Critical photophase for the vitellogenesis of Henosepilachna adults was 13 hr 50 min, and all the females developed their ovaries in photophases longer than 15 hr. In a short photophase of less than 13 hr, vitellogenesis was inhibited, but in very short photophases (0-2 hr) some females developed ovaries. Females in the oviposition period showed different reactions to short photophases. Most individuals ceased ovarian development under a 12 L-12 D regime but other short-day photoperiods lacked a complete inhibitory effect. It was estimated from the night interruption experiments that there were two light sensitive periods in the scotophase, i.e. 9-8 hr before dawn and 8-10 hr after dusk. It appeared that based on these data the measurement of the night duration could be performed so as to regulate the ovarian development. Adults were able to synchronize their ovarian development with photoperiodic cycles of more or less than 24 hr and showed typical photoperiodic-reaction curves in 28,16 hr cycles.
