【 摘 要 】

This study evaluated the nocturnal fauna of Noctuidae in a pasture area in Altamira, Pará. Samples were collected monthly for two nights at the new moon period, from August 2007 to July 2008. We collected a total of 345 specimens (N) of 66 species (S). The most abundant species were Ptichodes basilans (Guenée) (n = 87), Leucania jaliscana (Schaus), Spodoptera frugiperda (JE Smith) (n = 28) and Argidia palmipes Guenée (n = 21). For the entire period, the following indexes were found: Shannon diversity H′= 3.20 and Brillouin H = 2.94, evenness of Shannon E′= 0.76 and Brillouin E= 0.76, and Berger-Parker dominance BP= 0.252. The greatest diversity was found in the dry season. According to the estimates of species richness, it is possible that between 14 to 72 more species exist in the region.
