The Pampas, which occupies the Province of Buenos Aires and parts of the Provinces of Entre Ríos, Santa Fe, Córdoba, La Pampa and San Luis, are temperate subhumid grasslands. Mesothermic grasses dominate in this region of mild climate with mean annual temperature ranging from 10 to 20°C, and annual rainfall between 400 and 1600 mm. There is a general decrease southwestward in annual precipitation, soil organic matter and grassland productivity.

The landscape has been altered markedly during the last century due to agricultural and grazing activities, and pristine grasslands have been drastically modified. Most of the land has been converted to cropland, mainly soybean, corn, sunflower and wheat.

Among the most important native herbivores are grasshoppers, which are a recurrent pest of the agro ecosystems of this area. These insects may cause, in some years, forage and crop losses of considerable magnitude.

The Pampas and the Great Plains of North America have some ecological...
