Investigations on fungal pathogens of Epinotia picea (Issiki) (Lepidoptera: Tortricidae) in an outbreak population occurred at a plantation of Abies veitchii Lindl. on Mt. Fuji

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. Abies veitchii at the foothills of Mt Fuji and reared in the laboratory. Abies veitchii Paecilomyces farinosus was frequently found to infect on larvae died during rearing in the laboratory. A small number of infections with Beauveria bassiana and Beauveria bassiana and Beauveria bassiana Verticillium lecanii were also found. Verticillium lecanii were also found. Verticillium lecanii 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 B. bassiana was detected from the same B. bassiana soil by the bait method with Galleria mellonella larvae. A high infection rate of overwintered larvae with P. farinosus can be expected in the fi eld.
