(Z,Z)-11,13-Hexadecadienyl acetate serves as a key sex pheromone component in species like the pine processionary moth (Thaumetopoea pityocampa). It is synthetically produced for use in pest management strategies, specifically in lures and mating disruptors. By disrupting mating communication, this compound effectively reduces reproduction rates in pests such as the mulberry pyralid (Glyphodes pyloalis) and diamondback moth (Plutella xylostella), offering an eco-friendly alternative to chemical pesticides.
