| Abstract: | (Z)-11-Hexadecen-1-ol acetate (Z11–16 Ac) free of theE isomer (<1%), hexadecan-1-ol acetate (16 Ac), and a hexadecen-1-ol the (Z)-11 isomer based on the retention time on a Carbowax capillary column] were identified in extracts of the sex pheromone glands of adult virgin female armyworms,Pseudaletia unipuncta. Also, gas Chromatographic retention times on polar and nonpolar columns indicated the possible presence of (Z)-9-hexadecen-1-ol acetate (Z9–16Ac). The ratioZ11–16Ac/16Ac/Z11–16OH/Z9–16Ac was 10.150.130.02. Infield testsZ11–16 Ac was attractive alone, and the addition ofZ9–16Ac,Zll–16 OH, or 16 Ac singly or in combination in ratios found in the gland did not increase trap capture.Mention of a proprietary product does not constitute an endorsement of this product by the USDA. |
