| Abstract | Moving IPM to larger spatial scales and higher levels of integration. The operational unit for most IPM programs implemented throughout the world to date has been the individual crop field. Depending on the crop and the region of the world a crop field can be just a fraction of a hectare, as the small holdings of subsistence farmers in Asia,Africa,or Central and South America,or the small plots of speciality vegetable or ornamental seed producers in developed countries of Europe and North America.At the other extreme, fields can cover several thousand hectares of a monocrop, such as soybean, in the western reaches of the states of Rondonia and Mato Grosso, Brazil.There are inherent difficulties in implementing IPM in very small or in very large fields. Current programs, based on local scouting and field based economic injury levels to support control decisions, perform at their best if the target field unit ranges from ten to a few hundred hectares. There are reasons for this dependency of current IPM programs on field size and these will be discussed in greater detail. IPM represents a significant advancement over pest control systems of the 1940s, 50s, and 60s that were based on calendar sprays.The level of integration of some of the best programs, however, still is limited to the use of combinations of a few control tactics for individual pests in each pest category (insects, pathogens, weeds, etc.). Seldom are interactions among pest classes taken into consideration and cropping systems often are adopted with little or no consideration of ecological impacts, particularly impacts on pest incidence and severity. The need for consideration of these multiple factors for the advancement of IPM to higher levels of integration is imperative. To advance pest management systems to higher levels of integration it will be necessary to expand 1 Presentado en la Serie de Conferencias Científicas Interamericanas Henry A.Wallace "Globalización de la Investigación Agrícola (2002, Turrialba, Costa Rica). 2 Centro de Protección Integral de Plantas y Departamento de Entomología, Oregon State University.
