The present study investigated the effects of ethanol extract obtained from Punica granatum (Pge) on the longevity of Drosophila melanogaster Meigen. The effects of different concentrations of Pge (10.0; 30.0; 50.0 and 100.0mg/mL) were administered separately to female and male populations of D. melanogaster for the control and Pge groups. In all application groups, each population's longevity increased, depending on the concentration of Pge. These findings demonstrate that the constituents of P. granatum have great potential as a source for natural health products for D. melanogaster management.

It is known that there is a relationship between stress factors and longevity and many stress factors are effective on longevity and aging. One of the stress factors is temperature. Global warming, whose effects keep rising nowadays and better understood by the people, and climate changes depending on global warming are strengthening the effects of this stress factor. In this study, the effects of heat 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 39oC heat 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 (p<0.05 and p<0.001).
