Answer

**Step-by-Step Solution:**

1. **Understanding the Alimentary Canal of Periplaneta (Cockroach)**:
- The alimentary canal of a cockroach is divided into three main parts: the foregut, midgut, and hindgut.

2. **Identifying the Structures**:
- The food intake begins at the mouth and passes through several structures:
- **Pharynx**: The initial part where food is taken in.
- **Oesophagus**: A narrow passage that connects the pharynx to the next structure.

3. **Identifying the Storage Structure**:
- After the oesophagus, the food moves into the **crop**.
- The crop is specifically designed for the storage of food before it moves to the next part of the digestive system.

4. **Understanding the Function of the Gizzard**:
- Following the crop, the food enters the **gizzard** (also known as the proventriculus), which is responsible for grinding and churning the food due to its muscular structure and chitinous plates.

5. **Conclusion**:
- The structure associated with the storage of food in the alimentary canal of Periplaneta is the **crop**.

**Final Answer**: The structure associated with storage of food in the alimentary canal of Periplaneta is the **crop**.
