(Z,Z)-7,11-Hexadecadienal serves as the primary female sex pheromone component of the pink bollworm (Pectinophora gossypiella). This highly specific attractant is typically blended with (Z,E)-4,11-tetradecadienyl acetate to create a lure mixture for monitoring and trapping male pink bollworm moths in cotton fields. Deploying these traps achieves daily catches of 15-30 males per trap, enhancing monitoring accuracy by over 50% compared to conventional methods.
