Abstract :
The quality and quantity of nutrients play a crucial role in influencing stress tolerance, life-history traits, and reproduction in organisms. The survival and reproductive success of animals depend on maintaining a balance between energy intake and expenditure. In this study, Drosophila melanogaster was raised on wheat cream agar and cerelac-based diets containing 10%, 20%, and 30% concentrations. Findings revealed that flies fed with 20% and 30% cerelac exhibited higher heat resistance than those on the 10% cerelac diet, which showed moderate resistance. Flies reared on wheat cream agar alone demonstrated the lowest resistance to heat stress. Additionally, female flies consistently showed higher heat resistance than males across all diet types. Among males, mated individuals had better heat resistance than unmated ones, while this difference was not evident in females. These results suggest that cerelac with its high protein contents increases heat resistance in D.melanogaster.
