Solanaceous plume moth

The Solanaceous plume moth (Stenoptilodes taprobanes) is a lepidopteran pest belonging to the Pterophoridae family. It is recognized as a significant threat to various agricultural crops, particularly in warm climate zones where it can complete multiple generations annually.

This moth primarily targets species within the Solanaceae family. Key host plants include tomatoes, eggplants, and potatoes. Its presence is often underestimated due to the concealed behavior of the larvae, which feed within plant tissues, remaining hidden from standard visual inspections for extended periods.

The life cycle follows a holometabolous development path: egg, larva, pupa, and adult. The females typically deposit their eggs on the foliage or near flower buds. Upon hatching, the larvae quickly bore into stems or fruits, establishing a protected environment where they feed and grow.

Damage caused by this pest is primarily internal. By tunneling into the stems and fruits, larvae interrupt the transport of nutrients and water, which causes wilting, stunted growth, and premature fruit drop. Secondary infections by pathogens often follow, leading to rotting of the affected produce.

• Removal and destruction of crop residues after harvest to reduce overwintering populations.
• Implementation of pheromone trapping to monitor population dynamics and timing of control measures.
• Encouragement of natural enemies and parasitoids within the field.
• Targeted application of insecticides during the early larval stage to minimize crop damage.
