dc.description.abstract | The adult emergence rhythm of Telenomus busseolae, an egg parasitoid of Sesamia nonagrioides, was examined when parasitoids were exposed to different light-dark regimes. Most of the adult parasitoids emerged throughout the whole period of the photoperiodic cycle. Peak male emergence occurred 2-5 hours earlier than that of females. Adult emergence was asynchronous in continuous darkness or light. However, regimes of alternative light and dark phases such as L4:D20, L8:D16, L12:D12, L16:D8 and L20:D4 h generated a population rhythm with a period length of 24 hours. The peak of the emergence activity moves from the scotophase to the middle of the photophase with an increase of the photophase from 4 to 20 h. Rhythmical activity of adults was synchronised within 2 cycles when immature stages of parasitoid grow under continuous light conditions (LL) and then transferred to L12:D12. Moreover, emergence rhythm persisted and continued in a free-run with a period length of less than 24 hours by transferring a rhythmic culture from L12:D12 h to LL or RR (continuous red light) conditions, indicating the existence of a circadian rhythm. The ecological implications of the expression rhythm relate to better survival of the parasitoids. | en |
