The disruption effect of Z11-14: Ac on Pandemis heparana was evaluated in the laboratory. The mating percentage without the chemical was 85%. When 100ng of Z11-14: Ac was used as a disruptant, the mating percentage fell to 24%. Moreover, when 1, 000ng and 10, 000ng were used, the mating percentage was less than 5%. This result indicates that Z11-14: Ac causes mating disruption in P. heparana. This laboratory bioassay method was effective to estimate mating disruption effect.
