Resumo: | Wasmannia auropunctata (Roger) and Wasmannia rochai Forel are economically important ants in the Southeast and Southwest regions of Bahia State, Brazil. Randomly Amplified Polymorphic DNA (RAPD) markers were used to distinguish and analyze the genetic variability of populations of both species from Ilhéus, Jequié, BA and French Guyana. The genetic distances among W. auropunctata and W.rochai populations (55.8-71.4%) suggest genetic differentiation among them. Wasmannia auropunctata populations from sugarcane and banana plantations in Jequié were the most distant genetically (30.1-46.3%) and may represent populations restricted to isolated fragments. The high genetic distances among W. auropunctata populations from CEPLAC experimental areas, in Ilhéus (26.8-34.6%) and the other populations from Ilhéus (23.3-40.8%), suggest a multicolonial structure of W. auropunctata in southeast Bahia. The genetic proximity among the W. auropunctata populations from cocoa (14.1%) and coconut plantations (18.5%) in Ilhéus with the populations from the French Guyanan forests suggest that there was recent and large expansion of populations derived from a single population, that are today distributed in habitats with similar environmental characteristics. The high polymorphism and the estimated heterozygosity values for the two species suggest that we studied native W. auropunctata and W.rochai populations.
