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.

Key words: Pine, Induced resistance, Chemical change, Population dynamic
