Abstract

Abstract:

The content of glycogen and trehalose, the activity of α amylase and trehalase changed remarkably after the alternative host parasitized by Scleroderma sichuanensis. The content of glycogen (1st-6th day) and trehalose decreased sharply on the 3rd to 6th day and got their minimum 0.719 0 mg·g^-1 and 1.384 4mg·g^-1 on the 10th day after parasitization, decreased by 98.47% and 92.21% respectively compaired with that of the 1st day. At the same time reducing sugar increased step by step, then got its maximum 13.341 6mg·g^-1 on the 10th day, 14.8 times that of the 1st day's. The activity of α amylase and trehalase elevated rapidly on the 1st to 3rd day. They got their maximum 82.581 6μmol maltose·g^-1min^-1、896.723 7μg glucose·g^-1 min^-1 on the 3rd day, then descended slowly to the level of the 1st day. Discussions were given to the sugar metabolism of the substitute host and the action of the parasite venom.
