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 an 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°C cold shock was applied to the experimental groups at 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 duration on the experimental groups.
The difference in terms of life span was statistically significant (p<0.05 and p<0.001) according to the control group.
