Only larval stages of artichoke plume moth are damaging to mainly artichoke plants. Larvae of artichoke plume moth feed on almost all the plant parts including crowns in the soil, growing shoots and floral buds but their damage is considered very significant when they destroy floral buds.
Females of artichoke plume moth generally lay eggs on the lower surface of leaves. Eggs hatch into small larvae that burrow into leaf veins and then move internally toward petiole. While feeding, larvae develop through 4- 5 instars and mature. Mature larvae then exit the tunnel and drop on the soil surface and pupate in leaf litter. Under favourable conditions, artichoke plume moths can complete 1- 4 generations in a year.
