Abstract

|
|
|
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.
