SEX-PHEROMONE COMPONENTS OF THE SUNFLOWER MOTH, HOMOEOSOMA-ELECTELLUM (LEPIDOPTERA, PYRALIDAE) - Z-9, E-12-TETRADECADIENOL AND Z-9-TETRADECENOL

An abdominal tip extract and a solution of the volatile emissions from female Homoeosoma electellum (Hulst.) moths were separately fractionated by gas chromatography and found to contain a single fraction having major stimulatory activity on male antennae. Further fractionation yielded three 14-carbon alcohols. These were identified as tetradecanol, Z-9- tetradecenol and Z-9,E-12-tetradecadienol, based on GC retention times on packed and capillary columns, mass spectral analysis and an EAG profile of isomeric tetradecenols. In a preliminary Field test traps containingZ-9,E-l 2-tetradecadienol and Z9-tetradecenol were as attractive to males as were female baited traps. © 1979 Entomological Society of America.
