The honey bees were formerly seen as a small, static group comprising four species, whose behavior and ecology were simple variants on the patterns found in Apis mellifera. The picture now is one of a large, actively speciating group, reflecting in part the complex geological and biological influence of the Apis environment. Research on this diversity has benefitted from new techniques of DNA analysis applied to several long-standing problems in honey bee phylogenetics and that are reported in this volume. The behavior and ecology of the Apis species and populations are also more diverse and differentiated than previously recognized: Radically different orientation systems as expressed through dance language exist in various species. This study of Apis will be of great interest not only to biologists and apiculturalists but to anyone interested in systematics, genetics, and ethology. Our view of apis has changed radically in the past few years as a result of recent research on the Asian honeybee. The contributors to this book focus on systematics, genetics, behaviour and ecology to offer a synthesis for understanding this economically and scientifically important genus.

Honeybees are as small as flies or as large as hornets, nesting in nar row cavities of trees and rocks or in the open on large limbs of trees 30 m above ground. They occur in tropical zones and in the forests of the Ural mountains, they survive seven months of winter and even longer periods of drought and heat. Historically, they lived through a extended time of stagnation in the tropics from the mid-Tertiary, but then experienced an explosive evolution during the Pleistocene, re sulting in the conquest of huge new territories and the origin of two dozen subspecies in Apis mellifera. This vast geographic and ecologic diversification of the genus Apis was accompanied by a rich morphological variation, less on the level of species than at the lowest rank, the subspecies level. Variation being exclusively of a quantitative kind at this first step of speciation, tradi tional descriptive methods of systematics proved to be unsatisfactory, and honeybee taxonomy finally ended up in a confusing multitude of inadequately described units. Effective methods of morphometric-sta tistical analysis of honeybee popUlations, centered on limited areas, have been developed during the last decades. Only the numerical characterization of the populations, together with the description of behavior, shows the true geographic variability and will end current generalizations and convenient stereotypes.

A multi-authored work on the basic biology of Asian honeybees, written by expert specialists in the field, this book highlights phylogeny, classification, mitochondrial and nuclear DNA, biogeography, genetics, physiology, pheromones, nesting, self-assembly processes, swarming, migration and absconding, reproduction, ecology, foraging and flight, dance languages, pollination, diseases/pests, colony defensiveness and natural enemies, honeybee mites, and interspecific interactions. Comprehensively covering the widely dispersed literature published in European as well as Asian-language journals and books, "Honeybees of Asia" provides an essential foundation for future research.

Stingless bees are highly social insects which populated the tropical earth 65 million years ago longer than honey bees. They are limited to tropics and subtropics lacking venom apparatus and cannot sting. Impacts of anthropogenic influences on honey bees were already reported. Recent studies also showed that the nesting behaviour of Trigona (Tetragonula) iridipennis Smith in natural habitat also vary due to interaction, pheromones and environmental stimulus. Trigona iridipennis Smith shows great diversity in plant selection for dietary as well as resin sources. The shift towards ornamental plants for foraging may be an adaptation evolved in response to human modification of the environment. The bees collect resin from a variety of sources for building nest, its maintenance and also for defence. Bee traffic is found to be related to time, season, and strength of the colony. The study also highlights the various food sources of Trigona iridipennis Smith in Kerala which can be further explored for flourishing meliponiculture.

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.
