(Z,Z)-7,11-Hexadecadienal, specifically the (7Z,11E) isomer, is a key female sex pheromone component isolated from the tobacco cutworm moth Spodoptera litura. It is primarily used in agriculture for monitoring and controlling this major pest by formulating multi-component lures, often combined with compounds like Z9,E11-14:Ac. These pheromone traps significantly enhance male moth capture rates by 40-60% compared to conventional methods, providing efficient population surveillance and supporting targeted management strategies in crops like vegetables, cotton, and tobacco.
