Many studies found that the temperature has affected the fecundity and fertility in the female of Drosophila melanogaster. In this study we used male of 2-3 days age old and female of 5-6 days age old for studies of temperatures on the male reproductive performance and female fitness traits. In related to be compared three temperatures from low (15°c) temperature middle temperature (22°c) and high temperature (29°c), results were analysed by SPSS software for getting mean value , ANOVA variation and correlation relationship. In this regard, females which exposure to high temperature, among of egg laid and offspring produce (fecundity and fertility, respectively) less than middle and low temperature, that these results were significant, p value <0.000, between male and female with temperature and also between fecundity and fertility. The results of correlation relationship are shown; there was a significant Pearson correlation between three temperatures (low, middle and high) with the rate of egg laid and egg hatchability.

The effect of different temperature on the viability and fertility of Drosophila melanogaster
