Herbivorous Insects: Host-Seeking Behavior and Mechanisms addresses mechanisms of searching behavior leading ultimately to host location of herbivorous insects. It is divided into four sections, wherein the first two sections deal with neurophysiology and the diversity of behavioral induction cues. The third section covers the searching mechanisms as affected by insects' breadth of diet. The last part examines the evolutionary analysis of the behavioral and physiological adaptations in insect/host plant relations. This book starts with an introduction to the chemical sensory system as it relates to host selection in general. This is followed by considerable discussions on host-seeking behavior and allied patterns in behavior. This text also includes the study of oviposition behavior in butterflies belonging to Papilionidae. The third section presents host selection and colonization by three insects within the saprophage-predator continuum, namely, Hylurgopinus rufipes, Scolytus multistriatus, and Pissodes strobi. The behaviors by which certain oligophagous insects locate and select food plants are also considered. The concluding part addresses the unifying theme and the diversity of responses of phytophagous insects to plants. The book provides direction toward developing a unifying theme and improving the ability to unravel the complexities of insect/plant interactions. Behaviorists, ecologists, entomologists, evolutionary biologists, and physiologists will find this book invaluable.

Insect Chemical Ecology provides a comprehensive view of how natural selection acts upon interacting organisms and how particular physical and biological properties of chemical compounds act as constraints upon which natural selection may act. Individual chapters raise specific questions as to the nature of these interactions. The first part contains reviews on antagonistic and mutualistic chemical interactions, the `raw materials' of chemical evolution, the economics of offensive and defensive chemicals, and neurobiology. The second part discusses particular problems such as the evolution of resistance, insect pollination, learning, pheromones, sequestration of semiochemicals, the role of microorganisms, sex attractants, the evolution of host races and biotypes, and the role of semiochemicals and the evolution of sociality of insects. The last chapter discusses the role of chemical-based pest management programs in an ecological and evolutionary framework.

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.

In the study of the physiological basis of animal behavior Vince Dethier has been a pioneer, a guiding star. Although his own work has centered on the blowfly and the caterpillar, his interests and influence have spread far beyond the insects. The breadth of this impact is indicated by the contributions from colleagues and former students in this volume. These papers were originally presented at a meeting to honor Vince's 70th birthday held at the University of Massachusetts, Amherst, in May 1985. It was attended by friends and col leagues of all ages from many parts of the world. However, the picture presented by these papers is not the whole story. What it does not show is the extent of Vince's interest and influence beyond the rigorous, though friendly, atmosphere of the research laboratory. His idyllic summers in Maine have produced studies on the natural history of feeding by insects culminating in The Tent Makers, with more to come. In these studies we see his real love and, dare we say, understanding of the insect. Vince Dethier is not concerned simply with reaching the established scientist. In To Know a Fly he reaches out to those just beginning, perhaps even to those who will never begin, and provides insight both to the experimentalist's approach and to the fun of research. His sense of fun and his elegant, fluent writing have given us, too, his tongue-in-cheek fictional writings for children of all ages.

The authoritative overviews in this volume provide a wealth of practical information on current approaches to the study of insect-plant interactions. Methods described include direct behavioral observation; assays of host finding, oviposition, and feeding behavior of insect herbivores; post-ingestion physiological effects; measurement of food quality and sensory responses of insects to plant stimuli; chemical isolation and identification of active phytochemicals; evaluation of plant resistance to insects; and the biochemistry of allelochemic interactions.

Insect-Plant Interactions is a series devoted to reviews across the breadth of the topic from cellular mechanisms to ecology and evolution. Articles are selected from areas of particular current interest or subjects that would especially benefit from a new review. It is hoped that the interdisciplinary selection in each volume will help readers to enter new fields of insect-plant interactions. Volume II contains six very different articles.

During the past two decades a wealth of information has been developed from research on the chemistry, sensory physiology, and behavior of insects with respect to olfactory stimulation. This volume, based on a workshop held at the University of Oxford, brings together contributions from leading research workers in a number of disciplines, who present and evaluate the results of recent work, and indicate directions for future research. Considering both behavioral and physiological mechanisms, they treat topics such as the structure of odor plumes, pheromone-induced anemotaxis, orientation along terrestrial trails by ants, neuropharmacological effects on olfactory perception, and epripheral chemoreceptors and regulation of insect behavior.
