Abstract

Female age influence on male reproductive performance and also female fitness traits. The male recorded such as courtship activities, mating latency, copulation duration, and female fitness traits, such as, fecundity, has been used  from isofemale lines of Drosophila melanogaster. The female age including, 2-3 days aged old (young aged), 17-18 days aged old (middle aged) and 31-32 days aged old (old aged) mated with virgin male (5-6 days aged old) that all of the flies were exposure of middle temperature (22°c). The results of SPSS software analyzed that in almost all of experimental young aged old had significantly level than middle and old age. Courtship activities elements, in young age female were greater than middle and old age, when mated with young age male. This variability suggests that parental age effected on the male reproductive performance and female fitness traits. Therefore, the female age specific possibility occurrence on reproductive access as follows by: young aged> middle aged>old aged.
