Used primarily as a pheromone in pest control, (E)-11-Hexadecenal plays a key role in disrupting the mating behavior of certain insect species, especially the cotton boll weevil. It is incorporated into lures and traps to monitor pest populations in agricultural settings. This compound helps reduce reliance on conventional insecticides by enabling targeted, environmentally friendly management strategies. Its application is most effective in integrated pest management (IPM) programs for cotton crops, where it aids in early detection and population suppression.
