Diomea cremata (Lepidoptera: Noctuidae) as a Pest of Shiitake Mushroom, Lentinula edodes (Agaricaceae)

Abstract

We observed that a fungivorous moth, Diomea cremata damaged the shiitake mushroom, Lentinula edodes (Berk.) Pegler cultivated on synthetic logs (mainly composed of sawdust), which have replaced the use of natural logs over the last decade. It is considered that D. cremata has become a new pest of this fungus. The larvae appear to consume the thick brown mycelial coat formed on the surface of synthetic logs rather than the fresh fruit body.
