Natural ocurrence of entomopathogenic fungi in soils cultivated with Paraguay tea (Ilex paraguariensis St. Hil.) in Misiones, Argentina. Rev. argent. microbiol.

This study aimed to morphologically isolate, identify and characterize entomopathogenic fungi present in soils cultivated with Paraguay tea (Ilex paraguariensis). A survey of native entomopathogenic fungi was conducted from 40 soil samples grown with Paraguay tea in the province of Misiones, Argentina, from May 2008 to June 2010. The soil dilution plate methodology on selective culture media was used to isolate microorganisms. Taxonomic identification was performed using macroscopic and microscopic characters and specific keys. Twenty nine strains, belonging to the species Beauveria bassiana (n = 17), Metarhizium anisopliae (n = 2) and Purpureocillium lilacinum (n = 10) were isolated and identified.

Keywords : Paraguay tea; Beauveria bassiana; Metarhizium anisopliae; Purpureocillium lilacinum.
