Recombination mediated through a parasexual cycle is a potential source of genetic diversity amongmitosporic fungi such as Beauveria bassiana. Knowledge of this diversity is critical to understand thestructure of the population. Therefore, the aim of this study was to analyze the genetic diversity within36 Argentinean isolates of B. bassiana collected from different geographical regions and insect hosts; andto assess by means of ITS sequences the preliminary taxonomic position of the isolates that might berelated to the phenotypic and genotypic differences. The results demonstrate that the fingerprints generatedwith four ISSR markers were enough to detect significant genetic diversity among Argentinean isolates,which was unrelated neither with the geographical origin nor with insect hosts.
