3E, 5Z-Dodecadienyl Acetate

(3E,5Z)-3,5-Tetradecadienoic acid, isolated from female black carpet beetles (Attagenus megatoma), serves as a key sex pheromone component for controlling various dermestid pests, including the khapra beetle (Trogoderma granarium) and hide beetle (Dermestes maculatus). When combined with behavioral synergists, it forms multi-component lures that significantly reduce mating success in confined spaces (mating rates dropped from 70% in controls to 30% in treated groups).
