Integracao de dados georreferenciados no mapeamento dos biotopos do gafanhoto Praga do mato grosso
Since the 1980's, populations of the grasshopper #Rhammatocerus schistocercoides# (Rehn, 1906) (Acrididae, Gomphocerinae) 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 coordinates 12° 15° S and 51° - 61° W. Through a detailed study which incorporates field data and geoprocessing techniques, maps about suitable and unsuitable biotopes for insect reproduction development and survival were made. An ecological cartography, scale 1:250.000, was developed based on analogic interpretation of LANDSAT TM images and their integration in a geographic information system (GIS), with other basic data, resulting the maps of the grasshopper biotopes. This research provides 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.
