Answer

To determine which disease is transmitted by the bite of a female mosquito vector, let's analyze the options provided in the question step by step.

### Step 1: Identify the diseases listed
The options given are:
1. Filariasis
2. Amoebiasis
3. Typhoid
4. Pneumonia

### Step 2: Understand the causative agents
Now, we will look at the causative agents of each disease to identify which one is transmitted by a mosquito.

- **Filariasis**: This disease is caused by the parasitic worm *Wuchereria bancrofti*, which is transmitted through the bite of infected female mosquitoes, particularly the *Culex* species.

- **Amoebiasis**: This disease is caused by the parasite *Entamoeba histolytica*, which is not transmitted by mosquitoes but rather through contaminated food and water.

- **Typhoid**: This disease is caused by the bacterium *Salmonella typhi*, which is transmitted through contaminated food and water, not by mosquitoes.

- **Pneumonia**: This disease is primarily caused by the bacterium *Streptococcus pneumoniae* and is not transmitted by mosquitoes.

### Step 3: Conclusion
From the analysis, it is clear that the only disease transmitted by the bite of a female mosquito vector is **Filariasis**.

### Final Answer
The disease transmitted by the bite of the female mosquito vector is **Filariasis**.
