RESUMO
This study was carried out to analyze the genetic population structure of Atta capiguara from 12 nests collected in Tapejara in the state of Paraná, Brazil, using isoenzyme polymorphisms. The analyzed isoenzymes were esterases (EST - EC 3.1.1.1), acid phosphatase (ACP - EC 3.1.3.2) and carbonic anhydrase (CA - EC 4.2.1.1). Ten loci were found in A.capiguara and four polymorphic loci were detected. The observed heterozigosity (0.0296) was low when compared to the expected heterozigosity (0.1461). The high value of F IS (0.7954) shows an excess of homozygous genotypes probably caused by inbreeding.
