Which of the following is an incorrect match of vector and the disease it transmits?

Options

A. Xenopsylla — Bubonic Plague
B. Culex — Elephantiasis
C. Aedes — Dengue
D. Phlebotomus — Sleeping sickness

Answer

To determine which of the following is an incorrect match of vector and the disease it transmits, we will analyze each option provided.

1. **Xenocila and Bubonic Plague**:
- The vector for the bubonic plague is actually the flea, specifically the rat flea (Xenopsylla cheopis). Therefore, this match is correct.

2. **Culex and Elephantiasis**:
- The Culex mosquito is known to transmit lymphatic filariasis, which can lead to elephantiasis. Thus, this match is also correct.

3. **Aedes and Dengue**:
- The Aedes mosquito, particularly Aedes aegypti, is a well-known vector for dengue fever. Hence, this match is correct as well.

4. **Flitombus and Sleeping Sickness**:
- Sleeping sickness is caused by the parasite Trypanosoma brucei, and its vector is the tsetse fly (Glossina), not Flitombus. Therefore, this match is incorrect.

Based on the analysis above, the incorrect match is:

**Flitombus and Sleeping Sickness**.

The correct answer is option 4.
