In this study it has been demonstrated that Drosophila immigrans females begin laying fertile eggs on the third or fourth day following eclosion, with productivity reaching a peak between the fifth and sixth days of adult life. A delay in mating of even four days decreases the rate as well as the volume of productivity. Based on the evidence in the literature, it is suggested that the stimulus to oviposition may be mechanical or chemical on the corpora allata via the ventral nerve cord.
