The recent development of information technology (IT) had its impact on applied science, and particularly on plant protection. The entomologists found IT an excellent tool to develop simulation models for insect populations. But the IT did not exhaust its potential in this domain. One of the new IT promises in Plant Protection is database organization at large scales that allow monitoring mega pest populations on wide areas. In this presentation we will show how we organized an Oracle database as part of our Area Wide Pest Management (AWPM) project and what the important features of this kind of activity are. The AWPM database contains the results of field sampling of aphid populations (main species) and their predators and parasitoids that encompass six states in the south-central Great Plains of the United States. The AWPM database is considered as a starting point for future development. Particularly it will be linked with GIS software for spatial-temporal analysis. The result will be displayed on web pages as operative real-time information source for growers.
