"codlin moth"的定义和意义

What is a "codlin moth"?

A codlin moth is a notable pest of apple and pear trees, causing damage to the fruit during its larval stage. This tiny moth species has a wingspan of approximately 1.5 to 2 centimeters and is typically grayish-brown. The adult moths emerge in the spring and lay eggs on the fruit or nearby leaves. Once hatched, the larvae tunnel into the fruit, feeding on the developing seeds and causing significant damage. Infestations by codling moths can lead to reduced fruit quality and yield.
