Abstract

솔나방(Dendrolimus spectabilis)의 變態에 따른 acid 및 alkaline phosphatase의 活性度의 變化를 測定하였다. 두 酵素의 活性度는 幼蟲의 成長과 더불어 增加하고 전용기에서 減少하였다. Acid phosphatase는 용기의 初에, 그리고 alkaline phosphatase는 幼蟲8齡에서 각각 最高의 活性을 나타내었다. 전용기에서 두 酵素간의 活性度의 차이는 크게 나타나지 않았으나 幼蟲8齡에서 보다는 훨씬 낮았다. Acid phosphatase의 活性度는 용기초에 增加하고 용기말에서 減少하다가 成蟲에서 다시 上昇하였다. Total phosphatase의 活性度의 變化는 變態에 따른 生理的曲線인 U字型 pattern을 나타내었다.

The activity of acid and alkaline phosphatases of pine moth, Dendrolimus spect abilis Butler was measured in a serier of developmental stages ranging from the larva to the adult. The activity of both enzymes increased gradually with age of larvae, and then decreased in the prepupal stage. Acid enzyme was at a maximum in the pupal early stage and alkaline enzyme in the 8th instar larva, respectively. And in the prepupal stage there were no significant differences between both acid and alkalnie phosphatases. However, their activities were far lower than in the 8th instar larva. In the pupal early stage there occurs a increase in the acitivity of acid enzyme followed by a decrease in the pupal later stage, and in the adult stage its activity increased again.
