Locomotor centre of the body of an insect is

Options

A. Brain
B. Head
C. Thorax
D. Abdomen

Answer

### Step-by-Step Solution:

1. **Understanding Insect Morphology**: Insects have a body divided into three main regions: the head, thorax, and abdomen. Each of these regions has specific functions and structures.

2. **Identifying the Regions**:
- **Head**: Contains sensory organs and mouthparts but does not play a role in locomotion.
- **Thorax**: This is the region responsible for locomotion. It consists of three parts: prothorax, mesothorax, and metathorax.
- **Abdomen**: Contains internal organs and systems but is not involved in locomotion.

3. **Locomotor Center**: The locomotor center is the part of the body that facilitates movement. In insects, this is primarily located in the thorax, where the legs and wings are attached.

4. **Wings and Movement**: The wings, which are essential for flight, arise from the thorax. The first pair of wings comes from the mesothorax, and the second pair comes from the metathorax.

5. **Evaluating the Options**:
- **Brain**: Incorrect, as it does not control locomotion directly.
- **Head**: Incorrect, as it does not have locomotor functions.
- **Thorax**: Correct, as it is the region where locomotion occurs due to the presence of legs and wings.
- **Abdomen**: Incorrect, as it is not involved in locomotion.

6. **Conclusion**: The correct answer to the question "Locomotor centre of the body of an insect is" is the **thorax**.

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