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.

Notes: Calculations of the distribution of states in cell populations grown in well-mixed, isothermal batch and continuous flow reactors are presented. By restricting the analysis to a class of bacteria for which cell division control may be modeled using overlapping timers, analytical results are obtained for many cell population characteristics in terms of the growth rate history. This required growth rate trajectory is evaluated using a separate overall reactor model. The simulation results conform qualitatively to available experimental data and suggest new experiments for further testing of the single-cell model.
