Defect data from figs taken from orchards at harvest show that, contrary to grower perceptions, the driedfruit beetle and other nitidulids are responsible for greater damage and economic loss to growers compared to the navel orangeworm. Data from prior years indicate that damage from the navel orangeworm can be reduced by placing traps in large portions of contiguous plantings over several weeks prior to fruit maturity, but that a small number of trees within a large planting cannot be selectively protected by traps left in place through the growing season including fruit maturity. The present research examines effects of pheromone dose and trap spacing, in an attempt to find cost-effective ways to implement this pest management technique.
