Meteorological analysis of the 1967-1975 mosquito survey in Izumi-Mibayasi area of Osaka Prefecture revealed that the day of first appearance of overwintered females of Culex tritaeniorhynchus was strongly correlated with the cumulative temperature (day-degree) from February 21 to March 31. Most of the overwintering mosquitoes seemed to have completed diapause at latest by late February in this area. But, the first appearance of the-mosquitoes delayed in years when the cumulative temperatures during this period were less than 335. 1 daydegrees, and the mosquitoes began to be attracted to a dry ice trap when temperature at sunset was above 13℃ or mean daily temperature was above 14.5℃. Flight activity of the mosquitoes was also inhibited when the days in which mean daily temperature was below 14.5℃ increased in early or mid April.
