Dipteran fauna associated with decaying organic matter in semi-deciduous forest fragments in southern Goiás, Brazil

Abstract

Dipteran diversity was studied in four seasonal, semi-deciduous forest fragments in southern Goiás state, Brazil. Species richness of Muscidae, Calliphoridae and Sarcophagidae families was analyzed. The insects were collected each two months over the course of one year, using traps with decaying bait. The traps were kept in the field for five days each sampling period. A total of 1,956 individuals belonging to 13 families were collected. 29 species were identified belonging to the main families. Muscidae had the highest abundance, while Sarcophagidae presented the greatest number of species. We also report the occurrence of Philornis schildi (Muscidae) for the first time in Brazil. These data reinforce the importance of preserving these areas, and indicate the need for new studies to improve knowledge of the biodiversity associated with these fragments. This information may also be useful in future studies regarding the impact of human activity on insect fauna associated with this environment.
