Novel sex attractant compositions for the adult male pink bollworm or pinkspotted bollworm containing an unnatural ratio of Z,Z- and Z,E-isomers of 7,11-hexadecadien-1-ol acetate and use thereof are described. In the method of the invention, the novel unnatural attractant compositions are applied to fields treated with the Z,Z- or Z,E-isomer of 7,11-hexadecadien-1-ol acetate. This causes the preference of the males to be shifted away from the ratio of the isomers in the pheromone emitted by the female of the species and to the unnatural attractant compositions.
