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

The stingless bees are one of the most diverse, attractive, fascinating, conspicuous and useful of all the insect groups of the tropical world. This is a formidable and contentious claim but I believe it can be backed up. They are fifty times more species rich than the honey bees, the other tribe of highly eusocial bees. They are ubiquitous in the tropics and thrive in tropical cities. In rural areas, they nest in a diversity of sites and are found on the flowers of a broad diversity of crop plants. Their role in natural systems is barely studied but they almost certainly deserve that hallowed title of keystone species. They are popular with the general public and are greatly appreciated in zoos and gardens. The chapters of this book provide abundant further evidence of the ecological and economic importance of stingless bees.

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.

This book provides updated information on this intriguing and exciting group of insects: Neotropical Social Wasps. These insects have a particular biology and their colonies are formed by a few cooperative females living in either small or massive, structured nests where stinging individuals organize their activities and defend their offspring. Topics include evolutionary aspects, biogeography, post-embryonic development, community behavior and ecology, economic importance, and research methods.

This volume explains the key ideas, questions and methods involved in studying the hidden world of vibrational communication in animals. The authors dispel the notion that this form of communication is difficult to study and show how vibrational signaling is a key to social interactions in species that live in contact with a substrate, whether it be a grassy lawn, a rippling stream or a tropical forest canopy. This ancient and widespread form of social exchange is also remarkably understudied. A frontier in animal behavior, it offers unparalleled opportunities for discovery and for addressing general questions in communication and social evolution. In addition to reviews of advances made in the study of several animal taxa, this volume also explores topics such as vibrational communication networks, the interaction of acoustic and vibrational communication, the history of the field, the evolution of signal production and reception and establishing a common vocabulary.

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.

The stingless bees are the most diverse group of highly social bees and are key species in our planet’s tropical and subtropical regions, where they thrive. In Mexico, the management of stingless bees dates back centuries, and they were an essential part of the culture and cosmogony of native peoples like the Maya. In recent decades a vast amount of information has been gathered on stingless bees worldwide. This book summarizes various aspects of the biology and management of stingless bees, with special emphasis on the Mexican species and the traditions behind their cultivation. Much of the information presented here was produced by the author and the team of researchers at the Universidad Autónoma de Yucatán in the course of three decades of working with these insects. Given the breadth of its coverage, the book offers an equally valuable reference guide for academics, students and beekeepers alike.

The future role of dwarf honeybees in natural and agricultural systems provides multidisciplinary perspective about the different facets of dwarf honeybees. The role of dwarf honeybee Apis florea assumes utmost importance in the context of pollinator decline throughout the world threatening stability of ecosystems and global food security. Apis florea is a low land species of south Asia extending more to the west than other Asiatic Apis species. It is an important pollinator of crops in hot and dry agricultural plains. The book is first of its kind which deals in details on varied aspects of Apis florea biology, management, conservation strategies for protecting biodiversity and enhancing crop productivity. The book aims to promote a large, diverse, sustainable, and dependable bee pollinator workforce that can meet the challenge for optimizing food production well into the 21st century. Features: Apis florea provides source of livelihood in mountainous areas and marginal farmers. This book will for the first time present the beekeeping from the perspective of agricultural production and biodiversity conservation An excellent source of advanced study material for academics, researchers and students and programme planners Excellent pollinator of tropical and subtropical crops fruits vegetables etc less prone to diseases and enemies Covering the latest information on various aspects of Apis florea biology, this book brings the latest advances together in a single volume for researchers and advanced level students This book will be useful to pollination biologists, honeybee biologists in entomology departments, students, teachers, scientists of agriculture, animal behaviour, botany, conservation, biology, ecology, entomology, environmental biology, forestry, genetics, plant breeding, horticulture, toxicology, zoology, seed growers and seed agencies and shall serve as reference book for students, teachers, researchers, extension functionaries and policy planners.

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.
