| 摘 要： | 通过探讨松树受害后松针的一些化学物质变化与马尾松毛虫Dendrolimus punctatus 种群参数的相互作用关系。结果表明：松针被马尾松毛虫为害后，针叶的氨基酸含量减少、单宁和总酚含量增加；马尾松毛虫取食被害松针后，体内的2种解毒酶(过氧化氢酶、羧酸酯酶)活性增加，其种群参数表现出发育历期延长、体重减轻、死亡率增加、生殖力下降的变 化。

| Abstract: | The interaction between the changes of some chemicals (amino acids and secondary metabolites) in damaged pine needles and the population parameters of pine caterpillars, Dendrolimus punctatus Walker, was explored in this paper. The results showed that: (1) less amino acids and more tannins and phenolics were detected to change in pine needles after fed by pine caterpillar; (2) slower development, lighter weight, less fecundity, high mortality and higher activity of detoxification enzymes (peroxidase and carboxylesterase activity) were found in pine caterpillar population as fed on damaged pine needles. |
