摘　　要：【目的】为了探究温度胁迫对舞毒蛾Lymantira dispar幼虫营养成分和总抗氧化力的影响。【方法】测定了不同温度(15、20、25、30、35、40℃)下处理3 h的舞毒蛾幼虫可溶性蛋白、碳水化合物、海藻糖、脂质含量以及总抗氧化力,以饲养温度25℃的舞毒蛾幼虫为对照。【结果】舞毒蛾幼虫在不同温度下可溶性蛋白含量变化无显著差异;碳水化合物与海藻糖含量均随着温度的升高,呈现逐渐下降趋势;脂质含量无论处理温度低于还是高于对照温度均会增加;而舞毒蛾幼虫总抗氧化力在经不同温度处理后均显著降低。【结论】温度变化可以显著影响舞毒蛾幼虫碳水化合物、海藻糖、脂质3种营养成分含量以及舞毒蛾幼虫的总抗氧化力的能力,而对舞毒蛾幼虫可溶性蛋白含量无显著影响。本研究对舞毒蛾幼虫的耐热性及其在不同温度下的防治具有指导意义。[Objectives] To investigate the effects of temperature stress on the nutrient composition and total antioxidant capacity of gypsy moth(Lymantria dispar) larvae.[Methods] The soluble protein, carbohydrate and trehalose content of gypsy moth larvae kept at different temperatures(15, 20, 25, 30, 35, 40 ℃) for 3 h were measured. Lipid content and total antioxidant capacity were compared with those of gypsy moth larvae kept at a temperature of 25 ℃.[Results] Temperature had no significant effect on the soluble protein content of gypsy moth larvae but their carbohydrate and trehalose content tended to decrease with temperature. Lipid content increased irrespective of whether the ambient temperature was lower, or higher, than the control. The total antioxidant activity of larvae was significantly affected by temperature.[Conclusion]Temperature can significantly affect the carbohydrate, trehalose and lipid content of gipsy moth larvae, and their total antioxidant activity, but has no significant effect on their soluble protein content. These results contribute to understanding the heat resistance of gypsy moth larvae and the control of this pest at different temperatures.
