In plant containers, such as bamboo vase in graveyard, bamboo stub, tree hall and so on, Diptera larval associations, which are formed by various combinations of different species of mosquitoes and Eristalis, were usually observed. To know the factors which play an important role in forming these associations, the following experiment was made. The internodes of the canes of the bamboo Phyllostachis mitis, were used as a container instead of the plant container in natural state. They were set in the shady place of a hill in the campus of the Tohoku University, and filled with sterilized tap-water. In a few days after setting, Diptera larval association began to appear in these water, and with the lapse of time it changed into other ones. In this experiment, the larval fauna found in the water of each bamboo containers, of which bamboos were two months, three months, a year and a half, two years, and three years after budding, were compared and examined. The results are as follows : 1. The appearance of Diptera larvae was characteristic in the containers made of the bamboos of different ages. 2. The diverse distributions of Diptera larvae are likely to be defined by the difference in pH of the water and by the timely appearances of the gravid females. 3. In adult Eristalis, the selection in egglaying was recognized, but when its density was remarkably high, it became loose. 4. The larvae of eggs of Aedes flavopictus became extinct affected by the sudden rise of pH.
