Male Drosophila melanogaster differ in the age at which they reach sexual maturity following eclosion from the pupa. Courtship latency, which is the time taken by a male to initiate courtship of a conspecific female, is related to age. Young males take significantly longer than older males to begin courtship. The probability that a male will initiate courship is influenced by the physiological state of the female. Males of different genotypes readily court mature (3-day-old) virgin females, but they differ significantly in their reaction to immature (12-hr-old) and fertilized females. Genes located on the third chromosome largely control male courtship latency, but responses to immature and fertilized females have different genetic bases, suggesting that the relevant stimulus inputs governing these responses also differ. The adaptive significance of courtship directed toward immature or fertilized females, which rarely mate, probably depends on the average level of sexual responsiveness of potentially receptive mature virgin females in a given population.
雄性黑腹果蝇从蛹羽化后达到性成熟的年龄各不相同。求偶潜伏期，即雄性开始对同种雌性进行求偶所需的时间，与年龄有关。年轻雄性开始求偶的时间比年长雄性长得多。雄性开始求偶的概率受雌性生理状态的影响。不同基因型的雄性很容易向成熟（3日龄）处女雌果蝇求偶，但它们对未成熟（12小时龄）和已受精雌果蝇的反应有显著差异。位于第三条染色体上的基因在很大程度上控制着雄性的求偶潜伏期，但对未成熟和已受精雌果蝇的反应有不同的遗传基础，这表明控制这些反应的相关刺激输入也不同。针对很少交配的未成熟或已受精雌果蝇的求偶行为的适应性意义，可能取决于给定种群中潜在可接受的成熟处女雌果蝇的平均性反应水平。
