- Abstract
Extracts of the female sex pheromone gland of the carpenterworm moth, Holcocerus vicarius ( Walker) ( Lepidoptera: Cossidae), a pest of Ulmus pumila L. ( Ulmaceae), were found to contain Z7-tetradecenyl acetate ( Z7-14Ac), E3-tetradecenyl acetate ( E3-14Ac), ( Z3, E5)-tetradecenyl acetate ( Z3, E5-14Ac), and Z7-tetradecenyl alcohol ( Z7-14 OH) by coupled gas chromatographic-electroantennographic detection ( GC- EAD) and coupled gas chromatography-mass spectrometry ( GC- MS). Field trapping studies with impregnated rubber septa indicated that Z7-14Ac was essential for attraction of males of H. vicarius. However, the most attractive blend contained Z7-14Ac, E3-14Ac, Z3, E5-14Ac, and Z7-14 OH in a 50:22:17:10 ratio. Our results demonstrated that a blend of Z7-14Ac, E3-14Ac, Z3, E5-14Ac, and Z7-14 OH represented the sex pheromone of H. vicarius. The optimized four-component lure blend may be useful for monitoring H. vicarius infestations and mating disruption.
