抄録: Seasonal changes of immature (preimaginal) stages of blackflies downstream of Yonoo River, Isahaya City, Nagasaki Prefecture were investigated in November, 1981 to January, 1983. Seven species, Simulium (Simulium) quinquestriatum, S. (S.) arakawae, S. (Odagmia) bidentatum, S. (O.) aokii, S. (Eusimulium.) uchidai, S. (S.) japonicum, and Prosimulium sp. were collected. S. (S). quinquestriatum was predominant species of 74% of the total specimens collected. Three species, S. (S.) quinquestriatum, S. (S.) arakawae, S. (O.) bidentatum were abundant in spring and autumn, but they were not collected in August and September. This is considered to have been mainly due to the high temperature and a great flood in July, 1982. The population was mainly composed of larvae in different developmental stages, throughout the year. Also in winter, from December to February, the larvae with different sized head capsules appeared and developed slowly during this period; they gradually pupated and emerged in March. This indicates that 3 species of S. (S.) quinquestriatum, S. (S.) arakawae, and S. (O.) bidentatum do not have such typical diapausing states in the larvae, as the larval diapausing states in Armigeres subalbatus mosquitoes.
