Abstract
A greater percentage of Drosophila females entrain their egg laying rhythm to temperature cycles compared to light/dark cycles.
- Circadian egg laying behavior in Drosophila melanogaster is influenced by both light and temperature cues.
- Previous research indicates that activity/rest rhythms entrain easily to light/dark and temperature cycles.
- Egg laying rhythms showed two peaks when temperature cycles were paired with out-of-phase light/dark cycles.
- This suggests that temperature may more effectively entrain egg laying clocks than light does.
- The findings indicate that temperature and light can work together to influence circadian rhythms in egg laying.
