| 摘 要： | 从4个方面综述了我国松树诱导抗虫性研究进展，重点阐述了受害松针体内化学物质的变化，受害松针对松毛虫种群特征的影响以及松树诱导抗虫性的特性和影响因子等。已有的研究结果表明，受害后松针内化学物质有较大变化：一些营养物质(糖、氨基酸、蛋白质、脂肪酸等)的含量出现不同程度的降低，而体内的某些次生代谢物质(挥发性的和非挥发性的次生代谢物质)的含量呈上升趋势。这一抗性机制将使松毛虫的发育期延长、死亡率增加、生殖力减弱，从而进一步导致整个种群数量的下降。由此进一步分析了松毛虫周期性暴发的机理，旨在为松毛虫的综合治理提供理论参考。 |

| Abstract: | The recent progress in induced resistance of pines to Pine Caterpillar in China was reviewed in this paper. The four aspects including chemical change of the damaged pine needles, the effect of damaged pine needles on the population dynamic of Pine Caterpillar, the characteristics and influenced parameters of the induced resistance of pines to Pine Caterpillar were analyzed. The reported results suggested that the content of some nutrient substances(sugar, amino acid, protein, fatty acid et al .) were degradation, and the content of secondary metabolites (volatile and nonvolatile) were risen in the damaged pine. In turn, the longer growth period, higher mortality and lower fecundity were found in the Pine Caterpillar after fed in damaged pine. Furthermore, the mechanism of the periodic outbreak of Pine Caterpillar and its management were also discussed. |
