Diagnostic characters

State Size Features

Larva 50 mm 5 pairs of false abdominal legs, cream color with black spots scattered throughout the body.

Adult 50 mm (wingspan) Wings with two shades of brown, the later ones being cream.

Phenological cycle

The adults appear in October, they mate and the female makes the laying on the plant. Egg hatching occurs in a very gradual manner, from December to almost April, depending on the temperatures recorded in each zone. The larvae begin to feed on the leaves to then penetrate the central nerve towards the stem, where, after completing the last larval stage, they pupate (in summer). Then the adults appear, thus closing the cycle.

Annual generations

Symptoms / Damage

Galleries in the interior of the plant (leaf nerve, stem base, inflorescences) subtracting vigor, even producing death.

Remains of excrement in the armpits of the leaves.

Control

- Chemical

Moment:

When the first eggs begin to hatch and before the larvae penetrate inside the plant. Once inside, the chemical treatment is of no effectiveness, given that the pesticide does not manage to come into contact with the insect. Applications will be made from the beginning to the end of the hatching period. After this time the treatments are not recommended because they are of no use.

- Ecological

- Cultural measures

It is recommended, whenever possible, to adjust the treatment just after cutting the artichoke in order to avoid waste problems.

Destroy the affected plants in summer.
