Abstract

Carborhydrate contents were compared between diapausing and non-diapausing pupae of the fall webworm, Hyphantria cunea DRURY. Glycogen content in the whole body of diapausing pupae kept at $-5{\pm}1^{\circ}C$ was less than that of those left at room temperature, while the amounts of trehalose and sorbitol showed the reverse trend. The osmotic pressure of haemolymph was higher in diapausing pupae than that in non-diapausing pupae. The mean oxygen consumption rate of diapausing pupae was $4{\sim}6.7$ times less than that of non-diapausing, normal pupae.

흰불나방의 휴면용과 비휴면용에서 탄수화물 함량을 비교하였다. 1. 저온상태($-5{\pm}1^{\circ}C$)에 보관한 휴면용은 실온에 둔 것 보다 글리코겐(glycogen)함량은 적었지만 트레할로스(trehalose)와 솔비톨(sorbitol)의 양은 많았다. 2. 휴면용에서 혈액의 삼투압은 비휴면용의 것 보다 높게 나타났다. 3. 휴면용의 평균 산소 소비량은 비휴면용 보다 $4{\sim}6.7$배 적었다.
