摘　　要：本研究探讨了石榴果实的重要害虫井上蛀果斑螟Assara inouei饥饿胁迫下的能量代谢特点。结果发现,在饥饿胁迫下,井上蛀果斑螟幼虫的鲜质量、干质量及脂质、蛋白质、糖原、总糖含量均显著低于正常饲喂组,含水量和海藻糖含量显著高于正常饲喂组。随着饥饿时间延长,幼虫鲜质量和干质量均呈逐渐下降趋势,含水量在48 h后显著升高,脂质含量呈先降低后升高的变化趋势,蛋白质含量在48 h时显著升高后趋于平稳,糖原含量在72 h时显著降低,海藻糖和总糖含量均在24 h时最高,在36 h后显著降低且趋于平稳。井上蛀果斑螟幼虫对饥饿胁迫的应对与其体内水分、脂质、蛋白质和糖类的含量有相关性,该虫通过调整自身生化物质的变化以适应饥饿胁迫。The characteristics of energy metabolism of Assara inouei,an important pest of pomegranate fruit,were investigated under starvation stress.The results showed that under starvation stress,the fresh body weight,dry body weight,and the contents of lipids,proteins,glycogen and total sugars of A.inouei larvae were significantly lower than those of the normal feeding group,and the contents of water and trehalose were significantly higher than those of the normal feeding group.With the prolongation of starvation time,the fresh weight and dry weight of larvae gradually decreased,and the water content increased significantly after 48 h,the lipid content decreased first and then increased,the protein content decreased significantly at 48 h and then stabilized,the glycogen content decreased significantly at 72 h,and the trehalose and total sugar contents were the highest at 24 h,and then decreased significantly and became stable after 36 h.The response of the larvae to starvation stress was related to the contents of water,lipids,proteins and sugars of the body.The larvae adapted to starvation stress by adjusting the changes of biochemical substances.
