Terpene attractant candidates of Dioryctria sylvestrella in maritime pine (Pinus pinaster) oleoresin, needles, liber, and headspace samples

摘要: Capillary GC analysis was used to determine the proportion and quantity of terpenes in wood resin, pentane extracts from needles liber, headspace samples pruning wounds 24 thirteen-year-old maritime pine. Fifteen different were identified samples. Germacrene D β-pinene dominant terpenic compounds needles, while α-pinene liber resin. Headspace both contained essentially monoterpenes. Only trace amounts sesquiterpenes found wound emissions. The presence an oxygenated compound, linalool, emissions is discussed, although this compound not Maritime pine essential oil. Twelve trees studied infested by Dioryctria sylvestrella. susceptibility insect related terpene composition
