Faunistic analyses of grasshoppers in the National Forest of Chapecó, Santa Catarina, Brazil
A study of the grasshopper fauna was performed through samples collected in three vegetal types in the National Forest of Chapecó. Weekly collections were carried out from December 2003 to December 2004. Pitfall traps, sweep nets, entomological umbrellas and malaise traps were used. Collections were repeated in areas with eucalyptus trees, native species and pine trees. The fauna found in different areas was classified by its abundance, constancy, dominance and frequency. Eighteen species were common in the three areas. Staurorhectus longicornis longicornis, Cylindrotettix sp. and Ommexecha virens were found only in eucalyptus and pine areas. Scotussa lemniscata and Zoniopoda tarsata were found in areas with eucalyptus and native trees. Amblytropidia sp. was found only in native vegetation and pines areas. Tridactylus politus was found just in the pine area. Allotruxalis gracilis, Dichroplus elongatus, Dichroplus misionensis and Ronderosia bergi were very frequent, dominant and very abundant in the eucalyptus tree area. A. gracilis, M. adspersa and D. misionensis were very frequent, dominant and very abundant in the native tree area. Metaleptea adspersa and R. bergi were very frequent, dominant and very abundant in the pine area. A similarity in diversity of species was verified with greater abundance in the eucalyptus area.doi: 10.4336/2011.pfb.31.65.43
