Aedes togoi is one of the medically important mosquitoes in the world as the female mosquitoes of this specie may bite human beings and may transmit filariasis. The feeding activity was found to be highest in night from 01:00-03:00 hours with indoor activity, most of the time, of the mosquito. It is commonly found in bedrooms and then at stock place, floor and kitchen. (Lee et. al., 1995).

In the different parts of South Korea in 1991, researchers found that the adult population of the mosquito usually appeared from the first week of April to the end of November showing the highest density in July (Lee et. al., 1995).

Larvae of this mosquito are commonly present in the coastal regions. Larvae are present in tidal pools or rock pools of salt and brackish water, also occasionally in containers with fresh water. The density of the larvae found in the different parts of the South Korea is highest from June to August. (Lee et. al., 1995)

Aedes togoi can become the vector of Brugia malayi, Wuchereria bancrofti, (both are found to be cause of lymphatic filariasis) Dirofilaria immitis (also the cause of filariasis) and Japanese encephalitis. Filariasis is the disease that inflames and obstructs the lymphatic glands, sometimes resulting in elephantiasis.

Recently researchers have reported that the IR3535 derivative (LJH158), in which the ethyl ester of IR3535 was converted to methyl ester, has potential repellant properties against Aedes togoi. (Sung Jin Park et. al., 2012).
