A study was carried out on the impacts of temperature and light/dark regime on the Egg Development Time (EDT) of the cyclopoida copepod, Mesocyclops ogunnus in Lake Kinneret. It was found that EDT was 148, 33 and 20 hours under 15°C, 22°C, and 27°C respectively. EDT was different between the two regimes of 12/12 hrs light/dark and 24 hrs light. Egg hatching and survival were higher under 24 hrs light regime. The results of temperature and light regime impacts on EDT indicate ecological implication on cyclopoida copepod population dynamics in lakes. The implication of the results to the global warming trend is also suggested.
