[en] In the Valley of Calamuchita (Córdoba-Argentina), a forested area with 36,202 ha. of Pinus spp., it has been developed from 1996 a Geographical Information System (GIS) as a complementary tool for the study of the pest Sirex noctilio Fabricius. The objective is to store, to organize, to contrast and to analyze the obtained data of the study of Sirex noctilio F., with the purpose of generating new information that will serve as a basis in the definition of a strategy of pest management. In seven operative areas, were establishied points of sampling in permanent transects across different sites. In each one it was registered, degree attacks of the pest, management, density and age of the stand and its geographical position with GPS. The GIS was carried out with the data originated from the monitoring. The GIS was integrated by a space database and a database with thematic information. The result consisted on the elaboration of analogical maps by means of the visual analysis of pictures at 1:50.000 scale, digital prosessing of LandSat TM 5 satellite images and elaboration of thematic maps. In the conversion of analogical to digital information, it was used the vectorial system ARC/INFO. The pattern entity-relationship were the approache utylized for the generation of databases. The software used was the Visual dBASE, 1995. This information was modeled cartographically with the software ARCVIEW. As resulted of these activities is possible to have a data base from the last five sampling. It allows to understand not only the attack levels and their temporal variation, but also other aspects of the plantations like composition, management, density and estimated age.

[es] En el Valle de Calamuchita (C&oacute;rdoba-Argentina), &aacute;rea forestada con 36.202 ha. de Pinus spp., se trabaja desde 1996 en un SIG (Sistema de Informaci&oacute;n Geogr&aacute;fica) como herramienta complementaria para el estudio de la plaga Sirex noctilio Fabricius (Hymenoptera-Siricidae). El objetivo es almacenar, organizar, contrastar y analizar los datos obtenidos del estudio de Sirex noctilio F., con el fin de generar nueva informaci&oacute;n, que servir&aacute; como base en la definici&oacute;n de una estrategia de manejo de la plaga. En siete &aacute;reas operativas se establecieron estaciones de muestreo, donde se instalaron transectas permanentes atravesando distintos ambientes, registr&aacute;ndose grado de ataque de la plaga, manejo, densidad, edad del rodal y su posici&oacute;n geogr&aacute;fica con GPS. Con los datos aportados por el monitoreo se realiz&oacute; el SIG integrado por una base de datos espacial y una base de datos con informaci&oacute;n tem&aacute;tica. La entrada de datos consisti&oacute; en la elaboraci&oacute;n de mapas anal&oacute;gicos por medio del an&aacute;lisis visual de fotogramas escala 1:50.000, procesamiento digital de im&aacute;genes satelitales LandSat TM 5 y elaboraci&oacute;n de mapas tem&aacute;ticos. En el pasaje de la informaci&oacute;n anal&oacute;gica a digital se utiliz&oacute; el sistema vectorial ARC/INFO, para la creaci&oacute;n de la base de datos los criterios fueron del modelo entidad-relaci&oacute;n y el software utilizado el Visual dBASE, 1995. Esta informaci&oacute;n fue modelada cartogr&aacute;ficamente con el software ARCVIEW. Como resultado de estas actividades se cuenta con una base de datos obtenida durante el monitoreo de los &uacute;ltimos cinco a&ntilde;os, que permiten conocer no s&oacute;lo la situaci&oacute;n de los macizos forestales en cuanto a niveles de ataque y su variaci&oacute;n en el tiempo, sino tambi&eacute;n otros aspectos como composici&oacute;n, manejo, densidad y edad estimada de las plantaciones.
