Abstract: Ant fauna (Formicidae, Hymenoptera) in an urban fragment area of semideciduous mesophitic forest. We investigated the diversity of ants in an urban fragment area of semideciduous mesophitic forest. Besides, we evaluated differences in the visiting between sardine and honey traps. The sampling was made weekly. The samples were made with sardine and honey baits disposed in 15 transects on the soil and above the vegetation. A total of 26 ant species were collected, (eight genera and four subfamilies) Camponotus Mayr, 1861 and Pheidole Westwood, 1841 were the most common genera. The major diversity values were found for sardine traps. The high diversity of ant fauna (Shannon-Weaver index) may be related to higher local environment heterogeneity and competition for resources. The rarefaction curve showed a fast increase in number of species and the slope indicated a possible stabilization. We verified that ant fauna visiting baits in an urban fragment area may be relatively rich and that the use of bait traps is practical and efficient to capture it.
Key words: Formicidae, diversity, semideciduous mesophitic forest, bait, urban area.
