Effect of energy drinks on resistance to starvation of drosophila melanogaster

Organisms require energy for growth, development, reproduction, resistance to environment variables. In the present study effect of synthetic and natural energy drinks on resistance to starvation has been studied using D.melanogaster. It was noticed that larvae fed on natural drink consumed significantly greater quantity of food compared to larvae fed on synthetic energy drink and normal media, Further larvae and flies grown on natural energy drink based media had significantly greater resistance to starvation than those larvae and flies grown in synthetic energy drink and normal media, furthermore larvae and flies first treated with sub lethal temperature (37˚C for 15min) and cold treatment (-4˚C for 15min) then subjected to resistance to starvation also yielded similar results, Females had greater resistance to starvation than unmated . In mated flies males had significantly greater resistance to starvation than females while the reverse trend was noticed in unmated flies. Thus, these studies suggest that natural energy drink has beneficial over synthetic energy drink in D. melanogaster
