The function of ecdysone hormone in insect is

Options

A. The growth and development of larva
B. The maturation into adult and laying eggs
C. To carry moulting in larval stage to form pupa
D. The secretion of cuticle in adult

Answer

### Step-by-Step Solution:

1. **Understanding Ecdysone**: Ecdysone is a hormone secreted by the prothoracic gland in insects. It plays a crucial role in the life cycle of insects, particularly during the process of metamorphosis.

2. **Metamorphosis Process**: Metamorphosis is the transformation process that insects undergo, where they change from larva to pupa and eventually to an adult. This process involves several stages and is essential for the development of insects.

3. **Role of Ecdysone**: Ecdysone regulates the process of molting, which is also referred to as ecdysis. During molting, the insect sheds its old exoskeleton to allow for growth and development.

4. **Stages of Development**: In the larval stage, ecdysone triggers the molting process, allowing the larva to grow and eventually transform into a pupa. This is a critical step in the metamorphosis process.

5. **Conclusion**: Therefore, the primary function of ecdysone in insects is to carry out molting in the larval stage, facilitating the transition to the pupal stage.

### Final Answer:
The function of ecdysone hormone in insects is to carry molting in the larval stage to form a pupa.
