摘要
川硬皮肿腿蜂雌成蜂寄生其替代寄主后 ,糖原、海藻糖、还原糖等机体成分的含量和α -淀粉酶及海藻糖酶的活力发生了显著的变化。寄生后糖原 (1～ 6d)、海藻糖 (1～ 3d)含量显著下降 ,第 10天达最低值分别为 0 7190mg·g- 1 、1 384 4mg·g- 1 ,比寄生当天分别降低了 98 4 7%、92 2 1% ;同时 ,还原糖 (以葡萄糖为主 )总量则逐渐上升 ,第 10天达最高值 13 3416mg·g- 1 ,是寄生当天的 14 8倍。寄生后第 1～ 3天 ,α -淀粉酶、海藻糖酶等水解酶系的活力迅速上升 ,第 3天达最大值 ,分别为 82 5 816 μmol·g- 1 min- 1 、896 72 37μg·g- 1 min- 1 ,然后逐渐下降 ,到第 10天接近寄生当天的水平。本文还就替代寄主的糖代谢 。
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 4?mg·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 6?mg·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 6?μmol maltose·g -1 min -1 、896 723 7?μg 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.
