Find the Incorrect match between disease and its vector.

Options

A. Disease -Bubonic plague ,Vector- Xenopsylla
B. Disease- Dengue , Vector-Anopheles
C. Disease-Chikungunya , Vector- Aedes
D. Disease-Filariasis ,Vector- Culex

Answer

To solve the question of finding the incorrect match between disease and its vector, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**:
We need to look at the options given in the question, which pair diseases with their vectors.

2. **Analyze Option 1**:
- **Disease**: Bubonic plague
- **Vector**: Xenopsylla
- **Evaluation**: This is a correct match. Bubonic plague is transmitted by the flea known as Xenopsylla cheopis.

3. **Analyze Option 2**:
- **Disease**: Dengue
- **Vector**: Anopheles
- **Evaluation**: This is an incorrect match. Dengue fever is transmitted by Aedes mosquitoes, not Anopheles mosquitoes.

4. **Analyze Option 3**:
- **Disease**: Chikungunya
- **Vector**: Aedes
- **Evaluation**: This is a correct match. Chikungunya is indeed transmitted by Aedes mosquitoes.

5. **Analyze Option 4**:
- **Disease**: Filariasis
- **Vector**: Q legs (Culex)
- **Evaluation**: This is a correct match. Filariasis is caused by parasitic roundworms and is transmitted by Culex mosquitoes.

6. **Conclusion**:
After analyzing all the options, we find that the second option (Dengue and Anopheles) is the incorrect match.

### Final Answer:
The incorrect match between disease and its vector is **Option 2: Dengue and Anopheles**.
