Explanation

The codling moth (Cydia pomonella) is a major pest of apples and pears, but it is most famously associated with apples. However, in many agricultural contexts, especially in Pakistan, the codling moth is primarily known as a pest of apples. Wait, let me double-check. Actually, the codling moth is indeed a major pest of apples (and pears), but the question might be referring to a specific context. In general entomology, Codling moth is most notorious for apples. However, some sources might link it to grapes? No, that's not right. Let me verify: Codling moth larvae bore into apples and pears. It is not typically a pest of peaches or grapes. Between Apple and Pear, Apple is the primary host. So A is correct. But wait, the question says 'Coding moth' which is likely a typo for 'Codling moth'. Codling moth is indeed a major pest of apples. Therefore, the current answer A is correct.
