To investigate fungal pathogens of Epinotia picea, larvae were collected from an outbreak population occurred at a plantation of Abies veitchii at the foothills of Mt Fuji and reared in the laboratory. Paecilomyces farinosus was frequently found to infect on larvae died during rearing in the laboratory. A small number of infections with Beauveria bassiana and Verticillium lecanii were also found Paecilimyces farinosus, B. bassiana, and V. lecanii were isolated from the soil of outbreak site using selective media. Only B. bassiana was detected from the same soil by the bait method with Galleria mellonella larvae. A high infection rate of overwintered larvae with P. farinosus can be expected in the field.
