Mass-Rearing of Mulberry Wild Silkworm, Bombyx mandarina Moore, (Lepidoptera : Bombycidae) in Laboratory

한국산 멧누에나방(Bombyx mandarina M.)의 실내사육

To establish the succeeding generations of wild silkworms, Bombyx mandarina Moore, massrearing was made in the laboratory. The rearing result was good under high humidity and moderately warm condition. Larval periods were 15 to 25 days and the most of larval period was around 17 days. The pupation rate and the pupal period of most of males and females were 40% and 13 to 25 days, respectively. There were two emergence peaks of males and females, and males emergence peak occurred two or three days faster than females.

멧누에는 실내에서의 대량사육이 곤란한 것으로 알려져 왔으나 부화에서부터 100%가까운 다습상태와 $27^{\circ}C$전후의 고온사육조건에서 간단히 사육할 수 있었다. 실내사육결과 전령경과일수는 15~25일의 범위이며 대부분의 유충은 17일 전후이었다. 용화비율은 약40%이며 용기간은 암수모두 13~25일 사이였다. 또한 암수모두 2개의 우화최고점을 가지며 수컷이 암컷에 비해 2~3일정도 빨리 우화하였다.
