Microsatellite variability in the entomopathogenic fungus Paecilomyces fumosoroseus: genetic diversity and population structure.

The hyphomycete Paecilomyces fumosoroseus (Pfr) is a geographically widespread fungus capable of infecting various insect hosts. The fungus has been used for the biological control of several important insect pests of agriculture. However knowledge of the fungus' genetic diversity and population structure is required for its sustainable use as a biological control agent.
