Identification of the primary female sex pheromone component of the mimosa webworm (Lepidoptera: Plutellidae)
Environmental Entomology 19 (1), 1-7
Abstract: E11-tetradecenyl acetate (E11-14:Ac) was identified as the primary female sex pheromone component of the mimosa webworm, Homadaula anisocentra Meyrick. Chemical analyses by gas chromatography and gas chromatography/ mass spectrometry of virgin female sex pheromone gland extracts indicated the presence of E11-14:Ac, E11-14: OH, and 14:Ac, whereas sex pheromone gland volatiles contained only E11-14:Ac and 14: Ac (at approximately 1% of E11-14:Ac). Gas chromatography-electroantennogram detector analyses indicated male antennal responsiveness to a component in pheromone gland extracts and volatiles that had an elution time coincident with E11-14:Ac. In field-trapping studies, E11-14:Ac elicited trap capture rates not different (P > 0.05) from those in traps baited with virgin females. Addition of either E11-14:OH or Z11-14:Ac reduced trap capture rates, whereas E- and Z11-14:Ald appeared to have no effect on trap capture rates.
