Chauliognathus fallax Germar 1824 (Coleoptera: Cantharidae) occurs in North and South America and Australia. Gas chromatographic (GC) analyses of volatiles released by adults showed the presence of a male specific compound. GC coupled with electroantennographic detection (GC-EAD) showed that this compound is exclusively bioactive on female antennae, suggesting it to be a sex pheromone. GC coupled with mass spectrometry (GC-MS) and Fourier transform infrared spectroscopy (GC-FTIR), as well as dimethyl disulfide (DMDS) derivatization and hydrogenation, suggested the target compound to be (Z)-tricos-11-ene. Unambiguous structural proof was achieved by independent synthesis, whereas the biological significance of the compound as a sex pheromone was confirmed by field bioassays.
DEGRADATION OF POLYCYCLIC AROMATIC HYDROCARBONS TO RENDER THEM AVAILABLE FOR BIODEGRADATION

Page/Page column 5-8; 15-16, (2008/12/07)
A method for the degradation of polycyclic aromatic compounds is disclosed that involves dissolving ozone in a bipolar solvent comprising a non-polar solvent in which is of sufficiently non-polar character to solubilized the polycyclic aromatic compounds, and a polar-water-compatible solvent which is fully miscible with the non-polar solvent to form a single phase with the non-polar solvent. The bipolar solvent with dissolved ozone is contacted with the polycyclic aromatic compounds to solubilize the polycyclic aromatic compounds and react the dissolved polycyclic aromatic compounds with the ozone to degrade the dissolved polycyclic aromatic compounds to oxygenated intermediates. The bipolar solvent is then mixed with sufficient water to form separate non-polar and polar phases, the non-polar phase comprising the non-polar solvent and the polar phase comprising the non-polar solvent and the oxygenated intermediates. The polar phase is then diluted and incubated with bacteria to biodegrade the oxygenated intermediates.
