Sex pheromone components of an undescribed Choristoneura species (Lepidoptera: Tortricidae) on lodgepole pine in British Columbia
AbstractE11-tetradecenyl acetate (E11-14 OAc) and Z11-tetradecenyl acetate (Z11-14 OAc) are sex pheromone components of an undescribed, pine-feeding Choristoneura (C. n. sp. CPG=Prince George) in British Columbia. Compounds were identified by coupled gas chromatographic- electroantennographic (GC-EAD) and coupled gas chromatographic-mass spectroscopic (GC-MS) analyses, and were field tested near Prince George, B.C. A 65:35 blend of E11-14 OAc and Z11-14 OAc attracted as many male C. n. sp. CPG as did the most attractive virgin fema1es, suggesting that the natural sex pheromone has only two significant components. This two-component blend is suggested for detecting and monitoring C. n. sp. CPG populations.
