中文摘要：

在3℃条件下，对越冬代异色瓢虫[Harmonia axyridis （Pall）]雌、雄虫不同冷藏时间（0，30，60，90，120，150 d）的糖、蛋白质、脂肪、含水量等生理生化指标进行了测定。结果表明：冷藏期间，含糖量随冷藏时间的增加而降低，各冷藏时间之间的含糖量差异显著，冷藏0 d雌雄成虫的含糖量最高，分别达40？00μg／mg和43？69μg／mg；整个冷藏期间雌虫蛋白质含量显著高于冷藏0 d的蛋白质含量；整个冷藏期间雄虫蛋白质含量与冷藏0d的蛋白质含量差异不显著；脂肪含量随冷藏时间的增加而降低，各冷藏时间之间的脂肪含量差异显著，冷藏0 d雌、雄成虫的脂肪含量最高，分别达475？87μg／mg和450？67μg／mg；含水量随冷藏时间的增加而降低，但差异不显著。

英文摘要：

Physiological and biochemical indexes, including total sugar, protein, fat and water con？tent, of overwintering H. axyridis kept under 3 ℃ for different storage time （ 0, 30, 60, 90, 120 and 150 d） were determined. The results showed that sugar content of female or male ladybeetles significantly decreased with the increase of storage time, and there were significant differences be？tween sugar content of different storage time. The male and female adults had the highest sugar con？tent on 0 d, up to 40？00 μg/mg and 43？69 μg/mg, respectively. Protein content of female in the whole storage time was significantly higher than stored at 0 d. There were no significant differences in protein content of male in the whole storage time. Fat content of female or male ladybeetles signifi？cantly decreased with the increase of storage time. The female and male adults had the highest fat content on 0 d, up to 475？87 μg/mg and 450？67 μg/mg, respectively. Water content of female or male lady beetles decreased with the increase of storage time, but there were no significant differ？ences.
