RESUMO
Twenty four strains of the entomopathogenic fungi (Hyphomycetes) Beauveria bassiana, Metarrhizium anisopliae, Nomuraea rileyi, Paecilomyces farinosus, P. fumosoroseus and P. lilacinus, maintained in the culture collection of Embrapa-Centro Nacional de Pesquisa de Recursos Geneticos e Biotecnologia (Cenargen) and preserved by lyophilization and in liquid nitrogen, had their conidial viability assessed. Germination rates of 16- to 84-month-old cultures stored in liquid nitrogen decreased, on average, less than 13.3%. For 29- to 49-month-old cultures preserved by lyophilization, the viability loss ranged, on average, from 28.6 to 94.5%. The results demonstrated the efficiency of the tested methods, especially liquid nitrogen, in preserving the viability of entomopathogenic fungi.
