2-Acetoxytridecane is a sex pheromone component isolated from the pea midge (Contarinia pisi) and fruit fly (Drosophila mulleri), with its (S)-enantiomer playing a critical role in insect mating behavior. In pest management, it is typically mixed with other diacetate compounds (e.g., (2S,11S)-diacetoxytridecane and (2S,12S)-diacetoxytridecane) in specific ratios to form multi-component lures for monitoring and trapping male pea midges.
