Abstract :
The amount and quality of nutrients consumed by organisms have a strong impact on stress resistance, life history traits and reproduction. The balance between energy acquisition and expenditure is crucial to the survival and reproductive success of animals. The ability of organisms to adjust their development, physiology or behaviour in response to environmental conditions. The availability of the food and nutrition is important factor for the flies or organism which copes with the various types of environmental stress. In the present study the flies of Drosophila melanogaster flies are cultured in the wheat cream agar media and caffeine media to understand the effect of caffeine on the Heat resistance. The results reveals that the caffeine fed flies had the greater resistance to the heat than the Wheat cream agar media which had the second least resistance to heat as well as the diet having highest concentration of caffeine had less resistance of heat than any other. Further in the present study, females are more sensitive to the heat resistance than those of the males which show greater tolerance to the heat, in all the three diets. Further among mated and virgin flies, virgin males and females were more resistant to the heat than those of mated males and females in all the three diets. Hence these studies suggests that caffeine slightly enhances the heat resistance results in D. melanogaster.
