Abstract
The gland titer and release of sex pheromone was studied in individual Cydia pomonella females. An increase of the main compound (E,E)-8, 10-dodecadien-1-ol (codlemone) from 5.5 to 9 ng/gland, during the first 2 hr of calling, matched an increase in the release rate from 5 to 7 ng/hr/female. The average proportion of the minor compounds dodecan-1-ol, (E)-9-dodecen-1-ol, and tetradecan-1-ol in the effluvium decreased within 2 hr from 59% to 33%. Their proportion in the gland peaked 1 hr before the onset of the scotophase at 78% and decreased to 16% at 2 hr after onset of calling. Addition of these minor components to codlemone did not increase male attraction to field traps.
