The mycological material from an epizootic on Acyrthosiphon pisum Harris on alfalfa was evaluated. Pathogenicity of two isolates of Erynia neoaphidis Remaudière et Hennebert 1980 was tested and compared with the pathogenicity of the same fungus applied via infected aphids. The death rate of infected aphids was primarily influenced by relative humidity, regardless of whether the fungal material came from culture or from dead infected hosts.
