Gas chromatographic analyses of the female sex pheromone glands of Heliothis virescens (Fabricius 1777) from 3 locations (Mississippi, Virgin Islands, California) indicate that they all contain, at a minimum, the 4 components determined here to be important in the sex pheromone blend: (Z)-I I-hexadecenal, (Z)-9-tetradecenal, hexadecanal and (Z)-I I-hexadecen-l -01. There are no statistically significant strain differences with regard to these components. Females from California do not contain any (Z)-7- or (Z)-9- hexadecenal (lower limit of detection ca 0.1 ng/9), found in the other strains. In laboratory tests, moths from the 3 regions mate successfully when paired in reciprocal crosses.
