KEY WORDS: ECOLOGICAL CARTOGRAPHY, GRASSHOPPER, RHAMMATOCERUS SCHISTOCERCOIDES, MATO GROSSO Abstract

Since the 1980's, populations of the grasshopper Rhammatocerus schistocercoides (Rehn, 1906) (, ) have caused damage to the agriculture in savanna areas of the State of Mato Grosso, Brazil. The pullulations occur only in specific biotopes, inside the entire distribution area of the species, located between the geographic coordi- nates 12o -15o S and 51" - 61o WGr. Through a detailed study which incorporates field data and geoprocessing techniques, maps about suitable and unsuitable biotopes for reproduction, development and survival are being made. A static cartography, scale 1:250.000, was developed based on analogic interpretation of LANDSAT TM images; their integration in a geographic information system (GlS), with other basic data, have already been made for a pilot area of 71.399 km2, resulting four thematic maps. The NOAA images are also being used to elaborate the dynamic cartography, which will aim to monitor the phenological evolution of vegetation beyond the pilot area, including other regions with potential infestation risks. This research will provide the basis for a methodological development of remote sensing and geoprocessing applications to approach wide range entomological problems such as this one in Mato Grosso.
