Serricornin ((4S,6S,7S)-7-hydroxy-4,6-dimethyl-3-nonanone), a female sex pheromone component isolated from the cigarette beetle (Lasioderma serricorne F.), is widely used to control adult beetles. As a highly selective attractant, synthetic serricornin is often combined with food attractants or other pheromone components to form multi-component trapping systems. In tobacco storage environments, each trap can capture a large number of male beetles daily, significantly reducing population density. Compared to traditional monitoring methods, serricornin-based traps demonstrate significantly improved monitoring accuracy and control efficiency against cigarette beetles.
