One of the most interesting problems in the natural history of the arthopod-borne viruses is their mechanism of survival during the interepidemic period. Mosquitoes overwintered and trapped in April and May by the dry ice-light trap had longer wings than the summer mosquitoes, while the mosquitoes caught in the fall had shorter wings than the overwintered mosquitoes, though an exceptional specimen of parous female was caught in the Mibayashi district (Fig. 1,Table 1). From the middle of September to October, the wing length of the blood-engorged females caught in the cow shed was as short as those of the mosquitoes collected by the dry ice-light trap. However, the wing length of the mosquitoes emerged from pupae caught in the paddy field, reservoir, and abandoned drain was longer than that of the blood-fed female. The wing length of these mosquitoes was about the same as that of the overwintered female (Fig. 1,2). Experimental data show that the specimens reared in low temperature and short photoperiod had longer wings than those grew in summer (Fig. 3,Table 2). These data indicate that the unfed, nulliparous female was predominant in the hibernating population, and this was probably induced to diapause by the autumnal, short photoperiod and low temperature.
