Answer

To solve the question regarding the period in between two moults of insects, let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that describes the period between two moults in insects. Moulting is a process where insects shed their exoskeleton to grow.

2. **Analyzing the Options**:
- **Option A: Stadium**: This term is often used to describe the period between two successive moults in insects.
- **Option B: Instar**: This term refers to the developmental stage of an insect between two moults, specifically focusing on the size and shape.
- **Option C: Incubation**: This term is related to the process of sitting on eggs to hatch them, which is not relevant to moulting.
- **Option D: None of the above**: This would imply that none of the provided options are correct.

3. **Identifying the Correct Term**: Based on the definitions:
- The term that specifically refers to the period between two moults is "stadium".
- "Instar" refers to the stage itself rather than the period between stages, and "incubation" is unrelated.

4. **Conclusion**: Therefore, the correct answer to the question is **Stadium** (Option A).

### Final Answer:
The period in between the two moults of insects is called **Stadium**.
