C. Thorax
D. Abdomen

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Insects**: Insects, such as cockroaches, have their bodies divided into three main parts: the head, thorax, and abdomen. Each part has distinct functions and structures.

2. **Identifying the Parts**:
- **Head**: Contains sensory organs and mouthparts.
- **Thorax**: This is the central part of the insect's body and is crucial for locomotion.
- **Abdomen**: Contains organs for digestion, excretion, and reproduction.

3. **Locomotor Center**: The thorax is identified as the locomotor center of the insect. This is because it houses the muscles that control movement, including the legs and wings.

4. **Functions of the Thorax**: The thorax consists of three segments (prothorax, mesothorax, and metathorax) and is responsible for the movement of the insect. The legs and wings are attached here, allowing for locomotion.

5. **Conclusion**: Thus, the locomotor center of the body of an insect is located in the thorax.

**Final Answer**: The locomotor centre of the body of an insect is the **thorax**.
