The Effects of Cold Shock on The Longevity in Oregon R wild and Vestigial mutant of Drosophila melanogaster (Diptera: Drosophilidae)

The affects global warming and climate change promise to be one of the most important environmental problem In the next millenium. It is indicated that,in increase in temperature by changes in global climate will not only happen at the same time. but some regions may incur in the sudden cooling. In this study, the effects of cold shock on the longevity of Drosophila melanogaster were analyzed. The flies used in the experiments were Oregon R wild type and Vestigial mutant type of D. melanogaster. For this study, a -3 degrees C cold shock was applied to the experimental groups it different durations (1, 2 and 3 hours). According to our results, it was observed that the mean female and male populations life span of the Oregon R wild type and Vestigial mutant type of D. melanogaster was reduced depending on the increase in the groups. duration on the experimental groups.
