The role of octenol as a mosquito attractant is still under investigation. When used alone, octenol has been a good attractant for only a few species. However, there appears to be a synergistic response of species of the genera Aedes, Anopheles, Coquillettidia, Psorophora, and Mansonia to the combination of octenol and CO2. Further research is required to determine the potential role of this compound in mosquito management programs.
