Cydia pomonella

Codling moth

Description

Cydia pomonella, commonly known as the codling moth, is a pest insect that infests apple, pear, and walnut trees. It is found in many parts of the world and is a major pest of apple orchards. The larvae of the codling moth tunnel into the fruit, causing damage and making the fruit unmarketable.The adult codling moth is a grayish-brown moth with distinctive coppery patches on its wings. The moth is active at night and lays its eggs on the fruit or leaves of the tree. The eggs hatch into larvae that feed on the fruit. The larvae eventually emerge from the fruit and pupate in the soil. It can have 2-3 generations in warmer regions, when the he entire third generation overwinter as larvae. Control of the codling moth is important in apple orchards to maintain high-quality fruit production. A variety of methods are used to control the pest, including insecticides, mating disruption, and biological control agents such as parasitic wasps. Integrated pest management practices are often used to reduce the reliance on insecticides and minimize the impact on the environment. Overall, the codling moth is a significant pest of fruit trees and requires careful management to prevent economic losses.

Symptom

The larvae feed on the seeds and pulp of the apple, causing internal damage that is not visible on the surface. This can lead to the development of rot and mold, making the apple unsuitable for consumption or sale. Masses of frass can be presnet on the surface of the fruit. In addition to the direct damage caused by the larvae feeding on the fruit, the codling moth also creates entry points for other pests and diseases to infect the tree. This can further impact the health and productivity of the apple tree.
