Female-baited flight traps were used to monitor the prevalence of the navel orangeworm Amyelois transitella (Walker) in fig orchards for two growing seasons as a part of an effort to evaluate the efficacy of mating disruption. In the second season, additional areas were monitored to compare prevalence in Calimyrna figs, which have 1 crop per year, with that in Conadria and other varieties with 2 crops per year. Prevalence was similar between the Calimyrna figs and the other varieties examined. Temporal trends in untreated plots were similar between the two seasons and the varieties examined. Males were more prevalent at the beginning and end of the growing season. Mating disruption achieved trap shutdown and resulted in a significant reduction of fruit damage in the first year of the study.
