WHO CAUSES IT?
Cacoecimorpha pronubana, commonly known as the cacoecia or carnation worm, is a lepidopteran belonging to the Tortricidae family. Adults are small brown moths with forewings characterized by dark transverse bands. Females lay eggs in groups on the surface of pear leaves. The eggs hatch into larvae that feed on leaf tissue, rolling up the leaves to create a protective shelter. The larvae go through five instars before reaching maturity, at which point they descend to the ground or seek refuge in the bark to pupate. The pupal phase lasts between two and four weeks, depending on environmental conditions, after which the adults emerge to start a new cycle. In temperate climate regions, Cacoecimorpha pronubana may have two to three generations per year, while in warmer climates, generations may increase to four.

SYMPTOMS
The infestation of Cacoecimorpha pronubana in the pear tree causes various damages that affect both the growth of the tree and the quality of the fruits. The larvae feed on foliage and young shoots, which can cause deformed leaves and stunted growth. In addition, the fruits can be attacked, presenting scars and dents that reduce their commercial value and storage capacity.
- Rolled and damaged leaves.
- Presence of larvae and excrement on the leaves.
- Deformations and delayed growth in new shoots.
- Scars and dents on the fruits.
- Premature fall of damaged fruits.
- Lower quality and size of the fruits.

Recommendations
- Regularly monitor trees for the presence of eggs, larvae or initial damage.
- Use pheromone traps to capture adults and reduce the pest population.
- Implement biological control programs through the introduction of specific parasitoids and natural predators of Cacoecimorpha pronubana.
- Apply insecticide treatments at critical times, especially during the first larval stages.
- Promote cultural practices such as pruning and elimination of affected parts to reduce the habitat of the larvae.
- Practice integrated pest management, combining biological, cultural and chemical methods to minimize the use of insecticides.
- Keep the garden clean and free of weeds that could serve as a refuge for the larvae.
- Promote biodiversity in the garden to increase the presence of natural enemies of the pest.
- Apply preventive treatments at times of highest risk of infestation, based on monitoring and environmental conditions.
