Abstract

This study was conducted to investigate optimal conditions for formation of synnemata from Beauveria bassiana. The strain of B. bassiana was isolated from a host of Oncotympana fuscata in Halla mountain of Jeju island. The yield of synnemata was the highest at application of brown rice (90%) and silkworm pupae (10%) media. On the other hand, the other media did not result in formation of synnemata. The highest formation of synnemata was achieved at conditions of moderate air inflow and $20^{\circ}C$. The optimal moisture and light intensity for formation of synnemata were 60% and 300 lux, respectively. In addition, inoculation of the liquid spawn resulted in higher yield than that of asexual spore.

백강균(Beauveria bassiana)의 분생자병속 형성 조건 구명을 위해 본 실험을 수행하였다. 균은 제주도 설악산 일대에서 치사한 참매미로부터 분리되었다. 분생자병속 형성 유도 배지는 현미와 누에번데기를 원료로 하여 90:10 비율로 조제한 경우가 가장 효과적이었으며, 기타 배지 상에서는 분생자병속 발생이 관찰되지 않았다. 분생자병속은 공기 유입량이 최소일 때 형성이 효과적이었으며, 분생자병속 발생의 최적 온도는 $20^{\circ}C$, 배지 수분함량은 60% 및 조도 300 lux이었다. 또한, 증식에 활용한 종균은 액체배양균이 무성포자보다 분생자병속 형성에 더욱 효과적이었다.
