication among themany researchscientistsscatteredamongthevariouscountriesoftheworld. This volume istheresultofthe first internationalsymposiumofthisworkingparty, which took place in Orleans. France on August 26-29, 1986. Thanks are due to Institute Nationalde laRechercheAgronomique, StationdeZoologie, Forestiere, fortheir in- strumental part in organizingthis symposium, and to the University and the Cityof Orleansforgenerousfinancial support. The intentofthis proceedings is to (a) bring together adiverse array ofresearch resultsonthemechanismsofwoodyplantresistanceagainstdifferentkindsofinsects. and(b) to search for threadsofcommonality among these different plant/insect as- sociationstofurtherourfundamental understandingofhowplantsdefendthemselves againstphytophagousorganisms.

Over the past 40 years, the SIP meetings have played a central role in the development of the field of insect-plant relationships, providing both a show-case for current research as well as a forum for the airing and development of influential new ideas. The 10th symposium, held 4-10 July 1998, in Oxford, followed that tradition. The present volume includes a representative selection of fully refereed papers from the meeting, plus a listing of the titles of all presentations. The volume includes reviews of major areas within the subject, along with detailed experimental studies. Topics covered include central neural and chemosensory bases of host plant recognition, integrative studies of insect behaviour, tritrophic interactions, plant defences, insect life histories, plant growth responses, microbial partners in insect-plant associations, and genetic bases of host plant associations. The book provides a key source for students and research workers in the field of insect-plant relationships.

Plant volatiles—compounds emitted from plant organs to interact with the surrounding environment—play essential roles in attracting pollinators and defending against herbivores and pathogenes, plant-plant signaling, and abiotic stress responses. Biology of Plant Volatiles, with contributions from leading international groups of distinguished scientists in the field, explores the major aspects of plant scent biology. Responding to new developments in the detection of the complex compound structures of volatiles, this book details the composition and biosynthesis of plant volatiles and their mode of emission. It explains the function and significance of volatiles for plants as well as insects and microbes whose interactions with plants are affected by these compounds. The content also explores the biotechnological and commercial potential for the manipulation of plant volatiles. Features: Combines widely scattered literature in a single volume for the first time, covering all important aspects of plant volatiles, from their chemical structures to their biosynthesis to their roles in the interactions of plants with their biotic and abiotic environment Takes an interdisciplinary approach, providing multilevel analysis from chemistry and genes to enzymology, cell biology, organismal biology and ecology Includes up-to-date methodologies in plant scent biology research, from molecular biology and enzymology to functional genomics This book will be a touchstone for future research on the many applications of plant volatiles and is aimed at plant biologists, entomologists, evolutionary biologists and researchers in the horticulture and perfume industries.

Throughout the world there is a need to control forest insect pests. This text focuses predominantly on insect pests, but many examples relate to fungal pathogens, saome of which are vectored by forest insects. It looks at the development of Integrated Pest Management (IPM).
