Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

This bulletin, based on contributions from various contributors and edited by Dr. D.W. Roubik, introduces the reader to various aspects of natural and insect pollination. It discusses the pollinators themselves, and the ecological and economic importance of pollination, as well as applied pollination in temperate, tropical oceanic islands and mainland tropics, and alternatives to artificial pollinator populations. Prospects for the future are also discussed. Chapter 2 deals with successful pollination with pollinator populations, the evaluation of pollinators and floral biology and research techniques. The behaviour of pollinators and plant phenology and various case studies on the preparation of pollinators for use in tropical agriculture are also discussed. A glossary and various appendices regarding cultivated and semi-cultivated plants in the tropics, pollination contracts and levels of safety of pesticides for bees and other pollinators are included.
