DESCRIPTION
WHO CAUSES IT?
Cydia pomonella, commonly known as the codling moth, is a lepidopteran insect belonging to the Tortricidae family. Adults are small, with a wingspan of approximately 18 mm, and have dark gray forewings with a characteristic brown spot near the edge. Females lay their eggs individually on the fruits or leaves of the grapefruit. These eggs are small, white and hatch after an incubation period of 6 to 10 days. The neonate larvae, white in color with a black head, penetrate the fruit to feed on the pulp and seeds, causing considerable damage. They go through five larval stages before emerging from the fruit, at which time they look for a suitable place to pupate, generally on the bark of trees or on the ground. This process culminates with the emergence of adults, thus completing their development. In warm climates, Cydia pomonella can produce two to three generations per year, increasing its ability to cause severe damage to grapefruit crops.
SYMPTOMS
Codworm causes significant damage to grapefruits, affecting both the quality and quantity of the harvest. The larvae pierce the fruits to feed, which results in the formation of tunnels and cavities filled with excrement and remains of pulp, thus reducing their commercial value.
- Small holes on the surface of the fruit.
- Presence of excrement and sawdust around the holes.
- Internal damage to the fruits, with visible tunnels.
- Premature fall of affected fruits.
- Reduction in the commercial value of the fruits.
- Greater susceptibility to secondary infections due to fungi and bacteria.

- Regularly monitor the crop with pheromone traps to detect the presence of adults.
- Release natural enemies such as Trichogramma spp. for biological pest control.
- Apply selective insecticides at critical moments of pest development.
- Maintain good field hygiene, eliminating fallen fruits and pruning remains.
- Use protective nets around trees to prevent oviposition.
- Promote the use of varieties that are resistant or less susceptible to infestation.
- Implement crop rotation to interrupt the pest development cycle.
- Use sexual confusion treatments with pheromones to reduce mating.
- Promote a favorable environment for natural predators by diversifying plants in the field.
- Avoid excessive use of insecticides to avoid damaging the pest's natural enemies.
