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.

The papers in this book are organized as follows: insect-plant communities, host-plant selection, genetics and evolution, host-plant resistance and application of transgenic plants, and multitrophic interactions. Besides seven invited papers and a paper with concluding remarks, this volume also contains the short communications of all 115 oral presentations and posters. Included too, are the summaries of four European Science Foundation workshops held over the past two years, where European scientists discussed the state-of-the-art and the future of major topics in insect-plant interactions in order to develop better integrated research programs. The field of insect-plant interactions nowadays includes almost all of biology, as well as parts of chemistry and physics. It takes a central position in biology because insects are the most abundant animal group, half of them are herbivores and they dominate all terrestrial ecosystems. Knowledge of insect-plant interactions is thus fundamental to an understanding of the evolution of life on Earth. Two major topics of worldwide concern give this field an extra dimension. First, large amounts of food crops are still lost due to insect pests. With the increasing concern for environmental pollution and the subsequent plans to drastically reduce pesticides, integrated pest management and development of resistant crops become a major focus in agriculture. The importance of the study of insect-plant relationships is thus continuously augmented. Clearly, successful pest control demands sufficient fundamental knowledge of pest-host interactions. Second, such work can contribute towards stopping or even counterbalancing the threatening biodiversity crisis thanks to an understanding of how the interaction of insects and plants has influenced and still influences the diversification and speciation (evolution) of both groups. These problems should, of course, be approached at a multitrophic level.

Our objective in compiling a series of chapters on the chemical ecology of insects has been to delineate the major concepts of this discipline. The fine line between presenting a few topics in great detail or many topics in veneer has been carefully drawn, such that the book contains sufficient diversity to cover the field and a few topics in some depth. After the reader has penetrated the crust of what has been learned about chemical ecology of insects, the deficiencies in our understanding of this field should become evident. These deficiencies, to which no chapter topic is immune, indicate the youthful state of chemical ecology and the need for further investigations, especially those with potential for integrating elements that are presently isolated from each other. At the outset of this volume it becomes evident that, although we are beginning to decipher how receptor cells work, virtually nothing is known of how sensory information is coded to become relevant to the insect and to control the behavior of the insect. This problem is exacerbated by the state of our knowledge of how chemicals are distributed in nature, especially in complex habitats. And finally, we have been unable to understand the significance of orientation pathways of insects, in part because of the two previous problems: orientation seems to depend on patterns of distri bution of chemicals, the coding of these patterns by the central nervous system, and the generation of motor output based on the resulting motor commands.
