The tolerance of humans to the presence of ants in home environments favors the success of these insects, which are considered urban pests when they infest electronic equipment and wooden structures. Taxonomic identification of species facilitates the development of strategies for their control. The molecular markers Amplified Fragment Length Polymorphism (AFLP) have been used in phylogenetic analysis and in studies of genetic variation, due to the speed and resolution for the analysis of polymorphic alleles. The objective of this study was to survey the biodiversity of urban ants, which occur in households in the city of Uberlândia-MG and to estimate the genetic divergence of the most frequent group of ants in the region, using AFLP markers. Ants were captured with the help of a trap bait, in 120 households. 14 species of ants were registered, the genera Camponotus, Monomorium and Tapinoma, the most frequent. Of the most frequent genus, Camponotus, three species, already morphologically similar, were selected, of which ten individuals were pooled per. species for analysis of genetic divergence, with Monomorium pharaonis as | “Outgroup". 10 combinations of primers from the AFLP ™ Starter Kit were used. , and the genetic differentiation found in this genus corroborates data from the morphometric system.
