Abstract

This study is an investigation of three different ages, 2-3 days aged old (young),
27-28 days aged old (middle) and 52-53 days aged old (high) in male to test influence
of aging and temperature on male reproductive performance, female fitness traits and
also offspring fitness traits. The male reproductive performance including male
mating ability and mating success on the female fitness traits, that were examined
patterns of age dependence on the temperature behavior when exposed to high (29°c)
temperature. At 29°c, between three ages (young, middle and old) the among of
female fecundity and fertility was significantly reduced, compared to normal
temperature. There was a significant egg laid and egg hatchability between young,
middle and old age females (young>middle>old), also, in females that mated with son
flies obtained from male young, middle and old aged, the variation of fecundity and
fertility between females was significant, but the among of females fecundity and
fertility that were mated with son’s of male middle age was higher than young and old
age: (middle>young> old).
