Gas chromatographic analysis of the volatile terpenes of the wood oleoresin of maritime pines showed that the relative proportions of terpenes within the same tree did not vary according to sampling height and date. Pruning and tree vigor did not affect terpene profiles, but oleoresin composition varied widely from tree to tree. The trees attacked byDioryctria sylvestrella contained a significantly higher percentage of limonene, longipinene, and copaene, and a discriminant analysis, using the relative percentage of six terpenes, significantly separated infested and uninfested trees. The olfactory sensitivity of adult moths to a series of 20 volatile chemicals, including maritime pine oleoresin components, was evaluated with the electroantennogram method. Both sexes were sensitive to monoterpenes, oxygenated terpenoid compounds, and oleoresin samples. The use of terpenes as host attractants and biochemical markers for resistance toD. sylvestrella is discussed.
对马尾松木材油树脂的挥发性萜烯进行气相色谱分析表明，同一棵树上萜烯的相对比例不因采样高度和日期而变化。修剪和树木活力不会影响萜烯图谱，但油树脂的组成在不同的树之间差异很大。受 Dioryctria sylvestrella 侵害的树木含有更高比例的柠檬烯、长叶烯和石竹烯，使用六种萜烯的相对百分比进行判别分析，可以显著区分受侵害和未受侵害的树木。利用触角电位法评估了成年飞蛾对一系列 20 种挥发性化学物质（包括马尾松油树脂成分）的嗅觉敏感性。雌雄两性均对单萜、含氧萜类化合物和油树脂样品敏感。讨论了萜烯作为寄主引诱剂和对 Dioryctria sylvestrella 抗性的生化标志物的用途。
