| Enzymatic Conversion and Degradation of Sex Pheromones in Antennae of the Male Silkworm Moth Antheraea polyphemus  | | | | Abstract
| In living antennae of the male silkworm moth Antheraea polyphemus the pheromone com-pounds [6,7-3 H]-6,ll-hexadecadienyl acetate and [12,13-3 H]-10,12-hexadecadienol are enzymati-cally converted to their corresponding fatty alcohols, aldehydes, acids and long-chained fatty acid esters. In antennae of freshly hatched moths the 3 H-labeled pheromones are degraded at high rates to volatile polar metabolites. The half-life of the pheromone acetate is about 3 min. In dried antennae the pheromone acetate is merely hydrolyzed to the fatty alcohol. | | | |

| Enzymatic Conversion of Sex Pheromones in Olfactory Hairs of the Male Silkworm Moth Antheraea polyphemus | | | | Abstract
| The sex pheromone compound [6,7-3H]-6,ll-hexadecadienyl acetate is enzymatically converted to its corresponding fatty alcohol, aldehyde and acid in living and homogenized olfactory hairs and in other parts of the antennae of the male silk-moth Antheraea polyphemus. The pheromone is metabolized in vitro mainly in the inner hydrophilic compartments, but scarcely in the outer hydrophobic cuticle of the olfactory hairs. | | | |

| Metabolism of the Herbicide Bromoxynil in Hordeum vulgare and Stellaria media | | | | Abstract
| The metabolism of [3,5-14C]3,5-dibromo-4-hydroxybenzonitrile (bromoxynil) was studied in Hordeum vulgare and Stellaria media. In excised barley seedlings the time course of metabolism was followed over 48 h and the distribution of radioactivity to various metabolic fractions measured. The metabolites, sepa rated by TLC and HPLC, were identified by chemical and spectrometric methods. Bromo-hydroquinone and 2,6-dibromohydroquinone were found, indicating partly debromination and replacement of the nitrile group by hydroxyl. The major parts of bromoxynil and of the metabolites were recovered in glucosidic conjugates. In Stellaria media the same metabolites as in Hordeum vulgare were determined. Additional ly, metabolites of unknown structures without bromine were detected. | | | |
