Salt Marsh Caterpillar (Tiger moth)
Development of the Problem - Tiger moth caterpillars are frequently abundant in weeds growing near strawberry fields. Consequently, these larvae may be most numerous on border rows and near ditch banks. Adult tiger moths lay their eggs in masses of up to 100 eggs. When an egg mass has been laid on a strawberry plant, that and adjacent plants may be fully defoliated.
Control - Applied controls are rarely required for this infrequent pest.
1. Control weeds along ditch banks and field margins.
2. Scout field portions near ditch banks and perimeters, then spot-treat infested areas with recommended insecticides.
