  • 1Division of Parasitology, National Institute of Health, Seoul, Korea.


Ecological studies of Aedes togoi, the vector of malayan filariasis, were carried out at Tolsando, Yosu and Sokcho area in 1991. The adult population of Aedes togoi was continuously appeared from the first week of April to the end of November showing the highest density in July. The larvae of Aedes togoi were found at rock pools from March to December in Sokcho area and the density was highest in July and August, whereas in the southern coastal area (Yosu), the larvae were found throughout the year and the density was the highest in June. The rate of larvae inhabited below 0.5% salinity was 45.7% in Sokcho and 51.7% in Yosu. The feeding activity of Aedes togoi was nocturnal, with the peak period of 01:00-03:00 hours. Indoor feeding activities were slightly higher than outdoors showing the biting ratio of 1:0.8 (indoor: outdoor). The average number of Aedes togoi attracted to CO2 gas was 8.5 whereas 117 Anopheles sinensis was attracted. The result indicates that CO2 is not an effective attractant for host seeking of Aedes togoi compared to Anopheles sinensis. The most common place was bedroom with 54.5% of total collections and next to stock place (18.2%), floor (9.1%) and kitchen (9.1%).
