Explanation
Microfilariae are the larval stage of filarial parasites that cause diseases such as lymphatic filariasis, also known as elephantiasis, and onchocerciasis, also known as river blindness. These parasites require an intermediate host, typically a mosquito, to complete their life cycle and spread the disease.
Out of the four options provided, Culex mosquito is the most common carrier of microfilariae. Culex mosquitoes are known to transmit the filarial parasite Wuchereria bancrofti, which causes lymphatic filariasis, as well as the filarial parasite Dirofilaria immitis, which infects dogs but can also infect humans.
Aedes mosquitoes, on the other hand, are known to transmit viruses such as dengue, Zika, and yellow fever. Anopheles mosquitoes are the primary vectors of malaria parasites, while Tabanus flies, also known as horse flies, are known to transmit various diseases in livestock but are not typically associated with the transmission of filarial parasites in humans.
