    Sex pheromone of the avocado pest,Amorbia cuneana (Walsingham) (Lepidoptera: Tortricidae) (1982)
    Springer
    Journal of chemical ecology 8 (1982), S. 255-265

    ISSN: 1573-1561

    Notes: Abstract The major volatile components in the extract of the female sex pheromone gland ofAmorbia cuneana consisted of (E,E)- and (E,Z)-10,12-tetradecadien-1-ol acetates. The identification was based on electroantennogram bioassay of gas Chromatographic effluent from sex pheromone gland extract, relative retention times on polar and nonpolar gas chromatographic columns, chemical degradation (ozonolysis, saponification), mass spectrometry, chemical synthetic methods, and field tests. Based on mass spectrometry and retention times by capillary gas chromatography, traces of (E)-10-tetradecen-1-ol acetate and 1-tetradecanol acetate were also present in the extract. Traps baited with a combination of synthetic (E,E)- and (E,Z)-10,12-tetradecadien-1-ol acetates caught more males than did traps baited with females.

    The use of algal assays and chlorophyll concentrations to determine fertility of water in small impoundments in West Virginia (1980)
    Springer
    Hydrobiologia 71 (1980), S. 19-34 
    Details
    ISSN: 1573-5117
    Keywords: Algal Assays ; Chlorophyll Concentrations ; Small Impoundments
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Seven small artificial lakes in West Virginia were sampled in the spring and fall. Water taken during these isothermal periods was used for the EPA Algal Assay with Selenastrum capricornutum as the test alga. In all cases the limiting nutrient was phosphorus. However in every case the water was fertile enough for the alga to grow well without the addition of nutrients. Each lake was sampled several times during the summer and nutrient analysis and chlorophyll concentrations indicated that each lake is probably eutrophic. These conclusions were borne out by the algal assays. The assays also indicated that there were probably no toxic elements in any of the seven lakes.
