For many agricultural crops, bees play a vital role as pollinators, and this book discusses the interplay among bees, agriculture, and the environment. Although honey bees are well recognized as pollinators, managed bumble bees and solitary bees are also critical for the successful pollination of certain crops, while wild bees provide a free service. As bees liberally pass pollen from one plant to the next, they also impact the broader ecosystem, and not always to the benefit of humankind. Bees can enhance the unintentional spread of genes from genetically engineered plants, and may increase the spread of invasive weeds. Conversely, genetically engineered plants can impact pollinators, and invasive weeds can supply new sources of food for these insects. Bees' flower-visiting activities also can be exploited to help spread biological control agents that control crop pests, and they are important for native plant reproduction. Managing bees for pollination is complex and the factors that must be taken into consideration are treated here, including bee natural history, physiology, pathology, and behavior. Furthermore, transporting bees from native ranges to new areas for pollination services can be controversial, and needs to be done only after assuring that it will not disrupt various ecosystems. Even though bees are small, unobtrusive creatures, they play large roles in the ecosystem. The connection between bees and humankind also is symbolic of a broader interconnection between humans and the natural world.

Pollination is the process by which pollen is transferred from the male part of a plant to the female part. This enables fertilization and the production of seeds. Usually, pollination occurs within a species, but in cases where it occurs between two different species, a hybrid offspring is produced. Self-pollination occurs when pollen from the same plant reaches the stigma of a flower or ovule. Pollination is often aided by animals such as birds, insects and bats as well as by the wind, rain and water. Nearly 3/4th of world's supply of food is derived from plants that require pollination. The financial and ecological advantage of natural pollination by native pollinators in the case of agricultural crops can be witnessed in their improved quality and yield. However, there is a recent decline in pollinator populations owing to habitat destruction, pesticide use, climate change and parasitism or disease. Pollination management is thus vital to modern agriculture. Efforts to protect and enhance pollinators, and add new pollinators to monoculture situations, as in commercial fruit orchards, are important for better agricultural productivity. This book elucidates the concepts and innovative models around prospective developments with respect to utilizing pollination for improving the health of agricultural ecosystems. It consists of contributions made by international experts on pollination and pollinating agents. It will help new researchers by foregrounding their knowledge in this area.

It is only recently that the immense economic value of pollination to agriculture has been appreciated. At the same time, the alarming collapse in populations of bees and other pollinators has highlighted the urgency of addressing this issue. This book focuses on the specific measures and practices that the emerging science of pollination ecology is identifying to conserve and promote animal pollinators in agroecosystems. It reviews the expanding knowledge base on pollination services, providing evidence to document the status, trends and importance of pollinators to sustainable agricultural production. It provides practical and specific measures that land managers can undertake to ensure that agroecosystems are supportive and friendly to pollinators. It draws on the Global Pollination Project, supported by UNEP/GEF and implemented by FAO and seven partner countries (Brazil, Ghana, India, Kenya, Nepal, Pakistan and South Africa), which serve to provide "lessons from the field".

This publication addresses the need to strengthen the interface between the scientific community, knowledge-holders and policymakers, and build capacity for and strengthen the use of science and knowledge in policymaking on the topic of ecosystem services. With respect to the ecosystem service of pollination, FAO developed a protocol to identify and assess pollination deficits in crops – resulting in a global meta-analysis, with data from eleven countries. Results emerging from this endeavour give strong indication that pollination deficits may exist in a wide variety of farming systems across the world. As a response to this science, researchers and policymakers from the eleven countries considered the range and types of actions that can address pollination deficits, and developed an indicative set of policy responses. This publication is a result of this work, which considers the mainstreaming of ecosystem services at both national and international levels, with a focus on pollination services.

Just as flowering plants depend on their pollinators, many birds, insects, and bats rely on plants for energy and nutrients. This plant-pollinator relationship is essential to the survival of natural and agricultural ecosystems. Plant-Pollinator Interactions portrays the intimate relationships of pollination over time and space and reveals patterns of interactions from individual to community levels, showing how these patterns change at different spatial and temporal scales. Nickolas M. Waser and Jeff Ollerton bring together experts from around the world to offer a comprehensive analysis of pollination, including the history of thinking about specialization and generalization and a comparison of pollination to other mutualisms. An overview of current thinking and of future research priorities, Plant-Pollinator Interactions covers an important theme in evolutionary ecology with far-reaching applications in conservation and agriculture. This book will find an eager audience in specialists studying pollination and other mutualisms, as well as with biologists who are interested in ecological, evolutionary, and behavioral aspects of the specialization and generalization of species.

Plants are the basic source of food for both humans and animals. Most of the food is made of fruits and seeds. For these to be formed, pollination must first take place. This process is the transfer of pollen grains from the anther, which is the male structure of the flower, to the sigma on the female structure of the flower. The transfer process requires agents to be carried out. The agents can be either biotic or abiotic. Nature perfected this arrangement between the pollination agents and the plants. As ecosystems and agricultural systems are changing, this balanced arrangement becomes disturbed. This makes it necessary that pollination systems be studied so that necessary measures can be undertaken to ensure productivity. The chapters of this book present results in research undertaken to improve productivity in crops such as Actinidia chinensis (the kiwifruit), Theobroma cacao (cocoa), and Manicaria saccifera (a tropical forest palm). Some results are presented on tests to check the viability of pollen grains and the delivery of sperm cells through pollen tubes to the embryo sac. These results can serve as guidelines to any person seeking to improve pollination and productivity or to check the efficiency on pollination in ecosystems or agricultural production systems.

Since the second half of the 20th Century, our agricultural bee pollinators have faced mounting threats from ecological disturbance and pan-global movement of pathogens and parasites. At the same time, the area of pollinator-dependent crops is increasing globally with no end in sight. Never before has so much been asked of our finite pool of bee pollinators. This book not only explores the evolutionary and ecologic bases of these dynamics, it translates this knowledge into practical research-based guidance for using bees to pollinate crops. It emphasizes conserving wild bee populations as well as culturing honey bees, bumble bees, and managed solitary bees. To cover such a range of biology, theory, and practice from the perspectives of both the pollinator and the crop, the book is divided into two volumes. Volume 1 focuses on bees, their biology, coevolution with plants, foraging ecology and management, and gives practical ways to increase bee abundance and pollinating performance on the farm. Volume 2 (also available from CABI) focuses on crops, with chapters addressing crop-specific requirements and bee pollination management recommendations. Both volumes will be essential reading for farmers, horticulturists and gardeners, researchers and professionals working in insect ecology and conservation, and students of entomology and crop protection.
