Abstract

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.
