Infection of the coffee berry borer Hypothenemus hampei (Coleoptera : Scolytidae) by brazilian isolates of the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae (Deuteromycotina : Hyphomycetes).
The virulence of four fungal isolates (three Beauveria bassiana and one Metarhizium anisopliae) against adultfemale coffee berry borers (CBB) was investigated. The most virulent isolate from initial bioassays, B. bassiana LPPI, with a LT50 of 3.4 days, was further investigated by application to berries prior to infestation and to berries already infested with CBB. At the highest concentration applied to berries (J x ]07 conidia mL -I), CBB mortality was 83% (berries inoculated prior to infestation ) and 62% (berries inoculated after infestation).
