The endocrine gland of insect which secrete the juvenile hormone is

Options

A. Corpora allata
B. Prothoraic Gland
C. Corpora cardiaca
D. None of the above

Answer

### Step-by-Step Solution:

1. **Identify the Question**: The question asks for the specific endocrine gland in insects that secretes the juvenile hormone.

2. **Understand the Role of Juvenile Hormone**: The juvenile hormone is crucial in the process of metamorphosis in insects. It regulates the development stages, ensuring that the insect remains in its larval form and does not prematurely transform into an adult.

3. **Identify the Gland**: The gland responsible for producing the juvenile hormone is known as the **corpora allata**. This gland plays a significant role in the hormonal regulation of growth and development in insects.

4. **Differentiate from Other Glands**: It is important to note that there are other glands in insects, such as the prothoracic gland, which secretes ecdysteroids that are involved in molting. However, the gland specifically responsible for the juvenile hormone is the corpora allata.

5. **Conclude the Answer**: Therefore, the endocrine gland of insects that secretes the juvenile hormone is the **corpora allata**.

### Final Answer:
The endocrine gland of insects which secretes the juvenile hormone is the **corpora allata**.
