Flight height of bostrichids (Coleoptera: Bostrichidae) collected in Tropical Semideciduous Forest, Mato Grosso, Brazil

Abstract

The objective of this study was to determine the flight height of species of Bostrichidae family, as well as determine the faunistic index of species collected in Tropical Semideciduous Forest, in the period to April of 2000 at March of 2001, in Maracaí farm, located in the municipality of Sinop, Mato Grosso, Brazil. Seven heights with 21 ethanolic traps were tested, with three traps by height. The bait used was the commercial alcohol and the collects were proceeded every fifteen days, and latter on monthly. The material collected was identified by comparison with specimens of the Forest Protection laboratory collection, from the Federal University of Mato Grosso. Were collected 141 individuals from five species: Bostrychopsis uncinata, Micrapate brasiliensis, Micrapate germaini, Xyloperthella piceae and Xyloprista praemorsa. The collects of most species of Bostrichidae, were significantly higher at 30 meters. The most frequent and dominant species captured was X. picea. This species presented the higher peak of occurrence in June and February, significantly different from the other species. In the studying period, it was not observed significant correlation between climate and the occurrence of the studied species.
