An analysis of the effect of irradiation of the larval ovary on the number of ovarioles has been carried out. Two populations of Drosophila melanogaster with different irradiation background, namely one which had been subjected to irradiation at gonial stage during a large number of generations and the other, which was used parallelly as its control, were tested in this investigation. In the main, doses which do not cause any reduction in the number of individuals treated were applied. Irradiation causes an increase of the number of ovarioles in the females of both populations. The increase is significantly higher in populations which were not subjected to irradiation earlier.
