对受赤松毛虫为害与未受害油松的二年生针叶及用这两种油松的完整针叶饲养的赤松毛虫幼虫生长发育情况进行了测定分析，发现植株受害后针叶异亮氨酸酪氨酸、蛋氨酸、赖氨酸、含量增加，氨基酸总量及多数游离氨基酸含量下降；水溶性总糖、粗脂肪、单宁、生物碱含量及总糖／氨基酸比例上升；脂肪酸、酚类、萜烯、矿质元素均有较大幅度变化，用受害后油松针叶饲养的幼虫摄食量减少３３５％，死亡率升高１０％，产卵量减少。
The growth and development of biennial needles damaged by Pinus dendrolimi and Pinus tabulaeformis, and the adult Pinus densiflora larvae fed with the intact needles of Pinus tabulaeformis were determined. The results showed that the content of needle isoleucine tyrosine, Methionine and lysine, the content of amino acids and the content of most free amino acids decreased; the content of total soluble sugar, crude fat, tannin, alkaloid and total sugar / amino acid increased; fatty acids, phenols, terpenes, Significant changes in the elements were observed. The feeding amount of larvae fed on Pinus tabulaeformis and Pinus tabulaeformis decreased by 335% and the mortality rate increased by 10% and the fecundity decreased.
