WHO CAUSES IT?
Tuta ABSOLUTA, commonly known as tomato moth, is a small moth native to South America that has managed to spread globally, seriously affecting horticultural crops. Its body is elongated, with gray and mottled wings, and a wingspan that does not exceed 10 mm. Adult females deposit eggs singly or in groups on leaves, stems and fruits. Larvae emerge from these eggs and quickly enter the plant tissues, where they remain for most of their development. These larvae go through four stages before pupating, making galleries inside the plant. Pupation can occur inside the plant or in the soil, protected by a cocoon. In warm conditions, the cycle is completed in just over three weeks, allowing for multiple generations per year. This high reproductive rate, together with its ability to develop hidden within the plant tissue, makes its control difficult and favors its rapid expansion.

SYMPTOMS
In Plants, Tuta ABSOLUTA causes a devastating disease, especially in tomato crops, although it also affects other solanaceous plants. The larvae pierce leaves, stems and fruits, compromising the physiology of the plant and drastically reducing yield. Internal larval damage prevents early detection, allowing the pathogen to multiply before being noticed. The commercial loss is not only due to direct damage, but also to the decrease in fruit quality and greater vulnerability to secondary infections.
- Sinuous galleries in leaves and stems
- Premature leaf drop due to internal damage
- Visible perforations in fruits with dark excrements
- Localized necrosis in the affected areas
- Dead or deformed terminal shoots
- Presence of whitish larvae inside the fruit or on leaves
- Significant reduction in commercial production

RECOMMENDATIONS
- Check your plants often, especially if you grow tomatoes
- Remove and destroy damaged leaves or fruits
- Use pheromone traps to attract and catch adults
- Place fine meshes in greenhouses or windows to prevent them from entering
- Keep the crop clean by eliminating plant debris after harvesting
- You can apply a solution of potassium soap and neem oil or garlic infusion if the infestation is mild.
- Place light traps or pheromone traps to catch the adults.
- In severe infections, use specific products
