SOARES, Narcisa S. et al. Survey of ants (Hymenoptera: Formicidae) in the urban area of Uberlândia, MG, Brazil. Neotrop. Entomol. [online]. 2006, vol.35, n.3, pp.324-328. ISSN 1519-566X.

Uberlândia, MG, Brazil, underwent an accelerated process of urbanization with a population growth of 3,54% each year, higher than the national average. One of the problems emergent from urbanization is the use of different habitats for a great variety of insects. The objective of this study was to identify species of house-invading ants that occur in the urban area of Uberlândia. The occurrence of the house-invading species in regard to the time of urbanization, neighborhood infrastructure, age and maintenance of private houses was also assessed. The ants were collected using bait-traps in 120 residences from 12 neighborhoods which were put in three groups. Fourteen species of ants were catalogued, with Camponotus (Mayr), Monomorium (Mayr) and Tapinoma (Foerster) being the most frequent genera. Only Camponotus vittatus (Forel), Monomorium pharaonis (L.), Tapinoma melanocephalum (Fabricius) and Brachymyrmex sp. (Mayr) were collected in all three groups. The relation between the ants collected and the age and maintenance of the private houses showed that Paratrechina longicornis (Latreille) was most frequent (60%) in poorly preserved or precarious constructions. Whereas, C. vittatus and Camonotus melanoticus (Emery) occurred in all categories of maintenance. Overall, C. vittatus which had not been found in any previously published survey of urban ants, was the most frequent species in urban areas of the Cerrado.
