DESCRIPTION
WHO CAUSES IT?
Cydia pomonella, known as the carpocapsa or pear moth, is a lepidopteran belonging to the family Tortricidae. The adult female lays her eggs individually on the leaves and fruits of the pear tree. The eggs hatch into larvae that pierce the skin of the fruits and feed on the inside, creating galleries in the pulp. After several weeks, the mature larvae leave the fruit to pupate in the bark of the tree or in nearby soil. The pupation phase lasts approximately two weeks, depending on environmental conditions. The adults emerge and restart the cycle. In temperate climates, codling moth can have two to three generations per year, while in warmer climates it can have up to four generations.
SYMPTOMS
The infestation of Cydia pomonella in the pear tree causes severe damage to both the quantity and quality of the fruits, decreasing their commercial value. The larvae that feed inside the fruits cause their premature fall, in addition to facilitating the entry of secondary pathogens that cause rot. Affected fruits have a less attractive appearance and are more susceptible to rotting during storage.
- Small entrance holes in the skin of the fruit.
- Internal galleries full of larva excrement.
- Premature fall of infested fruits.
- Internal rot of the fruit.
- Presence of larvae inside the fruit.
- Reduction in the size and quality of the fruit.

- Carry out regular monitoring of trees to detect the presence of eggs, larvae or initial damage.
- Use pheromone traps to monitor and capture adult males, helping to reduce the population and predict flight peaks.
- Implement biological control programs through the release of specific codling parasitoids.
- Apply insecticide treatments at critical moments in the pest cycle, such as when larvae emerge.
- Practice integrated pest management combining biological, cultural and chemical methods to reduce dependence on insecticides.
- Remove and destroy fallen and affected fruits to reduce the number of larvae that can complete their development.
- Promote biodiversity in the orchard to encourage the presence of natural predators of the codling moth.
- Use ground covers or mulch to make it difficult for larvae to reach the ground to pupate.
- Implement sexual confusion techniques to reduce adult mating.
