Abstract: In the experiment on the diapause of Tripteroides bambusa, it was found that a few females showed the autogeny, a phenomenon which is defined here as the egg laying without blood meal, when they were transferred from the condition with high temperature and long photoperiod to that with low temperature and short photoperiod in the larval stage. In order to know more clearly the situation to induce this phenomenon, the larvae in each stage, the newly moulted pupae and newly emerged females were transferred from the condition with 25℃ and 16 hr daylength to the condition with 15℃ and 10 hr daylength. Those resulting females were supplied with 2% sugar solution and dissected 14 days after emergence to examine the follicular development. When the larvae over 2nd instar or the pupae were transferred from the condition with 25℃ and 16 hr daylength to the condition with 15℃ and 10 hr daylength, 6.0-24.1% of females had the follicles in stage V (mature egge) and the follicles in many of remaining females were in stage II or III. However, none of the females which had been transferred just after emergence or had not been transferred had the follicles developed beyond stage II. Also, the autogeny was observed in females which had emerged in spring from overwintering larvae collected in the field and reared outdoors. From those experiments, it will be said that the autogeny in this mosquito species is influenced by low temperature and short photoperiod in immature stage.
