(abbr. Z9,E11-14:Ac) Spodoptera littoralis and S. litura mating attractant and mating inhibitor. Female pheromone, lures males. Used by McVeigh and Bettany 1986 and Downham et al., 1995 over the course of three years in a 99:1 with . Although they achieved good mating disruption this did not result in lower egg mass or population. The results of Campion et al., 1980 suggest that may be due to the need for other, minor female volatiles. Martinez et al., 1993 study control of its synthesis in S. littoralis by hormones, finding that the reduction step may be controlled by pheromone biosynthesis activating neuropeptide.
