摘要: The effect of needle damage on the release rate Masson pine (Pinus massoniana Lamb.) volatiles was examined. Needles were continuously damaged by mechanical (MDP) or feeding caterpillar (Dendrolimus punctatus) larvae (LFP); undamaged used as a control (UDP). Volatiles collected before damage, and at 16, 24, 40, 48, 64, 72, 88 96 h post-damage, analyzed. analyses revealed that 19 compounds identified constitutive from UDP terpenes green leaf odors. MDP LFP higher than UDP. At emission returned to same level Some volatiles, including sabinene, ocimene, limonene-1,2-epoxide, linalool, linalool acetate, germacrene d-4-ol, farnesol, (E)-4,8-dimethyl-1,3,7-nonatriene induced and/or larval attack. Furthermore, MDP. Based an exact estimation proportion needles, significant linear correlation between total needles found in case but not
