Tomatoes can be attacked by this pest at all stages of development. These situations can result in the loss of the entire product if not managed properly. Tuta absolute damages the leaves, stems, flowers, hill shoots, green and ripe fruits of the plant. The larvae open crooked paths in the mentioned parts. Initially, the larvae that feed between the leaf epidermis have necrotic spots. Then it enters the fruit and begins to feed on it, starts to damage the fruit.
The larvae of the pest creates spots by mining the leaves. One and two-year-old larvae feed on leaf mesophylls and open spot-like sewers on the leaves. This causes the leaf to dry out. Various infections weaken the photosynthetic activity of the plant, which weakens the plant. (bighaat picture)
In plants, holes are formed where larvae enter and exit. Also, there are abnormal fruit forms. These holes and dried pest secretion (a fine powdery material that plant-eating insects pass as waste after digesting plant parts) are the main characteristics of moths. Finally, the crooked pathways opened by tuta absolut in the fruit result in pathogens entering and rotting the fruit. (bighaat picture)
