Establishment of the fungal entomopathogen Beauveria bassiana (Ascomycota: Hypocreales) as an endophyte in cocoa seedlings (Theobroma cacao)

The fungal entomopathogen Beauveria bassiana became established as an endophyte in in vitro-grown cocoa seedlings tested for up to 2 mo after inoculation to the radicle with B. bassiana suspensions. The fungus was recovered in culture from stems, leaves and roots. B. bassiana also was detected as an epiphyte 1 and 2 mo postinoculation. Penicillium oxalicum and five bacterial morphospecies also were detected, indicating that these were present as endophytes in the seed.
