초록

국내 미기록 곤충병원사상균, Hirsutella subulata를 볏짚 내의 이병된 나비목의 이화명충(Chilo suppressalis)에서 발견하였다. 이 균은 유충 표면에서 여러 개의 분생자경속(synnemata)과 그 표면에 가늘고 긴 목을 지닌 반곤봉모양의 경자(phialide)를 형성하며, 분생포자의 모양은 비대칭형으로 한쪽 면이 둥근 특징을 지니고 있다. 이 균은 H. barberi와 형태적으로 매우 유사하나, 분쟁자의 형태로 구분이 가능하다.

Hirsutella subulata (Hyphomycetes) was observed for the first time on diseased larvae of Chilo suppressalis in Korea. This fungus formed slender and slightly attenuated synnemata consisting of closely bound, longitudinal hyphae on the insect larvae. Typical characteristics of this species are ellipsoid or broadly obovoid phialides with slender, needle-like necks and asymmetric conidia. It is very similar to H. barberi but can be distinguished by its asymmetrical conidia.
