한국산 미기록종 가시넓적거저리[Bolitophagiella pannosa(Lewis)]의 생활사 연구

Abstract

넓적가시거저리[Bolitophagiella pannosa (Lewis)]는 국내에서 처음 보고되는 종으로 성충에 대한 기재문을 제공하였고, 야외관찰과 실내사육을 통해 다음과 같은 간략한 생활사를 밝혔다. 넓적가시거저리는 균식성 곤충으로 활엽수림에 나는 버섯, 특히 흰구멍장이속(Perenniporia)에 속하는 국내미기록종인 P. medulla-panis (Fr.) Donk와 아까시재목버섯[P. frazinea (Fr.) Ryv.]을 선호하였고, 성충과 유충이 혼재된 상태로 숙주버섯의 자실체 속이나 숙주버섯이 붙어있는 나무껍질 밑에서 월동하였으며, 실내사육(25.5<TEX>${\sim}$</TEX><TEX>$26.1^{\circ}C$</TEX>; 63.5<TEX>${\sim}$</TEX>64.5% RH)한 결과 알에서부터 성충까지 약 54일이 소요되었다. A taxonomic review of a new record, Bolitophagiella pannosa (Lewis) in Korea is presented. Description of adult is presented and also we conducted laboratory and field observations of the life history and fungal hosts of the darkling beetle, Bolitophagiella pannosa (Lewis). A fungivorous tenebrionid beetle, Bolitophagiella pannosa (Lewis), was a rare inhabitant of fungi on deciduous trees (Quercus, Robinia pseudoacacia etc.) in Korea. Development from egg to adulthood took 3<TEX>${\sim}$</TEX>10 months in nature and about 54 days in the laboratory at 25.5<TEX>${\sim}$</TEX><TEX>$26.1^{\circ}C$</TEX> and 63.5<TEX>${\sim}$</TEX>64.5% 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 Perenniporia medulla-panis (Fr.) Donk and Perenniporia frazinea (Fr.) Ryv. were obligate feeding and breeding sites in Korea. Description, habitus photographs of adult and instar, and illustrations of diagnostic characters are provided.
