Abstract :
Stress resistance in an organism may be influenced by various factors including morphological, physiological, behavioural changes and quality and quantity of diet. The current study demonstrates the effect of the different concentration of cerelac media on the cold resistance of D.melanogaster in Wheat cream agar media, (10%, 20%, and 30%) cerelac treated media. The results suggest that flies fed with different concentration of cerelac media had greater cold resistance than Wheat cream agar media. Cerelac media provides sufficient nutrition to withstand cold. The study also shows that female flies had more starvation resistance than that of males (virgin and mated) and unmated female flies had greater cold resistance than those of mated flies. Thus, this implies that carbohydrates and proteins in cerelac may play major role in increasing the cold resistance in D.melanogaster.
