The sex pheromone of the sand sagebrush carpenterworm, Holcocerus artemisiae (Lepidoptera, Cossidae).
(Z)-5-dodecen-1-ol (Z5-12:OH), (Z)-5-dodecenyl acetate (Z5-12:Ac), and (Z)-5-tetradecenyl acetate (Z5-14:Ac) were found in the extracts of the female sex pheromone gland of the carpenterworm moth Holcocerus artemisiae Chou et Hua, a pest of Artemisia filifolia. The average amounts of Z5-12:OH, Z5-12:Ac, and Z5-14:Ac in a single sex pheromone gland of a calling moth were (7.14 +/- 0.73) ng, (54.20 +/- 0.34) ng, and (38.70 +/- 0.46) ng, respectively. Electroantennography (EAG) of these compounds and their analogues demonstrated that Z5-12:Ac excitated the largest male EAG response, followed by Z5-14:Ac. Traps baited with rubber septa impregnated with Z5-12:Ac (500 microg/septum) and Z5-14:Ac (300 microg/septum) were more effective than traps with other baits or virgin females. Addition of Z5-12:OH to rubber septa did not enhance the trap catches, but (E,Z)-3,5-dodecadienyl acetate (E3,Z5-12:Ac) enhanced the trap catch.
