摘要: Grasshoppers (Orthoptera, Acridoidea) in native savanna and crop areas Chapada dos Parecis, Mato Grosso State, Brazil. We determined the composition abundance of grasshoppers using sweep net sampling during three years at Parecis Plateau, State Grosso, The survey was done with crops vegetation (savanna) with, respectively, 56 59 sites available each environment. 3.031 individuals were collected from 64 species distributed among following families subfamilies: Acrididae (49): Gomphocerinae (21), Ommatolampinae (10), Melanoplinae (6), Acridinae (4) Leptysminae (3), Copiocerinae Proctolabinae (1) Cyrtacanthacridinae (1); Romaleidae (1): Romaleinae (13) Ommexechidae Ommexechinae (2) 1550 nymphs. differences significant between number found savannas (61) cultived (16). However, Acridoidea significantly higher than which influenced mainly by two Acrididae's species: Baeacris punctulatus (Thunberg, 1824) Orphulella punctata (De Geer, 1773) accounted for 49.5% total across Plateau and, together, they account 78.8% recorded areas, both being potential pests.
