Which cells secretes wax located at the outer surface of body wall ?

Options

A. Trophocytes
B. Oenocytes
C. Trichogen
D. Mycetocytes

Answer

To solve the question, "Which cells secrete wax located at the outer surface of the body wall?" we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking about specific cells that are responsible for secreting wax on the outer surface of an insect's body wall.

2. **Identify the Options**: The options provided are:
- Trophocytes
- Enocytes
- Trichogen
- Mycetocytes

3. **Analyze Each Option**:
- **Trophocytes**: These cells are known for storing reserve food for the insect. They do not secrete wax. Therefore, this option is incorrect.
- **Enocytes**: These cells are responsible for lipid detoxification and are known to secrete wax on the outer surface of the body wall. This option seems promising.
- **Trichogen**: These cells are involved in the production of cuticular hair in some insects. They do not secrete wax, making this option incorrect.
- **Mycetocytes**: These cells contain symbiotic bacteria and are not involved in wax secretion. Thus, this option is also incorrect.

4. **Determine the Correct Answer**: Based on the analysis, the correct answer is **Enocytes**, as they are the cells that secrete wax on the outer surface of the body wall.

5. **Final Answer**: The cells that secrete wax located at the outer surface of the body wall are **Enocytes**.
