Abstract
Observation on the successions of larvae and pupae of mosquitoes breeding in basins for holy water hollowed on gravestones surrounded by bamboo groves were carried out in Kyoto from January to December, 1957. 946 individuals belonging to 4 genera including 6 species were collected, of which Aedes japonicus (30.7%), Aedes flavopictus (26.0%) and Uranotaenia bimaculata (24.5%) were large in number, Aedes albopictus (15.1%) was next to them, and Tripteroides bambusa (3.3%) and Armigeres subalbatus (0.4%) were rather rare. The seasonal prevalences of these species are shown in Fig. 1. Aedes japonicus and Uranotaenia bimaculata appeared all the year around and the former was dominant from October to early in May. Aedes flavopictus, Aedes albopictus and Tripteroides bambusa appeared from spring to autumn and Aedes flavopictus was dominant in summer.
