摘　　要：通过对被松突圆蚧不同程度危害的马尾松针叶内主要营养物质的测定,表明受害马尾松针叶内总糖和可溶性糖含量随着危害程度的加重先降低后增加;氨基酸含量随着危害程度的加重而下降。研究表明,马尾松针叶内主要营养物质的含量与松突圆蚧的不同危害程度有显著的相关性。Based on the determination of the nutritious ingredients （soluble sugars and total sugars） in the damaged masson pine needles, the results indicated that the contents of total sugar and soluble sugar increased firstly and declined subsequendy as the damage degree increased. The contents of amino acids declined as the damage degree increased. In conclusion, the main nutritious ingredients in the needles of Pinus massoniana had significant correlation with different damage degree by Hemiberlesia pitysophila.
