在许多昆虫类群中，雄性性成熟并不总是在成虫羽化时直接达到。性成熟通常在行为上被定义为交配成功，或者在生理上被定义为配子产生的时间点。在这里，我们表明，男性的性成熟过程比以前描述的更复杂，成熟度的衡量也需要包括交配后的特征。在许多物种中，交配成功与附属腺（AG）的大小密切相关。AG是一种复杂的蛋白质混合物的生产场所，这些蛋白质与精子一起沿着转移到雌性，并影响雄性生殖成功的重要功能。利用果蝇，我们进行了全面的行为测定的几个方面的男性生殖健康和证明，AG达到完全成熟的男性达到完全的生殖能力。我们测试了男性后不久，长达6天，成年后羽化，并考虑前和后交配性状。年轻的雄性不太可能获得交配，表现出明显较少的求偶行为。年轻的男性，设法获得交配，但在许多交配后的特点，如精子的竞争力和有效性，抑制女性再交配。我们在羽化后的前6天监测雄性AG的发育，发现它在整个期间的大小显着增加。
In a number of insect taxa, male sexual maturity is not always directly attained at adult eclosion. Sexual maturity is often defined behaviorally as mating success, or physiologically as the point when gametes are produced. Here, we show that the sexual maturation process in males is more complex than previously described and that a measure of maturity also needs to include post-mating traits. In many species mating success is tightly linked with size of the accessory gland (AG). The AG is the production site of a complex cocktail of proteins that are transferred to the female along with the sperm, and which impact on important functions for male reproductive success. UsingDrosophila melanogasterwe conducted comprehensive behavioral assays of several aspects of male reproductive fitness and demonstrated that the AG has to attain full maturity for males to reach full reproductive competence. We tested males from shortly after, and up to 6 days, post adult eclosion, and considered both pre- and post-copulatory traits. Young males are less likely to gain a mating and show significantly less courtship behavior. Young males that managed to obtain a mating however were inferior in many post-copulatory traits like sperm competitiveness and effectiveness in suppressing female remating. We monitored male AG development over the first 6 days after eclosion and found it to significantly increase in size over the entire period.
