  • An investigation of the severe destruction of wood ear mushroom (Auricularia auricula-judae), which were commercially cultivated in a plastic house in Hwabuk-myeon, Jeju-si, South Korea from April to August 2021, revealed a tenebrionid beetle subsequently identified as Platydema takeii Nakane, 1956 (Coleoptera: Tenebrionidae: Diaperinae). To the best of our knowledge, this is the first report of a tenebrionid species infesting commercially cultivated mushrooms in South Korea. The damage symptoms and diagnosable characteristics of adults and larvae of P. takeii are provided in this study.

  • We conducted field and laboratory observations of the life histories and fungal hosts of the darkling beetle, Platydema nigroaeneum Motschulsky. P. nigroaeneum, a fungivorous tenebrionid beetle, was a widespread inhabitant of fungi on deciduous trees (Quercus, Salix, Alnus and Carpinus etc.) in Korea. Development from egg to adulthood took $4\sim11$ months in nature and about 66 days in the laboratory at $25.5{\sim}26.1^{\circ}C$ and $63.5\sim64.5%$ relative humidity. Both larvae and adults overwintered in their host fungi or beneath the bark of the host tree near the host fungi. Sporophores of Coriolus $Qu{\acute{e}}let$, Bjerkandera Karst., Daedaleopsis Schroet. and Merulius were common feeding and breeding sites in Korea.
