The field guide documents the community of insects that feed on rice in the tropical zone of Asia and complements the IRRI publication "Helpful insects, spiders, and pathogens: friends of the rice farmers." It covers 78 phytophagous species in 64 genera, 27 families, and 8 orders. The phytophage guild represents five groups-general defoliators, (27 species), plant suchers (25 species), early vegetative pests (11 species), soil pests (9 species), and stem borers (6 species). Stem borers and plant suckers comprise the major rice pests. A brief description of each insect's life stage and demage it does to the rice plant is presented for a quick and reliable identification.
In order to achieve economic efficiency, research organizations have established rigorous, quantitative methods for priority setting. One such organization, the Rockefeller Foundation, has drawn on this report to help determine the research goals it should emphasize in its funding. A review of the problem of priority setting is presented followed by a discussion of approaches that have been used previously. Several chapters demonstrate how a number of areas of plant science research have contributed to gains in rice productivity and also assess the current challenges of genetic improvement and pest control. The economic framework for priority setting and previous methods are reviewed, followed by a series of country case studies which provide more practical applications.

The four-day international Conference on Pest Management in Rice, which is the subject of this volume, was the third in an ongoing series of meetings on tropical crops organised by the Pesticides Group of the Society of Chemical Industry, London. The participants came from both the public and private sectors and from many different countries. All the major groups of pests-weeds, microorganisms, arthropods and rodents-were considered, as the organisers believe that it is necessary to address the total pest management problems in each particular growing area, and the variety of the papers indicates the importance of a multi disciplinary approach to their solution. Rice is one of the most important world crops and is the major source of food for around 60% of the world's population, with a world production of 500 million tonnes from 150 million hectares of land. Since world stocks amount to only two months supply, many people are at risk from famine. Moreover, it has been esti mated that the world requirement in 2020 will be about 760 million tonnes, an increase of 50%. This pressure of population on food makes efficient pest management vital and is the reason for bringing together experts from all over the world to this major conference.
