摘要：Beauveria bassiana is an insect-associated fungal species and it is economically important as an environment-friendly mycoinsecticide and a good source of biologically active secondary metabolites. In this study, we employed DNA microsatellite markers to investigate the infra-specific diversity of 102 isolates of B. bassiana sensu stricto from India. All the microsatellite markers were easily amplifiable for all the isolates and provided a good genotype resolution. The microsatellite analysis indicated the presence of highly polymorphic, randomly distributed populations of B. bassiana with variable host range and apparently no host-specificity. We, however, observed region-wise clustering of the populations within B. bassiana sensu stricto from India
