This monograph, in its second edition, remains the only comprehensive source of information on economically important forest insects in West Africa. There has been a complete upgrade to all photos, figures, tables and line drawings. Many pest insects discussed have the potential to greatly alter the utilization of these valuable tropical forests. This comprehensive treatise of insects includes information on the general forest cover types and insects of utilitarian value.

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.
This is the first book to explore in detail the world history of humankind's use of bees from prehistoric times to the present day. Both rock art and recent field studies have shown how honey hunters obtained their harvest from bees' nests. Honey has always been the chief prize, but bee brood has been eaten as meat, and beeswax has been utilized in many technologies. Bees, honey, and wax have special symbolic significance in both early beliefs and later world religions. But perhaps bees' greatest benefit has been their pollination of crops.
