越冬代菜粉蝶 Pieris rapae蛹被蝶蛹金小蜂 Pteromalus puparum寄生后 ,其血淋巴中可溶性蛋白含量在寄生后 0 .5～ 2 d逐日上升 ,此后则逐日下降 .雌雄寄生蛹血淋巴中可溶性蛋白含量在寄生后 1～ 4 d显著高于同期未寄生蛹 ,寄生后 5d则略低于同期未寄生蛹 ;寄生蛹血淋巴中总糖和海藻糖含量的变化趋势与可溶性蛋白相同 ,也是寄生后 0 .5～ 2 d升高 ,寄生后 3～ 5d降低 .寄生后 0 .5～ 2 d,雌雄寄生蛹血淋巴中总糖和海藻糖含量显著高于同期未寄生蛹 ,寄生后 3～ 5d则恰好相反 .寄生蛹血淋巴中还原糖含量在寄生后 0 .5～ 3d日渐升高 ,寄生后 4 d维持在较高水平 ,而寄生后 5d则急剧下降 .越冬代菜粉蝶蛹血淋巴中海藻糖酶无活力 ,而雌雄寄生蛹血淋巴中海藻糖酶的活力在寄生后 0 .5d开始显现 ,此后逐日升高 ,至寄生后 5d已达 4 3.2 4～ 4 4 .2 7μg葡萄糖 .mg-1蛋白 .min-1
The parasitoid Pieris rapae pupae parasitized by Pteromalus puparum showed that the soluble protein content in the hemolymph increased day by day at 0.5-5 days after parasitization and then dropped day by day.The soluble protein The content of parasitized pupae was significantly higher than that of unpaired pupae 1 ~ 4 days after parasitization and non-parasitized pupae 5 days after parasitization. The changes of total sugar and trehalose content in hemolymph of parasitized pupae were the same as those of soluble protein, From 0.5 to 2 days, the parasitism decreased from 3 to 5 days, and at 0.5 to 2 days after parasitism, the contents of total sugar and trehalose in the hemolymph of male and female parasitoids were significantly higher than those of unpaired pupal parasites at 3 and 5 days after parasitism The opposite is true.The content of reducing sugar in parasitoid pupae increased gradually from 0 to 5 days after parasitization, maintained at a high level on the 4th day after parasitism, and decreased sharply on the 5th day after parasitism Trehalase was inactive, while the activity of trehalase in the hemolymph of male and female parasitoids was found at 0. 5 days after parasitism, and then increased from day to day, reaching 4 3.2 4 ~ 4 4 .7 7 μg of glucose at 5 days after parasitism -1 protein.
