This volume includes 370 papers presented by leading scientists at the 11th International Congress of IUSSI at Bangalore, from August 5-11, 1990. The papers which have been classified into 30 sections relate to the symposia papers of the Congress. These cover various frontiers of research on social insects such as evolution of sociality, polygyny, social polymorphism, kin-recognition, kin- selection, foraging strategies, reproductive strategies, biogeography and phylogenetics of bees and ants pollination ecology and management of pestiferous social insects. The most important feature about these papers in this publication is that the results are presented in a crisp, brief and precise manner. Because of the brevity it has been possible to bring together, in one publication, almost all aspects of research on social insects from all parts of the world. The time between presentation of papers at a Congress and publication has been avoided by publishing this volume on the eve of the Congress and this enables scientists to refer to the results immediately.
Omnipresent in virtually all terrestrial ecosystems and of undisputed ecological and economical importance, the study of social insects is an area that continues to attract a vast number of researchers. As a consequence, a huge amount of information about their biology and ecology has accumulated. Distilling this scattered information into a highly
During the nineteenth and early twentieth centuries, natural and social scientists began comparing certain insects to human social organization. Entomologists theorized that social insects -- such as ants, bees, wasps, and termites -- organize themselves into highly specialized, hierarchical divisions of labor. Using a distinctly human vocabulary that reflected the dominant social structure of the time, they described insects as queens, workers, and soldiers and categorized their behaviors with words like marriage, slavery, farming, and factories. At the same time, sociologists working to develop a model for human organization compared people to insects, relying on the same premise that humans arrange themselves hierarchically. In Debugging the Link between Social Theory and Social Insects, Diane M. Rodgers explains how these co-constructed theories reinforced one another, thereby naturalizing Western conceptions of race, class, and gender as they gained prominence in popular culture and the scientific world. Using a critical science studies perspective not previously applied to research on social insect symbolism, Rodgers attempts to "debug" this theoretical co-construction. She provides sufficient background information to accommodate readers unfamiliar with entomology -- including in-depth explanations of the terms used in the research and discussion of social insects, particularly the insect sociality scale. The entire premise of sociality for insects depends on a dominant understanding of high/low civilization standards -- particularly the tenets of a specialized division of labor and hierarchy -- comparisons that appear to be informed by nineteenth-century colonial thought. Placing these theories in a historical and cross-cultural context, Rodgers explains why hierarchical ideas gained prominence, despite the existence of opposing theories in the literature, and how they resulted in an inhibiting vocabulary that relies more heavily on metaphors than on description. Such analysis is necessary, Rodgers argues, because it sheds light both on newly proposed scientific models and on future changes in human social structures. Contemporary scientists have begun to challenge the traditional understanding of insect social organization and to propose new interdisciplinary models that combine ideas about social insect and human organizational structure with computer technologies. Without a thorough understanding of how the old models came about, residual language and embedded assumptions may remain and continue to reinforce hierarchical social constructions. This intriguing interdisciplinary book makes an important contribution to the history -- and future -- of science and sociology.
With few exceptions, insects are perceived in industrialized countries as undesirable pests. In reality, relatively few insects interfere with us or our resources. Most have benign or positive effects on ecosystem services, and many represent useful resources in non-industrialized countries. Challenging traditional perceptions of the value of insects, Insects and Sustainability of Ecosystem Services explores the ways insects affect the ecosystem services we depend upon. It also fosters an appreciation for the amazing diversity, adaptive ability, and natural roles of insects. The book discusses how the ways in which we manage insects will determine an ecosystem’s capacity to continue to supply services. It reviews aspects of insect physiology, behavior, and ecology that affect their interactions with other ecosystem components and ecosystem services, emphasizing critical effects of insects on the sustainability of ecosystem processes and services. The author examines the integration of insect ecology with self-regulatory aspects of ecosystems that control primary production, energy and nutrient fluxes, and global climate—functions that underlie the sustainability of ecosystem services. Clearly, we need environmental policies that meet needs for pest control where warranted, but do not undermine the important contributions of insects to sustaining ecosystem processes and services. With in-depth coverage of the multiple, often compensatory, effects of insects on various resources or ecosystem services and on the consequences of control tactics for those resources or services, Insects and Sustainability of Ecosystem Services recommends changes in perspectives and policies regarding insects that will contribute to sustainability of ecosystem services.
Claire Detrain, Jean-Louis Deneubourg and Jacques Pasteels Studies on insects have been pioneering in major fields of modern biology. In the 1970 s, research on pheromonal communication in insects gave birth to the dis cipline of chemical ecology and provided a scientific frame to extend this approach to other animal groups. In the 1980 s, the theory of kin selection, which was initially formulated by Hamilton to explain the rise of eusociality in insects, exploded into a field of research on its own and found applications in the under standing of community structures including vertebrate ones. In the same manner, recent studies, which decipher the collective behaviour of insect societies, might be now setting the stage for the elucidation of information processing in animals. Classically, problem solving is assumed to rely on the knowledge of a central unit which must take decisions and collect all pertinent information. However, an alternative method is extensively used in nature: problems can be collectively solved through the behaviour of individuals, which interact with each other and with the environment. The management of information, which is a major issue of animal behaviour, is interesting to study in a social life context, as it raises addi tional questions about conflict-cooperation trade-oft's. Insect societies have proven particularly open to experimental analysis: one can easily assemble or disassemble them and place them in controllable situations in the laboratory.
In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects. Furthermore, in studying the effects of natural selection in generally increasing the insects' ergonomic efficiency, they go beyond the concentration of previous researchers on the physiological mechanisms of the insects and turn our attention instead to the scale and efficiency of the insects' division of labor. Recognizing that the efficiency of the insect colony is based on a complex fitting of the division of labor to many simultaneous needs, including those imposed by the distribution of resources and enemies around the nest, Professors Oster and Wilson are able to construct a series of mathematical models to characterize the agents of natural selection that promote particular caste systems. The social insects play a key role in the subject of sociobiology because their social organization is so rigid and can be related to genetic evolution. Because of this important consideration, the authors' work has consequences not only for entomology but also for general evolutionary theory.
In this book internationally known experts provide a comprehensive view of current knowledge of social insect biology including much previously unpublished information. Particular emphasis is given to the relationships between social insects and humans; sections are devoted to economically important social insects, pollination, foraging, and the role of insects in ecosystems and agroecosystems. The authors also discuss communication, behavior and caste within insect colonies. A special section focuses on the neurobiology of social insects. A series of papers considers the presocial insects, which live in family groups but without caste differences. Also well represented are the fields of sociobiology and the origins and evolution of social behavior. The book will be valuable to agricultural scientists as well as to entomologists, sociobiologists, ecologists, ethologists, and natural historians. Endocrinologists and neurobiologists will also find important new material.
This book represents empirical studies of some aspect of the phenomenon of variability in social insect behavior. It illustrates the range of ways colony members can differ from one another and interprets the variability in terms of the external environment, social context, or individual experience.
