Results obtained were as follows : 1) The blackflies were active for biting even in the winter season in this area. 2) During the period, a total of 6,266 adult flies (inculuding two males) of six species of the genus Simulium was captured, of which 1,957 (31.2%) individuals were engorged. 3) Simulium bidentatum comprized 80.9% of all the flies captured, followed by S. rufibasis 7.3%, S. aokii 6.9%, S. takahasii 2.6%, S. japonicum 2.1% and S. uchidai 0.1%. 4) S. rufibasis showed the highest rate of engorgement (39.8%), followed by S. bidentatum (31.9%), S. japonicum (31.6%), S. aokii (23.0%) and S. takahasii (8.5%) in this order. 5) The highest rate of engorgement was seen in December (45.2%), followed by January (35.6%), March (28.2%), February (27.1%) and November (25.0%).
