The disease filariases transmitted through the secondary host of wuchereria,it is

Options

A. anopheles
B. sand fly
C. Tse tse fly
D. Culex

Explanation

To answer the question regarding the disease filariasis and its transmission through the secondary host of Wuchereria, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: The organism responsible for filariasis is Wuchereria. Specifically, the species is Wuchereria bancrofti, which is known as the filarial worm.

2. **Understand the Disease**: Filariasis is a disease caused by the infection of Wuchereria bancrofti. This organism is a type of nematode (roundworm) that affects the lymphatic system.

3. **Determine the Hosts**: Wuchereria bancrofti has a complex life cycle that involves two types of hosts:
- **Definitive Host**: This is the host in which the adult worm lives and reproduces. In this case, the definitive host is humans.
- **Intermediate Host**: This is the host in which the larval stages of the worm develop. For Wuchereria bancrofti, the intermediate host is a mosquito.

4. **Identify the Mosquito Species**: The specific mosquito species that acts as the intermediate host for Wuchereria bancrofti is the Culex mosquito. Other mosquito species, such as Anopheles and Aedes, are known to transmit different diseases but are not responsible for filariasis.

5. **Conclusion**: Based on the above information, the disease filariasis is transmitted through the Culex mosquito.

### Final Answer:
The disease filariasis is transmitted through the secondary host of Wuchereria, which is the **Culex mosquito**.
