This method of cultural control requires regular scouting of solanaceous plant species, looking for signs of feeding damage. The caterpillars themselves can be hard to see against the green foliage of the host plant, so careful monitoring of defoliation or the presence of frass ( Figure 11) may be better indications of caterpillar presence.
