Ecdytolopha aurantiana

Scientific name: Ecdytolopha aurantiana

Crop: citrus

Damage: Fruit drilling: the fruits affected turn yellow and drop. The hole for caterpillar penetration become evident and it is possible to observe secretions that harden and stick to fruit peel.

Behavior:

• The moths lay eggs mainly on the fruit surface.
• After the hatching of the eggs, the caterpillars penetrate into the fruits and feed on the pulp.
• After penetrating into the fruit, the Ecdytolopha aurantiana releases excrements and food waste to the outside of the fruit, hardening the peel.
• At the end of the larval period, the caterpillars abandon the fruits to pupate in the soil.

Control

End of caterpillar resistance!

Bacillus thuringiensis has different crystals in its composition: Cry1Aa, Cry1Ab, Cry1Ac, Cry2Aa, and Cry2Ab. This characteristic makes Bacillus thuringiensis an important tool for the management of the complex resistance system of caterpillars.
