Abstract: The seasonal prevalence of immature stages of Aedes togoi in coastal rock pools was studied at Abumize, Fukue Island, Nagasaki by estimating the absolute number of larvae (pupae inclusive) in each pool by the modified removal method. The method we used was justified by the fact that the seasonal trend of larvae coincided very well with the trend of adults. The seasonal abundance of larvae was different in years but generally lower in summer. It was shown that the important factors influencing the abundance include (1) drying up of pools by direct sunshine and little rain fall, (2) water quality that is changeable byrain fall, sprays of sea water by strong wind, and the succession of microorganisms, and (3) natural enemies such as dytiscids (Coleoptera) and notonectids (Hemiptera).
